What is Cavity Wall Insulation (CWI)? 

Cavity wall insulation (CWI) is a type of insulation inserted into the space inside the walls of a property – the cavity. The cavity is formed by two walls of brickwork built close together, between which the insulation can be inserted.

Most homes built after 1920 have cavities, whereas older homes tend to have solid walls. More modern properties are usually constructed with a layer of insulation boarding between the walls, especially if they have been built in the last 20 years.

There are many types of CWI for different property types, including mineral wool, bead or foam.

What is an External Wall Insulation System (EWIS)?

External wall insulation (or EWI), is insulation fitted to the outside of a home, where cavity walls are not present. These tend to be properties of solid wall construction or system-built homes with steel or timber frames.

EWI will change the visual appearance of a property and many architects, and contractors choose to install it to improve the aesthetics of the properties they are renovating.

EWI systems are usually made up of expanded polystyrene, mineral wool, polyurethane foam or phenolic foam, topped off with a reinforced cement-based, mineral or synthetic finish and plaster.
