Our insulation blocks are designed to improve the thermal performance of walls and floors in residential and commercial builds. Lightweight and easy to work with, they provide excellent U-value contributions and help reduce heat loss through the building envelope. Ideal for cavity walls, internal partitions, and below-DPC applications, these aerated concrete blocks offer a balance of strength, thermal insulation, and fire resistance. They’re commonly used in new builds and retrofit projects where building regulations require enhanced energy efficiency.
We stock trusted brands including Celcon, Mannok and Thermalite, available in a range of sizes and thermal conductivity ratings. Need mortar or accessories to complete the job? Explore our Cement & Aggregates and Damp Proofing sections.
