Not only are our Fibrex frames 2 times stronger than vinyl and don’t expand and contract with changes in temperature like vinyl does, but now we have proof that their more durable too. Check out this video of our recent durability test where we removed 10 windows that had been used in a customer’s home for 20 years and then subjected them to a number of on-site and laboratory tests. The results: the windows were as easy to operate and strong as when they were installed with no cracking, peeling or chipping in the frames.
