Airborne fire tests of roof membranes for rating in Europe are carried out according to the test methods prEN*)1187. This is divided into four parts:

  • prEN1187 part 1,  known as the German fire test
  • prEN1187 part 2,  known as the Nordic fire test
  • prEN1187 part 3,  known as the French fire test
  • prEN1187 part 4,  known as the British fire test

*) prEN, where 'pr' means 'Preliminary', E-European and N-Norm. Alternatively, 'ENV' is also used, where 'V' stands for  “Vornorm”.

It is up to the authorities of a country to decide which of the four parts/methods will be accepted. After satisfactory testing, the roof membrane can be classified in accordance with EN13501-5 for the applicable surface it was tested on and receives the classification:

  • BROOF(t1) in accordance with EN13501-5 and ENV 1187 part 1,
  • BROOF(t2) in accordance with EN13501-5 and ENV 1187 part 2,

Protan standard overlap system

The Protan Standard Overlap System with mechanical fastening can be installed on all types of substrate, and used on both new build and renovation projects.

Protan adhered roof system

Fully adhered solutions can be appropriate where perforation of the vapour control layer is undesirable or the substrate makes mechanical fastening difficult or impossible.

Protan vacuum roof system

Protan Vacuum Roofing is a unique system that does not require fasteners or adhesives to be used on the roof surface. The wind forces create a vacuum effect that sucks the membrane firmly onto the roof structure. The windier it is, the better the system works.
