APA has updated the Technical Note: Controlling Decay in Wood Construction, Form R495. This publication provides an overview of preventing and minimizing the degradation of wood through proper design, storage, construction and maintenance details.
APA recently released a new Technical Note that provides specification and installation recommendations for panel subfloors to be used under hardwood flooring.
Engineered wood is the building material that flexes with your imagination offering a wide range of options for nearly any building type. This webinar will discuss the innovative use of glulam in a spectacular cathedral in Oakland, California and a wood-framed elementary school in Texas that exceeded all expectations for economy and aesthetics.
The construction experts at APA and WoodWorks offer this free online course which qualifies for a one-hour HSW credit through AIA and AIBD.
APA has updated two publications pertaining to glued laminated timber (glulam) design specifications and layup combinations.
APA recently released a new Technical Note entitled, Technical Note: Temporary Construction Loads Over I-joist Roofs and Floors, Form J735. This new technical note provides recommendations for proper placement of heavy loads in a partially completed light-framed structure to prevent damage to the structure and/or injury to the work crew.
The APA Publications Index, Form B300 NN, has been updated. The revised 2008 index provides a complete listing of APA design and construction guides, product guides, builder tips, case histories, industrial publications and other materials available from the Association.
Question: Plans call for five- ply plywood roof sheathing but the lumber yard sent out four-ply. They say they won’t have five-ply in stock until next month. What is the difference between the panels?
Question: I specified 1/2-inch roof sheathing for a commercial building. When I was inspecting the project I found that the contractor had installed 15/32-inch. What can be done to correct the situation?
Answer: A wood structural panel that is 15/32 inch thick contains six percent less wood fiber than a 1/2-inch thick panel. The effect on structural properties and characteristics is negligible. In most applications, the 1/32 of an inch difference in thickness of span-rated wood structural panels does not affect performance. In fact, assuring adequate performance in specific applications is at the heart of APA’s rigorous program of quality auditing and testing.
Question: What approved methods of weatherization exist for I-joists that are extended for soffit and eave locations on a roof structure? Do you need to have an enclosed soffit and eave, or can they be painted?
