Warnings and safety
See p. 17 of these instructions.
Prior inspection
a. Curb
Before the barrel vault can be mounted, the customer must provide a sufficiently strong curb that must retain its
shape (if necessary, reinforced with tie beams) and with roof covering. To guarantee stability, a calculation must be
made by an architect or engineering office. The maximum roof pitch is 5°.
Before getting started with mounting,
check whether the following specifications have been met:
• Material: wood / galvanized steel min. thickness of 3 mm (*)
If the curb is in concrete, a wooden batten of at least 48 x 60 mm must be firmly anchored into the
concrete with countersunk and appropriate screws in advance. The wooden batten must also be covered
with roof covering. The agreed dimensions must be strictly observed.
• Height above finished roof: min. 200 mm
• Min. finished thickness: 65 mm
• Max. finished thickness: 100 mm
• The top flange and the curb must share the same thickness. Insulation may not protrude or be thinner than
the top flange.
• The upper flanges on each of the 4 sides must be on the same plane!
• Curb construction must be unobstructed on all sides: neither of the two curbs may go further at the
corner of the longitudinal side and on the end side of the curb.
Flat curb:
(*) to be calculated depending on the lateral forces
• Slope top flange:
- barrel vault at right angles to the roof ridge: perpendicular to the roof surface (follow roof pitch)
- barrel vault parallel to the roof ridge, 2 options:
o Horizontally: both sides must be of the same height, levelled (i.e. lower side of the curb must
protrude higher above the roof surface than the uppermost side). The top flange may protrude
slightly, up to a max. of 2°.
o It’s also possible to follow the roof pitch (up to max. 5°).
