Pella Impervia windows are created from an 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.

Low maintenance. The interior and exterior of your windows and patio doors arrive with a durable powder-coat paint finish. Looks like new for years. Long-lasting factory powder-coat finish that stays looking great for years — inside and out — with little care. Pella’s environmentally friendly paint process virtually eliminates VOCs.
