Existing Wall Insulation

Existing Walls

How do you insulate existing walls in older houses?

To insulate existing walls we remove tiles or iron to allow access to the wall cavity from your roof.

Most older homes have a 75mm gap between the brick and the timber and another 90mm from the timber to the plaster board. If it is a brick veneer home, we can pump Rockwall by dropping a hose and filling the wall from the bottom of the cavity.

In a brick veneer home there will generally be a wall gap allowing up to 165mm thickness of insulation – much thicker than the standard homes built these days which have no greater than 90mm of insulation installed in their walls. Rockwall is a water repellant insulation so it prevents any moisture going through the material from your external wall.
