Fiberglass Windows Installed for Homeowners in Milwaukee, WI

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. So, where in Milwaukee, Wisconsin, can you find a great selection of well-made fiberglass windows? Simply look to Siding Unlimited. We’re siding … and a whole lot more! And we have the credentials to prove it.
