DuraSeal™ by Tru Seal

As a result of Kelly Window Systems determination to provide you with the best possible product offerings anywhere, we have chosen to incorporate DuraSeal™ Spacer System into our manufacturing operation. Duraseal high performance spacer system is now a standard offering in every one of our glass units. Duraseal is a revolutionary, patented system incorporating specially formulated sealant and a corrugated aluminum spacer bar. DuraSeal™ provides reduced heat transfer around the perimeter of insulating glass units resulting in warmer interior glass temperature in the winter (9°F on average) and cooler interior glass temperature in the summer. DuraSeal™ has been tested and proven to reduce condensation on windows by 80%  by providing better insulation of the glass edges. This advanced spacer technology is guaranteed to help reduce heating and cooling costs in your home by reducing the heat transfer through the glass.
