Windows Materials

Window frames are available in a variety of materials including aluminum, wood, vinyl, and fiberglass. Frames may be primarily composed of one material, or they may contain a combination of different materials such as wood and vinyl. Multiple parameters of each window frame material presented in the comparative table below:

* Vinyl and fiberglass frames perform well in accelerated weathering tests. Because vinyl is not as strong as other materials, some vinyl frames are reinforced with metal or composite materials to improve their structural strength.

** Modern aluminium window frames are typically separated by a thermal break made of a polyamide. This greatly increases thermal resistance, while retaining virtually all of the structural strength.

Composites may combine materials to obtain aesthetics of one material with the functional benefits of another.
There is a wide variety of brands and styles as well as wide range of options available in the market.
