CASEMENT ENERGY SAVING BENEFITS

GET THE BARRIERXP® ADVANTAGE!

Upgrade your windows with the BarrierXP insulating glass package† to maximize thermalefficiency and energy savings, while minimizing the damaging UV rays that cause carpets and furnishings to fade. BarrierXP combines multi- layer low-emissivity (Low-E) glass and argon gas, along with the PPG Intercept Warm Edge Spacer System, to achieve the ENERGY STAR® rating for energy savings.

  • 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

†Optional glass packages include BarrierXP 2 and BarrierXP Plus for additional energy savings.

ADVANCED ENERGY SAVINGS

With the rising cost of fuel, energy efficiency is a key consideration when choosing the best window for your home. Thermally engineered for year-round energy savings, Lone Star Windows combine insulating air chambers, the PPG Intercept® Warm Edge Spacer System, multi-layer weatherstripping and a compression bulb seal to help prevent air infiltration and reduce heating and cooling costs.

HIGH-PERFORMANCE GLASS

You might think of glass as being fragile, yet it is one of the most powerful elements in achieving maximum thermal efficiency. Windows are 80% glass, so it’s important to choose a glass package that will protect your home from absorbing outside heat in the summer and losing indoor heat during the winter.

An exceptionally strong barrier, Revere windows by Lone Star are built standard with a 7/8″ insulating glass unit with double-strength glass. For even greater energy savings, choose optional Low-E insulating glass. Low-E features a virtually clear, metallic coating that acts as a thermal mirror to help keep solar heat out during the summer and warm air in during the winter.
