New Southern Pine standards take effect in June
Effective June 1, 2012, the Southern Pine Inspection Bureau (SPIB) has issued some new design values for Southern Pine Lumber. The changes will affect only visually graded Southern Pine and Mixed Southern Pine sized 2” to 4” wide and 2” to 4” thick (2x2s through 4x4s) in No.2 and lower grades (No.2, No.3, stud, construction, standard and utility). This also includes new design values for No.2 dense and No.2 nondense Southern Pine. Design values for all other grades and sizes of visually graded Southern Pine remain the same, pending results of testing scheduled for completion later this year.
The last major change for visually graded dimension lumber occurred in 1991 when design values for Southern Pine and other North American species were published based on In-Grade testing of full-size samples of commercially produced lumber. Since 1994, SPIB has conducted an annual resource-monitoring program developed in collaboration with the U.S. Forest Products Laboratory (FPL). SPIB is the first rules-writing agency to publish new design values. Rules-writing agencies responsible for other species are in different stages for evaluating design values.
Design values for structural lumber undergo a rigorous approval process. SPIB partnered with Timber Products Inspection to sample No.2 2×4 test specimens according to a plan approved by the American Lumber Standard Committee (ALSC) Board of Review. SPIB and Timber Products conducted destructive tests in bending and tension, plus gathered stiffness and property data, all in accordance with ASTM International standards. Throughout the process, technical review was performed by FPL. The ALSC Board of Review approved the new design values early in 2012 with a recommended effective date of June 1, 2012.
As June 1 approaches, users should begin using the new design values and revised span tables if they haven’t done so already. The intent of the six-month transition period was to minimize project delays and supply chain disruptions by providing time to begin to use the new design values or switch to other Southern Pine grades or sizes meeting performance requirements. Southern Pine users have many available product options, including visually graded dimension lumber and an increasing supply of mechanically graded lumber. Many producers and key customer groups have already successfully transitioned to the new design values with minimal disruption to their businesses.
Building codes reference design values are certified by the ALSC Board of Review. The American Wood Council (AWC) publishes these design values in a supplement to the code-referenced National Design Specification (NDS) for Wood Construction. Building codes also include span tables and other prescriptive requirements that will need to be amended to reflect the new design values. Visit AWC.org to download the AWC Addendum to Design Values for Wood Construction, revised prescriptive span tables and other updates to AWC’s standards and design tools. Also visit Southernpine.com to obtain easy-to-use span tables for specific grades and sizes of Southern Pine lumber.
SPIB and timber products are currently working to complete the full In-Grade matrix by destructively testing No. 2 select structural 2x4s, 2x8s and 2x10s in bending, tension and compression. Additional design value changes are expected once all the testing is completed later this year. Moving forward, Southern Pine will continue to be monitored with annual destructive testing.
Weyerhaeuser is offering OSB rebates
Forest products supplier Weyerhaeuser has announced a mail-in rebate program for building industry professionals this summer on several of its oriented strand board (OSB) products. The company is offering $3.00 cash back per panel of 7/8-in. or thicker of Weyerhaeuser Edge Gold flooring (or $1.50 for each 23/32-in. panel), and $1.00 per panel of Weyerhaeuser Radiant Barrier Sheathing (RBS) — up to 100 panels for each product line. Building material dealers also can earn rebates of $0.25 per panel, up to $250 total for Edge Gold flooring and up to $100 total for RBS.
Purchases made from May 1 to Sept. 30, 2012, by users who have not purchased the products in the last 6 months, are eligible. More details on the rebate promotions are available at woodbywy.com/Gold for the flooring program and woodbywy.com/Silver for the RBS program.
Weyerhaeuser Edge Gold flooring panels feature Down Pore self-draining technology to drain water off of floors during construction, which helps eliminate potential damage and reduces delays in construction. Weyerhaeuser provides a 200-day no-sand guarantee against edge swell, and a limited 50-year structural warranty against panel delamination.
Weyerhaeuser RBS panels are foil-laminated to help lower home energy use by reflecting up to 97% of the sun’s radiant energy and reducing heat build up in attics, which helps lower energy bills.
To help provide customers with continuing reliable supply of both flooring and roofing OSB panels, Weyerhaeuser OSB is expanding product lines at two mills this summer.
Beacon Roofing announces acquisition
Beacon Roofing Supply has reached an agreement to acquire Cassady Pierce Co., a distributor of residential and commercial roofing products, for an undisclosed sum. Founded in 1947, Cassady Pierce has six locations in the Pittsburgh area and annual sales of approximately $52 million. Closing on the transaction is expected on May 31, 2012.
“Cassady Pierce is an industry leader in Western Pennsylvania and allows Beacon to expand our presence in that very important market beyond our existing North Coast Pittsburgh branch,” said Paul Isabella, Beacon’s president and CEO.
