CHECKLIST FOR
DOUBLE
GLAZING
For best performance, look for the following:
Frames that have a thermal break or are made of
insulating materials - a plastic or resin section in the
centre of the aluminium joinery or frames made from an
insulating material, such as uPVC or wood. These are
less likely to attract condensation and will lose less heat
than windows with standard aluminium frames.
Compared to standard aluminium frames, thermally
broken aluminium frames reduce window heat loss by
about 20% and uPVC or wooden frames by about 40%.
