Ultrex® fiberglass stability
Ultrex is an ideal material for windows not only for its amazing strength
and ability to repel the elements, but also for its low thermal expansion rate.
Cold, heat and time can be tough on some window materials. Vinyl, for
instance, can distort in extreme heat due to its high thermal expansion rate
(see chart above). Ultrex resists distortion even at temperatures up to 350°F.
Rapid temperature change doesn’t faze it either. When the mercury climbed
from -30°F to 70°F, a 6' stile changed less than 1/32" in length!

Ultrex and glass expand at virtually
the same minimal rate, which means
the entire window will stay tightly
sealed—no cracks in the material
or leakage around the glass.
