There is a great debate about whether you should use wood or composite material such as Ecodek® or Millboard when you are choosing your decking.

In the past wooden decking has always been the preferred option but now composite materials are very popular. With better structure, safety, and durability, Ecodek® or Millboard are the options Sunrock Balconies recommend.

Whether you are choosing to install infinity glass balustrades, balcony flooring, or decking outside your home, you need to consider the differences between wood and Ecodek® or Millboard. So, before you make a choice let’s take a look!

Wood Decking


Wood decking has always been a popular choice for an outer deck or balcony, and it can last up to 40 years but, it all depends on the maintenance! A wooden decking must be cared for if you want it to last.  Here are some things you need to know:


  • Maintenance of wood decks has to be regular to avoid the build up of algae and moss which can cause it to become slippery
  • Prone to rotting, splintering, and warping so treatment is essential
  • The wood needs to be oiled or stained all over at least every couple of years
  • Application of a sealant slow down rotting


Ecodek®/Composite Decking
