Adek Fire Resistance
Fully compliant with all fire performance requirements in Building Regulations

It is a legal requirement for any building materials incorporated into the envelope of a high rise building exceeding 11m in height to be non-combustible.

All Adek profiles have undergone independent third-party testing and have been classified as A2fl-s1 and A2-s1, d0. This means they are non-combustible,  their smoke emissions are weak or absent and they do not create flaming droplets.

Both Adek Comfort Grip and Adek Enhanced Grip are therefore classed as A2 fire-resistant decking systems and are appropriate for use in balconies and roof terraces in buildings over 11m in height.

Third party tested to BS EN 13501-1:2018

Aluminium is classed as an A1 fire rated decking material and will not contribute to the perpetuation of a fire. Both Adek Comfort Grip and Adek Enhanced Grip deck boards 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 BS EN 13501-1: 2018.

This determination is made from the combined results of these tests:

  • BS EN ISO 1716 – Heat of Combustion (Calorific Value): this determines the potential maximum total heat release of a product when completely burning, regardless of its end use.
  • BS EN ISO 9239-1 – Radiant Panel (Floorings Only): this is designed to simulate the conditions experienced by a flooring.
  • BS EN ISO 11925-2 – Single-Flame Source: this evaluates the ignitability of a product under exposure to a small flame.

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.

Adek Fire Resistance
BS EN 13823

In addition to the above, aluminium decking can also tested against the Single Burning Item (SBI) test – BS EN 13823, part of the umbrella BS EN 13501 – 1 standard.

The SBI is a test for determining the reaction to fire behaviour of building products (excluding floorings) when exposed to the thermal attack by a single burning item.

The specimen is mounted on a trolley that is positioned in a frame beneath an exhaust system. The reaction of the specimen to the burner is monitored instrumentally and visually. Heat and smoke release rates are measured instrumentally, and physical characteristics are assessed by observation.
