Does Composite Decking Expand and Contract?

Composite decking is made of plastic and wood fibres, so it expands and contracts very with changes in temperature and weather. This is something you’ll need to take into account when installing your deck, as you’ll need to leave a bit of space between the boards to allow for expansion.

Take a look at the Ecoscape composite decking installation guide for expert advice on how to install decking and leave room for expansion.
