Fine texture blocks are either left unplastered or painted for use in internal walls.


  • Available in High compressive strength
  • Class A1 – Fire resistance
  • Excellent sound insulation
  • Long term durability
  • Sustainable production process
  • Low thermal conductivity and high thermal capacity


  • Extensive range of solid and hollow blocks
  • Standard sizes – metric 450mm and modular 400mm ranges
  • Wide choice of accessory products
  • Produced nationwide
  • Cost effective


Typical application for fine texture blocks include churches, schools, sports centres, office, factories etc.
