H+H Jumbo Bloks are large-format aircrete blocks designed for use in thin layer construction to enhance build speed on site.

As few as 6.3 blocks are required to complete 1m² of walling.

Features and Benefits

  • Large-format blocks reduce the number of units required per square metre

  • Compatible with thin layer construction for faster build times

  • Multiple compressive strength options: 2.9N/mm², 3.6N/mm², 7.3N/mm², 9.7N/mm²

  • Thermal conductivity values: 0.11W/mK, 0.15W/mK, 0.18W/mK

  • Block densities: 460kg/m³, 600kg/m³, 730kg/m³

Applications

  • Inner leaf of cavity walls

  • External leaf of cavity walls

  • Separating walls

  • Flanking walls

  • Partitions

  • Multi-storey buildings
