How do I insulate the walls of my old house?

Many of us have insulated our ceilings and floors, but what do we do about our weatherboard walls??? Up to 25% of heat loss is through the walls, and an even greater percentage once the ceilings and floors are done!

Waterworks Valley community group has produced an excellent pamphlet describing how it is possible to retrofit insulation into the walls of an existing building. There are ways to insulate from the inside and also from the outside! This pamphlet gives tips on what to avoid, and names some useful suppliers in the Hobart area.
