FAQs

Can your aluminium decking be installed on a flat roof?

Yes. Provided the underlying substructure is level and stable using our aluminium joists and suitable pedestal brackets, these decking boards can be installed upon a flat roof, and make a great solution to a long-lasting outdoor space with striking rooftop views.

How is the water drainage with your aluminium decking boards?

Cladco aluminium decking boards feature a positive drainage system that provides excellent water runoff when used on a terrace or balcony project. This is due to the slight sloping angle at which the decking should be installed upon. Please follow our easy installation guide to ensure your aluminium supporting system is correctly fitted to benefit from this.

How is the slip resistance of your aluminium decking boards?

When boards are laid perpendicular to their main walking path, due to the finely-grooved surface of the boards, aluminium decking can benefit from additional slip-resistant properties.

What colours are available in the aluminium decking range?

These aluminium decking boards, corner trims and skirting trims are available in four semi-matte colours: black, anthracite, stone grey and sand. A plain anodised aluminium finish is also available. The joists are supplied in black only, as they are hidden in the substructure.

What is the fire rating of this aluminium decking?

All Cladco aluminium decking components, including boards, joists, trims, and skirting, are A2-S1 non-combustible and fire-rated in line with regulations. This makes them suitable for installations over 18m high, such as high-rise balconies.

Why is aluminium decking suitable for balcony installations?

Due to the 2018 Building Amendment Regulations, combustible materials are prohibited for use in buildings over 18m. Cladco aluminium decking, being A2 fire-rated and non-combustible, is the ideal solution for:


  • High-rise balconies
  • Rooftop terraces
  • Raised ground-floor terraces
  • Commercial walkways
  • Hospitals
  • Refurbishment and replacement projects
Is aluminium decking water-resistant?

Yes, our aluminium decking does not absorb moisture. This makes it waterproof and resistant to rotting, insect damage, warping and swelling.

Does aluminium decking require maintenance?

This decking is incredibly low-maintenance. It does not require painting, staining, or sealing, and can be easily cleaned using mild detergent and water.

Can Cladco aluminium joists be used with other types of decking?

Yes. While designed specifically for aluminium decking, our aluminium joists can also support composite or timber decking, offering a lightweight yet high-strength alternative to traditional joists.

Can I order a sample before purchasing?

Yes. Samples are available upon request. Contact our sales team at 01837 659901 or email [email protected] to place your sample order.

I used this sealant on my metal roof flashings, and it's holding up great! Super easy to apply, and I love that it's UV resistant.
