Fiberglass window choices for new build in Colorado
We are building a new home in Colorado, 7100 ft, south facing, energy efficient, single story. That is the short story. We are only considering fiberglass windows. The choices are Alpen 525, Marvin Integrity, Miguard Ultra and new to list Kolbe Forgent. In terms of energy efficiency: U, SHGC, VT the best is Alpen, made just outside of Denver, but no local vendor. The rest have local vendors for support.
My question is two fold, has anyone feedback on any of these windows? And what do you think of the newly release Kolbe? The Kolbe price is sweet but the product is NEW,,which makes me hesitant
Comments all welcome. Lydia
