Fiberglass Windows
Fiberglass window frames are strong, maintenance free and beautiful. And the best fiberglass windows on the market are Infinity Windows by Marvin. They are made from Ultrex, a pultruded fiberglass material developed exclusively by Marvin Windows. For windows in Raleigh, this material is perfect – it mimics the look of beautiful wood, is 8 times stronger than vinyl, and requires virtually no maintenance.
