Slate Insulations Ltd are your local, fully accredited installers of Solid Wall Insulation (SWI). Our etablished service extends across the South East and parts of the South West of England.


External wall insulation (EWI), also known as solid wall insulation (SWI), is an extremely effective means of insulating solid walls and is an effective way of increasing the energy efficiency of your property.

Approximately one third of the heat lost from your house is lost through its walls.

The application of an External Wall Insulation system will dramatically reduce your home's heat loss - cutting heating bills - as well as improving the external appearance of the property, possibly increasing its value as well. There's a wide choice of textures and colours to choose from.

External wall insulation involves fixing a layer of insulation material to the wall, then covering it with a special type of render (plasterwork) or cladding. The finish can be smooth, textured, painted, tiled, panelled, pebble-dashed, or finished with brick slips. As this is applied to the outside of the property, it means that there's minimal upheaval for you, the occupant.
