If your home was built before the 1920s, it is likely that its exterior walls are solid walls. While having “solid” walls may seem advantageous, these walls differ from modern cavity walls in that they allow heat to escape through them. Therefore, to retain heat, save money on your heating expenses and cut your carbon dioxide emissions, you may want to consider insulating them. For more info see here.
What are the advantages of outer wall insulation?
Many advantages are offered by exterior wall insulation. Not only will you save as much as £ 490 per year on your heating costs, but without disrupting the interior of your home, your insulation will be installed.
Your insulation will enhance the appearance of your home and protect your brickwork if your exterior walls are aging. In your brickwork, it will also fill in any cracks, therefore eliminating any draughts they cause.
How are they installed?
A layer of insulation material is fixed to your walls with the help of mechanical fixtures and adhesives in order to insulate solid exterior walls. This material is covered, once in place, with protective layers of rendering or cladding.
What is the Cladding and Rendering Difference?
A variety of attractive colours and shapes, including timber panels, shingles, stones, clay tiles and aluminium panels, are available for cladding. On the other hand, rendering takes the form of a dense mixture of sand and cement that is applied over a wire mesh, or a thinner, lighter cement that is applied over a strong fiber mesh.
The finish can be smooth or textured, depending on your preferences. You can opt to paint or pebble-dash the surface if you want simple maintenance of your exterior walls.
Your preferred finish would cover the entire of your property’s exterior, including your current brickwork, which can affect your home’s appearance dramatically. You should pick your finish with the utmost of consideration for this cause.
Is My House Ideal for Insulation of External Walls?
If the exterior walls also need re-rendering work, exterior wall insulation is likely to be more cost-effective. You will want to consider investing in exterior insulation for the rear of your home if you live in an older property with an appealing façade that would not be ideal for exterior wall insulation. However, before this work is carried out, you can need planning permission, particularly if your property is listed.
