Low-E2 and Low-E3 Glass Brings Science and Clarity Together

Infinity from Marvin replacement windows are known for their beauty and durability. They’re also known for their high-performance Low-E2 glass. How does Low-E2 glass compare to regular dual-pane glass? Low-E2 glass is layered with 8 microscopic coatings that cut UV transmissions down to 17% with virtually no effect on the clarity or color of the light that enters your home. Regular dual-pane glass lets 63% of UV light into your home.

Marvin’s Low-E2 glass also uses a hermetically-sealed system for optimum insulation from heat, cold and sound. When the windows are constructed, a low-conductivity spacer is used to separate the two panes of glass. The space between the two panes is then filled with an argon gas blend. This gas blend helps minimize thermal transfer.

Marvin’s Low-E2 glass is 56% more energy-efficient in the summertime and 45% more efficient in the winter compared to regular dual-pane glass. Marvin’s Low-E3 SmartSun glass is even better. It is up to 70% more energy efficient in the summer and 45% more energy efficient in the winter than regular dual pane glass. This glass also blocks 95% of harmful UV rays.

Summer sun is filtered and reflected back outdoors with Low-E2 glass. In the winter, indoor heat is reflected back into the home thanks to Low-E2.

Glazing Options

We know how important energy efficiency is, and Marvin’s standard LoE2-272® glazings are a simple means of maximizing your home’s thermal efficiency. LoE2-272 reflects heat back to its source so summer heat is reflected outdoors and winter indoor heating is retained. At the same time; up to 84% of the sun’s UV rays are screened to reduce fading and damage to upholstery and carpets. Argon gas and warm edge spacers are also standard features.

The Power of Ultrex®

Lastly, Marvin’s Ultrex® fiberglass is far less thermally conductive than aluminum (500 X less!) and insulates much like wood. This means that Ultrex® provides an insulated barrier against extreme weather temperatures, keeping your home comfortable, and helping to reduce heating and cooling costs.

Energy Star® and the NFRC

Infinity from Marvin® windows exceed the performance requirements for energy reduction set down by the U.S. Department of Energy and the U.S. Environmental Protection Agency in their Energy Star ratings. And, Infinity qualifies for the Energy Star rating in all U.S. climate regions.

Finally, the not-for-profit National Fenestration Rating Council sets standards for the window and door industry. Infinity earned one of the highest possible ratings for energy performance. The ratings measure light transmission and heat loss or gain under varying conditions.

Right now is the best time to purchase Infinity from Marvin replacement windows for your home. The American Recovery and Reinvestment Act of 2009 provides federal tax credits for certain building components that improve energy efficiency. This includes energy-efficient replacement windows. These building components have to be installed between 2009 and 2010 in order for you to be eligible for the tax credit. Many Infinity from Marvin windows actually qualify for the tax credit.
