The U value is a measure of how quickly heat escapes from your home. The lower the figure, the less heat escapes. A solid wall home will generally be around 2.0 whereas a new, well insulated home will have a U value of about 0.25 - which is almost ten times better!

External Wall Insulation (EWI) is the most thermally effective way of insulating solid wall houses. DJM Exteriors install using the most affordable and accredited materials and systems.

This depends on the size of your property and the weather. On a small property like a terraced house in the summer it can be completed in a week. However, a large property in late autumn could take up to 3 weeks.

There are several advantages. The main advantage is that you do not lose any internal space as all the insulation is on the outside walls. There is no need to vacate the house or rooms whilst the work takes place, no need to move furniture and internal fittings and no internal redecoration is required. It allows thicker, higher performing insulation to be used resulting in warmer walls. A final advantage is the elimination of any risk of condensation and cold- bridging as the whole building is essentially wrapped in an insulating skin.

Insulation boards are attached to the wall using a special adhesive which is applied to the rear of each insulation board before being laid onto the wall in a staggered pattern. The boards are then further secured by being mechanically drilled and pinned to the wall. At the base of the wall the boards sit in a base rail set at the height of the damp proof course.
