The Real Argument for Infinity From Marvin Fiberglass Windows McKinney Homes
McKinney, TX is known for hot, humid summers, intense spring thunderstorms with strong winds and damaging hail. You’ll need some tough windows to stand up to and defend against damages, leaks, wood rot and termites.
So Why Fiberglass Windows?

- Fiberglass is Strong: Especially the way Infinity from Marvin makes it. They have a manufacturing process called Pultration. Pultrated fiberglass is not just layers of fiberglass matt smothered in resin! Infinity fiberglass with the trade name of Ultrex®️ takes strands of fiberglass combined with resin and extrudes (pultrudes) it into the shapes needed to make window frames. Infinity’s Ultrex®️ allows us to install larger windows due to its structural tensile strength. Ultrex is 8 times stronger than vinyl and 3 times stronger than the other leading fiberglass window brand.
- No Warping or Shrinking: Unlike vinyl, Ultrex®️ has near zero thermal expansion. In fact, 87% more resistant to shrinking and warping than vinyl. This means no drafts or leaks over time. Expansion and contraction is actually at the same rate as the glass itself. It’s also so heat resistant, it can handle temperatures up to 285 degrees without affecting performance. Vinyl would melt. Thankfully, 285 degrees has never been recorded in McKinney!
- Super Durable Finish: Some brands paint or use a thin gel coat for their finish. These can chalk, chip, and fade over time. Ultrex®️ from Infinity finishes their window frames in a patented acrylic finish that is mechanically bonded to the fiberglass during the manufacturing process. It’s 3 times thicker than other finishes. As far as UV (ultra-violet) protection is concerned, Ultrex’s acrylic finish can withstand 48,000 hours of exposure to intense direct sunlight and still have no evidence of fading.
