Installing Wood Siding

Installing Wood Siding

By Tim Carter
©1993-2009 Tim Carter

Summary: Wood siding has been used on houses for hundreds of years. Engineered wood siding is an improvement on traditional siding as it allows us to make the most of our natural resources. If you want the best exterior wood siding, look for wood that contains natural preservatives and has vertical grain. Western cedar is a great wood siding species.

DEAR TIM: The house I grew up in had traditional wood lap siding. It seemed to wear like iron and it has a fantastic traditional look and feel. I would like to install some on a new home and wonder if it is still available and what is the best way to install it. Perhaps the biggest question is how do I make sure that paint will never peel or blister on this new wood siding? Phoebe H., Palo Alto, CA

DEAR PHOEBE: You know what they say don’t you? Imitation is the highest form of flattery. It seems like all of the non-wood siding products for years have copied the lap wood siding look. Aluminum, fiber cement and vinyl siding have had imitation lap sidings for years. This tells you that not only is the wood siding a timeless material, the lap siding look is perhaps the most popular. My wife and I love the real lap wood siding on our own home.

Lap wood siding is still available but you have to be sure you buy the right one. I prefer wood products that include preservatives injected by Mother Nature. Cedar and redwood are two such sidings. Both of these wood species have a considerable amount of natural preservatives. You may find other soft or hardwood siding materials, but only buy them if you can be sure they have been treated against wood rot.

Be sure to discuss wood grain orientation with the siding salesperson. The best wood siding has vertical grain. Less expensive wood sidings will sport flat grain. You can easily tell a vertical grain wood siding if you look at a freshly cut end. If you see ten, twenty or even 50 of the dark tree rings on the cut edge, the siding is indeed vertical grain. Flat grain wood siding may only have one, two or three dark tree rings visible on the end of a piece of siding. The vertical grain wood siding is more stable and the grain will not raise on the flat surface that you see once it is installed. 

Before you even think of nailing up your first piece of siding, there is a critical step you must follow. The wood siding needs to be primed on both sides and all edges before it is installed. Furthermore, each time you cut a piece of siding and are sure it is the correct length, those exposed cut ends must be painted before the siding is nailed to the wall. These critical painting steps help ensure the finish coat of paint will never peel or blister. I feel the best finish paint to use is one that is a blend of acrylic and urethane resins.

If the back and edges of the wood siding are not painted and water soaks into the wood, paint failure is an almost certainty. The water in the wood wants to get back into the atmosphere and it works its way to the front surface of the siding. Once there, warmth, wind and direct sunlight cause the water in the siding to form a vapor which can actually create a real blister in the finish paint. If you paint the back and edges of the siding, water can’t get into the wood in the first place.

The sides of the house must also be covered with a water barrier such as traditional asphalt-saturated felt paper or some of the modern synthetic fiber woven water and air barriers. You must use metal flashings and special drip caps moldings above horizontal trim boards, windows, doors and any other dissimilar material other than the siding. The flashings and drip caps help direct water away from the siding and prevent water from getting behind the siding or any trim boards used with the siding.

Be sure the first piece of wood siding or the lowest wood trim board laps over your foundation at least one inch. Water is your worst enemy and you want to ensure that water gets away from the siding and foundation of your home as quickly as possible. Follow all building codes with respect to the height above grade where the siding must start. Not all codes are the same, but I would not have the wood siding any closer to the soil than six inches. The greater the distance between the soil and the first piece of wood the better. If you can adjust your foundation height so there is a ten or twelve-inch space between wood and soil, do so.

The nails you use for wood siding are very important. The best nails are specific siding nails which have very blunt points and are made from stainless steel. These nails also have stacked rings on the shank of the nail for extra gripping power. Siding nails often have smaller heads as well so they are not that obvious if you install them flush with the surface of the wood siding. On painted siding, I always countersink the nail and fill the resulting hole with exterior spackling compound. 

To make sure the wood siding does not fall off the wall over time, be sure the nails used are long enough. The nail must pass through the siding, then pass through any sheathing such as plywood, foam board or oriented strand board and finally into a wood wall stud. The nail needs to penetrate the wood stud at least one and one-quarter inch. Do the math and you will discover it is best to use a nail that is 2.5 inches long.

  • Survey Says: Dealers Are Slowly Getting Greener, but Skepticism Persists

    In March 2009, PROSALES magazine conducted an online survey of LBM dealers, distributors, and manufacturers regarding the state of the green construction movement in their communities as well as whether they had taken action to green their own operations. The Survey indicates dealers are getting more active in green issues, even though a significant number say there’s little demand to do so. A small majority of dealers responding to the nationwide, online poll said they’re getting asked more often these days about green, but 41% still categorize interest in their area as nonexistent or barely there.

