Abstract (en)
[origin: EP0848131A1] The sections are formed by hollow sections of aluminium or similar material with an enclosed outer (11) and inner (12) chamber. These contain a fire-resistant material, connected by at least two webs (13,14) with apertures (15) to reduce heat transfer. The webs form a spatial lattice structured, reducing the proportion of material to e.g. 5%, so that the maximum surface temperatures allowed by testing standards after a predetermined time are not exceeded. Preferably, the apertures are in the form of slots, such that slots in one web are displaced by half a slot length with respect to slots in the other web.
