Reduces heat loss by up to 45 % from your home
External wall insulation is a highly advanced insulation system that is applied to a house’s outside walls. The system comprises of a layer of insulation, a layer of insulating render implanted with reinforcing mesh, followed by a final coat of render finished to the desired decorative effect.
External wall insulation is a particularly effective method of insulation for homes constructed from solid walls, referred to by some as ‘hard to treat’, because quite simply they have no cavity which can be filled with insulation. External wall insulation is applied to the outer face of a property’s walls improving the thermal efficiency of the walls significantly as well as giving the property a new and/or improved look.
Uninsulated solid walls lose even more heat than cavity walls, at a rate of around 45 per cent, meaning that for every £100 spent on heating an uninsulated solid wall property, something like £45 is escaping into the outside environment

Technical Information.
Heat will always flow from a warm area to a cold one, and in winter, when it is even colder outside, the heat will escape from your home into the surrounding air even quicker.
External wall insulation can significantly slow down the rate at which heat escapes, keeping as much of it inside your home as possible.
