No more exotic woods that are often expensive and uneconomical ... Today, manufacturers offer much more interesting alternatives, both elegant and practical ...
Exotic, chic but ...
In Deauville, the famous boards are in azobés, a beautiful wood of the equatorial forests, extremely dense and rot-proof, resistant to insects and fungi, and very little sensitive to hygrometric variations. In short, the ideal for the outdoors. A number of other exotic species also work: Ipe, cumaru, massaranduba, tatajuba and, of course, teak. All have unparalleled durability. With a beautiful mahogany more or less tinged with red, they turn gray with time and talk with oil. Problem: quite expensive, they come from far away (which is not very ecological) and their slaughter contributes to deforestation. Always check that they come from eco-managed forests.
Wood from here, autoclave
Putrescible, the woods of our countries are rarely recommended for terraces. Except to subject them, after drying, autoclave treatment during which we inject preservatives to the heart of the wood. It is sold with a warranty that can be up to 20 years. Pine and Douglas fir are very often proposed as well; they have the same qualities as exotic woods, transport and the risk of deforestation less. A more costly but totally eco-friendly alternative is the re-wooded wood, which is a wood heated to a very high temperature that gives the local species the same qualities as an exotic wood. Finally, the robinia, pseudo-acacia, very dense is perfectly usable outside (Alternabois).
Composite wood, practical
It is not quite wood, even if it looks, but it is not plastic! Composite wood is usually composed of half wood fibers, finely ground and dried sawmill waste and recycled polyethylene (thermoplastic polymer made from milk bottles, shampoo bottles, laundry cans, and other recyclable plastics). . Its advantage? It is recyclable, contains no glue or solvent, is non-slip, its color is stable over time and it makes it possible to value sawdust and wood chips from sawmills. He is not afraid of cleaning with water under high pressure. Finally - a detail that is important - it avoids any risk of splinters.
Standing wood, an old-time look
These oak pavers were cut in the wood perpendicular to the trunk fibers, micronized (a treatment that optimizes insecticides and fungicides), then impregnated with linseed oil for better durability. Its more? An aspect "old-fashioned natural". The pavers "Querex" land on a bed of sand after stabilization.
