External wall insulation is the best way to insulate your walls especially if your house is constructed of cavity blocks or mass concrete.
External Wall Insulation (EWI), which is also referred to as ETICS (External Thermal Insulation Composite Systems) is a method of insulating the outside walls of either a new or existing house. It involves fixing insulating materials such as expanded polystyrene slabs or mineral wool to the outer surface of the walls of a house, usually with a special adhesive and metal or plastic fixings. A base coat embedded with a reinforcing fiberglass mesh is applied to this insulation, and this is then covered with a final finishing render to provide weather resistance. Whilst external insulation is an expensive insulation solution, it can also resolve other issues, such as mould and damp, rain penetration, poor airtightness and frost damage, provided the product used is NSAI Agrément certified. This is also an excellent opportunity to give your home a new look.
