Before installing external wall insulation, it’s essential to carry out a render test if the property already has existing render. This test determines whether the render is strong enough to support the insulation. If the render is found to be inadequate, it will need to be completely removed before the insulation can be attached directly to the brickwork. However, if the render is securely in place, it can be smoothed down and the insulation applied directly onto it.

Another crucial step before installing external wall insulation is to remove any external pipework from the building. These will be reinstalled once the insulation process is complete, and in some cases, they may need to be extended. This is one of the primary reasons why the insulation process can be both costly and time-consuming.

The insulation panels are fixed to the exterior walls using adhesive mortar. An insulating mesh is then embedded into the mortar to secure the panels in position. Finally, cladding or render, such as brick or stone tiles in your chosen colour, is applied to create a decorative finish.

Please Note: That installing external wall insulation will significantly alter the appearance of your property. It is advisable to check with your local council to see if planning permission is required before proceeding.
