Why Ultrex Fiberglass Replacement Windows?

The best in replacement windows - Infinity from Marvin

Infinity® replacement windows and doors are made from Ultrex fiberglass - a pultruded fiberglass material so strong and durable it is superior to other window materials. Best of all, it makes Infinity products virtually maintenance free."

Created for strength and beauty

Our patented process starts with strong cables of glass that are saturated with specially compounded resins that are pulled through a heated die and cut with diamond-edge blades. Ultrex goes from forming and curing all the way to the cutting stage. All of these steps create a remarkably durable material that outlasts and outperforms other window materials.
