Energy Advantage Low-e Glass

The 'e' stands for emissivity. Two thirds of the total heat loss in a standard patio doors occurs because the warm inner pane readily emits heat to the cooler outside pane. North Star builds improved energy efficiency into every patio door it makes by using only specially treated Low-e glass to disrupt this loss of heat in the winter . . . and the heat gain that occurs in the summer. North Star's Low-e glass is not a tint or a reflective coating, which often reduces the amount of visible light in a house. Our specially applied product keeps heat where it belongs, while ensuring your home remains bright. In addition, double strength tempered glass ensures your door is always as safe as it is beautiful.



Edgetech Premium Super Spacer®

North Star patio doors use Edgetech Premium Super Spacer® between glass panes to resist condensation, reduce noise and boost insulation values by as much as 30 per cent. Edgetech Premium Super Spacer® warm-edge technology reduces the escape of heat and air-conditioned air at the perimeter of the glass, the area most vulnerable to condensation, heat loss and frosting. Not only can condensation damage frames over time, but it can contribute to the unhealthy growth of mould. The advance with Edgetech Premium Super Spacer® is an all-foam spacer construction than contains no heat-conducting metal. Edgetech Premium Super Spacer® provides one of the best thermal performances in the industry.

Beginning with only premium compounds to create our vinyl, the AAMA-certified extrusions are then tested and measured on an hourly basis by a computerized system that ensures specifications are always met or exceeded.


Tempered Glass

The glass in all North Star doors is double strength or better as a standard feature, and meets or exceeds industry standards. The tempered glass makes your door safer. The added strength (up to four times greater than conventional glass) of tempered glass means it can withstand blows that would shatter other glass. Consequently, there's less chance of injury if it breaks because fragments are smaller.
