Only select Ponderosa pine is used to make the wood parts of our double hung windows. Wood is nature’s best and most beautiful insulator, so you can count on our double hungs to provide excellent thermal performance and great looks. To inhibit water and insect damage, we treat all wood parts with a water-repellent preservative.

Our clad units have a heavy-duty extruded aluminum exterior that requires no painting. We offer seven standard and three decorator colors.

We've made your world easier. Windsor’s double hung and glide-by windows are not only an attractive addition to a home, they are extremely easy to maintain. The sash on the double hung easily tilts in and removes for easy cleaning. Our unique locking shoe balance system also allows you to effortlessly replace or remove individual sashes. Clad units come with heavy-duty .050 extruded aluminum cladding that resists the elements.
