  • 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.

  • The NLBMDA Outlook

     

1. IS THE TAIL WAGGING THE DOG? - Op/Ed by Valerir R. Hansen, LBMI Trustee

Today our industry is experiencing the most significant housing downturn in at least a generation. We’re also at the threshold of a new era in American home building, one that will spin off new construction methods, new materials, and require a new attention to process – or a return of old-fashioned craftsmanship. It’s time for lumber dealers, truss manufacturers, and the ALSC to take the leadership in establishing an eco-standard for dimensional lumber. CLICK HERE FOR REST OF ARTICLE

2. LBMI Formal Request to the ALSC 

The Lumber and Building Materials Institute (LBMI), the research and education foundation of the NLBMDA, and the LBMI Green Building Council, respectfully request the American Lumber Standards Committee (ALSC) to adopt a new eco-forest management standard, accredit agencies to certify the standard, and establish a corresponding eco-label (grade stamp).

Cedar Grades And Uses

TIMBER PRODUCTS | GRADES

Clear Grades
Clear cedar has a limited number of natural characteristics and is specified when appearance of the highest quality is desired. Clear grades of timbers are normally supplied green (unseasoned). When required, seasoning is achieved by air-drying.

Knotty Grades
Knotty cedar presents a more rustic appearance and is typically supplied green (unseasoned) in the appearance and structural grades. When required, seasoning is achieved by air-drying except for grades of Light Framing and Structural Joists and Planks which are available kiln-dried.

Surface Textures
Saw Textured The saw textured surface, obtained during the milling process which uses either circular or band saws, is present on all four sides.

Rougher Headed The lumber receives its texture from a milling process which uses roughened planer knives. The rough texture is clearly visible on all four sides.

Surfaced Four Sides (S4S) The smooth surface on all four sides presents a uniformly sized product with a high quality appearance. Sizes from 2×4 (51mm x 102mm) up to 6×6 in. (152mm x 152mm) are generally available. Larger sizes are produced on special orders.

Grade
Description
No. 2 and Better Clear


This grade should be specified when the finest quality rough lumber is desired. The lumber is sound and well manufactured. Its natural characteristics do not detract from the woods fine appearance.

Grading Rule Paragraph
Export R List 401
D and Better Clear
This grade consists of D Clear, C Clear, and B Clear.

The C and Better Clear grade offers good appearance in high quality, well manufactured lumber. Suitable for high quality landscape structures and as exposed posts and beams in heavy timber construction. WRCEA members produce this grade without cut-outs. In most cases, this grade is sold with a specified allowance of D grade.

D Clear grade permits larger and more numerous natural characteristics which are widely accepted in the construction of outdoor structures. Some pieces of D Clear may require trimming to yield clear lengths for the intended use. Available surfaced or rough textured.

Appearance Knotty
A non structural product manufactured to meet the appearance requirements of quality projects. This material has highly restricted wane allowances to give well defined corners. Contains no holes or other characteristics. Represents good value for appearance end uses. Available rough sawn or rougher headed in nominal 2″ (51mm) and thicker sizes.

Group buys up Forest Land

Group buys forest to log, shield it from development
By Tim Reiterman
June 15, 2007

With 100% financing from the Bank of America, a nonprofit conservation group has purchased 50,000 acres of redwood forest along the Mendocino County coast north of Fort Bragg for $65 million and plans to use it for commercial timber harvesting while shielding the land from development.

“We know that this property without protection would have been subdivided into smaller parcels,” Art Harwood, a sawmill operator and president of the Redwood Forest Foundation, told reporters Thursday in the redwood grove outside the Transamerica Pyramid in San Francisco. “Every year in the U.S., millions of acres of forest are bought and sold, and the pressure is particularly high in Northern California.”

Bank and foundation officials said the deal is the first of its kind that relies entirely on private financing.

However, much of the debt is to be paid through the sale of a conservation easement to another nonprofit group that plans to seek state funding.

Harwood said the land, acquired from Hawthorne Timber Co., was heavily logged in the 1980s and ’90s and now consists primarily of second-growth redwood and Douglas fir. “There are a few old-growth trees scattered out there, but we will not be cutting them,” he said.

Foundation officials said they plan to do very little logging at first, and never on more than 3% of the property a year to ensure a long-term supply of jobs and timber. The Redwood Forest Foundation, which is dedicated to restoring working forests, plans to use logging revenue to help pay off the 20-year loan.

The foundation, based in the southern Mendocino County town of Gualala, intends to sell the conservation easement to the Conservation Fund, which plans to use state money approved by voters last year in Proposition 84, the clean water, parks and coastal bond measure.

“We haven’t negotiated the cost of the easement and the terms,” said Chris Kelly, who manages California operations for the fund. “But our intention is to have an agreement allowing no subdivision, development or conversion to non-forest uses, and possibly there will be a cap on harvesting.”

The land is north of Fort Bragg and about 50 miles north of two other parcels purchased recently by the Conservation Fund.
