Summer Energy Savings & Comfort. Low-E insulating glass reduces heat penetration from solar energy.
Get the BarrierXP™ Advantage!
BarrierXP insulating glass packages maximize thermal efficiency and energy savings, while minimizing the damaging
UV rays that cause carpets and furnishings to fade.
- In winter, BarrierXP increases R-Value (resistance to heat flow) by more than 100%
- In summer, BarrierXP reduces solar heat gain by almost 48% to help reduce air-conditioning costs
The Value of Argon Gas
Super-insulating argon gas between the panes of glass counteracts heat/cold conduction. Invisible gas acts a
brake on energy losses for superior thermal performance. Argon gas also helps to reduce noise infiltration.
Look for the NFRC Label
The National Fenestration Rating Council (NFRC) is a non-profit industry organization that is committed to providing accurate,
fair and reliable testing data to help consumers, architects and builders compare the energy performance of window and door
products. The lower the U-Factor, the less money you'll spend heating your home. The lower the Solar Heat Gain
Coefficient (SHGC), the more you'll save on air-conditioning costs.
Winter Energy Savings and Comfort. Low-E insulating glass reduces heat loss by reflecting warm air back
into your home.
Gentek windows are engineered for maximum thermal efficiency. Heavy-duty sash and main frame, multi-layer weatherstripping,
airtight insulating chambers, bulb seal, and the PPG Intercept™ Warm Edge Spacer System help block air infiltration
and reduce heating and cooling costs.
For even greater energy savings, choose our BarrierXP™ insulating glass package. BarrierXP combines Guardian
Acclimate™ RLE (Residential Low-E) glass and argon gas, along with the PPG Intercept Warm Edge Spacer System, to achieve
the ENERGY STAR® rating for energy savings.
ENERGY STAR is a government-backed voluntary partnership program sponsored by the U.S. EPA and the U.S. DOE, which promotes
environmental protection and superior energy efficiency in products, buildings and homes.
An average household spends more than 40% of its annual energy budget on heating and cooling costs. You can save
up to 15% of your total energy bill with ENERGY STAR qualified windows.
