Is it possible to fix the Océwood® composite joists on studs?

No, Océwood® composite joists are not structural profiles. If you want to use adjustable studs, you should use wooden joists for free standing structures (minimum dimensions: 45 X 95 mm).

Can I use composite joists of another brand?

We strongly advise against this: the differences in material can make the combination of Océwood® boards and composite joists of another brand incompatible. Also, the structure of your decking will not be guaranteed in this case.

Do Océwood® joists have to be screwed on to a concrete slab?

Yes, a concrete slab is essential in order to install Océwood® composite joists.

Can I use wooden joists to install my Océwood® decking?

Yes, however in this case we recommend that you use joists in rot-proof wood and with struts to prevent the wooden joists twisting, and also to follow the recommendations for installing wooden joists.

Can I use any type of clips to install my Océwood® decking?

Océwood® has developed a special system of fixings for each range of boards: 

We recommend you follow our instructions regarding fixings to ensure that they are guaranteed. For more details on the fixings relating to each range, consult the "fixings" section for each range of products.

How do I cut the Océwood® decking boards if they are too long or wide?

Is it possible to install the Océwood® boards directly on the ground (tiled, paved, concrete, etc.)?

No, a decking board must be fixed on a support perpendicular to the board, at a height which leaves an air gap and with 40 cm centres.
Joists are mandatory, to ensure there is a gap between the boards and the ground, and thus allow rainwater or washing water to run away.

Do I have to install my Océwood® decking on a concrete slab?

No, however it is essential to have stable ground upon which we can offer you wood joists (minimum dimensions 45 X 95 mm) to be installed on adjustable stubs.

Is it normal for water to lie on the board after it has rained?

Yes, Océwood® boards are not very porous. It is therefore normal for water to lie on the boards until it evaporates.

Can Océwood® boards swell if water enters and stagnates in the cells?

Only a small proportion of the formulation of the Océwood® material is wood. The board are therefore watertight. Even if water were to stagnate inside the cellular profile, the board would not swell. But, this is not possible because a wood or composite wood deck must be installed with a slope of 1 to 2% (10 to 20mm per metre) to facilitate water run-off.
