100MM MANNOK AERATED BLOCKS

The Mannok Aircrete Standard thermal block is a high-performance autoclaved aerated concrete (AAC) block engineered to combine excellent thermal performance with reliable strength and ease of installation. These lightweight AAC blocks are ideal for a wide range of on-site applications, including external walls, party wall construction, internal partitions, and rising foundation walls — offering a strong balance of thermal efficiency and structural capability.

Manufactured using advanced AAC processes, this block delivers consistent quality, low density, and superior insulation compared with traditional dense concrete blocks — helping you achieve improved energy efficiency and reduced heat loss in your projects.

Key Features

• Lightweight autoclaved aerated concrete (AAC) construction for easy handling and installation

• Strong thermal performance with a low thermal conductivity value of ~0.17 W/m·K, helping improve wall U-values
