Why porcelain works best for roof terraces

Why porcelain works best for roof terraces


  • Reduced weight load.
  • Natural strength.
  • Low water absorption rate.
  • Extensive choice of colours and patterns.
  • Ease of installation.

Need we go on?!

If you’re looking for a high-performing, slip-resistant option for a roof terrace project, porcelain firmly ticks every box.

A light, strong, simple solution

If you regularly specify tiles for roof terraces, you’ll be familiar with the weight challenge, especially if your slabs need to be laid on a pedestal support system. In fact, it’s all too easy to fall into the trap of specifying products that are too heavy or not strong enough, with concrete, sandstone and granite being regular culprits.

You need a strong tile – yet, especially with natural stone and concrete, a slab thickness of at least 60mm is required.

  • That’s why architects are turning in increasing numbers to porcelain, where our 20mm tiles provide more strength – 55N/mm2 to be precise – than a 60mm natural stone option.
  • As a result, not only is the weight load on the roof reduced – installation is easier and safer.

Slip resistance guaranteed

In any roof terrace project, you need to have an eye on the slip factor.

The slip resistance rating of your tile material should be 36PSV or above. And an engineer should be involved to determine the strength of the slab that’s required, depending on the laying method.

  • Concrete, sandstone and granite are not only heavier and weaker – they’re also more likely to grow moss and algae, meaning that the roof terrace surface could become slippery.
  • Porcelain tiles has a very low water absorption rate – 0.04% – meaning that moss and algae growth is less likely.

Plus, to top it all off, porcelain is chemical and frost resistant – a winning option all round when it comes to safety.

And don’t forget the aesthetics

Finally, porcelain is an incredibly versatile option.

  • It’s a beautiful material, and you can choose from a huge variety of colours and patterns to suit your project.
  • What’s more, porcelain is stain resistant, meaning it’ll maintain its beautiful complexion, whatever the weather throws in its general direction.
