Species
We propose 6 standard species, 3 of which are broad leaf trees.
Each species has its own initial characteristics and goes through a special Retification. As for wood in general, retified wood is used in different conditions and has various types of form.

Retified® Spruce
is a lower class species, mostly chosen because of its low cost and rustic appearance.
Mostly imported (Northern Europe), we also supply it, in its highest quality, from French regions high up altitude wise and where forests are dense.
The wood’s knots and breakable characteristics make it more adapted for vertical uses (cladding, outdoor and indoor carpentering, shutters…). As regards decoration, it can be used for large boards and be brushed in order to bring out its graining.. |

*Spruce tree is one of the only knotty species we deal with. The mechanical performances after treatment are largely due to the quantity and typology of the knots, which makes the Spruce tree one of the most “fragile” species after thermal treatment. Apart from that, its mechanical performances remain superior to that of a western Red Cedar tree (Resistance to flexibility: 51MPa), often used in cladding.

Retified® Maritime Pine tree
Although it belongs to the family of coniferous trees, the RETIwood Maritime Pine is an ecological alternative to exotic wood as regards cladding and terracing.
Exclusively of French origin (vastly from the Landes Region), we only deal with wood of quality in respect of severe technical specification
This strictness allows us to obtain high mechanical and durable performances which RETIwood® Maritime Pine a product of excellence ready for intensive outdoor use.
Decoratively speaking, be it interior or exterior, retified maritime Pine presents a pronounced graining which can be brought out by brushing or use of oil. Mostly chosen for outdoor uses, it guarantees stable products in all conditions (carpentering, floor boards, and furnishing) |

Retified® Scotch fir
We added to our range the scotch fir, which is complementary to our Spruce and Maritime Pine tree offer.
According to the qualities, we combine French supplying with importation. RETIwoodÒ scotch fire tree presents esthetic characteristics close to those of the Spruce tree and superior technical characteristics.
Less breakable, more resistant, its slow growth leads to fine graining. Available in longer lengths than the Maritime Pine, it is particularly adapted for outdoor carpentering and joining |

Retified® Poplar
Retification enables to make poplar tree, traditionally very rot-prone, into a species perfectly adapted to cladding. RETIwood poplar, just like other species, is primarily from France.
We only deal with wood without any knots which is selected for its ability to get retified.
Perfectly dried, poplar is then retified and allows the claddings to be adapted to the most contemporary architecture.
Its low resistance to stamping explains its vertical uses, but its exceptional stability and great durability have made it a product of excellence in this field. Because it has a homogenous grain, it can be used protected by a surface treatment or crude. |

Retified® Beech tree
Beech is a species of good chemical resistance, but impossible to use outdoors in its natural state. RETIwood Beech thanks to Retification is perfectly adapted for the most exposed conditions.
Of French origin, RETIwood beech is systematically first choice, with no knots. Thermal treatment, particularly delicate on such a dense species is applied on dried wood. Retification darkens beech, but preserves the fineness of its grain and the homogeneity of its aspect. Its mechanical resistance makes it an ideal species for outdoor terraces, public areas and outdoor furnishing. |

Retified® Ash
Retification transforms Ash, species traditionally unfit for outdoor use, into a rare material adapted to the most exposed conditions.
Particularly resistant, very hard, RETIwood Ash is the same as the best tropical wood.
Of French origin, our Ash is rigorously supplied, dried and treated.
From furnishing to outdoor terraces, not forgetting floor boards, retified ash is the demonstration of the capacity of an up to date treatment to upgrade a local species. |
