Profile contg. fireproofing insert - comprising foam body coated with thermally expansible material, is highly effective and very simple and inexpensive to produce

摘要

In a fireproof profile, pref. a hollow metal body (e.g. a door frame, door, parapet element or the like) with a fireproof insert, the novelty is that the insert comprises a foam body (1) coated with a thermally expansible material (2). The thermally expansible material may be an intamescent material based on urea deriv.-ammonium polyphosphate-polyacetate. ADVANTAGE - The fireproof insulation is highly effective and is extremely simple and inexpensive to produce.
