Royal Group backs its vinyl Haven Insulated Siding with up to 11/8 inches of fire-retardant foam that matches the thermal expansion of the siding to prevent cracking, breaking, and distortion. The double 6-inch profile imitates cedar clapboard and comes in 14 colors. Backed by a lifetime warranty, the company says its impact- and termite-resistant siding reduces noise up to 45% and will not rot, crumble, peel, scratch, split, or warp. 800.488.5245.
