Clear explanations to help you understand how we work and what to expect.

What is the primary advantage of a fiberglass curtain wall over traditional aluminum?

The most significant technical advantage is thermal conductivity. Fiberglass is approximately 500 times less conductive than aluminum. In the extreme climate of Ontario and Eastern Canada, an aluminum frame acts as a thermal bridge, pulling heat out of the building. Because the VisionPlus® fiberglass frame is a natural insulator, the frame itself acts as a massive thermal barrier, drastically improving energy efficiency and lowering operational costs.
