Fastening arrangement for rigid heat insulation plates between roof rafters

摘要

The arrangement has a deformation part (D) which can be inserted between the side faces (20,27) of rafters (8) and the insulation plate (23). In deformation part extends over the length of the insulation plate. On insertion between the plate and the rafters the deformation part is deformable to create a clamping force between the rafters and the plate. The deformation part (1) consists of a plastic strip (2) with projection platelets (4) forming air channels (5).
