US 3,940,526 A · Braced insulating element and method for its manufacture

Abstract

The invention relates to insulating elements particularly intended for use as a supporting core material in wall structures and the like, e.g. of the sandwich type. The insulating element consists of an insulating body of a non-supporting material such as mineral wool, which is intersected by a plurality of parallel, relatively thin sheet-formed bracing members of a stiffer material, such as polyester, polyethylene or the like, imparting to the element improved rigidity in one or more directions. The invention also relates to a beneficial method of producing such insulating elements, the method mainly comprising placing mats of the non-supporting insulating material in layers with intermediate coatings of the stiffer bracing material, and then cutting or dividing the assembled layers into slices with a thickness corresponding to the desired thickness of the insulation.

Dependent claims

A braced insulating element, particularly for use as a core material in a wall structure, said element comprising:

a first plurality of parallelly spaced bracing members;
a second plurality of parallelly spaced bracing members;
said first and second pluralities of bracing members extending orthogonally and intersecting each other to form therebetween a plurality of closed quadrangular cells;
each of said cells being filled by a building insulating material having low strength properties;
said bracing members being rigid in directions of the respective planes thereof and individually flexible in directions perpendicular to said respective planes;
said bracing members being continuously bonded to the respective adjacent insulating material;
said element having a pair of major surfaces extending in planes perpendicular to said planes of said bracing members, said major surfaces being formed substantially by said insulating material;
and
said element having plural edge surfaces extending perpendicular to said major surfaces, each of said edge surfaces being formed by a bracing member.
