From the constant drizzle
of the Northwest,
to the frigid winds
and dramatic winter storms
of Maine, to the sun and
swelter of the Gulf Coast,
CertainTeed windows have
endured the worst. That
means you can relax and
stay comfortable, wherever
you are.
For comfort.
Bryn Mawr II windows
have been extensively
tested to resist air and
water infiltration nearly
100% better than minimum
AAMA standards. But
that's just the start. They
also resist condensation
- with a condensation
resistance factor (CRF)
that's almost twice the
AAMA standard. And they
even reduce noise - with a
sound transmission rating
(STC) that's better than a
4-inch cinder block wall.
For thermal efficiency.
To help save energy
costs in both the heating
and cooling seasons,
Bryn Mawr II windows are
glazed with CertainTeed's
proprietary Thermaflect
Low "E" glass. A special
coating - two microscopic
layers of silver versus one
on ordinary Low "E" -
gives it additional sensitivity
that scientifically selects
the most beneficial wavelengths
of light and heat and
blocks the others.
A highly effective system
is created when Thermaflect
is combined with a lowconductance
spacer and
argon gas. The low-conductance
spacer reduces the loss
of heat through the edges
of the glass unit, while the
argon gas, which is added
between the panes, increases
the insulation value of the
double-pane unit.
Thermaflect has the best
R-value in its class to help
save energy in cold weather.
It also significantly reduces
unwanted heat in warm
weather. It blocks 84% of
the ultraviolet rays that can
fade and damage fabrics
and carpets. And it
does all this while
letting in high levels
of daylight for a
natural view.
