Already known for the unparalleled quality and beauty of their windows, Marvin introduced the Integrity brand in response to the needs of builders and architects.
No matter which window you choose, no matter the design, you have the peace of mind of knowing that it will stand up to the elements.
Every Integrity window is made using Marvin’s unique, patented Ultrex pultruded fiberglass.
Stronger than vinyl, fiberglass composites, or aluminum, these windows are designed to stand the tests of time without showing the signs of age or wear.
What are the advantages of Ultrex fiberglass?
Integrity windows made with Ultrex are incredibly tough, with eight times the strength of vinyl. Not only does it stand up to stress; Ultrex resists cracking, fading, peeling, and other evidence of wear and aging that typically appear after years of exposure to sun, wind and rain. This means you can be confident that the integrity window you choose today will look just as beautiful a decade from now.
Integrity Windows Are Energy Efficient
This also means that the energy efficiency of your windows will not fade with time. Seals do not leak and fail, and the comfort of interior environments is not impacted.
Every Integrity window meets or exceeds the standards of the federal government’s ENERGY STAR guidelines.
This means that homeowners will enjoy many years of reduced energy bills, while enjoying windows that are every bit as beautiful as those using wood materials.
