Energy saving and environment

A natural volcanic mineral; light and non-combustible, it adds energy savings in insulating plasters and fills.

How to choose

  1. Choose grain size by application: 0–1.5 mm for insulating plaster, 0–3 mm for lightweight concrete and screed, 1–4 mm for loose fill.
  2. In perlite concrete keep cement below 200 kg/m³ and do not use poker vibrators, or the grains crush and insulation value drops.
  3. For high-temperature insulation (kilns, chimneys, refractory mortars) prefer coarse, low-density grades.
  4. Expanded perlite is very light, so freight is charged by volume. If you have an expansion plant, buying crude ore cuts transport cost substantially.
  5. For industrial grades, check the analysis: particle size (≤100 or ≤150 µm), loss on ignition ≤1 % and arsenic and lead limits for filter aids; low density and free flow matter most for cryogenic tank fill.

Description

Mixed with cement or gypsum, expanded perlite produces lightweight, insulating plaster, concrete and screed; on its own it is used as loose fill in lofts and wall cavities. Being non-combustible (class A1 material), it is also used to insulate kilns, fireplaces and tanks.

Because expanded perlite is bulky and light, freight costs are high over long distances. For distant markets we also look at expanding raw ore locally.
