Wood and flames

In terms of ecological choice, Yakisugi is hard to beat. After all, it's simply wood, burned on the surface and treated with 100% natural oil. 


Thus, we are in the presence of a biodegradable, renewable material whose manufacturing process does not require the use of any chemical or toxic agent.

Local non-threatened

raw material

At Arbres et Bois, we prefer to use local wood to the wood of the United States or western Canada. We also make sure never to use wood from endangered forests. It is through our network of suppliers that we managed to find materials from forests located within a radius of less than 400 km from the Montreal, Quebec, and Ottawa regions.  

 

This makes a final product that is an excellent alternative for LEED projects (Yakisugi = local, biodegradable, without any chemical agent, and sustainable product).

WE TRAVEL LIGHT

In order to reduce our greenhouse gas emissions, we favor the use of vehicles adapted to our deliveries and the most energy-efficient solutions possible.

NO MORe dyes,

paints and varnishes

Unlike natural wood, which requires annual (Ipe, teak, mahogany) or biennial maintenance (cedar, pine, larch, hemlock),  Yakisugi can be left without care, as seen in Japan, or can be maintained with a simple coat of natural oil every eight to ten years, 
which is the Scandinavian method. This simple, quick and efficient care can be provided for you by our team of outdoor wood structures maintenance. 

 

resistant + durable

A High degree of ROT RESISTANCE

Bracelet POST-APO

The degree of rot resistance refers to the time that materials take before starting to rot. Several factors can influence this degree: the presence of water or humidity, aeration, climate, sunshine, etc.

 

When it comes to outdoor projects and following Japanese tradition (Yaki = burnt, sugi = cedar), cedar is used as material, a wood known to be very resistant to rotting because of the tannins (natural substances playing a defensive role against parasites) that it contains. The burning process also maximizes its properties.

Fight fire with fire

Paradoxically, burning wood planks on the surface will give them greater fire resistance than boards left unburned. 
Indeed, when analyzing building materials, two main criteria are taken into account concerning the risk of fire: the propagation speeds of flame and smoke.

In both cases, Yakisugi offers very good performances. See the table below for technical data.

Resistant to ultraviolet rays

Bracelet POST-APO

Once treated using the Shou-sugi-ban method, the wood will withstand the effects of ultraviolet rays, which are so damaging to natural wood. 


Unlike cedar or natural pine, which will tend to turn gray in the first year, Yakisugi will not. In some cases, bluish reflections may appear after several years. 

 

It is recommended to apply a coat of natural oil every 8 to 10 years if one wants to preserve the black aspect of the wood. Obviously, when used indoors, Yakisugi does not require any treatment. 

what is the astm e-84?

ASTM-E84 is the test used in the United States to measure the flammability of wooden constructions. 
When it comes to how quickly flames could spread and when materials
are used inside a building, the results obtained are divided into three classes: Class A (0-25), Class B (26-75) and Class C (76-200). 


Regulation generally requires a class B in North America. Concerning the diffusion of the smoke test (SDI Smoke developed index), 
one must usually be below an index set at 450.

HIGH RANGE + PROFITABLE

Let's be honest, although it is far from being the most expensive choice of material, Yakisugi is also not the cheapest, simply because it is a finished product and not a building material for which one must then invest time and money to dye it or paint it.
 

The wood used as a base material, cedar, is also more expensive than other woods like pine, hemlock or spruce, but much more durable. The medium and long term economy is easily calculated: little to no maintenance, which means little to no cost related to the purchase and the application of dyes or paints, and an exterior coating that will last twice as long as a standard wood coating.
 

Here are, for illustrative purposes, some comparisons for a surface of 1000 square ft used as outer cladding (tongue-and-groove wood). This is an average of the prices found at the main retailers in Quebec.

As we can see

the cost of maintaining exterior cladding is an important aspect that must be taken into account at the time of purchase. Furthermore, choosing not to maintain outdoor cladding is the wrong choice because it will make the wood dull and greyish, and will considerably diminish its lifespan.

 

In this sense, yakisugi represents a very interesting alternative, 

ecologically, aesthetically and economically!
