This environmentally-safe vinyl compound exceeds all required materials standards for strength and color retention established by the American Architectural Manufacturers’ Association (AAMA).

Window Materials

Material: Vinyl
A strong plastic material that is used for its durability, energy efficiency and ability to stand up to the elements. This material will never fade in color, flake, peel or rot..


Material: Wood
Wood comes from trees that grow in a variety of species, such as fir, pine, mahogany or alder. Each species has a range of characteristics, like grain, color and sap content, which contributes to its unique appearance.


Material: Wood Clad
Like a coat of armor, cladding is a strong layer of metal on wood, providing extra protection and low maintenance benefits with no exterior painting required.


Material: Aluminum
A lightweight and strong material that is a cost effective alternative to wood. This material is corrosion-resistant and performs well in most climates.
