ABSTRACT:
A sub-roof for roofs with roofing boards consisting of a plurality rectangular insulating boards (1) overlapping each other in direction of the slope of the roof. Each insulating board has a parallel plane central section (3), integral with a wedge-shaped board section (2) on the ridge side and a wedge-shaped board section (4) on the eaves side, the thickness of which increases towards the middle of the board. The thickness of the board sections (2 and 4) on the ridge side and on the eaves side at their edge towards the central board section (3) is at least equal to the thickness of said central board portion (3) and, when thicker boards are used, reaches said thickness after going through a step (11 and 12). The insulating boards (1) are placed so that they constitute an offset double or multiple covering. Due to the wedge-shaped multiple overlap the rows of insulating boards can be shifted within the longitudinal direction, for example, to adapt to different batten intervals or spacing, whereby the effective insulating layer thickness of the sub-roof does not change noticeably and tightness is not affected.
