Northerm Adds Quad-Pane Line

March 24, 2009

While many window and door manufacturers are considering the addition of triple-pane windows to their line, Northerm Windows recently introduced a quad-pane product line to meet the needs of its customers in Northern Canada and Alaska.

Northerm is based out of a 54,000 square foot facility in Whitehorse, Yukon, Canada, with an additional 30,000 square-foot manufacturing plant in Anchorage, Alaska. Founded in 1985, the company specializes in windows designed for the extreme elements of the Yukon, Northern British Columbia, Alaska and permafrost-covered areas of the Arctic. Currently, triple-pane windows account for about 90 percent of its business, the company reports.

“We were presented with a challenge by our local housing authority to build a system that would reduce energy costs even more for customers, and that is what we did,” says David Borud, general manager of Northerm in Whitehorse. “During the development stage we looked at a variety of options and came up with a combination of materials that provided best in comfort, energy savings and acoustics. The materials in the 4000 Series also provide assurance of long-term durability, even in temperatures that can range from -40° C to +5° C in less than 24 hours.”

The quad-pane 4000 Series IG units are constructed with Super Spacer from Edgetech I.G, low-E coatings on surfaces two and seven, and argon gas in all three airspaces, resulting in an .103 U-Value, the company reports.

“Expansion and contraction due to temperature and pressure changes, wind and snow puts a lot of stress on windows,” Borud notes. “Super Spacer is flexible and will not cause stress cracks and premature seal failure. We have used Super Spacer since 1998, and it’s amazing how few warranty claims we’ve had over the years.”