ENVIRONMENTAL BENEFITS OF WOOD

Environmental Benefits


Green by Design: Renewable, Durable, Sustainable Wood

The ATHENA™ Sustainable Materials Institute’s ultimate goal is to encourage the selection of material mixes that will minimize the environmental impact of a building over its life-cycle. The ATHENA computer model was used to compare alternative wood, steel and concrete structural designs for a three-story office building. The ATHENA findings are the result of a five-year research program involving architects, environmentalists, economists, engineers, and representatives from the steel, concrete and wood industries. ATHENA™’s life-cycle research found that wood building products have the lowest environmental impact when compared to other major building materials, based on raw materials and energy use, emissions to air, water and land.

What are the facts?

  • Total energy use: The wood building used the least energy. The concrete option required 1.7 times the energy for wood. The steel option required 2.4 times the energy. Wood simply does not require much energy to manufacture.
  • Greenhouse gases: The wood building had the lowest greenhouse gas emissions. The steel building generated 1.45 times and the concrete building generated 1.81 times the greenhouse gases for wood.
  • Air pollution: The wood design had the lowest air pollution index. The steel building produced 1.42 times and the concrete building produced 1.67 times the air pollution index.
  • Solid waste: The wood design had the lowest solid waste. This takes into account both manufacturing and on-site construction waste. Steel produced 1.36 times and the concrete produced 1.96 times the solid waste. This means there is virtually no waste during the manufacturing process and the use of engineered wood products has radically reduced the on-site construction waste.
  • Ecological Resource Use: The wood design had the lowest ecological resource use index. Steel was 1.16 times and concrete was 1.97 times the index for wood. This factor compares the long-term effects of resource extraction. Although forestry affects a large area, reforestation means the effects are short term. Sustainable forest management practices help ensure that disruption is minimized.
  • Conclusion: The office building built with wood had lower environmental impact for energy use, greenhouse gases, air and water pollution and ecological resource extraction than the steel or concrete building. A similar case study of residential buildings (comparing wood, steel and concrete construction) produced similar findings in terms of wood’s superior environmental performance.

These facts and others based on the ATHENA life-cycle findings can be found in a new primer put out by the Canadian Wood Council & the Forest Products Association of Canada have put out a primer, “Green by Design”.

“Green By Design: Renewable, Durable, Sustainable Wood.” Canadian Wood Council & Forest Products Association of Canada. (CWC & FPAC)

A primer on the environmental comparisons of wood and other materials in home and building construction.

This brochure explains why asking for Canadian wood products is the best environmental choice. It shows how taking a life cycle approach to building design will result in wood being the winner over competing products such as steel and concrete.


Addressing Negative Perceptions and Campaigns

According to the Wood Promotion Network, the last five years have witnessed mounting efforts by competing industries and environmental groups to reduce the market for wood. Their recent studies show that between 1997 and 2000 lumber alone lost 2.5% of the residential market for floors, walls and roofs. Significant environmental campaigns have been aimed at putting pressure on major corporate buyers of wood products. As a result, the public has been led to believe that forest are diminishing, that industry practices are not sustainable, and that the world needs to use less rather than more wood.

The Wood Promotion Network is N. America’s largest ever coalition of wood product and allied industry companies and related associations, representing more than two-thirds of N. American wood production. These companies have joined together to educate builders, DIYers and homeowners throughout North America on the benefits of wood building materials and the abundance of today’s North American forests.

Thus, the WPN goals are to secure and expand wood markets in N. America and to increase confidence about forest abundance and sustainability. While the goals may seem ambitious, the hard facts show that wood is the best environmental choice, hence it is not surprising that their campaigns to date have resulted in major achievements in terms of improving building and consumer perceptions of wood.

What are some of the messages that the Wood Promotion Network gets across:

  • N.America’s forests are abundant and growing, based on satellite imagery.
  • Wood is the best insulator against heat and cold, which makes it the most energy efficient material that can help keep home energy bills in check.
  • Regardless of market volatility, wood is the most affordable building material you can use. Framing an average 3-bedroom home can cost up to 30% less with wood versus other framing materials.
  • New innovations in engineered wood products and pre-made panels and trusses help builders and homeowners keep framing costs down. (WPN AR2001).
  • The production and use of wood is easier on the environment than any other building material. It takes less non-renewable fossil fuels and less energy to produce wood framing materials than alternative framing materials. (WPN AR2001).
  • Wood is the world’s only 100% renewable building material and is manufactured with the organic power of solar energy. (WPN AR2001).
  • Wood is the only major building material that is renewable. Canada’s sustainably managed forests ensure that there is an ample supply. New manufacturing technology allows every part of the tree to be used so that nothing is wasted. Advanced engineered wood products make use of fast growing species to produce high strength products without requiring large dimension timbers to meet building needs. (WPN AR2001).

