Important: Check that the roofcurb height is suffi cient to respect
the minimum sealing height required according to local regulations
(example: 150 mm minimum sealing height in France according
to DTU). To do this, check that the "D" dimension of the roofcurb
exceeds the thickness of the cladding plus the insulation plus the
minimum sealing distance required.
