Our Installation Process

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 your cladding or plasterboard through which CosyWall Insulation can be installed.

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


Fill the walls

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

Blown wall insulation is ideal when adding retrofit insulation to your home as it gets into all the gaps and voids which are often left uninsulated by other products.


Repair the walls

Once your 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.
