Notes:
- Values have been calculated using the limit state method described in the “European Recommendations for the Design of Sandwich Panels” (ECCS document No.115 2001), taking imposed loads, temperature and creep into account.
- For each value individual and combined load cases with appropriate load factors and temperatures have been considered. These are detailed under "Structural Performance" in Building Design Section
- The table is for medium and light coloured panels, as recommended by Kingspan for roofs.
- The following deflection limits have been used:
Downward loading L/200
Suction Loading L/150
- For intermediate values linear interpolation may be used.
- The actual wind suction load resisted by the panel is dependant on the number of fasteners used and the material of the purlin. The fastener calculation should be carried out in accordance with the appropriate standard For further advise please contact Kingspan envirocareTM Technical Services.
- The allowable steelwork tolerance between bearing planes of adjacent purlins is +/- 5mm.
- Load span tables for the panel specifications not shown are available from the Kingspan envirocareTM Technical Services
- FM approved panels spans must be limited to a maximum of 2 metres in single or double span condition
