Tough Decking WPC Composite Decking Joists are available in 2200mm(L) x 54mm(W) x 30mm(H). Designed to be laid directly over a suitable solid substrate. The composite decking joist should be evenly spaced out at no more than 367mm centres. Like many other outdoor walking surfaces, composite decking can get hot due to sun exposure and hot weather. That’s why it’s important to consider your climate, sun exposure, and deck color when choosing your boards.TimberTech deck boards are far superior to traditional wood in several ways, including in their ability to handle direct sunlight with less heat retention and minimal color fading. Find out why TimberTech decking is the best composite decking for full sun decks.The four disadvantages of composite decking are that it fades with sunlight, warps in hot weather, wears down in high-traffic areas, and, worst of all, causes timber subframes to rot and become unsafe. Interestingly, all these issues can be solved by choosing an aluminium decking board that has an integral gutter.Solid composite decking joists are perfect to use as a subframe with composite decking, creating a fully low maintenance decking system.
Should a deck joist be 2×8 or 2×10?
The largest deck you could build with a triple 2×10 flush beam, 3 posts, and 2×10 joists spaced 16 O. C. When installing composite decking, joists should generally be spaced no more than 16 inches OC for standard applications. If you plan to install your decking diagonally relative to the joists, 12-inch spacing is required.Joist Spanning and Gapping Joists must be spaced on center at either 12”, 16” or 24” depending upon the size of the deck board and whether it will be used for residential or commercial use. Trex in residential or commercial applications at 100psf or less and some wood decking.Deck joist spacing should never exceed 16″ on center (with the exception of MAX deck boards, which allow for maximum 24″ on center). For a more rigid feel, 12″ or less may be preferred. If adding additional framing, be sure to keep all boards level and in plane across the tops.Tough Decking WPC Composite Decking Joists are available in 2200mm(L) x 54mm(W) x 30mm(H).

The gap between each individual deck board allows for rainwater runoff, plus the natural expansion and contraction of the wood throughout its life. You need an expansion gap of 5-8mm between the boards.What’s the correct gapping for composite decking boards? You should always leave a space of between 3mm and 6mm between composite decking boards. This is to allow for the boards to contract during lower temperatures and expand during higher temperatures without the boards being damaged.
