Decking joists are an essential part of building any quality garden deck. Lawsons’ decking joists are all made from quality timber and pressure treated to ensure a longer life. While joists are concealed, they are one of the main structural elements of your deck which is why it’s important to install them properly and be confident that you are standing on a quality product.
When installing your decking joists, make sure that they are fixed to decking posts rather than laid on the ground – this protects the timber from prolonged contact with water and therefore moisture damage and rot.
The number of decking joists you require depends on the size of your deck and your decking material. Composite decking is weaker than wood, so if you are installing your composite deck on a foundation originally used for a wooden deck, you will need to use more joists to ensure that the boards do not bend too much and break. Understanding your material and its qualities is essential to building a quality, long-lasting deck in your garden. While the boards differ, the materials for installing both timber and composite decking are much the same – the main differences are in how the decking is gapped and supported.
