Abstract
Bracing strips 7 are interposed between compressible strips 4, so-called laminate strips, of an insulating mat 1 in the form of a laminate mat with a carrier web 2, in order generally to impart compression resistance to the insulating mat 1. The compressible strips 4 normally consist of mineral fibers 6 of low compression resistance and are readily compressible parallel with the plane of the carrier web 2, while the bracing strips 7 consist of mineral fibers of higher compression strength and are substantially incompressible. Particularly good compression strength results from the fibers 8 of the bracing strips 7 also being orientated at right-angles to the carrier web 2. The resulting pressure-resistant laminate insulating mats 1 are suitable not only for the conventional fields of application of laminate mats but can also serve at the same time as a bracing since in many cases they offer superior qualities to those of supports or braces which consist of solid bodies.
