6. Everything you need to consider about joists

The Joists or sub-frame are timber pieces that will provide support for your composite decking. The ideal spacing between joists is 30 centimetres and about 25 centimetres for commercial composite decking installations. Make sure before you use the joists in any composite decking installation that they are structurally sound and have been treated to preserve the quality of the timber. Treated timber joists also prevents rot leading to a longer service and protects against insect or fungal attack. The joists should also be wide enough (minimum 2 inches) to ensure your composite decking is supported.

7. Consider the Hidden Fastener Method

To fasten your composite decking you will need some special screws, screwdriver bit and composite decking plugs with the same design as your decking. It can give you a uniformed surface plus it will save a lot of time than adding some plugs on the heads of each screw. What you just need to do is to countersink the screws using the screwdriver bit. Hammer the plug of the same kind as your decking. It will be more polished and looks as if the fasteners are invisible.

8. Use colour matching fascia, L corner trims or end caps

You can use colour matching fascia, L corner trims or end caps to provide you with an easy and quick way to attach at the end of each cut on your composite decking panel. These provide a clean neat finish to the look and appearance of your new composite decking project. A job well done and in a more efficient manner.

This is one of the advantages of having a composite wood deck. Measuring and cutting can cost so much of your time during the installation process which you definitely do not want.

10. Choose the off-season installation
