WINDOWS THAT HANDLE THE WEATHER
Some decisions should only be made once. That’s why our windows are built for life and our projects are done right the first time. Beauty, function, and fit are all provided with our Lifetime guarantee. Infinity Windows outperform vinyl by 8X and Fibrex by 3X. Choose a Classic or Contemporary design and the enjoy peace of mind that your windows won’t melt or warp in the Colorado heat. They won’t chalk or fade. Welcome to clear views, cool rooms, and enjoying more daylight like never before!
Lifetime Windows & Siding uses Ultrex fiberglass because the material you choose for your windows matters. Because Ultrex is so strong, we actually use less of it in Infinity window frames. That means you get more daylight and greater views outside coming through your window.
