Cavity Wall Insulation
In cavity construction, the external walls of a house are constructed of 2 brick or block walls with a gap of at least 50mm between them. These 2 walls are joined by metal wall ties.
Cavity Wall Insulation is normally applied from the outside. Trained technicians drill small holes in the external wall using a practice specified by the industry technical standards.
The insulation material is then pumped into the holes using a blowing machine, this has an automatic cut off that actuates when the wall area is full. The holes are then made good to match the existing finish as closely as possible. Once installed the Cavity Wall Insulation requires no maintenance and will last for the lifetime of the building.
By insulating your home you could prevent the emission of around 135 tonnes or more of C02 pollution during your lifetime. The average saving per year by insulating your walls can be between and 25 and 35% of your fuel bills. As part of the carbon emissions reduction target 2008-2011 (cert) the government has instructed fuel suppliers to offer grants for insulation to reduce energy use in the home. 3 million homes will have their cavity walls and lofts insulated under this scheme.
Any householder who is over 70 or in receipt of certain income related benefits or tax credits will be entitled to free insulation. Everyone else who owns their own home or rents from private landlords will be eligible for a substantial grant towards the cost of insulation. Access to these grants is available directly from CavityTech. It is not necessary to change your fuel supplier in order to qualify, the grants are not means tested and they do not have to be repaid.
All Cavity Wall Installations are covered by the Cavity Insulation Guarantee Agency (CIGA) who provide a 25 year independent guarantee for Cavity Wall Insulation which is undertaken by approved installers. It is an independent agency with its own administration and secretaire. CavityTech are members of CIGA, the national insulation association and the British Board of Agrement.
