Pella Impervia windows and patio doors are built from Pella's proprietary fiberglass, engineered for exceptional strength and tested to perform in extreme heat and cold. Because fiberglass expands and contracts at nearly the same rate as glass, seals stay tight through decades of Minnesota freeze-thaw cycles.
Impervia's strength allows slim frames with clean, modern sightlines, and its powder-coat finish resists fading — including in black and other dark colors. It's an outstanding long-term choice for our climate: tougher than vinyl, more affordable than wood.
