However, while it is relatively simple to
inspect for signs of termite activity on
ancillary timbers inside the home, or
around piers or a well-maintained slab
outside, it is generally impossible to
inspect a wall frame.

A timber-framed home with a chemical
or physical barrier can still be subject
to termite attack. This is confirmed by
published studies undertaken by the
Timber Development Association,
which note significant levels of termite
infestation in timber-framed homes less
than 50 years old.

It is also worth considering the "human
factor" - the effectiveness of the physical
or chemical barrier is only as good as
the quality of the installation.

If the frame itself is attacked, the cost
of the repair is replacement can be
enormous. The frame is one of the
biggest cost components in the home.

This is where the so-called "whole of
home" argument falls flat. A genuine
"whole of home" policy would ensure
that the framing material - the least
visible and potentially costly element
to replace - was made from a termite-
proof material, such as steel.

The reality is that steel framing provides "in-built" protection
and genuine peace of mind for homeowners, builders and
regulators.

The frame is among the most
expensive component to repair or
replace, but one of the easiest to
protect absolutely by choosing a
totally termite resistant material.
