If your home was built before the 1920s, it is possible that its exterior walls are solid walls. While having “solid” walls may seem beneficial, these walls differ from modern cavity walls in that they allow heat to escape through them. Therefore, to maintain heat, save money on your heating expenses and cut your carbon dioxide emissions, you may want to consider insulating them.You may want to check out Bone Dry Roofing for more.
What are the benefits of outer wall insulation?
Many advantages are provided by exterior wall insulation. Not only can you save as much as £490 a year on your heating bills, but without disrupting the interior of your house, your insulation will be built. Your insulation will enhance the look of your home and protect your brickwork if your exterior walls are aged. In your brickwork, it will also fill in any gaps, thus removing any draughts they create.
How are they installed?
A sheet of insulation material is applied to the walls with the aid of mechanical fixtures and adhesives in order to insulate solid exterior walls. This material is protected, once in place, with protective layers of rendering or cladding.
What is the Cladding and Rendering Difference?
A variety of appealing colours and shapes, including timber sheets, shingles, bricks, clay tiles and aluminium sheets, are available for cladding. In the other side, 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 solid fibre mesh.
The finish can be smooth or textured, depending on your preferences. You can choose to paint or pebble-dash the surface if you want easy maintenance of your exterior walls. Your chosen finish will cover the whole of your property’s exterior, including your existing brickwork, and can change your home ‘s appearance significantly. You should select your finish with the greatest of consideration for this reason.
Is My Home Appropriate for Insulation of Exterior Walls?
If your exterior walls already require re-rendering work, exterior wall insulation is likely to be more cost-effective. You may want to consider investing in exterior insulation for the rear of your property 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.
How are new building laws impacting my work on insulation?
You must ensure that the work complies with current Building Codes if you want to insulate a solid wall. The primary condition to adhere to is your insulated wall ‘s thermal efficiency. The wall must have a U-value of a maximum of 0.30 W / m2 K if you live in England or Wales. The U-value is a metric of the rate at which heat can pass through your wall. The lower the U-value, the cheaper it will definitely be for your heating bills.
Your contractor will need to make sure your desired insulation work is capable of compliance with current building codes and should preferably obtain approval on your behalf from the local building control office.
