CertainTeed uPVC window frames will
not sustain
combustion like timber.
The uPVC frames have
no paint and
no
varnish which burn at relatively low temperatures and do
not
conduct heat like aluminium.
Even if exposed to direct flame, uPVC could gain you precious
extra time to fight or flee a fire.
The double glazing increases your heat barrier and metal insect
screens help resist radiant heat.
"All
gaps around doors, windows and eaves should be sealed to improve
energy efficiency and reduce entry points for embers."
One reason CertainTeed windows work so well is that they seal
effectively, keeping out ember bearing winds as surely as winter
draughts.
"Windows
designed for improved thermal performance protect the house
from heat transfer during a fire."
Thermal performance is a major reason for CertainTeed's
international success. (Another is acoustic performance).
If you are seriously concerned about the bushfire risk in your
area, we recommend you opt for toughened glass to further resist
sudden temperature changes.
