Thermal Performance of Glass
NOT ALL LOW E IS CREATED EQUAL
Seaway’s high performance Low E is our standard Low E, and has a double thickness of silver and a hard outer layer of titanium to provide extraordinary performance in climates where reducing both heating and cooling costs are important. Seaway’s high performance Low E has a clear appearance with minimal tint, yet it can keep the summer heat and the winter cold outside, giving you year round comfort.
Seaway uses advanced Intercept™ technology as a standard to create insulated glass with a warm edge around the perimeter. The edge of the glass is typically the coldest spot on the window and can be prone to condensation. Other windows utilize glass panes with rectangular aluminum which conducts the heat away from the inner pane of glass resulting in a cold edge. Intercept spacers, instead, use a thin steel U channel that reduces conductivity and keeps the edge of the glass warm.
Seaway also offers Super Spacer®, a non-metallic structural foam spacer, as an option for the absolute finest in warm edge spacers. Super Spacer blocks heat escape, dramatically reduces condensation and offsets the effects of temperature changes that create stress cracks.
All Seaway windows with high performance SpectralCoat Low E glass also receive argon gas fill between the panes of glass. Krypton gas fill is available as an optional upgrade. Argon and krypton are harmless and odorless rare earth gases that are found in minute amounts in the air. When concentrated, argon and krypton gas are more dense and viscous than air, reducing the convective heat loss from between the glass panes and have lower thermal conductance, thus reducing conductive heat loss through the glass unit itself. Many companies charge extra for argon gas, but with Seaway it is part of our standard high performance low E package.
