Roof insulating board made of rockwool has two large, parallel surfaces, connected via cut surfaces and two longitudinal planes

摘要

The board features a maximum variance of +0.5 - 1 mm in width and/or maximum oblique angle of 0.4 - 1 mm of the cut planes (4) in relation to the oblong planes (5). The cut planes and/or oblong planes are equipped with recesses (20) and/or protuberances (19) so that adjacent cut planes engage with each other. The recesses and/or protuberances enable adjacent oblong planes and/or cut planes to tilt in relation to each other to at least a limited degree. A separate description is given of the associated installation for processing the board.
