2.    Aluminium decking is far longer-lasting compared to composite decking 
3.    Aluminium decking can resist twisting and warping, whereas other decking doesn't 
4.    Aluminium decking is considerably lighter than composite decking 
5.    Aluminium decking is non-combustible while composite decking is will burn 

Q5. Can Aluminium Decking be used for balconies?

Yes, aluminium decking is a good choice for balconies. However, when specifying the product, it is crucial to ensure that it is rated to A1 or A2-s1,d0 to comply with legislation and provide an appropriate level of safety. Ask to see the company's EN13501 Classification Report for the product. 

Q6. Is Aluminium Decking non-combustible?

Yes, aluminium decking is non-combustible. However, it is advisable to check its fire rating. In certain types of buildings, only non-combustible decking can be specified.


Q7. What is the difference between 'Fire Resistant' and 'Non-Combustible'? 

Fire Resistant means that the product will help to slow down the spread of fire, for example, timber that has been treated with a fire retarant chemical might be more difficult to set alight.
Non-Combustible, on the other hand, means that the product will not burn at all and will never provide any contribution to a building fire. To be sure, always check products are A1 or A2 rated to EN13501 standard.
