Superior Finishes

Infinity uses a patented, mechanically-bonded finish that is up to 3x thicker than competitive finishes. It provides superior resistance to scratching and UV degradation, even on darker colors. The finishes ensure long-term color retention and durability. This is compared to competitor’s thin painted finish that can expose the rough fiberglass material.

The Ultrex coating system is AAMA 623-10 certified, meaning our commercial grade finish resists the harshest weather conditions mother nature offers; a claim competitors can’t match.

Beautiful Details

Created for strength and beauty, Infinity windows arrive with clean mechanically-bonded corners, traditional details, and narrow profiles to maximize your view. Vinyl windows can arrive with messy welded corners and bulky profiles that reduce your view.

Tough, beautiful windows made of Ultrex Fiberglass outlast the competition.
