Frequently asked questions

What is the potential increase in span using fiberglass over vinyl?

Fiberglass is approximately 8 to 10 times stronger than vinyl. This enables us to produce very large windows. Typically, most vinyl window configurations are limited to spans less than 7 feet tall. Cascadia has produced windows that span up to 16 feet tall or, when coupled into a strip, many hundreds of feet long. For more information on span limitations, feel free to contact your local Cascadia sales rep.
