Milgard SunCoat®

SunCoat Low-E is a clear, low-emissivity coating applied to one side of the glass in our dual-pane windows. This microscopically thin coating filters the sun's energy in the summer and reduces heat loss in the winter, making even energy bills look better. Low-E has been a product usually recommended for cold climates. Now with our introduction of SunCoat Low-E glass, you can use this product everywhere, from the heat of Southern Nevada desert to the cold of Chicago and Alaska winters.

You can get even greater thermal performance with the addition of argon gas to our standard, dual-pane, SunCoat Low-E insulating glass. In fact, our vinyl and fiberglass insulated windows have even been recognized by ENERGY STAR® for their exceptional energy-saving qualities in your home.

The Benefits of Milgard SunCoat Low-E Glass Are Clear

• Comes standard on all Milgard windows and doors
• Reduces heat and cooling loads
• Reduces harmful UV rays that fade carpet and furniture up to 78%
• Provides all around comfort, all year long

ENERGY SAVINGS

Windows can account for up to 30% of the annual energy consumed in a home. In the summer, Milgard's SunCoat Low-E keeps your home cool and comfortable by rejecting the sun's heat and damaging rays. In the winter, SunCoat Low-E helps your home stay warm and cozy by blocking heat loss to the cold weather outside.

MILGARD SUNCOAT LOW-E VS. ORDINARY GLASS

Installed in identical test homes in California's central valley, Milgard SunCoat Low-E glass demonstrated a remarkable reduction in energy use compared to ordinary clear glass.

The home featuring Milgard vinyl windows and SunCoat Low-E glass showed a 27% savings in summer cooling costs compared to the home with ordinary clear glass. The average summer afternoon demand for air conditioning in the SunCoat house was 30% lower due to reduced solar heat gain. SunCoat also produced significant savings on winter heating bills.

The test houses were identical single-story, 1,850 square-foot, 3-bedroom production homes. They were located on the same block with identical orientation and solar exposure. About 50% of the glass faced west.

From the standpoint of building design, this test proved that incorporating SunCoat enables the use of more windows and more dramatic views, without compromising on comfort or energy efficiency.
