When you choose Ultrex, you know you are selecting the best material for windows and doors.

Your customers trust in your expertise to select a reliable product for their project. We want to help by sharing valuable information to make the process easier.

Integrity windows and doors are made with Ultrex® fiberglass, a material innovation pioneered and perfected by Marvin®. The patented, co-extruded, acrylic cap takes fiberglass to a new level.

But why should that matter to you? Because its use has created products that are far stronger, maintain a superior painted finish, have greater insulation value, and last longer than other options on the market. This will make your customers more confident in your recommendation and happier in the long run. A win-win.

Far Stronger

Ultrex fiberglass is the strongest material of its kind. In fact, one square inch can support 34,000 lbs. Stress-test results show it’s 8 times stronger than vinyl, and 4 times stronger than vinyl/wood composites.

Superior Painted Finish

Ultrex employs an acrylic finish to provide longer-term color retention. It performs so well that, unlike vinyl, Integrity windows are available in dark colors without fear of increased heat loads, UV degradation, or fading.

Greater Insulation Value

Ultrex expands and contracts at virtually the same rate as glass, so Integrity windows stay tight and true making them resistant to stress crack, leaks, and seal failures that compromise energy efficiency.

Last Longer

Ultrex lasts as much as 38% longer than roll-form aluminium, vinyl, and vinyl/wood composites. It doesn’t leak, corrode, or rot. The Ultrex fiberglass finish is 3 times thicker so it won’t crack, dent, chip, or peel.