Build with Wood and Help Protect the Environment

Over 80% of Canadians believe that sustaining the environment is a major priority. Many of us do our part, by recycling newspapers, refusing or reusing shopping bags, and composting waste.

But we may not realize that we make a much bigger impact on the environment through our choice of building materials.

Due to sustainable forestry practices, the volume of wood in Canada’s productive forests increased by 35% between 1976 to 1991. Last year alone, over 700 million seedlings were planted. That’s about 25 trees planted for each Canadian.

But how do we replace the thousands of tons of ore that went into steel beams or aluminum siding, or the millions of litres of petroleum that went into making plastic components?

The answer is – we can’t. Those resources are finite. Once we consume them, they are gone forever.

A study by the Canadian Research Alliance examined the relative environmental impacts of various building materials. The results clearly demonstrate not only that wood is a renewable resource, but also that the manufacture of wood products is cleaner, less wasteful, and consumes less energy than the alternatives.

Life-cycle analysis shows that a steel wall requires 3 to 6 times more energy to extract, manufacture and construct than a wood wall. The steel wall also uses 25 times more water in its manufacture, and releases 3 to 6 times more carbon dioxide emissions.

The manufacture of concrete produces 2 to 3 times more carbon dioxide than wood, and results in 5 times more solid waste.

The production of aluminum generates 8 times more polluting emissions in the air and 300 times more in the water, than the manufacture of wood. The manufacture of aluminum siding requires 5 times more energy than wood.

Construction is a $25 billion a year industry in Canada. That’s the equivalent of almost $900 for each Canadian, much of it spent on building materials.

Selecting Environmentally Friendly Flooring

Wood flooring is renowned as a feature that wears well and minimizes the accumulation of dust and microbes. And the engineered wood products used for sheathing and for beams and joists are made with glues that don’t contribute to allergies.

Thinking of replacing that worn flooring in the front hallway?

By shopping around, you can get information about the price, style, and maintenance of commonly-used flooring products.

It is much harder to learn about the hidden impact of these products on the environment. To make an informed choice, consumers also want to know about the composition and manufacture of various flooring materials.

Synthetic sheet flooring, such as cushion flooring, is made from non-renewable petroleum resources. Because it is non-biodegradable, scraps cannot be recycled. The manufacturing process is energy-intensive, depleting the supply of fossil fuels.

Ceramic tiles are made by firing clay, a plentiful resource. However, the kilns used to fire the clay consume large quantities of energy. Ceramic tiles are not recyclable.

Linoleum is made with renewable ingredients (linseed oil, cork, wood dust and dyes) that have been heat-cured and sealed, but it is not recyclable. Various chemicals are used for manufacturing, although less than are required for synthetic floor materials.

So what can you select that is environmentally friendly as well as being durable, easy-to-care-for, beautiful and affordable?

The answer is wood. Oak and maple hardwood flooring – solid plank, pre-finished wood flooring systems, parquet tiles and veneer – comes from wood, a renewable resource. Part of the energy used in the manufacturing process comes from wood waste materials.

Veneer flooring is comprised of a surface of high quality hardwood laminated to a plywood or particle board backing, and packaged as tiles. Wood fibre waste from low grade wood is used in the backing, and high-grade wood is used in the surface veneer.

When you’re shopping around, ask your retailer or contractor for more information from the flooring manufacturer. That way you can select a product that is attractive to the environment AND to your home.

Build that New Fence with Wood and Help Protect the Environment

When you shop for materials to build your new fence or deck, you probably think about things like appearance, ease of installation, and cost. But what about the cost to the environment of the building materials that we buy?

Over 80% of Canadians believe that sustaining the environment is a major priority. Many of us do our part by recycling newspapers, adding extra insulation in our homes, and walking to the video store at the corner instead of driving. But we also make a major impact on the environment when we choose building materials, often without realizing it.

Wood is a popular and attractive choice for many outdoor landscaping projects. Due to sustainable forestry practices, the volume of wood in Canada’s productive forests increased by 35% over the last 20 years. Last year alone, about 700 million seedlings were planted. That’s over 20 trees planted for each Canadian.

