Cavity wall insulation is a simple way to make your home more energy efficient. The process involves blowing or injecting insulation material into the empty space (cavity) between the inner and outer walls. This helps prevent heat loss, reduces energy bills and improves the comfort of your home. Here, we explain step by step how cavity wall insulation works and what the benefits are.
Cavity wall insulation is installed in 5 steps:
1. Inspection
2. Preparation
3. Blowing or injecting the insulation material
4. Sealing the drill holes
5. Final inspection
1. Inspection: Before the insulation is installed, an expert carries out a thorough inspection of the cavity wall. This includes checking whether the cavity is suitable for insulation and identifying any potential obstacles, such as debris or moisture problems. An endoscope may be used to inspect the inside of the cavity.
2. Preparation: Small holes are drilled into the mortar joints of the external wall. The diameter of the holes depends on the width of the joints. These holes are drilled in a prescribed pattern and evenly distributed across the wall to ensure that the insulation material can be applied throughout the entire cavity.
3. Blowing or injecting the insulation material: The insulation material is blown or injected into the cavity through the drilled holes using specialist equipment. Different materials can be used, including polyurethane foam, mineral wool, rock wool or insulation beads. The material is applied under controlled pressure to ensure an even distribution throughout the cavity. This helps fill the entire cavity and minimise air gaps and thermal bridges.
4. Sealing the drill holes: Once the insulation material has been installed, the drill holes are carefully sealed using matching mortar. This restores the appearance of the external wall and helps prevent moisture and dirt from entering.
5. Final inspection: A final inspection is carried out to confirm that the insulation has been installed correctly. This includes checking that the cavity has been properly filled and that all drill holes have been securely sealed.
