CLASSES OF EXTERNAL FIRE PERFORMANCE FOR DOUBLE SKIN METAL FACED SANDWICH PANELS FOR ROOFS

Panels with a profiled external metal facing incorporating:

  • minimum thickness 0,4 mm for facings of steel and stainless steel;

  • minimum thickness 0,9 mm for facings of aluminium;

  • at each longitudinal joint between two panels an overlap of the external metal facing extending across the crown and a minimum 15 mm down the opposite face of the crown, or a metal cover cap completely covering the joint crown, or a raised standing metal seam along the joint;

  • at each transverse joint between two panels an overlap of the external metal facing of at least 75 mm;

  • a protective weather coating comprising a liquid applied PVC paint of maximum nominal dry film thickness 0,200 mm, a PCS of not greater than 8,0 MJ/m2 and a maximum dry mass of 300 g/m2;

    or any thin paint coating less than the above;

  • minimum reaction to fire classification of D-s3, d0 without edge protection in accordance with EN 13501-1.

Class as provided for in the table of the Annex to Decision 2001/671/EC.

Symbols used: PUR = polyurethane; MW = mineral wool; PVC = polyvinyl chloride; PCS = gross calorific potential.
