A visible terrace membrane designed for exposed terraces and balconies where an aesthetic, strong, durable and safe surface for pedestrian traffic is required. The system is well suited where there are low door steps that require low profile solutions and low weight and where there is a desire for easy cleaning.

FIRE TESTING REQUIREMENTS FOR FITTING EXPOSED ROOFS ON A BUILDING.
ABOUT THE RULES FOR FIRE RATINGS OF ROOF MEMBRANES IN EUROPE:
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,
BROOF(t3) in accordance with EN13501-5 and ENV 1187 part 3, or
BROOF(t4) in accordance with EN13501-5 and ENV 1187 part 4,
