Ultrex Advantages

Strong, stable, durable and virtually indestructible, Ultrex is possibly the perfect building material, creating windows and doors that leave other materials in the dust. Made from pultruded fiberglass, Ultrex outperforms vinyl and roll-form aluminum on nearly every measure.

No Other Window Material
Matches Up to Ultrex

  • 8x stronger than vinyl
  • 9x less heat expansion and
    contraction than vinyl
  • Non-conductive and
    non-corrosive
  • Patented finishing process resists
    fading and cracking
  • 10/20 warranty (10-year manufacturing
    warranty/ 20-year glass seal warranty)

Bottom Line: Integrity windows and doors are the most maintenance-free, hassle-free, worry-free on the market.

The Strength of Steel

Ultrex is as strong as steel and eight times stronger than vinyl. In fact, it’s so tough, we have to use diamond-edge blades just to cut it to size. It kind of makes hail, wind and even baseballs seem like child’s play.

Patented Performance

The strength of Ultrex comes from our patented fiberglass pultrusion process.

What starts as strands of glass (A) finishes as the strongest window material on the market (B). Lightweight and strong as steel, that’s the patented performance of Ultrex performance you’ll be enjoying for a very long time.

Lack of Flexibility is Our Strong Suit

The rigid structure of Ultrex ensures a true and perfect fit that lasts. Even after years of use, Integrity windows will continue to slide, crank, raise and lower as if they were installed yesterday.

833% less expansion than vinyl

Expansion Graph

Why Care About Thermal Expansion?

The more a material expands and contracts, the more susceptible it is to failures such as:

  • – Distortion
  • – Streaking
  • – Cracking
  • – Warping

Because it is more resistant to thermal expansion, Ultrex has fewer problems and virtually no maintenance required.

Ultrex matches the expansion rate of glass to maintain
a tight seal for efficiency.

Integrity vs. Vinyl

A more rigid foundation allows for thinner framework and a more attractive appearance.

What You See is What You’ll
Continue to Get

Our patented finishing process outlasts the competition, resisting fading that can plague other composite materials. Our thick acrylic finish bonds directly to the surface to prevent dings, mars and scratches.

Our patented, mechanically bonded finish is up to 3x thicker than competitive finishes.

Excellent UV resistance allows Integrity
to offer rich, dark finishes.

The Ultrex patented coating system is AAMA 623-10 certified and is listed on the exclusive AAMA Verified Components List for 623-10, 624-10 and 625-10 — a claim the competitors can't match. See more about what makes Integrity Best in Class.
