Building Protection Regupol® resist FH
Flame resistant membrane protection on flat roofs
The Regupol® resist FH building protection sheet is the new product from BSW to protect membranes and insulation, and to reduce the fire load on flat roofs. The flame-retardant equipment makes the sheets made of PUR-bound rubber granulates resistant against flying sparks and radiant heat.
The fire resistance rating is considerably enhanced from a fire protection point of view. Regupol® resist FH insulation and building protection with a thickness of 8 mm is classified as BRoof (t1) and therefore considered to be hard roofing.
Under certain circumstances, Regupol® resist FH insulation and building protection hence considerably reduces the use of gravel filling and tile material, and hence the entire roof live load. This is a crucial advantage, particularly in the field of roof restoration.
Regupol® resist FH is important as a complement to membrane products which do not themselves meet the requirements of hard roofing.
Insulation and Building Protection with the general appraisal certificate no. P-2010-B-4365-01
The general appraisal certificate confirms that Regupol® resist FH is resistant to flying sparks and radiant heat according to DIN V ENV 1187.
General appraisal certificates are solely issued by the test centres accredited to do so by the German Institute for Civil Engineering (DIBt), in this case MPA Dresden.
The test was performed on both standard old roof varieties, FPO and bitumen membranes.
Regupol® resist FH considerably reduces the fire load.
One square metre of conventional building protection has an energy content of 47.5 kWh or 171,000 kilojoules. This equals the heating value of 4.75 litres of heating oil.
Regupol® resist FH insulation and building protection greatly helps to prevent the outbreak of fire and its spreading to adjacent roofs.
