Method of installing a mineral fibre material provided in roll form, a mineral fibre strip suitable for carrying out the method and a method of producing the mineral fibre strip

Abstract

From a mineral fibre strip supplied in roll form, portions (L) are cut off, the length of which corresponds to the width of a rafter area between rafters plus an oversize designed to produce a clamping effect. Formed in this way, the mineral fibre panels are so inserted into the rafter area that the lateral edges of the mineral fibre strip form the top edge and the bottom edge of the panels. In this way, it is possible to achieve virtually completely wastage-free roof insulation even when the distances between the roof rafters vary considerably, and it is possible to work with material of one uniform and considerable width which is supplied in the form of rolls. By reason of the considerable width of the mineral fibre strip, insulation of one rafter area over its entire length requires only a few mineral fibre panels, with few joints being produced. To facilitate guidance of the cut for separating the portions (L), it is possible to provide on one side of the mineral fiber strip marking lines which can, during production, be generated by a co-rotating roller having linear heated zones.
