Delivering Unmatched Strength and Style
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.
