Cavity wall insulation offers an efficient means of reducing energy consumption and mitigating carbon emissions. To implement this method, holes are drilled approximately 1.5 meters apart from the joints in walls with a cavity.
Subsequently, insulating material is injected to fill the cavity, with each hole being injected from the bottom. Typically, cavity wall insulation can be completed within two hours, although the duration may fluctuate depending on the wall's size and the inner cavity. For properties with cavities in their walls, the government provides grants for cavity wall insulation, recognizing the potential hazards involved. This insulation serves as a barrier between the walls, minimizing heat loss. The cost of cavity insulation can vary based on various factors and conditions.
