The things that set our Sierra Pacific windows and doors apart have big implications for longevity and performance. For starters, the exteriors of our clad wood windows and patio doors are fully encased in heavy-duty, extruded aluminum that’s twice as thick as roll-form cladding. It only takes one hailstorm to demonstrate the benefit of this.
Our wood is treated and protected against insects and moisture with our patented, naturally organic CoreGuard Plus™ preservative.Inside our world-class frames is high-performance glazing with customized options for your exact weather and environmental conditions. As a finishing touch, our insulated glass uses No-Metal TrueWarm® Edge polymer structural foam spacers. This dramatically improves energy efficiency and reduces seal failures often caused by the more common metal spacers.
