Isoperl 5

the ecological and physical alternative

Isoperl 5

Isoperl® - 5 is a grained, heat and sound insulating levelling bulk on a  Perlite-basis for levelling masses under mastic asphalt and wet screed.

Protects against heat / cold / noise and fire

  • Not self-bearing dry fillings for interiors in new and old buildings
  • Thermal insulation for floors and ceilings
  • Step noise dampening under floating screeds 


  • Does not attack other materials, especially metal
  • Height levelling without cutting and waste

Natural advantages

  • Anorganic, because it is a mineral
  • Does not rot or shrink
  • Safe against pests
  • Chemically neutral
  • Healthy construction

Isoperl® -2 and Isoperl® -5 are frequently used as substrates for liquids, as for white products such as milk powder products and urea, and are also approved for organic and ecological feeds.

Isoperl® is also used in formulas in which you want to achieve a good anti-caking effect (no clumps) with small quantities of additives.  Due to the structure of Isoperl® it is easy to link and is therefore used as a filler in rubber processing (toothbrushes with rubber ribs with Isoperl®), abrasion coats, abrasion pastes (toothpaste for professional teeth cleaning) and in the paper industry etc.
