Non-Combustible, Fully Adjustable, Class A1 Fire-Rated Pedestal

New legislation was introduced on 21^st December 2018 which specifically relates to the fire requirements of external balconies in England and Wales.

For the first time, balconies are now counted as part of the external wall and classified as a “specified attachment”. For building works which commenced after 20^th February 2019, the following now applies:

The construction of either:

new buildings which are:

• over 18m, and
• in which people sleep; or

for the refurbishment of existing buildings where:

• changing the cladding would result in lower safety (i.e. recladding over concrete), or
• the building is changing in use

then the new legislation indicates that all components of the wall must be individually tested as non-combustible (European Classification A2-s1, d0 (limited combustibility material) or A1) under the criteria of EN 13501-1

Significantly there is no longer the ability to test a complete wall (or therefore balcony) system using BS8414.

Introducing The ‘MetalPad’

We have acted proactively to the changes in fire safety regulations to ensure compliance. We have therefore developed a new range of products.

Our non-combustible, fully adjustable, Class A1 pedestal has been specially designed for high-rise balconies, terraces and flat roofs. 

Using galvanised steel to ensure strength, stability and extreme temperature tolerance, we have developed this bespoke product from scratch. It is made from 100% steel with no plastic or rubber elements and is fit for purpose.

Based upon our ASP, Universal and TD decking designs these pedestals have large, circular bases to help distribute weight effectively and designed to meet the needs of a wide variety of both commercial and residential projects. Our Class A1 product is a fully adjustable, galvanised steel pedestal specifically developed and produced to provide durability, strength & versatility where it is needed most.

Key Advantages Include:

• fully compliant to fire safety regulations and standards
• Suitable for paving slabs and timber decking
• No plastic or rubber elements
• Superior quality
• Suspended system, no need for mechanical fixings
• Fully adjustable

Offering a similar base to our universal pedestal, we will provide different headpieces for both decking and paving to ensure maximum versatility.

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 (EN 13501-1) 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 13501-1 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– 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.

The EC Decision 96 also lays out what materials are deemed to be Class A, B and so on.

Wallbarn MetalPad for paving and for decking is Class A1.
