New brochure highlights insulating benefits of Intercept ‘Warm-Edge’ spacers by PPGPITTSBURGH, April 4, 2007 –
PPG Industries’ performance glazings business has introduced a brochure for homeowners and window dealers detailing the insulating and energy-saving advantages of windows made using the Intercept
“Warm-Edge” spacer system by PPG.
Spacer System, introduced in 1992, has become one of the window industry’s most trusted systems for insulating glass (I.G.) units. It is now at work on more than 600 million residential windows in North America, surpassing any other insulating spacer system.
The key to the performance of the Intercept
Spacer System is its U-channel design, which functions as a thermal barrier, reducing heat loss through the window and maintaining the structural integrity of the I.G. unit throughout its lifetime.
Under normal weather conditions, I.G. units expand and contract according to temperature changes. In ordinary I.G. units, the sealant that holds components together absorbs the stress of this ongoing expansion and contraction, eventually leading to the failure of the sealant and the loss of the window’s insulating integrity.
With the Intercept
Spacer System, the U-shaped metal spacer expands and contracts instead, enhancing the stability of the sealant and allowing the I.G. unit to maintain its original insulating capabilities.
When used in conjunction with low-emissivity glass from PPG – such as Sungate
60 or Solarban
70XL glasses – I.G. units made with the Intercept
Spacing System can improve the energy efficiency of residential windows by 30 percent or more.
