While vinyl is a commonly used window material due to its cost effectiveness and resistance to water, it may not be the best option for making an entire window. This is because vinyl is a flexible material that’s prone to warping, particularly in extreme heat. The problem is magnified with a black vinyl window, because its color absorbs the sun’s heat — a white window would reflect it. Over time, the cycle of expansion and contraction can lead to problems like the seal between the frame and glass breaking.
A better alternative is a window made from Fibrex material. Made from thermoplastic polymer and reclaimed wood fiber, Fibrex material is twice as strong as vinyl and able to withstand temperatures up to 150°F. Its combination of durability and beauty is the reason black Fibrex® material windows are a better idea than black vinyl windows. Fibrex material windows are available through our most economical 100 Series product line .
