Pella’s Impervia extreme climate windows
Pella is expanding its Impervia window line to include casement and awning windows. Pella claims that the windows, made with its Duracast composite, can withstand most climatic extremes and are easier to maintain than the vinyl or aluminum equivalents. Available with white, tan, and brown mullions, the new windows also have several framing options and hardware finishes. pellacommercial.com