But what about that chain-link fence, those concrete patios stones or that vinyl lounge chair? How do we replace the thousands of tons of ore that went into the manufacture of steel, or the millions of litres of petroleum that went into making plastic components?

The answer is – we can’t. Those resources are finite. Once we consume them, they are gone forever. And the manufacturing process has added to the world’s pollution problems.

A study by the Canadian Research Alliance examined the relative environmental impacts of various building materials. The results clearly demonstrate that the manufacture of wood products is cleaner, less wasteful, and consumes less energy than the alternatives.

Life-cycle analysis shows that a steel wall requires 3 to 6 times more energy to extract, manufacture and construct than a wood wall. The steel wall also uses 25 times more water in its manufacture, and releases 3 to 6 times more carbon dioxide emissions.

The manufacture of concrete produces 2 to 3 times more carbon dioxide than wood, and results in 5 times more solid waste.

The production of aluminum generates 8 times more polluting emissions in the air and 300 times more in the water, than the manufacture of lumber. The manufacture of aluminum siding requires 5 times more energy than lumber.

So when you go to buy the materials for that new fence or deck, consider the alternatives – and make an informed choice.

Sustainable Forest Management

Key Facts on Sustainable Forestry in Canada

Size
About half of Canada’s land mass is covered by forest, that is approximately 417 million hectares. Only ¼ of Canada’s forests are dedicated to forest management (119 million hectares), the remainder, for example, is either protected from harvesting, is of a non-commercial quality, or is commercial but not yet accessed or allocated.

Ownership
94% percent of Canada’s forests are publicly owned, while the remaining 6% is private property belonging to more than 425,000 landowners.

Harvest Levels
Canada harvests less than ½ of 1% of its commercial forest area each year, or ¼ of 1% of its total forest area. Moreover, it grows twice as much timber as it harvests. About ½ of the Canadian forest will NEVER be harvested. That never-to-be-logged Canadian forest is larger than California, Arizona, New Mexico, Texas and Louisiana combined.

Fire, Insects & Disease
Did you know that Canada harvests less of its commercial forest each year (0.4%) than is taken by fire, insects and disease (0.5%).

Regeneration
By law all forests harvested on Canada’s public lands must be replaced. . More than half of the area harvested in Canada is left to regenerate naturally. Many tree species can reestablish themselves on a site without planting or seeding. These natural mechanisms include seeding from the adjacent forest, suckering of stumps and roots, and growth of young trees remaining on the harvested area. In summary, regeneration is accomplished by natural regeneration (53%), planting (43%), and aerial seeding (4%).
An Abundant and Growing Forest
The area of trees growing in Canada is growing not shrinking. In fact, during the 5 year period, 1990-1995, the United Nations FAO estimated a net increase of 4% in the area of trees growing in Canada’s commercial forests.
Helping Our Climate
Trees are living plants that ‘breathe’ to help them grow. As they breathe, they remove unwanted carbon dioxide from the air – a greenhouse gas that contributes to global warming – and replace it with life sustaining oxygen.
Park System
Canada is the world leader in terms of area dedicated to its national and provincial park system for the use and enjoyment of Canadians and citizens around the world. Its national and provincial parks alone occupy some 56.8 million hectares. Compare that to the area of forests managed primarily for wood production in Canada – 119 million hectares – and one can quickly see that Canada’s forests are maintained for a variety of values and uses.
Original Forest Cover
Almost half of the Earth’s original forest cover is gone, much of it destroyed within the past three decades. In contrast, Canada has maintained over 90% of its forest cover and it has done so while being one of the world’s largest producers of high-quality forest products.
Forest Certification
Certification provides proof that forests are being managed by an independent 3rd party audit. Currently, if including CSA, SFI, FSC and ISO 14001 certifications, Canada has certifications covering some 115 million hectares of forest land- the largest certified forest area in the world! If however, one considers only those certifications to forestry-specific standards such as CSA, SFI, FSC, Canada has over 25 million hectares of forest land certified – of which 1 million is certified to FSC (see next bullet). However, the area of certifications to forestry-specific standards (CSA, SFI, FSC) is scheduled to grow considerably by 2006 given a new commitment by the Board of FPAC. It is also important to remember that the vast majority of wood coming from Canada’s forests are well-managed, certified or not. For more information on the forestry specific standards noted above or on forest management certification status in Canada, visit www.CertificationCanada.org.

