• Durability: must be able to withstand the horizontal and vertical loads. See Eurocodes and our technical
sheet to determine the maximum force on the curb. Consult your architect or engineering office.
• Deformation: maximum 5 mm at the maximum horizontal load on the curb. Ensure that there are enough
anchors for this provided on top of the curb. Consult your architect or engineering office.
Skylux does not guarantee curb stability as this is the responsibility of the client.
b. Dimensions
The barrel vault is made to customer specifications. It’s for this reason that the curb’s overall length and width
(roof covering included) must perfectly conform with the dimensions ordered at all points of the barrel vault. Look
for the narrowest and broadest spot* and measure the minimum and maximum overall width.
Permissible tolerances with respect to the size ordered:
Width: Min: -2 cm
Max: +1 cm
Length: ± 0,05 % (± 5 cm for a length of 100 m)
The barrel vault could possibly still be shortened in length on site, but try to avoid this.
Check the straightness* (±1 cm/5 m), parallelism* (±1 cm/5 m) and squareness (± 1°).
Check the agreed correct measurements of the curb in advance (overall sizes - including roof covering).
Also check whether the curbs run parallel in a row of two, verify the squareness and see whether the top is flat
and smooth. Clean it in advance, if necessary, and remove sawdust, irregularities, etc.
*
Tighten a rope on both sides of the curb (or use lasers). Find the average position of the curb edge to tighten the rope. This rope
will also be used later to mount the lateral profiles nicely aligned with each other.
Important: should one of these specifications fail to be met, then mounting must not take place. Should you
nevertheless assemble the unit, it may have an adverse effect on several different parameters (stability, air and
water tightness, etc.), thus rendering any guarantee null and void.
c. Glazing and arches
- The glazing panels are only clamped to allow the expansion and contraction as a function of fluctuations in
temperature. The system is designed to render any silicone or rubber seals between the aluminium and glazing
redundant (and even strongly discouraged).
- All profiles and glazing panels (with the exception of the end piece retainer sheets) are custom-made, pre-bent,
pre-drilled and screw thread tapped.
- Be careful with the exposed UV-protected top side of the sheets (glazing).
- As a last step, do not forget to remove the protective film from the glazing sheets.
d. Sealing
Install the roof cladding according to the manufacturer’s specifications. The curb must be clad up to the daylight
size. If the barrel vault is obstructed, meaning that it is adjacent to one or more walls, the connection must
be vertical and flat. This can be done by means of a lead flashing. Before assembling: clean, remove sawdust,
irregularities, etc.
