Fire Resistant Balcony Decking

Fire Resistant Balcony Decking

In the recent years, there has been a lot of awareness focussed on the need for improved fire safety products used on buildings, including balconies. So much so that new regulations have been brought in that ban the use of combustible materials in external wall systems and balconies.

Our aluminium balcony decking system is manufactured from aluminium which makes it naturally fire resistant and non-combustible. When you compare previous popular decking materials such as timber, wood-polymer composite and GRP which are all flammable (timber particularly so) aluminium is the obvious choice. Our decking boards are class 1 or A2-s1, d0 fire rating (depending if you require the coating) and are non-combustible.

Our Ali-Deck balcony decking boards have been designed specifically for installation on balconies at a height. There’s two boards within the range which measure 20mm wide and a choice of 20mm and 30mm deep, this fire-resistant balcony decking is light in weight, yet high in load-bearing capacity meaning it requires less supporting steelwork than heavier materials, thereby significantly reducing costs.

You will also save costs as the installation time is up to 50% quicker than other products on the market due to the quick-fit clip-in feature.

  • Balcony Decking – Designed to be installed at a height such as on balconies
  • Fire Resistant Balcony Decking – Our balcony decking boards are Class A1 or A2-s1, d0 fire rated (depending on the finish chosen) and therefore conform to the new UK fire regulations
  • Full Drainage – The aluminium decking has cavities to allow the water to drain through, away from the decking, avoiding water laying on the surface
  • A Complete Aluminium Design – The complete system is made from aluminium for strength, longevity and minimal maintenance
  • Quick to Install – The decking boards are quick-fit clip-in systems that are 50% quicker to install compared to all other decking systems on the market
  • Easy Fix to Existing Steelwork – Fixing to existing steelwork is easy without unnecessary penetration
  • Made from Recycled Aluminium – 30% of the aluminium used to manufacture our aluminium balcony decking has been recycled and can be recycled multiple again times over
  • 25 Year Life Expectancy – Aluminium naturally lasts much longer than timber or composite and to show our confidence, our balcony decking is supplied with up to a 25 year life expectancy
  • 100% Recyclable – Although the decking is made from 30% recycled aluminium, it can also be recycled time and time again and therefore will never need to end up in landfill if disposed off correctly
  • Can Cover Any Size Balcony – The Senior board is 120mm x 30mm deep and the Junior board is 120mm x 20mm deep, however they can be cut to size along the width and fitted together to cover balconies of any size
  • Minimal Maintenance Required – Aluminium decking does not require treatments, to keep it clean and maintained, it is advised that you wash it as and when needed with warm soapy water and a lint free mop/cloth
  • Available in Two Colours – The aluminium decking is covered with QUALICOAT which is a powder coating finish that is available in two colours; Textured Grey and Textured Sand
  • Will Not Warp Over Time – Unlike timber, aluminium does not expand or contract in the heat and wet weather and will not warp, make it last much longer than timber decking, without the need for regular treatments
  • Get Ahead on the Installation - You can install 90% of the deck board prior to the installation of the balcony if required, once the balcony is installed you can then install the remaining boards
  • No Need to Drill Holes - Ali-Deck enables you to install it onto existing sub frame sections without having to drill additional holes if required
  • 10 Year Warranty - Supplied with a 10 year warranty

Specification

Can be cut to size
The decking board has been designed to have 3 main supports underneath, so you can cut the board on both sides if you only have a small gap to deal with. The decking board will still be structural due to the upright support under the correct point that it features. To ensure high strength in all situations, we also looked at the point loadings for when cutting the board with a ‘cantilevered’ section and increased the radius on the underside of the board to strengthen the board in the areas required to cope with a good point load.

Fire resistance
The balcony decking boards are constructed from structural grade T6 aluminium. As with all metals, when faced with extreme heat the strength of aluminium alloy is reduced at a rate dependent on the material. The T6 grade structural aluminium has a useful maximum working temperature limit that ranges from 200° to 250°C. Above this temperature the strength is significantly reduced. See more information regarding the fire resistance further below.

