How to insulate an exterior wall

Render test

The first step in installing exterior wall insulation is a render test. This test will determine if the render is strong enough to support insulation. If the render is strong enough, it can be smoothed so that insulation can be applied immediately. It must be strong enough for insulation to be applied.

Pipework can easily be removed and modified

Before the installation can start, it is important that the render has been tested and smoothed. Temporary downpipes are required to stop water running down the building's sides. Also, soil and waste pipes must be removed. This will allow the building to continue its normal operation during installation.

Windows should not be protected

Professional companies often install a protective film or layer on your doors and windows to prevent damage during installation.

A starter track

Before insulation can begin, it is important to measure the insulation's height. The ground is not usually reached by external wall insulation. It is placed a few inches above ground. Once you have established the height, the aluminum carrier tray/start track will be installed. This is a level starting point and can be used for beading.

Insulation boards

After the starter track has been installed, insulation boards can then be applied to the wall. Once each board is coated with adhesive they can be adhered to the wall in a logical order. After windows or other obstructions are removed, the insulation boards can be cut to fit around them. After the insulation boards are all installed, you can remove any edges with a rasp. This will ensure that your surface is completely flat.

Mechanical fixings

You can attach insulation boards using mechanical fixings. There are about 10 fixings per square feet for insulation boards that are resistant to windblown or falling apart in bad weather.

Adding beading

For ensuring that insulation is secure around doors and windows, corner beads or stop beads can be used.

Add reinforcement mesh to

Two layers with strengthening properties are applied after all boards have been installed. A fibreglass mesh is sandwiched between the layers.

Primer

After the reinforcing mesh has been installed, primer is applied. Primers often contain granules which help the final render coat stick to the surface. To ensure that no colours show through, primers are often color-matched to the final render.

Final render

Now you can apply the final coat. The exterior will now be finished with the final coat.

Reinstall pipework

All fixtures and pipework can be removed from the walls. Seal all openings with pipework that runs through the render. Your windows' sills may need to be made deeper after the exterior wall insulation has been installed. You can do this by either adding sills to your existing windows or by extending them. You might have to add verge trims at the roof-wall junction that are either longer or wider in order to extend the new wall.
