Nearly half of the heat lost from solid-walled homes escapes through the walls. Insulating these will keep your home warmer, and feel like a more pleasant place, eliminating drafts and cpld spots, as well as saving you valuable energy and money, and reducing your home´s carbon footprint.
External Wall Insulation (EWI) is suitable for a variety of wall types, including brick, stone, steel-framed and concrete constructions.
What does external wall insulation involve?
External solid wall insulation involves adding a layer of insulating material to the outside walls of a building and coating this with a protective render or cladding. There are lots of options to create the finish that you want and these may even add value to your home. The total depth of this layer ranges from around 50mm to 130mm, depending on the system used.
External solid wall insulation, rather than internal, may be particularly suitable if you want to avoid any loss of space or the disruption of work going on inside your house, or if you are doing other work to the exterior of your property, such as re-rendering.
Changes to the external appearance
Installing external wall insulation will not reduce the size of your rooms (unlike internal solid wall insulation), although you may require planning permission if it changes the appearance of the property. There are a wide range of colours and finishes which we can be apply, though often the existing finish can be replicated to preserve much of the home´s original appearance, if that is what is desired.
Planning Permission
As solid wall insulation is now constituted as an ‘improvement’ rather than an ‘enlargement’ you are unlikely to need planning permission unless your house is listed or is in a national park, area of outstanding natural beauty, conservation area or world heritage site. If in doubt, check with your local authority before having any work done.
