Decisions about siding are consistently among the most difficult for environmentally concerned designers and builders of residential and light commercial buildings. Siding must withstand all types of weather, look attractive, and be affordable to buy and install. Alternatives can include solid wood, APA-rated plywood, Oriental-strand board, wood-resin composites, stucco, fibre-cement, masonite, as well as aluminum. The buyer should research the alternatives completely before making decisions on the purchase.
