Microporous insulation is a composite material in the form of compacted powder or fibers with an average interconnecting pore size comparable to or below the mean free path of air molecules at standard atmospheric pressure. Microporous insulation may contain opacifiers to reduce the amount of radiant heat transmitted.
The resulting blend of materials and pore structure produces a thermal insulation with extremely low thermal conductivity across a broad temperature range. The Microporous core material is completely inorganic, making it non-combustible and suitable for passive fire protection applications.
