Are you tired of drafty walls and skyrocketing heating bills? No worries! You can now improve your home’s energy efficiency with cavity wall insulation at absolutely zero cost with Prsima Services. The UK government offers grants that cover 100% of the insulation cost, helping eligible households save money, reduce CO2 emissions, and enjoy a warmer home during winter.
Understanding Cavity Wall Insulation
A cavity wall consists of two layers with a gap (or cavity) in between. Typically, the outer layer is made of bricks, while the inner layer can be bricks or concrete blocks.
- Homes built before 1929 are more likely to have solid walls—a single, thick brick or stone layer.
- Homes built after 1929 likely have cavity walls.
To determine whether your home has cavity walls, check the external brickwork. Cavity walls have a uniform brick pattern, while solid walls have alternating long and short bricks.
How Cavity Wall Insulation Works
Insulating cavity walls involves filling the empty space between the inner and outer walls with special insulating material. This process significantly reduces heat loss, making your home more energy-efficient and comfortable, especially in extreme weather conditions.
Materials Used for Cavity Wall Insulation
A professional installer drills small holes (18-25mm deep) into your home’s external walls and injects insulation materials such as:
✅ Polystyrene Beads – Highly efficient, durable, and water-resistant.
✅ Mineral Wool – Excellent for thermal and sound insulation.
Polyurethane Foam – Ideal for narrow or uneven cavities, although more expensive.
Since cavity wall insulation requires specialized techniques, it must be installed by certified professionals to ensure safety and effectiveness.
