Question

Are there cavity wall insulators in canada, new zealand or australia?

Answer 1

In WA all houses are built with double brick walls. So the air cavity between the brick outside wall and the brick inside wall is the 'insulation' from the scorching Australian heat.

The only time walls are insulated is in sheds and factories where the walls are made out of Powder coated Galvanized Iron Sheeting.

Answer 2

Those wanting to insulate their houses ( mostly in the colder climates) can do so. Most modern houses all have ceiling insulation but only a few have walls done too.

Yes you can buy it if you want it, installation after could be costly though.
