Protan Cool Roof

Protan Cool Roof is a roof system where a white membrane is used when laying exposed roofing with a documented high Solar Reflectance Index. It also has high thermal emissions, which is a measurement of how efficiently heat is radiated as thermal radiation to the surroundings.

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,

Contact Protan for an overview of all relevant fire classifications.

We have solutions for BROOF(t1),BROOF(t2), BROOF(t3) and BROOF(t4) classifications for most relevant surfaces.

Protan Cool Roofs

Protan Cool Roof is a system that uses a white membrane with a documented high solar reflectance index (SRI) – and less need for cooling.

Protan Solar Roofs

Protan Solar Roof is a concept that paves the way for photovoltaic or thermal panels to be installed on roofs covered with Protan membrane.

Protan Design Roofs

Our flexible solutions help to enhance the architecture, as well as the building's appearance and identity. The roof helps to send a message about the building's purpose, character and relationship with the surroundings.
