## Frequently asked questions

### Can I have cavity wall insulation?

Most brick veneer and double brick homes have a gap that can be filled. Solid brick has no gap, so this job does not apply. An installer checks the cavity is clear before drilling the mortar.

### What is the best insulation for walls in Australia?

The best insulation for walls in Australia typically includes materials like expanded polystyrene, mineral wool, and polyurethane foam, depending on your specific needs.

### Why is my house so cold even with cavity wall insulation?

Your house may feel cold due to factors like poor installation, inadequate insulation, or air leaks elsewhere in your home.

### Can brick veneer be insulated?

Brick veneer has a cavity behind the outer brick. Installers blow or pump the fill in through small holes in the mortar, then patch the holes.

### What is the R-value of a brick veneer wall?

The R-value of a brick veneer wall typically ranges between 1.0 to 1.5, depending on thickness and insulation used.

### Is it worth getting cavity wall insulation?

A filled cavity slows heat moving through the walls, so the house holds its temperature with less heating and cooling. The cavity has to be clear, and the holes in the mortar are patched when the job is done.

### What are the downsides of cavity wall insulation?

Some downsides include the potential for moisture issues if not properly installed and the need for professional installation.

### Can you insulate a 50mm cavity wall?

A 50 mm cavity is narrow, but blown mineral wool or beads can still go in through drilled mortar holes. The installer checks the gap is clear first.
