Vinyl frames get brittle in the cold. Cheap fiberglass warps under a heat cycle. We've spent almost 30 years watching what actually fails on Wisconsin homes, which is exactly why we partnered with Marvin instead of a cheaper alternative; their Ultrex frames are built for this exact swing between -20° winters and humid summers.

Yes. We hold Diamond Level Partner status with Infinity by Marvin — one of the highest dealer tiers — so you're working directly with a certified installer, not a reseller.
The core difference is Ultrex® fiberglass. It's roughly 8x stronger than vinyl and holds its shape through temperature swings that cause vinyl to warp or crack over time — which matters a lot in Wisconsin.
