The cavity wall insulation is strongly advocated by the Government for all existing general buildings if they are built in or after 1935 onwards till 1989. From 1989 onwards, buildings were insulated according to the then building regulations. Houses built during the span between 1935 to 1989 following regulations had such spaces in the walls for air passage. Currently, such openings in the walls act as a catalyst to heat exit and entry of cold air inside leading people  Free insulation grant depend hugely upon the energy operated heating system. These heaters produce carbon dioxide based heat to maintain indoor climate and hence, increase CO2 emission in the environment. More carbon dioxide gases emit; more our environment is threatened by the global warming risks. To fill these cavities, a cavity wall insulation measure has been the ideal home improvement measures.

Cavity wall insulation is a secure and approved method of improving energy efficiency. Once fitted to the targeted space, this home insulation process renders permanent insulation solution that continues showing effects without a recurring maintenance. Thus, once you treat your walls by filling insulation to gaps between two thin layers of walls, the insulation effects will last for the life of your house.

The efficacy of wall insulation has been confirmed by the government Building Research Establishment. However, the degree of effectiveness of cavity wall insulation procedure is even higher if the insulation project has been completed by a professional installer. The approval and guarantee of the Cavity Insulation Guarantee Agency (CIGA) for 25 years on a wall insulation installation done by a registered installation contractor is a good way to ensure successful installation and effectiveness of cavity wall installation.

Apart from a seal of approval and certification on the insulation of the trusted agencies and the government, the efficacy of cavity insulation can be measured following another key aspect: the R-value. The R-value of the insulation materials reveals the  Free insulation grant capability of resisting heat transfer while 'R' stands for 'resistance'. The higher the value, the better insulation effects a material has. Before you choose a rigid foam, rolls or batts, fibreglass, cellulose, rock wool, foam-in-place or blown-in insulation - check out the R-value of the insulation materials for cavity wall insulation, collect R-value related facts on an insulation product.