FSC Forest Certification
Forest Stewardship Council (FSC) certification is not practical for small 10-100 acre parcels of land which are the primary source of high value hardwood in Canada. Costs to implement and maintain an FSC certification would be higher than the value of product derived. To be brief, FSC on small private lands managed for timber is conceptually unworkable in Canada. This point is made given that many environmental organizations lobby purchasers of Canadian forest products to specify FSC certified wood – this is an unrealistic demand for most small private woodlots in Canada. It should also be noted that even large scale commercial forestry operations in Canada for the most part are not pursuing FSC certifications for a variety of reasons. To date, 1 million of 25 million hectares of certified forest land in Canada is certified to the FSC Principles.

Canadian Forest Lands

Sustainable Forest Management


Canada’s Forests – So Little Used – So Much Protected

How big are Canada’s forests?

  • 417 million hectares of forested land – the boreal and temperate forests cover approximately half of Canada’s landmass, about 417 million hectares.
  • 234 million hectares of forest with commercial potential – occupying a space about as large as the Mediterranean Sea.
  • Only ½ of the commercial forest, (or about ¼ of the total forest) are managed primarily for timber production, while the rest remain inaccessible or have not been allocated for that purpose.
  • What is harvested? Only 1 million hectares per year, that is less than ¼ of 1% of the total forest area.
  • How much parkland? Canada is the world leader with its national and provincial parks alone occupying some 56.8 million hectares. Compare that to the area of forests managed primarily for wood production in Canada – 119 million hectares – and one can quickly see that Canada’s forests are maintained for a variety of values and uses.

Source: Based on info found in the State of Canada’s Forest Report 2001/2002 produced by NRCAN.


How Much Wood Is Harvested in Canada Annually?

  • Did you know that the forest industry harvests less wood each year than is destroyed by wildfire, disease and pests?
  • In fact, Canada harvests only about ¼ of 1% of its forest lands.
  • Did you know that the Canadian forest sector harvests four times less (proportionally) than the five largest European forest nations combined?
  • Due to ever improving sustainable forestry practices, the volume of wood in Canada’s commercial forests just keeps on growing. In fact between 1976 and 1991 it increased by 35%.
Country Volume Harvested Total Forested Land
Canada 190 million m3 417 million hectares
Europe* 195 million m3 100 million hectares

* Sweden, Finland, Norway, France & Germany combined


How Extensive is Canada’s Original Forest Cover and Park Lands?

Almost half of the Earth’s original forest cover is gone, much of it destroyed within the past three decades. In contrast, Canada has maintained over 90% of its forest cover and it has done so while being one of the world’s largest producers of high-quality forest products. The CLA considers this fact to be instrumental in getting across the message that Canada is a leader in sustainable managing the natural forest, and it continues to improve based on the integration of new knowledge, information, research and development.

Not only does Canada maintain the highest percentage of original forest cover and untouched forests in the world, the reality is Canada’s forest industry has spent the better part of the last two decades making enormous strides in its forest management techniques, in lessening its environmental footprint – all in recognition of its role in the stewardship of a valued world resource. These achievements point to our ability to continue to be leaders in the management of natural forests using all three pillars of sustainable development: social, economic and environment.

Likewise, Canada is the world leader in terms of its national and provincial park system which now occupies some 56.8 million hectares. Moreover, this network of national and provincial parks continues to expand. For example, in October 2002, Prime Minister Jean Chretien announced that Canada plans on creating 10 new national parks over the next five years to protect unique landscapes and animals in the world’s second largest country. The total area covered by the 10 new parks will be around 100,000 square kilometers, almost doubling the area occupied by the existing 39 national parks.

“Canada is blessed with exceptional natural treasures. We owe it to Canadians and to the world to be wise stewards of these lands and waters,” Prime Minister Jean Chretien said in a speech to mark the announcement.


Forest Types, Ownership & Legislative Approach

  Forest Types There are more than 30 species of softwoods and 100 species of hardwoods in Canada. Most of Canada’s commercial lumber and wood products come from softwoods, which are more plentiful, however, there are numerous high-end, value-added products predominantly produced from Canada’s hardwood forest resource.

Softwood is the term commonly used for coniferous trees. These are trees that bear cones and have needle-like leaves which generally remain green throughout winter. Softwoods include spruce, pine and others.

Hardwood refers to deciduous or broad-leaved trees, such as maple and oak. The leaves change colour in autumn and are usually shed before winter. Hardwoods tend to be denser and therefore harder than softwoods.

  Forest Ownership & Responsibility Public Lands – Canada is unique in that 94% of its forest lands are publicly owned. Under the Canadian Constitution, the provinces have ownership over most publicly owned forest land—71% of the total forest land—and are legally responsible for it. The federal government’s responsibility for forests is based on its ownership of 23% of Canada’s total forest land, most of which is located in the territories. The federal government has, however, devolved responsibility for management to the territorial governments (devolution to the Government of the Yukon is to be completed in 2003).

