External wall insulation involves fixing a layer of insulation material to the outer wall of a property, which is not of cavity construction, then covering it with render or cladding. A choice of finish is available; smooth, painted, textured, tiled, panelled or pebble-dashed.
This technique is an excellent solution to raising the thermal efficiency of existing homes where, in the past, any other external improvement may have proven difficult or even impossible. For the insulation to be as effective as possible an initial suitability check of the surface is required and the application needs to be carried out in optimum weather conditions.
At A&M we use the Knauf ThermoShell EWI system which is installed in line with the manufacturer’s instructions. The finish is highly durable and resistant to adverse weather conditions, so extremely long-lasting.
The process includes the removal of all external wall furniture such as satellite dishes and doorbells; the attachment of a supporting track around the bottom of the property at damp course level; insulation boards bonded to the external walls using a cement-based adhesive, followed by a fixing head, basecoat render and glass fibre mesh to prevent cracking in future years; and finishing off with a barrier of primer and topcoat render.
As a result, the property will have a clean, fresh and distinctive look and a maintenance-free finish that will not require decorating for many years.
