What is a clad-wood window? What is a clad-wood door?
A clad-wood window or clad-wood door is one that’s made of wood with a protective material covering it on the exterior. All our wood window and door products are clad. The exterior materials we use as claddings are low maintenance and never need repainting. Perma-Shield® cladding, extruded aluminum, and fiberglass composite are the materials we use. Each of these cladding materials offers unique benefits, but all are durable and aesthetically pleasing. They offer the opportunity for beautiful and insulating wood interiors without extra exterior maintenance.

How does wood compare to other materials?
Which type of cladding is best?
While the cladding material matters, it’s important to remember that it doesn’t exist in isolation. How and where the cladding is applied, or, in other words, how the window is designed, is just as important. When materials and design are combined well like in our products, they support the performance and aesthetics of the finished product and help to improve longevity. We know how to put the right materials in the right places to make quality clad-wood windows and doors — we pioneered the process more than 50 years ago.
Using a variety of cladding materials helps us offer product lines that meet various price points without sacrificing quality. Here’s a side-by-side comparison of our clad-wood options so you can see how price shifts with the offerings available.