Private Lands – Six percent of Canada’s forest land is owned by an estimated 425 000 individuals, families, communities and forest companies. Click here for more information on private lands in Canada.

 

Legislative Approach – Today, each province or territory has its own legislation, regulations, standards and programs through which it allocates forest harvesting rights and management responsibilities. About ¼ of 1% of Canada’s forests or about one million hectares are harvested annually. Each province or territory establishes Annual Allowable Cuts, which are based on the average volume of wood that may be harvested under sustained yield management. More than half the harvested area is left to regenerate naturally, usually after some form of preparatory site treatment. The remaining areas are seeded or replanted. Roughly 1.6% of Canada’s forests are affected by fire, insects and disease each year, and they are also left to regenerate naturally.

In addition, many provinces and territories have legislation that provides for public participation as part of the forest management planning and allocation process. The broad spectrum of forest user—the public, forest industries, Aboriginal groups and environmental organizations—are consulted in order to ensure that recreational, cultural, wildlife and economic values are incorporated into forest management planning and decision making.

In addition to provincial forestry legislation, there is federal legislation to ensure water quality is maintained and it is also working towards introducing federal legislation for species at risk. For example, in 1992, Canada became the first industrialized country to ratify the UN’s Convention on Biological Diversity. In doing so, Canada committed itself to ”Develop or maintain necessary legislation and/or regulatory provisions for the protection of threatened species and populations.” To fulfill this commitment, Canada has been working toward an improved protective framework for species at risk. In October 1999, the federal government committed itself to bringing in a new Species at Risk Act (SARA) as one of its first environmental priorities for the new millenium. Bill C-5 the Species at Risk Act, was passed by the House of Commons and tabled in the Senate in June 2002. The law is expected to be passed by the end of 2002″.

Focus On Hardwoods From Canada

Canada has a large hardwood resource. The Allowable Annual Cut (AAC) has been calculated and set at 65 million m3 per year. The harvest level is approximately 35 million m3 per year or 55% of the AAC.

There are two broad categories of hardwoods in Canada:

  • Aspens and poplar (which require full sunlight to grow) – used mainly for wood- based panels, such as plywood and Oriented Strand Board (OSB) and for hardwood Kraft pulps and papermaking.
  • Tolerant hardwoods (so called because they are tolerant of shade. They also regenerate naturally when managed under partial-cut or selective harvesting systems). -used for lumber, veneers, furniture, cabinet making, flooring, and other value-added products with the low-grade logs being used for pulpwood or fuel wood depending on the marketing.

Canada has about 25 commercial species of tolerant hardwoods. 15 species are found in small quantities. Approximately 10 species are of significant economic importance.

Tolerant hardwoods found predominantly in Canada’s three eastern Forest Regions:

 

The Deciduous Forest Region- predominantly hardwood 0.4 million hectares
The Great Lakes- St. Lawrence Region- a mixed-wood forest 24.5 million hectares
The Acadian Forest Region- a mixed-wood forest 8.8 million hectares
Total Area 33.7 million hectares

Of Canada’s multiple-use forest land, approximately 23.4 million hectares, or 11% is in private ownership. 18 million hectares of the privately owned forest land lies in 5 of the eastern provinces with the vast majority falling within the three forest regions where the Tolerant Hardwoods grow.

Approximately half of the area of these three forest regions is in private ownership. Families own almost 75% of the private land as farm woodlots that average 40 ha in size. These lands tend to be the most productive and produce large volumes of tolerant hardwood logs. The area that is in public ownership is managed under strict provincial government regulation that ensures respect for the AAC, environmental guidlines and prompt regeneration after harvest.

In Canada stands of tolerant hardwoods, whether in public ownership or owned by industry or families, are managed and harvested using several partial cut or selection systems. Little planting is required after harvest, as natural regeneration is usually abundant.

Focus on Private Woodlots

Private woodlots are an important part of the sustainable forest management (SFM) equation in Canada. There are an estimated 425 000 woodlot owners in Canada who collectively own more than 18 million hectares of commercial productive forest land, which represents more than 12 percent of Canada’s total. Woodlots are an important source of commercial timber providing an annual harvest of 39.6 million cubic metres, or 21 percent of the national harvest¹. Equally, if not more important to woodlot owners, woodlots provide habitat, biodiversity, clean water, and spiritual and recreational opportunities.

