Why you need Wall Insulation?

Adequate insulation in the walls of your home will minimise the transfer of heat!

With colder weather just around the corner, it’s time to start thinking about how to keep your homes warm and cosy. One of the biggest factors that help reduce cold air entering your home and keeping the heat in is insulation.

While many homes have ceiling and underfloor insulation, we find wall insulation has generally not been installed or overlooked. This means that for most older NZ homes, heat escapes through the walls making the home difficult to heat, and often leading to other health issues.

CosyWall Installation Process

STEP 1 - Preparing the walls

Insulation is blown into your home through small holes drilled into your wall cavity. In order to prepare your walls for insulation, we go around the interior or exterior of your house and create access points to install the insulation.

STEP 2 - Filling the walls

Using specialised equipment, we then blow CosyWall Insulation into the walls of your house.

CosyWall is blown in at such a high density that it’s never going to shrink or slump inside your walls.The product is not going to deteriorate over time, and once it’s in your walls, it’s there to stay. It will continue performing day in, day out and will never cost you a cent to run.

STEP 3 - Weathertightness

Once CosyWall has been blown into your walls, we will go around and seal all the holes with a special compound that ensures your house will remain weathertight.

Ensuring your home remains weathertight once we finish is one of the key factors to ensure we comply with Government regulations. You can rest assured that we take our responsibilities here seriously.

STEP 4 - Finishing Touches

The final step in our installation process is to ensure that we leave your home the way we found it. We’ll make sure we repaint or touch up any areas of the home to ensure that when we leave the property, the only evidence you’ll have that we were ever there is the warm and comfortable environment you’ll now be able to enjoy.

Does the hole size matter when installing blown insulation?

At CosyWall, we often get questions about the size of the hole we blow through. We’ve been blowing insulation into New Zealand homes for more than 18 years, and over this time we’ve tried different hole sizes from large to very small to test the difference in installation quality and performance.

What we’ve found is that there is an optimum whole size that enables us to do the job properly, and we choose that hole size based on your specific house. If you’d like to know more, please contact the team at CosyWall and we’d be happy to chat!
