Integrity windows from Marvin are made with Ultrex®, a patented pultruded fiberglass that outperforms and outlasts vinyl, roll-form aluminum and other fiberglass composites. Integrity Wood Ultrex windows combine an authentic wood interior with a virtually indestructible fiberglass exterior. The All Ultrex Series is made with Ultrex fiberglass inside and out for maximum durability and quality. All Integrity products are built to last and to withstand little fingers, curious pets and even an impromptu game of living room football – all without sacrificing aesthetics.
Ultrex gives homeowners windows that are…
- Low Maintenance – Ultrex performs beautifully for years to come, with a finish that requires virtually no maintenance.
- Energy Efficient – Ultrex’s minimal thermal conductivity serves as a built-in insulated barrier against the elements – reducing heating and cooling costs.
- ENERGY STAR® certified – The Energy Department estimates that by installing ENERGY STAR-rated products, the average U.S. household can reduce its annual energy bill by 15 percent.
- Environmentally Friendly – Ultrex takes less energy to create – about 80 percent less than aluminum and about 40 percent less than vinyl. Also, it’s made mostly of glass, which is made from sand and gravel – a plentiful resource.
- Beautifully Designed – Made by wood window experts at Marvin, Integrity features traditional profiles and details that are more attractive than the “flat” appearance of other materials. Ultrex ensures it will stay beautiful for years to come.
