Cut your heating costs

Much of the heat in your home is lost through its walls. At RSI, we provide first-rate cavity wall insulation services that can reduce your heating costs by up to 35%. This in turn reduces the CO2 produced from your household and can save over a tonne of CO2 over the average life of a building. During the insulation process, we fill the gap between the inner and outer skins of brick with insulating material. This reduces the amount of heat that is lost through the walls. For cavity wall insulation, we use whitewool cavity wall insulation or bonded bead insulation systems, depending on the job at hand. The experienced staff at RSI can conduct an inspection before the work is started to determine whether your building is suitable for cavity wall insulation.
