Marvin Infinity Windows are strong, but are they energy efficient?

We can go on and on about how strong and long-lasting a window is, but in today’s world energy efficiency is just as important. The patented Ultrex material has an extremely low thermal expansion rate, keeping the windows stable and weather tight, reducing the risk of seal failures and air leakage into your home. The Marvin glass options include the standard LoE-272 glazing which will maximize your home’s thermal efficiency, as well as the LoE-366, which is recommended for high sun exposure locations. This means you can take advantage of the already amazing sight lines that Marvin Windows give you but your utility bill doesn’t have to suffer.
