FIRE-RESISTANT OR FIRE-RETARDANT MATERIAL, METHOD FOR MANUFACTURING A FIRE-RESISTANT OR FIRE-RETARDANT MATERIAL, CONSTRUCTION ELEMENT AT LEAST PARTIALLY COVERED WITH A FIRE-RESISTANT OR FIRE-RETARDANT MATERIAL

摘要

The invention relates to a fire-resistant or fire-retardant material, comprising: two layers of a sheet-like material arranged on each other, the layers being connected gas-tightly to each other along their peripheral zones by a peripheral seam, and a substance which is arranged between the two layers and which expands at a determined minimum temperature. The invention further relates to a method for manufacturing a fire-resistant or fire-retardant material. The invention also relates to a construction element at least partially covered with a fire-resistant or fire-retardant material according to the invention or a fire-resistant or fire-retardant material manufactured by performing the method according to the invention.