Save time by installing 90% of the boards prior to the installation
The board has been designed so that it can be installed from the top with a slotted machined centre section. This enables you to pick up on at least one of the bolt channels in the 3-way bolt channel to reduce the need for drilling whilst on site. You can then lay decking boards into place once the balcony is installed by using the bolt channels and the threads facing up and simply apply the nuts and tighten up (this should be reasonably quick to do).

Can be installed onto an existing sub-frame section without drilling additional holes
The aluminium balcony decking features a 3-way extrusion, two up and one down. This gives you the option to make sure a bolt can pass through the box section on the existing balcony at any point along the box section and then be secured. You can then decide on the channels to slide the bolts into place depending on the position of the decking in relation to the position of the box section. You need only choose one bolt channel but choosing two gives you the choice to complete the installation without drilling the decking.

Sufficient drainage between the boards
You can choose the space you want between each board during the installation of between 4mm and 10mm however, we would recommend 6mm as standard. This is because the boards will drain much better if a minimum gap of 6mm is created.

The board has a cover strip on the top of the board which has a positive click leg on both sides, it’s a long leg so any point load and downward loading is not a problem. This is a quick fit option that removes most of the problems associated with other composite decking products.

Fire Testing

We understand that the fire rating is extremely important to all our clients, and can confirm the following:

Aluminium in Building:
Aluminium alloy components used in building complies as follows. As defined by BS 476: Part 4 and the 1974 SOLAS Convention (as amended) aluminium alloys are ‘non-combustible’ and provide Class 1 surface spread of flame to BS 476: Part 7. In addition, BS 476: Part 3 covers external fire exposure roof tests and the classifications laid down in the standard range from AA to DD. The first letter refers to the fire penetration performance and the second letter to the surface spread of flame. Aluminium and its alloys are rated AA, the highest possible under this classification system. Materials are also tested for fire propagation performance to BS 476: Part 6 (1989) and coating systems are considered. Aluminium achieves excellent ratings under this Standard.

Qualicoat Powder Coat Process 1. BS476
British Standard 476 refers to fire tests on building materials and structures. The parts of this standard that are of most relevance to powder coatings are Parts 6 and 7.

Part 6 - Fire Propagation
The result of this test is a fire propagation index. It is a measure of the contribution to fire growth made by an essentially flat surface. The results of the test are specific to the test specimen i.e. the product on that substrate in the form in which it was tested. Therefore, it cannot be used as a method for assessing the product in all situations.

Part 7 - Surface Spread of Flame
This is a method of measuring flame spread along the surface of a specimen. Again, the results of the test are specific to the test specimen i.e. the product on that particular substrate in the form in which it was tested. Therefore, it cannot be used as a method for assessing the product in all situations.

As defined in the UK Building Regulations 2000 - Fire Safety Approved Document B, the highest product performance classification for wall or ceiling linings is Class 0. This is achieved if a material; (a) Achieves a class 1 rating in BS476 Part 7, and (b) Achieves a fire propagation index of not more than 12 and subindex of not more than 6 in BS476 Part 6.

Test Results
Our special coatings have been tested to BS476 Parts 6 and 7 and have met the criteria for Class 0 building regulation approval.

Quaicoat Powder Coat Process 1. BS476 - London Underground Approval
Approval for use in London Underground is a good indicator of fire safety. The product must be tested for:

  • Smoke Emission
  • Toxic Fume Emission
  • Qualitative analysis (what is emitted)
  • Quantitative analysis (how much is emitted)
  • Flammability
  • Fire propagation
  • Surface spread of flame

Ali-Deck Slip Resistant Inserts are made from PVC Polymers, they are generally referred to as “Self-Extinguishing” which means that they will burn whilst a high enough heat source of flame is applied to them but once removed they stop burning.

Colour Options

The balcony decking is covered with a 5-stage powder coating process called QUALICOAT which is available in two colours; Textured Sand and Textured Silver Grey as shown below.
