Fiberglass windows are a great way to lower your energy costs and keep your home heated or cooled to your desired temperature. Fiberglass is about eight times stronger than vinyl, which means it will be better able to maintain the temperature of your house. Fiberglass doesn’t warp and lasts about 50 years, unlike wood or vinyl which means fewer replacements.
Since quality fiberglass windows are relatively new, it is likely that if your house is more than 15 years old and has not been recently remodeled, you have vinyl or wood windows. Don’t wait to lower your energy costs. Contact a Denver window company and upgrade today.
