Does balcony decking need a fire rating?

Yes. With the ban on the use of combustible materials on high-rise buildings set to be extended to cover all buildings with four or more storeys (or +11 metres in height) under plans the government put out to consultation in January 2020, our fireproof aluminium decking is the perfect choice for your balcony, terrace or roof garden, thanks to its market-leading A2fl-s1 rating. When considering your balcony decking material, please ensure that you choose a supplier whose baclony decking fire testing has been conducted in conjunction with the correct flooring test and installation method on a horizontal plane. Don't trust any supplier who tests to one method (i.e. on a calcium silicate backing board) and then recommends that you install to a completely different method!

What kind of structural performance is required for aluminium balcony decking?

It’s important to choose a decking material that has undergone stringent testing to guarantee its effectiveness and performance under both point load and crowd loading in accordance with relevant building codes. Look for data that meets the requirements of the most recent 2.0kN point load @ 0.5% deflection (L/200) BS 6399-1:1996) standard.

Does aluminium decking get hot?

No. Due to its unique composition, our aluminium decking boards stay cool even in hot weather, making them a great solution throughout the year. This also means that the boards are barefoot friendly, and safe for children and animals.

Is aluminium decking suitable for outdoor flooring and balconies?

Yes. While aluminium decking is primarily used for terraces and balconies, it also makes a safe, cost-effective option for public spaces and general flooring use. it is 100% recyclable at the end of its life, making it a sustainable and eco-friendly decking option.

Aluminium decking doesn’t stain, fade or rot, so will only require minimal cleaning throughout its life cycle. All you’ll need to do in order to keep your balcony decking looking great is give it an occasional wipe or scrub.

How to replace balcony decking?

Our aluminium decking comes with a 25-year warranty and a long service life, so you’ll likely never have to replace it. It's also 100% recyclable.

What is the life expectancy of aluminium decking?

Our aluminium decking has an expected service life of over 25 years – but under normal residential conditions it will likely last much longer. The best part is that our metal decking boards are recyclable, so they can still be put to good use even if you decide you want something different and choose to replace them.

How many components make up Dura aluminium decking?

Our decking comes with three separate components for easy installation. The innovative tongue-and-groove design means that they slot together with ease, reducing install time and saving costs. Furthermore, our boards are ready to install as soon as they arrive on site.
