Why Choosing the Right Windows Matters
Window Solutions That Withstand Sun, Snow, and Storms

In the western regions of the U.S. - from the high-altitude sun and snow of Colorado to the dry heat and winter storms of California - extreme weather is part of everyday life. Homes here face a unique combination of environmental challenges, and one of the most important lines of defense? Your windows!
At Mountain States Building Products, we understand the demands of building in these diverse climates. That’s why we partner with trusted manufacturers - like Andersen Windows - to offer high-performance window solutions that are built to withstand the elements without compromising on style or sustainability.
Built for Western Durability
Without the right materials, windows can warp, peel, or crack due to soaring temperatures, UV exposure, and sudden weather shifts. Andersen’s 100 Series windows and doors are engineered to handle it all - whether you're replacing outdated units, remodeling, or building a new home from the ground up.
Crafted from Fibrex®, a composite made of recycled wood and PVC, the 100 Series is twice as strong and features a finish 12x thicker than painted vinyl. Unlike traditional vinyl windows, they won’t melt, bow, or crack - even in temperatures up to 150°F. And their clean lines and matte finishes offer a modern look with minimal maintenance.
Proven in the Field, Trusted by Pros
Custom home builder Greg Gallo of GHG Builders, based in the San Francisco Bay Area, has been using the 100 Series for over eight years.
“I’ve received nothing but positive feedback from clients saying how well the windows hold up in this intense climate,” says Gallo. With a sleek profile and low-visibility seams, the 100 Series fits right into modern West Coast and Mountain West architectural styles. Even seasoned architects are impressed - often mistaking them for high-end wood windows.
Smart, Sustainable, and Cost-Effective
In places like Colorado and California, where eco-conscious design is increasingly important, Fibrex® delivers on both performance and sustainability. The 100 Series offers ENERGY STAR® certified options to help reduce energy costs while minimizing environmental impact. Its superior insulation - nearly 700 x better than aluminum - means your home stays cooler in summer, warmer in winter, and more efficient year-round.
And perhaps best of all? It doesn’t break the budget. “Usually green materials cost more,” Gallo says. “But with the 100 Series, clients actually save money compared to wood - and they’re doing something better for the planet.”
