The Warm Edge — Insulated Glass For Windows
Intercept™ spacers are so energy efficient that they keep the edges of the glass warmer, dramatically reducing condensation while keeping the cold air out and the warm air inside the home. This unique spacer is just another reason why our windows and doors are top performers.
Intercept™ Insulating Glass provides these important advantages:
Thermal Efficiency: Excellent U-and-R-insulation values save money on heating and cooling costs.
Warm Edge Technology: Keeps perimeter areas of the window glass warmer, drastically reducing condensation on the inside window surface.
Glass Temperatures: Warmer interior glass temperatures allow higher relative humidity in the home, retaining heat better and increasing comfort.
Performance: One-piece, sealed spacer effectively retains insulating gas and maintains thermal performance longer.
Tight Seal: Intercept™ I.G. spacer resists seal failures due to thermal cycling because the steel spacer itself absorbs the thermal stress instead of the adhesive.
Aesthetically Pleasing: Intercept™ I.G. spacer's unique design gives the window a more "open" look since the spacer is hidden from sight by the window frame.
