Tracy Rogers, vice-president of sales and marketing for Keystone Certifications, presents the results of a one-year study he performed at Quanex on the effects of adding a retrofit insulating glass layer to the existing single-pane windows in an older commercial building in Philadelphia.

Using careful science and detailed descriptions of the approach taken, Rogers convincingly shows the benefits of IG retrofits with a full discussion of costs and energy savings. After monitoring two pairs of side by side rooms for a year, one pair with the new system and one without, Rogers’ team discovered 40 to 60 per cent heating cost reductions using a system that could be installed from the interior of the building at night without removing the old windows. Daytime summer temperatures near the old windows approached 40 degrees, but dropped to high 20s after the retrofit. Architects and contractors involved in renovating older buildings will benefit from Rogers’ comprehensive review of this new method for updating old fenestration.
