$$-$$$
Pella Impervia picture windows are non-operable. Because they do not open or close, the design helps improve your home’s energy efficiency. Optional extruded aluminum grilles are adhered to both sides of the insulating glass to provide the look of aluminum storefront windows.69 Clean, minimal lines allow for more visible glass — making these windows a great option for modern homes.

Inside Pella Fiberglass
Pella Impervia windows are created from our exclusive fiberglass formula. A structural mat places rovings in a specific, intricate order to meet our high strength standards. Additional layers of strategically placed rovings are added, then the materials are pulled through a machine, injected with polymer resin and heated. It creates an entirely new, thermoset material which won't break down when exposed to the elements or lose its shape in extreme heat — unlike other materials.
