BEAUTY IS IN THE DETAILS. Ply Gem Trim and Mouldings offer the beauty of wood without the maintenance. Cellular PVC does not contain or absorb water, so it won’t rot, warp or split. If you choose to paint it, Ply Gem Trim and Mouldings hold paint much better than wood and also won't attract insects. It’s no wonder more and more homeowners are choosing this new and improved technology to enhance their home’s curb appeal. Ply Gem Trim and Mouldings not only last longer than traditional accent, window and door trim products, but offer a wide range of design features and versatility that takes a home from simple to stand out. It's good looks that last.
