The Pella Impervia window line offers excellent performance from the exterior and superior insulation, comfort, and convenience from the interior.


Its flat, clean lines and colonial proportions enhance any home, while its six-point seal adds a whole new level of weather resistance. These fiberglass windows boast an advanced insulated glass formulation for exceptional heat retention in winter and extreme heat protection in summer.
