Aluminum trim coil is ideal for wrapping your home’s exterior trim surfaces such as window and door casings, porch posts, the drip edge and fascia. Ply Gem’s trim coil creates a clean, sharp finish that holds up to harsh weather. It can be field formed into virtually any shape. The tough Environ® two-coat, baked-on acrylic coating gives Ply Gem’s trim coil a smooth finish while a durable thermoplastic PVC coating creates a textured woodgrain look.
