. The "outside parquet floor" (terrace, verandah, patio, deck, porch...) consists of wooden slats fixed on their support.
. The slats are solid (harwood), stable and homogeneous.
. Using a specific mount (Woodclip) for fixing the slats to their support, the Woodclip system offers a floor without visible screw.




The backing frame

• Each installation is a particular case (framing skeleton, flag, pavement, slab, height variations....)
• The backing joists are usually fixed by means of stainless screws vith distances between each of 1.58 in to 1.97 in (according in particular to the kind of wood, the bending resistance or impact or charge resistance)




Any support must be carried out in the code of practice : slope from 0.40 to 0.75 in per yard, rigidity of the support, adapted frame...

I must fulfil the usual requirements in relation to the installation of backing frame (flatness, surface resistance, fissure's exemption, cleanliness...).


• Hardwood joist
- Lentht : 6.56 to 8 ft
- Width : 2.36 ft
- Thickness : 1.38 ft
• Or specific beams

• Without any chemical treatment, they are stable and perfectly adapted to the most severe climatic conditions.

Length : 6.56 ft
Width : 3.55 or 3.94 inches

Thickness : 0.79 or 0.87 inches
Dryness :artificial drying 12 to 16% at the delivery


Laying precautions

Plan regular plays of dilatation to prevent a possible later inflation (the Woodclip wedge : thickness 0.16 inchs inserted vertically and temporarily at the time of the laying constitutes a fast, precise and cheap solution).
Under certain conditions, it would be better to wet the Woodclip slats abundantly and regularly with a water hose. (Contact us)



Slats will be fixed on the back frame by means of special wedges in order to carry out an invisible fixing. They fit in stop, upon the Woodclip wedge


IN ORDER TO FIX THE FIRST SLAT, CUT THE TWO SMALL TONGUES OF THE MOUNT • Screw the mounts into the joists who are separated by 1.58 or 1.97 inches .
• Screwing is ensured by an A2 class stainless-screw (0.15 X 0.99 inches). (1 scrw/mount), each one aligned on the same line (use a rule or string).
• Then, insert the slat grooved into the woodclip mount tongues (with a mallet).
• When the slat is fixed, screw a new mount line, each mount fits in the previous one .
• Take good note than the alignment of the hoists must be perfectly respected .
• The assembly continues inserting a new slat and so on...
• The pointing in lenght mus be made in the back joist axi (the mount has 2 tongues for this purpose)

The joint betwen slats are more or less 0.12 inch

(naturally given by the design of the mount). To allow the dilatation of the board and the flowing, a space of 0.90 inch will be left in the end of the slat .

Plan 22 to 24 mounts per 1.1960 sq yard.

A peripheral plank can finish the assembly constituting a

frame it ensures a finishing and aesthetic touch


• Wood selected and chosen does not require any safeguarding maintenance.
• Without any treatment, wood will become grey within a few months (UV Light action, photosensitive).
• With a special treatment anti UV Light, wood will preserve its


original colour, it will be partially protected and waterproofed. However. Several months will be necessary to allow a treatment under the best conditions.
• In any case, a cleaning (twice a year – spring and autumn with diluted bleach for example) will avoid the installation of mosses and lichens, which could make the terrace slipping.




Our woods have been dried artificially, 15 to 16 % of humidity. You are advised to store them in a temperate place. Nevertheless, woods remain a “living” material, in some heat and air dryness conditions some slats might go down to a degree of humidity much lower and slightly contract themselves.

  Density at 12% : 0,67
Monnin Hardness at 12% humidity : 4,2
Coefficient of volumetric retractations : ,34%
Tangential contractions: 4,7%
Radial contractions : 2,6%
Fibre Saturation point : 24%Stability : stable


• Dark golden yellow (  turning a dark brown after sun exposures )
• Grain straight, texture coarse with an oily fee
• First class wood (long lasting in outdoor conditions), high durability, high stability.

Clear, decorative, stable wood, easy maintenance, does not heat up much into the sun, very good ageing "The best Tropical wood"

  Monnin Hardness at 12% humidity : 15
Density at 12% : 0,86 kg/m3
Resistance to Fire : M3
Resistance to the attack of insects : excellent
Resistance to mould : excellent


• Light to dark olive brown, sometimes with reddish or greenish reflections
• Fine texture, Grain straight or reverse, uniform
• First class wood (long lasting in outdoor conditions), stable, easy to dry
• Heavy and very hard wood

Movement in service is rated as very small, few deterioration in a normal use, excellent finishing


  Monnin Hardness at 12% humidity : 5
Density at 12% : 0,86 kg/m3
Resistance degree : SD3
Resistance to the attack of insects : good but still some risks…
Resistance to mould : excellent


• Olive-yellowish, becoming dark chestnut colour with the time and sun ( such as Iroko or Tatajuba wood,… )
• Fine texture, uniform
• First Class wood ( long lasting in outdoor conditions ), oily appearance, difficult to dry, weak stability

Excellent finishing, low cost
