Protan Cool Roof
A white roof surface with a high Solar Reflectance Index gives significantly lower temperatures in a compact roof construction compared with darker colours and thus contributes to transferring less heat to the actual building. This is a key characteristic in warm climates because it contributes to reducing the building's need for cooling, and considering that the building contributes to heating its surroundings, particularly in urban areas (« the urban heat island effect»).
The Cool Roof with a white colour is, naturally, more effective in warm and sunny regions than in cooler climates. It can, however, be useful to lay a white membrane in front of the intake of, for example, an air conditioning system.
The Cool Roof provides both immediate and more long-term saving in terms of the building's energy costs. The product can be installed mechanically or as a vacuum roof. Protan Cool Roof has been tested pursuant to ASTM C 1549-04 and ASTM C 1371-04a in accordance with approved methods from the Cool Roof Rating Council (CRRC).

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,
