“One day all windows will be installed this way,” predicts Alan Fielder, Director of Sales and Marketing at the recent launch of TruFit by Edgetech UK, a Quanex company.
“We’ve shown that TruFit is the best way to install windows for energy efficiency. And it has the added benefit of being quick – up to 20 percent faster – simple and very clean to fit.”

TruFit is a pre-compressed foam window sealing tape for window and door installation. It provides an effective thermal barrier at the edge gap between the window or door frame and the reveal. This ensures true energy rating performance and a long-life weather seal. The results in thermal imaging are impressive. Tests of installations with traditional sealant showed how much heat is lost at the edge of the windows. When the same window was fitted using TruFit there was on average 23 percent less heat lost around the window fitted.

“It’s not a question of good or bad installation techniques,” adds Alan. “TruFit works by expanding to effectively seal all gaps and spaces between the frame and wall.” TruFit also improves comfort levels because it reduces draughts caused by cold spots. This is recognised as one of the best ways to reduce heating bills. Even the slightest draft can make us ‘feel cold’ and we often turn up the thermostat to compensate. Take away the draughts and the ambient temperature maintains at a more even level giving us the highest level of comfort.

“TruFit not only saves money for installers and property owners it’s also a great sales opportunity. With so many benefits we believe that all windows in the future will be installed this way. Don’t just fit it, TruFit it!”
