Can you install into brick homes?

One of the questions we get asked on a regular basis is if we can install CosyWall Insulation into a brick home. Yes, we can install CosyWall into a brick house, and CosyWall is CodeMark certified to be installed into brick houses.

The product is a specialised German engineered product that’s been designed to be installed into the double brick cavity homes in Europe. CosyWall is designed to go against wet or damp surfaces and includes a water-repellant with specially designed fibers making it ideal for New Zealand brick homes.

What does R-Value mean?

We often get asked about R-values in CosyWall. An R-value is simply a measure of a thermal resistance of an insulation product. The higher the number the better it will retain heat inside your house.

CosyWall Insulation has the highest R-value that’s obtainable in this type of product and is equivalent to the top batts and blown insulation products available in New Zealand.

Can you install from the inside?

CosyWall Insulation can be installed from either the outside or the inside of the house.

Internal installations are usually only done when you’re renovating or redecorating the inside of the home. External installations are much easier and can be done all year round.

How long does it take to install?

Most people are surprised how quickly CosyWall Insulation can be installed. Officially it depends on the size and complexity of your home, but in most cases, the installation can be completed in 1 to 2 days.

No need to head away for the day, however, if so when you return your home will be filled with CosyWall Insulation and you won’t believe the difference!
