Celcon High Strength Grade blocks are made from aircrete and designed for use where higher compressive strength is needed, such as in multi-storey buildings and foundations. Key features include a compressive strength of 7.3N/mm², thermal conductivity of 0.18 W/mK, and density of 730kg/m³. Available in widths from 100 to 355mm.

  • High strength aircrete block for structural applications

  • Compressive strength of 7.3N/mm² supports heavy loads

  • Suitable for use below ground level and in multi-storey construction

  • Thermal conductivity of 0.18 W/mK aids energy efficiency

  • Range of widths from 100mm to 355mm for design flexibility

  • Lightweight for easier handling and installation

Applications

  • Foundations and below ground level (DPC)

  • Multi-storey buildings

  • Inner and external leaf of cavity walls

  • Solid and separating walls

  • Flanking walls

  • Beam and block floors
