Why Choose Pella Impervia Windows?

Lasting durability with beauty and energy efficiency.

Rot- and corrosion-free. Our durable fiberglass will never rot or corrode, is naturally resistant to water and bugs and virtually maintenance free.

No painting or refinishing. A tough powder-coat finish resists chipping, chalking and fading — so you never need to paint or refinish.

Tested to withstand harsh conditions. Pella’s proprietary, low-maintenance fiberglass is tested to withstand some of the harshest conditions, including extreme heat and sub-zero cold, damaging UV rays and seacoast environments.16
