Perfomance GlassenergySMART® family of high performance glass
Here's what you'll find in all energySMART insulated glass units:
During summer, it stays cooler. This means energy savings whether
heating or cooling, and less condensation too!
U-Factor:
measures how well a product prevents heat from escaping a home or building. U-Factor ratings generally fall between 0.20 and 1.20. The lower the U-Factor, the better a product is at keeping heat in. U-Factor is particularly important in northern climates. This label displays U-Factor in U.S. units. Labels on products sold in markets outside the U.S. may display U-Factor in metric units.
Solar Heat Gain Coefficient (SHGC):
measures how well a product blocks heat from the sun. SHGC is expressed as a number between 0 and 1. The lower the SHGC, the better a product is at blocking unwanted heat gain. SHGC is particularly important is southern climates.
Visible Transmission (VT):
measures how much light comes through a product. VT is expressed as a number between 0 and 1. The higher the VT, the higher the potential for daylighting.
UV:
a measurement showing how much of the harmful "fading" UV rays
of the sun is blocked out.
R-Value:
The commonly used measurement which determines the resistance of a
material to heat flow. The higher the R-Value, the better it performs.
Here's what you'll find in all energySMART insulated glass units:
- Either two or three panes of glass
- Patented treated steel U-shaped spacer
- Soft coat Low-E or Low-E "Stacked" (Multiple Layer Coating) (optional) Permits only certain light waves to pass through for energy savings. Unlike most hard-coat glass, our soft-coat has virtually no tint or haze.
- Argon or optional krypton gas filling to better insulate low-E units
- Sealant (bonds the glass to spacer)
- Desiccant (removes moisture from atmosphere between panes)
