Nowadays, with so many types of replacement windows available, why are fiberglass windows a consistently popular option? For homeowners, the reasons are abundantly clear—strength, durability, thermal performance, and cost efficiency. With a heat conductivity that is 800 times less than aluminum, fiberglass makes for one of the strongest frame materials. It can withstand the most severe weather conditions without warping, rotting, or rusting. Fiberglass also has a low thermal expansion, so it won’t expand and contract as much as other frame materials might, which prolongs the life of the windows and maximizes performance long term.
