Exquisiteness keeps up with age when it comes to Integrity windows. Ultrex delivers a grander, consistent finish that can be painted, even in darker colors, without annulling the warranty. No-worry durability was top of mind when Integrity industrialized the patented, high-performance coating method that lets all its products appear as good on the outside as they are tough on the inside.

Long Lasting. Good Looking.

Ultrex is quite possibly the perfect building material for windows and doors. It’s tough, resilient, stable, easy to maintain and resourceful. Integrity windows and doors made with Ultrex pultruded fiberglass out perform roll-form aluminum, vinyl, and vinyl/wood composites in nearly every measurable category. While other windows might bend, break, or crack over a period of time, Integrity windows hold strong and perform under countless stress without showing age or wear and tear.
