“Warm Edge” spacer technology is designed to reduce the potential for conduction of cold air from the outdoors, through the traditional metal spacers, to the glass pane. This conduction of cold air not only reduces the efficiency of your energy use, but also creates the conditions for condensation around the glass edges, and the water damage to trim, paint, woodwork and window treatments that condensation can cause.
Alside’s warm edge spacer systems are provided as an energy-efficient alternative as part of the ClimaTech® and ClimaTech Plus ®Insulated Glass Packages.
ClimaTech with PPG’s Intercept™ Spacer System
The Intercept Spacer System is a warm edge spacer featuring a unique, one-piece metal alloy with a U-Channel design that creates an effective thermal barrier to help reduce conducted heat loss through the window. The sealed, one-piece design makes Intercept spacer stronger and better at retaining insulating gas than many conventional designs.
ClimaTech Plus with Edgetech’s SST® Spacer System
The SST Spacer System features a non-metal design that eliminates cool-edge metal-to-glass construction at the glass edge. This ensures greater insulation at the glass edge – where the window traditionally insulates least effectively – and virtually eliminates condensation at the edges of the window associated with metal spacers that conduct cold air.
The SST Spacer System combines a patented structural foam spacer with a seal of hot metal butyl to create a non-conductive edge. The elimination of metal-to-glass contact makes the ClimaTech Plus glass package up to 54% more energy-efficient than ordinary insulated glass units. The non-metal edge also helps prevent seal failure by minimizing the subtle movement of glass panes within the unit.
