Pella®
Impervia®
Advanced
alternative.
Lasting
value.
Pella
Impervia
windows
and patio
doors
combine
the beauty
you expect
from Pella
with the
durability
to be
virtually
impervious
to all
weather
conditions.
They're
made of
Pella's
patented
fiberglass
composite
called
Duracast® –
the
strongest,
most
durable
material
available
in windows
and patio
doors.*
That means
Pella
Impervia
products
can take
almost
anything
nature or
your
family can
dish out.
Including
extremely
hot or
cold
weather,
impacts,
scratches,
sea air
– even
damaging
UV rays.
Plus,
they're
low-maintenance
and
incredibly
energy
efficient.
But the
real
strength
of Pella
Impervia
windows
and doors
is their
value.
Duracast
is nine
times
stronger
than
vinyl.*
And
competitively
priced.
*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.
