Frequently Asked Questions 

Hopefully you will find answers to some of our most frequently asked questions. Please dont hesitate to get in touch if you need any extra information. 
Which way can I lay the decking boards? 

The boards can be laid with either side facing up, the small grooves provide the best slip resistance. 

Do I need to use the invisible clips & screws? 

YES! The clips are very important, as they allow the deck boards to contract & expand in a longitudinal direction. It is important that one clip is used at the end of every board. 

If the clips are not used and you use screws to fix the boards directly to the wooden joist below the deck board will buckle and eventually break. Failure to follow the correct installation instructions will affect your product guarantee 

 

The beauty of the clips is that there are no surface fixings, this is great for small hands & feet and ideal around pools & hot tubs.

Can I use wooden joists or subframe? 

Yes! Most of our customers use a wooden frame, this will not affect the performance of the composite boards. Composite joists are available 200mm x 50mm x 30mm 

All joists must be layed perpendicular to the decking boards. All joists must be placed at 350mm centres to ensure the boards are adequately supported. 

It is necessary to double the joists (or use a double thickness joist ) at each butt joint of the boards.

Are the decking boards structural? 

No. Each hollow board can support up to 250 KG per square metre. Hollow (honeycomb) boards are ideally suited for residential applications, homes, gardens, poolside’s, anywhere with light traffic. 

Solid decking boards are available for commercial applications: Hotels, Garden Centres, Cafes, Councils & Country parks.  

 

This means you cannot run any machinery over the boards, including cars & ride on lawn mowers. 

Do i need to leave gaps in between the boards? 

 

Yes. Gaps are crucial to ensure to longevity of your deck and maintain your guarantee. The boards are a combination of wood & plastic, and the plastic needs to contract & expand in the heat, and cold. The small gaps simply allow the space for the boards to move.
