Does Adek Aluminium Decking System meet the revised fire regulations for the high-rise buildings?
Yes, it is non-combustible..
It is now a legal requirement for any building materials incorporated into the envelope of a high rise building exceeding 18 in height to be non-combustible.
All Adek profiles have undergone independent third-party testing to BS EN 13501-1: 2018 and have been classified at A2FL-S1* which means that it is non-combustible and that its smoke emissions are weak or absent. This therefore means Adek Comfort Grip or Adek Enhanced Grip are appropriate for use in balconies and roof terraces in buildings over 18m in height.
Why Adek aluminium decking systems are the perfect choice for high-rise balconies and roof terraces.
Aluminium is classed as an A1 fire-resistant material and will not contribute to the perpetuation of a fire. Both Adek Comfort Grip and Enhanced Grip are made of aluminium that has been coated with a decorative, polyester powder coating system called Interpon D that is manufactured by Akzo Nobel.
The combustibility classification of this coating is determined as A2FL-S1 under EN 13501-1 2018.
This determination is made from the combined results of the EN ISO 1716 Calorific value test, which measures the maximum amount of energy released by a material when complete combustion occurs, and the EN ISO 13823 single burning item test. The latter measures the heat release rate, the total heat released and the smoke production rate.
There are two elements to the classification:
Combustibility – A2FL means non-combustible (FL signifies a specific flooring test)
Smoke emission – S1 (S1 is best, S3 is worst)
Interpon D is also independently approved for use in the London Underground network.
The test regime for this approval includes smoke emission, toxic fume emissions, analysis of the material emitted, the volume of emissions, flammability, tendency to propagate fire and surface spread of flame.
