Insulation for
Weatherboard Walls

Industry leading high
performance retrofit wall
insulation for weatherboard homes.

How do we insulate your weatherboard walls?

At CosyWall Insulation, we specialise in insulating homes with weatherboard exterior cladding. Our process involves carefully installing insulation between the weatherboards and interior walls, effectively trapping heat and reducing energy costs. Our team of experts takes care to ensure a seamless and efficient installation, resulting in a warm and comfortable home all year round.

To start, our technicians will assess the weatherboard wall to ensure it’s suitable for insulation and determine the best access points for blowing the insulation into the wall. Using specialised equipment, we blow the insulation through small holes drilled in the cladding. Our process ensures that the insulation is evenly distributed and fills all gaps and cavities in the wall. The holes are then sealed, using a special filler to prevent heat loss and ensure weather-tightness. The filler is then sanded down ready for repainting.

The entire process is quick, tidy, and non-invasive, making it the perfect solution for homeowners who want to improve the insulation in their weatherboard homes without disrupting their lives. With CosyWall, you can enjoy a warmer, more energy-efficient home in no time!

Installation process for weatherboard walls.

It’s as easy as one, two, three.


Prepare the walls

We start by preparing your walls to be insulated. We do this by drilling small holes into the weatherboard cladding through which Insulation can be installed.

We take the greatest of care when adding penetrations to your weatherboard walls to ensure they can be easily repaired once wall insulation has been installed.


Fill the walls

Once your weatherboard walls are prepared for insulation, we are able to fill them with CosyWall. Wall Insulation is blown into your weatherboard cavity using specialised equipment to ensure the right thermal densities are achieved.

CosyWall Insulation is ideal for retrofitting a older weatherboard home with wall insulation because it properly insulates into all the gaps and voids which are often left uninsulated by other products.


Repair the walls

Once your weatherboard walls have been insulated, we go through a repair process to ensure they are weathertight. This includes filling, sanding and repainting all penetrations.

Once we’ve completed the process you’ll never know we were there and all you’ll be left with is a nice and cosy, more energy efficient home.
