Composite Decking Accessories
Sylvan supplies the clips, spacers and trims that go with our boards, so you can order the whole deck in one go. Every board has a grooved channel on both edges for hidden clip fixings, which leaves the surface clean and free of screws.
Clips, spacers and trims for Sylvan decking
Six accessories cover the fixing and finishing of a standard Sylvan deck.
7mm plastic spacers
Set a consistent 7mm gap between boards for drainage and expansion, so every row lines up evenly.
Stainless steel starter clips
Fix the first board of the deck in place, ready for the hidden clip system to follow.
Locking clips
Sit in the grooved edges between boards and hold each one down to the frame, with no screws through the surface.
Bull nose edge board
A solid board with a rounded finished edge, for step nosings and the exposed front edge of a deck.
Angle flush edge trim
An L-shaped 50 x 50mm trim, 6mm deep, to cover cut board ends and the sides of the frame for a tidy perimeter.
End caps
Close off the butt edge of hollow-core boards, hiding the hollow chambers and keeping debris out.
How does a hidden clip decking system work?
A hidden clip system fixes composite decking to the frame from the side rather than through the top of the board. The clips sit in the grooves along each board edge, so once the deck is laid you see the boards and nothing else.
It is quicker than screwing every board, it avoids the dark screw heads that can spoil a lighter colour like Silver, and it keeps the spacing between boards consistent across the whole deck.
- Fix the starter clips and lay the first board
- Push the next board up to the locking clips, using the 7mm spacers to keep the gap even
- Repeat row by row across the frame
- Finish the front and steps with the bull nose edge board
- Cover cut ends and the frame sides with the angle trim
- Fit end caps to the butt ends of hollow-core boards
Always follow the fitting guidelines supplied with your order.
How many clips and trims do I need?
You do not need to work it out by hand. Draw your deck in the design tool and it works out the boards, clips and trims for the size and shape you have planned, then your quote comes back by email.
Decking accessory questions
Do composite decking boards need special clips?
Yes. Sylvan boards have a grooved channel along both edges that takes hidden clips. Stainless steel starter clips fix the first board, and locking clips hold each board down between its neighbours, so no screws show on the surface.
What size gap should be left between composite decking boards?
Sylvan supplies 7mm plastic spacers to set an even gap between boards. The gap lets water drain away and gives the boards room for the small amount of movement that comes with changes in heat and moisture.
Do I need end caps on composite decking?
End caps are made for the hollow-core board. They close off the open butt ends so the hollow chambers are hidden and debris stays out. Solid-core boards have no hollow ends to cover.
How do I finish the edge of a composite deck?
Use the bull nose edge board for a solid, rounded edge on steps and the front of the deck, or the 50 x 50mm angle flush edge trim to cover cut ends and the sides of the frame.
