Cavity wall insulation improves the energy efficiency of homes with cavity walls, which are two layer external walls with a small gap between them.
Cavity walls are very common in UK homes that were built after the 1920s and were initially designed to reduce dampness, but they can also let a lot of heat out. Insulating cavity walls keeps the heat in, reduces outside noise, and keeps energy bills to a minimum.
Insulation consists of small holes being drilled in the outside walls, before the injection of insulation material into the cavity; the process is relatively quick, cavity wall insulation typically takes a few hours.
While an energy-efficient method for many houses, not all homes are suitable for cavity wall insulation, such as solid walls with no cavities. If your home has existing damp problems and poor brickwork, trapping moisture can worsen these issues.
Professional insulation is key for completing the job effectively.
