 | The Intercept warm-edge spacer system is an important part of an efficient window. The unique, tin-plated steel, U-channel design creates an effective thermal barrier to help reduce conducted heat loss through the window. Typically the edge of the glass is the least efficient area of a window. Unlike ordinary spacers, Intercept spacers insulate the edge of the glass to keep that part of the window warmer and make it more energy efficient. |
| Under normal weather conditions, glass units expand and contract with temperature changes. In conventional insulating glass units, sealant (the material that holds the unit together) takes the stress of the flexing. This can cause seal failure and insulating gas loss. In an Intercept glass unit, the spacer flexes instead of the sealant, so it resists spacer movement and premature sealant failure. | |||||||||||||||||
