The industry reaction to the changing legislation relating to requirements for the use of non-combustible pedestals has resulted in designs and specifications which are vague, to say the least.
With claims by other businesses that the headpieces and baseplates used with their ‘non-combustible’ pedestals will be made of rubber, we believe that it is important to ensure that there can be a no doubt whatsoever that our range of fire-rated, non-combustible pedestals will be Class A1 compliant.
All of our products are designed with durability and effectiveness in mind. With such serious consequences should these fire-rated pedestals fail, we strongly believe that there are no grey areas with regards to legislation and no room for interpretation.
As such, we expect to be leading the way with regards to industry innovation in the area of non-combustible pedestals.
- Our click-deck headpiece is made from stainless steel, designed to hold a ledged-profile aluminium joist (pictured)
- The headpiece is coated with RAL 7016 powder-coated paint to prevent reaction between steel and aluminium joist
- Secure fixing between pedestal head and joist means no need for additional mechanical fixings are required
- No drilling means less risk of shrapnel or sharp metal objects
- High weight tolerance and large baseplate mean pedestals can be placed at larger distances apart
- This means less units per m²
- Height can be adjusted using adjustable spanner when joist is in place
What Has Changed?
Previously, building regulations in the UK state that any material used for filler or insulation on high-rise buildings must be of ‘limited combustibility’.
However, these regulations will be amended so that only materials classed as ‘A1 or A2’ under the European Reaction to Fire classification system, will be allowed.
What do A1 and A2 ratings mean?*
The government’s official guide to rules on fire safety – Approved Document B – defines products achieving an A1 classification as non-combustible and products achieving an A2 classification as being of limited combustibility. A-class products – those classified A1 and A2 – make no significant contribution to fire growth while products with a rating of B-F are classified as combustible.
The European Classification system for combustibility classifies construction products using a series of tests. Class A materials have the best performance in a fire and are divided into two sub-classes, Class A1 and Class A2.
Class A1 – Products are described as having no contribution to fire at any stage. The BS EN 13501 test sets several thresholds for combustion performance when tested to both EN ISO 1716 and EN ISO 1182. One of these thresholds is a maximum heat of combustion of 2MJ/kg. Typical products meeting this classification include most inorganic materials such as metal, stone, and glass.
Class A2, s3, d2 – Products are described as having no significant contribution to fire at any stage. BS EN 13501 sets several thresholds for combustion when tested to EN ISO 1182, or both EN ISO 1716 and EN 13823. One of these thresholds is a maximum heat of combustion of 3MJ/kg. A typical product meeting this classification is plasterboard.
An A2 certified product has higher combustibility and can sustain flame for no more than 20 seconds. In contrast, A1 has lower combustibility and no sustained flaming when tested.
