Designed for warmer climate locations, radiant barrier foil softwood plywood panels for roof construction can help reduce attic temperatures and contribute to lower utility costs. The pre-applied foil wrap on the 4x8 structural panels blocks 97% of radiant heat, the company says, reducing heat gain in the summer and heat loss in the winter. The structural softwood panels are SFI certified; FSC-certified panels are also available. 800.547.9520. www.timberproducts.com
