FIELD: construction. ^ SUBSTANCE: primary element for heat and sound insulation panel is made of mineral wool or asbestos mat in the form of parallelepiped having two main sides and longitudinal edges and consisting of multiple fibers. Fibers are impregnated with binder. Primary element comprises relief zone at the level of at least one of its longitudinal edges. Relief zone is arranged with the possibility of laying bent part of cladding coat on it, at that the coating is tightly adjacent to its surface. Relief zone is arranged in part of mat thickness next to the first main side of mat. Relief zone limits two neighbouring zones. Cladding coating may be fixed to the first main side of mat, which is inverted outside from closed space. Cladding surface is not flanged to the second main side of mat, which is directed inside closed space. ^ EFFECT: provision of fire safety barrier, heat and sound insulation and resistance to breakout power. ^ 28 cl, 7 dwg |
