Cavity Wall Insulation
What Is Cavity Wall Insulation?
Cavity wall insulation is a highly effective method of improving your home’s thermal performance by filling the space between your walls with a specialised insulating material. WeatherDry UK uses the Energystore Superbead system, an injected expanded polystyrene (EPS) bead bonded with adhesive, suitable for a wide range of cavity wall scenarios, including masonry, party walls, and timber frames.
How Does Cavity Wall Insulation Work?
The EPS beads are injected into the cavity, creating a continuous barrier that prevents heat loss while maintaining the wall’s ability to breathe. The system requires substantially fewer drill holes than other cavity fill products, allowing the installation to be completed quickly and efficiently with minimal disruption.
Key features include:
-
Excellent thermal properties: Keeps your home warmer and reduces energy bills
-
Water repellent: Prevents moisture penetration and damp issues
-
Durable and hygienic: EPS beads do not rot, decay, or attract insects, parasites, or rodents
-
Breathable: Naturally occurring gaps between beads allow water to drain safely without creating damp inside the walls
Why Choose the Energystore Superbead System by Weather Dry?
The system combines price and performance, providing a high-quality alternative to traditional mineral fibre insulation. It is fully backed by:
-
Insurance-backed guarantee from Quality Mark Protection.
-
25-year manufacturer warranty.
This ensures long-term protection and peace of mind for your property.
