You get a carefree fiberglass exterior, plus the beauty of a wood interior. And we do mean beauty. Our windows feature furniture-grade, clear, vertical-grain Douglas fir. Without a nail hole or staple on them. What's more, since we use solid stainless steel screws throughout, there's nothing to corrode or rust. Ever.

You can stain our wood interiors clear or finish them to match existing woodwork in everything from a maple to a cherry appearance. For the exterior, you can order Milgard WoodClad windows in seven baked-on standard exterior colors. A wide selection of hardware and grid options is available.
