Ply Gem’s new line of cellular PVC trim and molding is ideal for creating weather-resistant architectural detail for residential exteriors and provides a low-maintenance alternative to traditional wood trim. The cellular PVC pieces are resistant to cracking and warping, and the cut edges don’t need to be sealed or caulked. Ply Gem. 888-975-9436. www.plygem.com. Booth No. C3819.
