Cavity Wall Insulation
The external wall of a house is constructed of two brick or block walls with a gap (or cavity) of at least 50mm between, joined by metal ties. As much as 35% of all heat loss from an average house escapes from the walls.
Cavity wall insulation is normally applied from the outside. A trained technician drills small holes in the external wall using a pattern specified within the industry technical standards.
The cavity wall insulation material is then pumped into the holes using a blowing machine; this has an automatic cut-out (like a petrol pump) 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.
The Cavity Insulation Guarantee Agency (CIGA) provides an independent 25 year Guarantee for cavity wall insulation undertaken by approved installers. It is an entirely independent agency.
The period of guarantee is 25 years from the date of installation. CIGA guarantees that any defect in materials or workmanship in connection with the installation by an approved member installer shall be rectified without charge to the customer.

Loft Insulation
As much as 25% of all the heat lost from an average home escapes through the roof. Over 1 million homes have no loft insulation at all.
Most UK houses have some loft insulation, but the majority with 100mm (4”) or less should be substantially topped-up to around 270mm (11”), the requirement for new homes. The loft insulation material is rolled between the joists and may then be applied in a second layer across the joists to avoid cold-bridging.
