Solid Wall Insulation

Millions of households in the UK suffer from exorbitant energy bills due to their wall structure. Most properties built before 1930’s were constructed with solid walls, so they don’t have cavities that can be injected with insulation. These solid wall properties can be insulated with external solid wall insulation. The purpose of insulating in this manner is to slow the movement of heat out through the walls, thereby dramatically reducing heating demand and make your home more energy efficient. Insulating your solid walls could cut your heating costs significantly. External Wall Insulation being installed on your house means huge savings on your bills and more comfortable living space for you and your family.



How it works


Firstly, if the property has existing render, a render test must be carried out to see if it is strong enough to hold the insulation. If not, all the existing render will need to be removed prior to attaching the insulation to the brickwork. If the render test shows that the existing render is firmly held in place, the render can simply be smoothed, ready for the insulation to be applied directly on to it.

Another important step prior to installing any external wall insulation is to remove any pipework from the outside of the building. These will be reinstalled at the end of the process (and maybe extended in some instances as necessary); this is one of main reasons that the insulating process is expensive and time-consuming.


Insulation Panels are applied on the outer walls using adhesive mortar. An insulating mesh is then sunk into the mortar to hold the panels in position. Cladding or render (including brick or stonetiles) as per choice of colour is applied later to form a decorative finish.

NOTE: You should be aware that installing external wall insulation will change the appearance of your property significantly, you should check with your local council first to see if you require permission.
