Insulation Imerys expanded perlites are ideal filler insulators

Imerys expanded perlites contain countless air alveolus, making them extremely valuable lightweight insulators and fire-proofers in buildings.

Used as loose-fill insulation in roofs, floors and cavity walls, Imerys expanded perlites provide:

  • Optimal insulation
  • Excellent sound-proofing
  • Non flammability and fire-proofing
  • Durability: expanded perlite does not degrade or alter unlike most chemical agents
  • Inertness: perlite is inert and non toxic
  • Ease-of-use: perlite is easy to use, quick and clean
  • Re-usability: perlite beads can be recycled and used again


Expanded perlites are ideal for:

  • Cavity walls
  • Block fillers
  • Outer fillers and coatings
  • Subfloors
  • Passive fire protection
