Abstract (en)
The present invention relates to a cost effective and a relatively lightweight fire-retardant shutter for smoke redirection and damping applications in air ducts, buildings and building industry. In particular, it concerns a fire-retardant shutter comprising at least one layer of a corrugated fire-resistant material and an intumescent material, wherein the intumescent material is positioned at least partially inside the concave surfaces formed by the corrugations of the fire-resistant material.