(Source: http://www.modelforest.net/e/home_/privwoodse.html)

  • Six percent of Canada’s forest land is owned by an estimated 425 000 individuals, families, communities and forest companies.
  • If we compare the size and annual production of Canada’s family owned private forests to the listing of forest statistics for member countries of the FAO we find that these forests would be 13th in area and annual production – somewhere between Finland and France. The wood from private woodlots forms an important part of the 180 million m3 annual raw material requirements of the Canadian forest products industry. The woodlots have a significant presence in the southeastern regions of Canada, and are the source of a high proportion of Canada’s tolerant hardwoods.
  • These privately owned forests, of which 80% are located east of Manitoba and mostly in the Atlantic provinces, are generally productive and of high quality. They are the source of 19% of Canada’s industrial roundwood production (logs, bolts and pulpwood), 77% of maple products, 79% of fuelwood and firewood, as well as most of the nation’s Christmas trees.

Western Red Cedar For Indoor Use

INDOOR PRODUCTS | PROPERTIES

Resistance to Decay
Western Red Cedar heartwood is renowned for its high decay-resistance. This natural durability is attributed to the presence of extractives, mainly the thujaplicins, and to a lesser extent, the water-soluble phenolics which are toxic to a number of wood rotting fungi. Western Red Cedar has a durability Class 2 in Europe and Australia, the highest category for durability of any softwood listed.
 

Dimensional Stability
Western Red Cedar wood has excellent dimensional stability because of its low wood density and low shrinkage factor. A major contributor to this stability is the fact that its moisture content at the fibre saturation point is 18 to 23%, compared to 25 to 30% in most Canadian softwoods. As a result, Western Red Cedar shrinks and swells minimally, displaying only small movements with changes in humidity. Lower absorption of water is a result of the high extractive content blocking absorption sites. This property contributes to Western Red Cedar’s suitability for use in paneling, mouldings and a number of other applications such as saunas where dimensional stability and water repellency is important.

Thermal and Insulating Properties
Western Red Cedar has good insulation value because of its low wood density and coarse texture. It is the best insulator among the most common available softwood species and is far superior to brick, concrete and steel. This property ensures that homes built with Western Red Cedar will be cooler in the heat of summer and warmer in winter as opposed to homes using denser species or man-made products. Western Red Cedar’s ability to dampen vibrations is an important acoustical property which makes it particularly effective as paneling and moulding where it is desirable to reduce or confine ne noise.

Flame Spreading Rate
The flame-spread rating of Western Red Cedar is 67 to 73 (Class II rating) and the smoke developed classification is 98. Both of these are used to regulate the use of materials where potential to generate smoke or smoke control movement is important. Due to its low flame-spread rating, it will perform better than most dense softwoods which have flame-spread ratings around 100. Western Red Cedar has a flame spreading rate and a smoke-developed classification that are considerably below the maximum limits set by most building codes.

Finishing and Workability
The lack of pitch or resinous extractives that are soluble in paint vehicles contributes to Cedar’s good finishing properties. Cedar takes a variety of coatings, paints and stains exceptionally well, particularly when dried and properly primed. Western Red Cedar is among the easiest timbers to work with because of its straight grain and uniform texture. It planes and sands cleanly and, because of its low wood density, requires little energy to saw or otherwise work. Cedar also glues well with a wide range of adhesives and gluing conditions.

Cedar Siding Treatment

Q: What do you recommend for treatment of cedar siding?

— Mary, Kansas City, Missouri

A: Tom says: Cedar wood does contain a lot of tannic acids, especially red cedar, but in general, cedar doesn’t have to be treated that differently than other woods. But really I need to know whether you want to leave the cedar clear. If so, there are several excellent products out there for cedar siding and decks, which you should be able to find out about by consulting a professional at your local hardware store. One thing to remember is that you’ve got to make sure your cedar is clean and dry when you apply these finishes. On the other hand, if you want to paint the cedar siding, it’s got to first be primed, cleaned and prepped. As I said, the preparation is the most important step in any kind of painting you do: the surface has to be clean and dry. And depending on your situation, if you can get the cedar and let it weather a little bit, a lot of the tannic acids will come out, so it’ll be easier to paint. If not, and you painted it white for instance, sometimes the tannic acids will bleed through the white and that can be difficult to hide. A good primer followed by a latex top coat, or just a solid-body paint, or else a stain would be your best bets, being sure to follow the manufacturer’s recommendation on all.

