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 roof plus the insulation plus the minimum
sealing distance required.
