EWI or External Wall Insulation
The external walls of properties built prior to and around 1920 are likely to be of solid rather than cavity wall construction. Cavity walls are made up of two ‘skins’ or layers with a gap between them which acts as an air barrier to reduce heat loss. Solid walls do not have this gap, meaning heat can pass through them more easily, solid wall constructed buildings can have as much of 45% heat loss, hence they can be physically cold and damp to the touch.
In order to combat these problems, we can supply and fix expanded polystyrene or phenolic insulation boards to the external face of solid walls and apply a choice of pre-coloured render finishes from a variety of manufacturers. As with render only systems we are trained and accredited to install for a variety of leading manufacturers.
External wall insulation systems coupled with a good heating system will significantly reduce heat loss and in turn, significantly reduce heating costs and lower your utility costs, the added bonus is that you will also give your property a facelift whilst doing your bit to help the environment by bringing the u-value down and saving money at the same time!
External Wall Insulation can also be carried out on properties with cavity walls that aren’t suitable for cavity wall insulation and other non-traditional housing types. We also supply and fix window sill extensions and bespoke coated-polystyrene architectural profiles.
