How Much Does Composite Decking Expand And Contract at Glenn Fox blog

How Much Does Composite Decking Expand And Contract. On average, over a 16’ board, composite decking will expand and contract 3/16” (around half a centimeter). The coefficient of thermal expansion (cte) is a measure of how much a material expands or contracts with temperature changes. When boards are wet and freeze, this can cause them to splinter and crack. When temperatures are high and the boards dry out they will quickly contract and can shrink and warp. The answer to that question depends on the climate in which it is installed. A materials scientist would say that composite decking has a low coefficient of thermal expansion. Wood is very much affected by moisture absorption. Although composite decking does expand and contract, it shouldn’t be much of an issue as long as the boards are installed properly with the right amount of spacing. No, unlike timber decking, composite decking does not expand when wet. How much do composite decking boards expand? How much does composite decking expand and contract? On average, over 16 feet of decking, composite decking expands and contracts by 3/16 inch (about ½ cm.) trex recommends an expansion gap of ½ inch (12 mm.) when attaching decking to walls. This applies to several brands, such as trex, which suggests an expansion gap of ½” (12mm) when abutting boards to walls at less than 40°f (4.5°c). Yes, composite decking can expand and contract in response to temperature changes like most solids, but it’s very slight.
