Insulating Concrete/Screeds

  • Lightweight concretes and screed made with expanded perlite and pumice reduce transferred of heat through floors and reduce construction weight.
  • A screed containing perlite can reduce thermal conductivity from 1.04 to between 0.15 and 0.25 w/m oC.
  • Standard concretes and screed have densities between 2000 and 2200 kg/m3, density of perlite concretes and screed is from 600 to 1050 kg/m3 which improves the thermal efficiency and also reduces the weight of the final structure.

Applications:

  • Lightweight concrete Roofs
  • Insulating Screeds
  • Sandwich construction
  • Fire resistant plaster mixes
  • Dry building mixtures
  • Manufacture of lightweight blacks and bricks for specialist construction
