Douglas Fir Wood Tile 50x50 cm - 50 mm Thickness, Massif Central

This Massif Central Douglas fir wood tile measures 50x50x5 cm, with slats of section 9x21 mm assembled by nailing. Four tiles cover exactly 1 m², simplifying surface calculations with no wastage or complex cuts. Manufacture is entirely French. Each tile weighs 4.5 kg.

The 50 mm thickness exceeds the usual market standard (44 mm for the majority of competing products). This additional thickness improves tile rigidity under foot traffic and reduces the risk of deflection on supports that are insufficiently close together. Douglas fir is naturally durable in class 3 (no ground contact, outdoor), allowing it to be used without mandatory treatment on a terrace or balcony.

These tiles are suitable for terraces, balconies, garden paths and poolside areas. The installation is free-lay — with no permanent fixings — making them removable as needed. They are compatible with all stable surfaces: concrete slabs, adjustable PVC pedestals, concrete blocks or packers. A ventilation gap of 2 to 5 mm between adjacent tiles is recommended for rainwater drainage.

Laying advice

Lay these Douglas fir wood tiles on a flat, stable and draining surface. The most common solution is a concrete slab with adjustable PVC pedestals: the pedestals compensate for any unevenness and ensure an air gap beneath the tiles, an essential condition for ventilation and wood durability. On a well-compacted gravel or stabilised surface, the tiles can be laid directly on levelling packers.

Leave a 2 to 5 mm gap between each tile to allow rainwater drainage and seasonal expansion of the wood. Orient the slats in the same direction for a linear effect, or alternate from one tile to the next for a checkerboard effect. Cuts can be made with a circular saw or jigsaw. Protect freshly cut edges with an exterior finishing oil before laying to limit moisture uptake at the ends.

Avoid laying on waterlogged ground or in permanent contact with soil: Douglas fir is class 3 (outdoor, not in ground contact), not class 4. At garden borders, lay the tiles on a geotextile membrane to limit plant regrowth beneath the tiles.

Care and protection

Delivered untreated, Douglas fir naturally greys within 6 to 12 months of exposure. This greying is superficial and does not affect the mechanical properties of the wood. To preserve the original pinkish-brown colour, apply an exterior wood saturator at the time of installation, then renew every 1 to 2 years depending on exposure.

Clean the tiles twice a year with a soft brush and soapy water (neutral pH). In the event of moss or lichen, use an exterior wood fungicide before re-saturating. Check the condition of the pedestals or levelling packers annually and re-level if necessary.

Clear saturator: maximum protection without altering the natural wood colour
Tinted saturator (grey, teak, honey): to harmonise the tiles with existing garden furniture
Exterior hard oil: penetrating, enhances resistance to UV and staining

Frequently asked questions

What is the difference between a Douglas fir wood tile and a standard decking tile?

The 50x50 cm Douglas fir wood tile is a French-made decking tile, with nailed slats rather than clips on a plastic frame. The 50 mm thickness (vs 44 mm for the majority of products on the market) gives it better rigidity and increased durability under regular foot traffic. Naturally durable Douglas fir, class 3, does not require mandatory pressure treatment, unlike pine which must be impregnated to hold up outdoors.

How many tiles should I order to cover 12 m² of terrace?

You need exactly 48 tiles to cover 12 m² (4 tiles per m², so 12 x 4 = 48). Allow 5 to 10% extra if your surface has angles to cut or cuts around obstacles. For a rectangular terrace with no complex cuts, the calculation is straightforward: surface in m² x 4 gives the number of tiles.

Can these Douglas fir wood tiles be laid directly on an existing concrete terrace?

Yes, this is in fact the optimal configuration. Lay the tiles on adjustable PVC pedestals to create an air gap of 3 to 5 cm beneath the tiles — this allows drainage and ventilation, essential conditions for the durability of the wood. On a concrete terrace with a slope (1 to 2% for water run-off), the pedestals allow you to achieve a level surface even if the underlying slab is not perfectly flat.

Are these Douglas fir wood tiles suitable for a balcony?

Yes, provided the balcony has sufficient load-bearing capacity (to be verified with the project manager). Each tile weighs 4.5 kg. For a 6 m² balcony, you will need 24 tiles, representing a load of 108 kg to be assessed with the structure before ordering. Installation on pedestals is still recommended even at height to maintain drainage.

Why choose Massif Central Douglas fir over a composite or exotic wood tile?

Massif Central Douglas fir is a French-grown timber, with no impact on tropical forests, and a traceable local processing chain. Unlike composite decking, it can be repaired, sanded and re-treated — a damaged tile can be replaced individually. Compared to exotic hardwoods (ipe, padauk), Douglas fir offers a better price-to-durability ratio for class 3 outdoor use: exotic species are only necessary in class 4 (permanent ground or water contact).

Is the greying of Douglas fir a defect or a natural development?

Greying is a natural development of Douglas fir outdoors, expected within 6 to 12 months. It results from the action of UV light and moisture on surface lignins — mechanical properties are not affected. If the silvery grey suits your project, no treatment is necessary. To maintain the original pinkish-brown colour, an exterior saturator applied at installation and renewed every 1 to 2 years is sufficient.
