<p>1. Sheet of insulating material, in particular of mineral fibre felt, comprising a facing which is glued to it as a barrier layer (2) and means for fixing the sheet to elements which form the boundaries to the edges, such as roof rafters, between which the layer of insulating material (1) may be installed under lateral pressure, at least one cut (7 or 8) being made by the manufacturer in the region of the lateral edge of the layer of insulating material in a direction parallel to said edge and without cutting into the facing, so as to form a modular edge strip (4 or 5) which can easily be removed to facilitate adapting the width of the layer of insulating material (1) to the particular requirements of the installation, characterised in that the cut (7 or 8) passes through the whole height of the layer of insulating material (1), the cut surfaces of the cut (7 or 8) are juxtaposed against one another, and the layer of adhesive (9) between the sheet of facing (2) and the layer of insulating material (1) is also provided on the edge strip (4 or 5) which is separated by the cut.</p> |
