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 Andersen’s 100 Series windows and doors are engineered to handle it all - whether you're replacing outdated units, remodeling, or building a new home from the ground up.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.”

Building or remodeling along Colorado's Front Range or in the Rocky Mountains requires materials engineered for high altitudes and extreme weather. Windows and doors define modern mountain architecture while serving as the primary thermal envelope between your living space and harsh Alpine elements. Architects, custom home builders, and homeowners choose the Weather Shield Contemporary Collection to combine modern design with thermal performance. As a premier Colorado distributor of Weather Shield products, Mountain States Building Products supplies these high-performance window and door systems across the Front Range and Rocky Mountain regions. Features of the Weather Shield Contemporary Collection Weather Shield designs windows and patio doors that blend high-end design with structural integrity. The Contemporary Collection offers specific engineering features optimized for modern mountain homes. Minimalist Profiles and Maximized Glass The Contemporary Collection features narrow sightlines and maximum glass area. These slim aluminum-clad profiles maximize natural light and maintain unobstructed views of the Front Range and surrounding mountain landscapes. Multi-Panel Door Systems and Floor-to-Ceiling Glass Large-format direct-set windows and multi-panel sliding or stacking door systems support seamless indoor-outdoor living. These systems allow builders to create expansive glass walls that open interior spaces to exterior decks and outdoor living areas. Durable Aluminum-Clad Exteriors and Wood Interiors Featuring warm wood interiors paired with low maintenance extruded aluminum exterior cladding, these units resist intense high-altitude UV radiation, heavy snow loads, and moisture. Custom exterior anodized and powder-coated finishes allow precise architectural matching for modern or mountain-modern builds. High-Altitude Energy Efficiency and Thermal Performance Colorado high-country homes experience extreme temperature swings, intense daytime solar gain, and high wind loads. Weather Shield windows feature low-E glass coatings, warm-edge spacer systems, and multi-layer weatherstripping to meet strict local energy codes, reduce HVAC loads, and increase year-round comfort. Custom Sizing and Hardware Options Every custom home build requires unique specifications. The collection includes custom frame dimensions, specialized grille patterns, and contemporary hardware finishes to meet exact architectural plans. High-Altitude Building Performance Standards Installing windows and doors in high-altitude environments requires attention to climate-specific variables. To withstand high UV exposure and resist fading, frames utilize heavy-duty extruded aluminum cladding. To handle severe temperature extremes, advanced thermal separation is achieved through multi-chambered frames and integrated thermal breaks. Additionally, high-altitude pressure equalization is managed using specialized capillary tubes within the insulated glass, while heavy-duty frame construction provides high DP-rated structural load resistance against severe snow and wind forces. Local Supply and Support Across Colorado Sourcing structural building materials for mountain job sites involves specific logistical considerations. Lead times, regional building code compliance, and high-altitude glass specifications require specialized local knowledge. Mountain States Building Products acts as a regional supplier for builders, general contractors, and homeowners in: The Front Range: Denver , Boulder, and surrounding foothill communities. Mountain Communities: Summit County, Grand County, and surrounding high-country areas. Our team assists with product selection, technical specifications, and local order coordination for high-altitude residential construction and renovation projects.
