Cavity Wall Insulation – How To Measure Its Effectiveness?

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 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 wall insulation can be measured following another key aspect: the R-value. The R-value of the insulation materials reveals the 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 1000 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.

Sprayed Foam Home Insulation – Turn Your Home Energy Smart

Sprayed Foam home insulation product is a foam based insulation product that is applied to insulating cavity walls, floors or roofs. As this insulation product is sprayed to the openings in the area, it expands to create the insulation barrier. This foam insulation material is a chemical insulation product being made of polyurethane. The polyurethane comprises a chemical formulation of multi-ingredient chemicals. Apart from this main multi-ingredient chemical composition, sprayed foam insulation also contains other additives like fire retardants as well as colours too, often.

Apart from providing home insulation, spray foam based insulation materials are good air sealing. The air sealing treatment can be applied to several places of the house where small openings allow air passing such as cavities in the wall, cavities in the ceilings. The foam product can be sprayed using a special equipment to the targeted holes in the walls or ceilings. On spraying, the chemical formulation swells to cover up all the corners and crannies in the area. While application, the spare materials must be scraped off the wall pr other spaces to form uniform cavity insulation and ensure an effective air sealing guard to prevent air and heat conduct.

Advantages of Spray Foam Home Insulation
There are several advantages of sprayed foam home insulation materials. First of all, sprayed foam home insulation is an easy to apply insulation option that fills up the targeted nooks in the walls completely providing it air sealing protection to stop further air passing. This insulation material is known to reduce air infiltration and air circulation that allows heat transfer through gaps in the walls. The sprayed foam insulation also acts as a vapour barrier. However, the installer must consult with the local building department whether the building needs a vapour barrier. As the foam materials expand well in the tight areas, it makes a good insulation for steel framing outlets or forming insulation around outlets.

Apart from polyurethane chemical composition, the spray foam home insulation products can be combined with other insulation materials such as fibreglass batt in order to reduce cost. The layer 1000 of foam based insulation mixed with other materials performs better air sealing thus turning the home more energy smart within lesser budget. Some home insulation contractors use this foam product as a 1′ inch layer of closed cell foam and then tops the layer with fibreglass batt insulation for increasing performance of the insulation.
