Prior inspection
Curb
Before installing the barrel vault, the customer must provide a solid timber or metal curb that must be non-
deformable (can be reinforced with tie rods if necessary). The maximum roof pitch is 5°.
Before starting the
installation, please check if following specifications are met:
• Material: wood / galvanised steel min. 3 mm thick
In case of a concrete curb, you first need to anchor a
wooden bar of at least 44 mm thick into the concrete
with suitable countersunk screws. Cover the wooden bar
with the roof covering too. Strictly respect the determined sizes.
• Min. height (above the finished roof): 150 mm
• Min. finished thickness: 65 mm
• Max. finished thickness: 80 mm
• The upper flange and the curb must be equally thick. The
insulation cannot protrude or be thinner than the upper flange.
• Upper flanges of all 4 sides must be on the same surface!
• The curb construction must be free all-round: none of the curbs
may continue at the angle of the lateral side and the front side.
• Pitch of the upper flange:
- barrel vault crosswise on the roof ridge: perpendicular to the roof surface (follow the roof
pitch)
- barrel vault parallel to the roof ridge, 2 possibilities:
o horizontal: both sides must be equally high and levelled (the lowest side of the curb must rise
higher above the roof surface than the highest side). The upper flange can slightly lean
outwards, max. 2°.
o It’s also possible to follow the roof pitch (up to max. 5°).
• Sturdiness: must be able to resist the horizontal and vertical load. See Eurocodes and our technical file for the
determination of the maximum forces on the curb. If any doubt, please consult your architect or research
bureau.
• Deformation: max. 5 mm in case of maximum horizontal load on the curb. Provide enough tie rods at the top of
the curb. If any doubt, please consult your architect or research bureau.
