10 Tips for Installing Composite Decking |

Unlike wood whose size fluctuates with moisture changes both capped composite and capped polymer decking as well as rim joist covers will expand and contract with changes in temperature. The expansion and contraction may result in slight gaps likely noticed at the ends of boards or in splice joints. Expansion and contraction will be most significant in areas of extreme temperature change.【Get Price】

Frequently Asked Questions | NeoTimber® Composite Decking

Like all wood-plastic composite materials our decking will expand and contract in varying temperatures. The rate of expansion and contraction is dictated by the outside environment – primarily the temperature. This must be taken into account ahead of installation as this has a bearing on the “end-to-end” spacing required between boards. For more information on this aspect please.【Get Price】


In addition to offering superior low maintenance properties compared to timber composite decking has other different properties. The deck boards will expand and contract slightly along their length with changes in temperature (typically 6 mm for a 4 m board during a 40°Celsius temperature change). It is also normal that the relaxation of.【Get Price】

Do I need to space composite decking ? – Composite decking.

How Composite Decking Works | HowStuffWorks

Solid looks more like wood and is heavier than the hollow version. Because of its greater mass solid decking will expand and contract more with temperature fluctuations. Hollow composite decking has a more man-made look. However it won't expand and contract as much as solid composite decking. You need to be careful when handling it though.【Get Price】

The consequence to you as the composite deck owner is that the nice tight wood-like joints in your deck when it was installed in July may be wide unsightly gaps in February. And since plastic does not expand and contract evenly those gaps may still be there the following July. There is not a lot that can be done about it – it's the.【Get Price】

How much gap should I leave for expansion or contraction when.

As temperatures fluctuate composite deck boards will naturally experience thermal expansion and contraction. That’s why the board ends should never be installed tight against one another. There should always be a slight gap. How much of a gap?【Get Price】

The Differences Between Composite and PVC Decking - Decks Docks

When the temperature changes suddenly PVC decking can expand and contract. This makes the structure less stable over time. But because the wood fibers in composite decking make it more rigid it won’t expand and contract as easily as plastic in direct sunlight. In summary the main advantages composite has over PVC are: More authentic looking【Get Price】
