Cenolite C

Cenolite C perlite microspheres made from crude perlite are natural amorphous siliceous glass bubbles containing a multi-celluar core with nonporous smooth surface. Cenolite is an excellent replacement for many expensive light weight fillers.



  • Cost effective
  • Fire resistance
  • Outstanding weight reduction
  • Superior thermal insulation
  • Noise absorption and insulation
