QSI products meet or exceed the Energy Star and CSA requirements in Canada. The stringent Most Efficient Energy 2014 requirements are met using QSI SCR-10 insulating glass package.

A triple glass unit comprised of two panes of Low-e glass, one of clear glass’ sealed with non conductive silicone foam Super Spacer and the chambers filled with 90%+ Krypton gas.

QSI SCR-10 triple glass package will also provide you the ultimate warmest inside surface to reduce or eliminate condensation in the coldest winter weather. The sound proofing value in casement and fixed windows just doesn’t get any better.

At QSI the focus is on comfort and performance……the energy savings are a given, especially important as fuel prices continue to rise.

Low emissive or ‘Low-e’ glass has a special thin metallic oxide coating on the interior surface, which allows the passage of short-wave solar energy (light) as well as reducing the passage of long-wave energy (heat) from the sun or heating systems through the glass. Also up to 99% of the ultra violet (UV) rays are blocked, protecting curtains, flooring and furniture.
Triple pane consists of two panes of Low-e coated glass with a clear centre pane, creating two insulating chambers. These chambers are filled with either Krypton or Argon gas. Triple pane glass will provide maximum R-values, reduced noise and maximum blockage from the suns harmful UV rays.
Krypton gas is denser than argon creating the ultimate insulation barrier. Krypton performs best in smaller insulated air spaces. This is the ideal compliment to triple pane in sliding series windows which do not have the ability to widen the glass space. The goal of achieving the ultimate insulating glass R-values and maximum comfort are realized using Krypton.
Super Spacer® is the world’s only 100% polymer silicone foam, non-metal warm edge spacer bar system, providing one of the best thermal performances in the industry. The edge of the insulating glass unit is indeed most vulnerable to heat loss, condensation and frosting.
The industry standard argon gas is an inert gas that is 40% denser than air. When a double pane glass is combined with Low-e glass, argon gas improves the efficiency your window by 30% over an air filled thermo pane. Argon gas best performs with 1/2.
