Insulation: External/Internal Dry Lining
Internal Wall Insulation
If your home is built using solid wall or hollow block construction methods, cavity fill insulation is not an option. Internal insulation (sometimes referred to as 'dry-lining') involves fixing insulation to the inner surfaces of your external walls. This usually involves fixing an insulation board to the walls and covering it with a vapour barrier layer and plasterboard. One of the main disadvantages of internal insulation is the loss of room space; this may be minimised by using high performance insulation products that are thinner. While this is often a more affordable option than installing external wall insulation, the loss of space and potential necessity to take out and re-fit fitted kitchens and appliances can result in people choosing the external insulation option.

External Wall Insulation
External insulation involves fixing insulating materials such as mineral wool or expanded polystyrene slabs to the outer surface of the wall. The insulation is then covered with a special render to provide weather resistance. A steel or fibreglass mesh is embedded in this render to provide strength and impact resistance. External insulation is an expensive solution; however additional problems (other than poor levels of insulation) suffered by some homes such as rain penetration, poor airtightness or frost damage can be solved by an external insulation system, provided that the product is NSAI Agrément certified.
