VERMOFLEX
VERMOFLEX is a heat-expanding fireproof sheet that is made by mixing a heat-expandable inorganic material and small amounts of organic and inorganic binders with alkali earth silicate (AES) wool, and then manufacturing it into a sheet form. Its thickness expands by about three-fold when heated (when heated without a load).
