External wall insulation is the best solution for achieving a warmer environment in existing houses and it is the most cost effective and complete way of insulating your home to provide a uniform level of insulation throughout.

External insulation involves fixing insulation materials such as mineral wool or expanded polystyrene slabs to the outer surface of the wall. This insulation is covered with a special cement-based render to provide weather resistance. A steel or fibreglass mesh is embedded in this render to provide strength and impact resistance. It may be necessary to extend eaves and sills and relocate downpipes.

There are a number of different products which can be used in externally insulating homes and we strive to select the product and finish that best meets each clients requirements. Our professionals meet with the clients at their home and discuss which solutions will suit individual homes.
