Windows & Door Profiles
One of the major uses of rigid PVC in construction
in Europe and the US is as profiles for windows and
doors. The PVC window market in Australia is only more
recently being developed.
In Europe, some 40 per cent of all window profiles
are made from PVC. Specifiers and consumers choose PVC
windows because they are tough and durable, require
low maintenance, do not rot, offer design flexibility,
are competitive in terms of price, and can be easily
processed and fabricated. Double-glazed PVC windows
offer excellent thermal and acoustic properties, qualities
which are now increasingly recognised in urban developments
in this country.
The main alternatives to PVC for window frames are
wood and aluminium. Metal window frames conduct heat
and cold, reducing thermal efficiency. Although timber
frames are good insulators, they weather and need a
lot of maintenance. Various ecobalance studies have
been undertaken internationally to compare the materials
used in window profiles. These have shown that, in window
profile applications, PVC has a good ecological balance
when compared to wood and generally much better compared
to aluminium.
In Australia, PVC windows have been installed in a
range of residential home designs and apartment buildings.
