Definitions

the invention relates to multi-wall sheets made of polycarbonate for hard roofing of buildings or parts of buildings.
Essential criteria for passing the test are that on the surface or inside, destroyed surfaces do not exceed a defined size, no liquid, burning parts drip down the roof edge, no flames occur on the underside of the roof, no parts burn off or glow and that the roof remains closed so that no burning or smoldering parts can fall through.
DIN 4102 Part 7 and provide protection against secondary fire are approved as roofing of buildings or parts of buildings. Exemptions are only granted if there is no significant risk from the risk of secondary fires. This can, for example be the case for buildings or parts of buildings that are usually not entered by people and do not contain any highly flammable substances, or for roofs of small size where evasion from secondary fires is easily possible without danger.
Preferred dimensions for the thickness of the belt surfaces are 3 to 8 mm, particularly preferred are 3 to 4 mm.
Favorable dimensions for the thickness of the webs are 2.5 to 6 mm, 3 to 4 mm are particularly preferred.
Preferred web spacings are 20 to 40 mm.
the preferred plate height is 40 to 60 mm.
