Hidden Fastener System
The benefits of using a hidden fastener system to install composite decking
At EnviroBuild, we believe the best way to install a deck is using hidden fasteners.
The reason we designed our deck to suit hidden fasteners is because it enables a soft installation. This means the deck boards are not drilled into directly. Avoiding damage to the boards ensuring longevity and an aesthetically pleasing finish.
Hidden fasteners are commonly known as secret fixings as they are screwed into the joist framework, thus hiding them from sight.
A groove runs along each side of the board which allows the boards to essentially slide across the joists and are held in place by the fasteners.
Nearly all builds require starter fasteners – this fastener is a metal clip, used to secure in the first and last board of each run. Essentially it supplies the stability to the outer decking thus ensuring the longevity of the decking body.
We recommend one box of 100 for every 25 square metres, but this can vary with the design of the deck.
The hidden fasteners are the fasteners that create the gap between boards and are secured at each crossover of board and joist. They will hold the boards in place across the main body of the decking.
3mm hidden fasteners
3mm fasteners are made from stainless steel and are secure clips that are screwed directly into the joist – creating a 3mm gap between boards. The narrower gap is ideal if the deck is a lighter colour.
For example we would recommend 3mm clips for our Silver Birch decking, as the decking looks best when the gap visibility is reduced.
If you find yourself preferring the 3mm fasteners – they are easily installed and look great with the all Hyperion composite decking.
6mm hidden fasteners
Our standard 6mm fasteners are made from 100% recycled nylon and, as the name suggests, create a 6mm gap between the boards.
The benefit of a 6mm gap between boards is the accessibility it provides. If required a screwdriver can fit between boards and undo the fasteners, thus releasing a singular board.
This is great if you want to take up a singular board as the reprisal makes minimal impact on the rest of the deck area. This is also great if you are a self / first time installer as it gives you a bit more breathing room when installing the deck.
We can also provide decking gap inserts for our 6mm clips to prevent items falling between the boards.