LUMBER MARKETS EXPECTED TO REACH NEW LOWS
BEFORE STARTING SLOW HISTORIC LOW RECOVERY IN 2010

PORTLAND, Ore. – Demand for lumber in the U.S. in 2009 will slide to the lowest level in modern history, then move toward a slow recovery starting next year, according to a new forecast issued by Western Wood Products Association.
The poor economy and a housing market that has plummeted to historic lows are the chief reasons for the remarkable decline in lumber demand. WWPA predicts U.S. lumber demand will slide this year to just 28.9 billion board feet, down almost 30 percent from 2008 totals.
Since reaching an all-time high of 64.3 billion board feet in 2005, U.S. demand for lumber has dropped by more than 55 percent – the steepest decline in the history of the industry.
Home construction traditionally accounts for more than 45 percent of the lumber used each year. The Association estimates just 432,000 houses will be started in 2009, down more than half from 2008 totals and one-fifth of what was built in 2005.
The volume of lumber used in new home construction is expected total 5.3 billion board feet this year, compared to the 27.6 billion board feet consumed in home building in 2005.
In 2010, housing is forecast to improve modestly to 553,000 starts, bringing lumber consumption to nearly 30 billion board feet. WWPA does not expect housing starts to exceed
1 million units until 2012.

The unprecedented decline in demand has taken its toll on lumber producers. Western lumber production is forecast to decrease nearly 26 percent to 9.7 billion board feet. That volume is the lowest since the 1930s and represents a little more than half the volume Western mills produced five years earlier.
Mills in the U.S. South will see production declines as well, falling to 10.9 billion board feet in 2009. In all, U.S. lumber production will total 21.8 billion board feet this year, down 25 percent from 2008. As markets start turning up in 2010, U.S. production will rise to 22.4 billion board feet.
Poor markets have been even tougher on Canada and other foreign lumber suppliers. Lumber imports from Canada are predicted to total 7.6 billion board feet in 2009, a decrease of 34.7 percent from the previous year. Since 2005, Canadian lumber imports have declined by nearly two-thirds, or some 14 billion board feet.
Other imports, including lumber from Europe and Latin America, should decline by double-digit percentages for the fourth straight year and lose more market share to domestic producers.
Western Wood Products Association represents lumber manufacturers in the 12 Western states. Based in Portland, WWPA compiles lumber industry statistics and provides business information services to mills. The Association also delivers quality standards, technical and product support services to the industry.

Cedar Sustainability

03-27-09
Dimensional Stability – Cedar offers low density and shrinkage factors, and exceptional thermal insulation value.

Workability – Cedar is easy to cut, form, glue and finish.

Natural Preservative – Cedar contains natural preservatives that resist moisture, decay and insect damage.

Flame Spread and Smoke Development Ratings – Cedar exceeds safety classifications and does not require preservative treatments.

All-Weather – Cedar is naturally at home in the sun, rain, heat and cold all year round.

Dimensional Stability
Western Red Cedar has twice the stability of most commonly available softwoods. The stability is a result of its low density and shrinkage factors. It lies flat, stays straight, and holds fastenings tightly.

Workability
Western Red Cedar produces long, lightweight lengths of timber with a fine, straight grain and uniform texture that make it easy to cut, saw and nail with common tools. These features also contribute to its ability to be planed to a smooth surface or machined to any pattern. The lack of pitch and resin allows Western Red Cedar to hold glue bonds from a wide range of adhesives and provide a firm base for many types of paints and stains.

Natural Preservative
Western Red Cedar is one of the world’s most durable woods. Natural resistance to moisture, decay and insect damage has long made Western Red Cedar the premier choice for either interior or exterior home use. Cedar fibers in the heartwood contain natural preservatives that are toxic to decay-causing fungi. The two principal extractives that are responsible for the decay resistance are Thujaplicans and water-soluble phenolics. The tree’s ability to produce these extractives increases with age, making the outer regions of heartwood the most durable.

Flame Spread and Smoke Development Ratings
Western Red Cedar has flame spread and smoke development classifications that are superior to the minimums set by most building codes, which permit the use of cedar heartwood without preservative treatments.

All-Weather
Western Red Cedar is one of the few wood species that are naturally at home in the outdoors. Properly finished, Western Red Cedar will last for decades, even in harsh environments. Its natural resistance to moisture, decay and insect damage make it the ideal choice for a surface that is exposed to sun, rain, heat and cold all year round.

cedar prices remain stabile

03/26/2009 -  Despite the failing economy over the past year cedar prices have remained somewhat stabile and will even begin to rise in the coming months as demand starts to rise again.  Cedar siding, both in western red cedar and incense cedar, is a very popular way to side a custom home or to reside an existing home in a makeover.  What makes cedar such a great product is its long-term sustainability in respect to insects and weather.  Wood siding is by far the most popular choice in mountain communities where a “green” look is desired.  As the summer months approach look for cedar prices to start to rise again.
