Pella Impervia windows combine the
beauty you expect from Pella with the
durability to be virtually impervious to all
weather conditions. Made of Pella's patented
fiberglass composite called Duracast® — the
strongest, most durable material available
in windows and patio doors* — Pella Impervia
products can take almost anything Mother
Nature or your family can dish out.
Including extremely hot or cold weather,
impacts, scratches, sea air — even damaging
UV rays. Plus, they're virtually
maintenance-free and incredibly
energy-efficient.
But the real strength of Pella Impervia
windows and doors is their price. Duracast
is nine times stronger than vinyl*, but
competitively priced. Just another way Pella
Impervia products take outstanding value to
the extreme.
* In testing performed in accordance with
ASTM testing standards, Pella's Duracast has
displayed superior performance in strength,
ability to withstand extreme heat and cold,
and resistance to dents and scratches.
