There are many reasons for choosing Insulated Homes, a maintenance free home, reduced fuel bills, reduced noise intrusion, to stabilise your home from further deterioration or to increase the aesthetics and value either for, selling purposes or just to enjoy the benefits that Insulated Homes provides.
Government studies have been carried out on many methods of insulation both internal and external. These Governmental studies have shown that an exterior insulation system can radically improve the thermal insulation properties of your home by reducing heat loss with saving of up to 30% on fuel bills.
These studies have been reported by the Good Practice Guide no. 293 covering, External insulation systems for walls of dwellings.
In summary they state; EI is often the best option for upgrading the thermal performance of existing buildings, and should be considered in refurbishment strategies.
EI can simplify construction and achieve environmentally significant thermal performance in new build projects.
Large amounts of insulation can be used with EI, while easily avoiding thermal bridging. The buildings’ structure will be protected and internal thermal mass can be achieved to moderate internal temperature fluctuations.
In the Governments comparison of; different wall insulation methods in refurbishment projects between; Insulated cavity walls, Internal lining and External insulation, the External insulation system came out by far the most efficient in; Upgraded appearance, potential for thermal improvement and structural improvement.
