A high quality product that's chemically treated but still retains its' natural features. 

Basic summary of general non combustible wood in Japan.

Non-combustible wood is a construction material which is manufactured by soaking or vacuum pressuring a boric acid or a phosphoric acid into natural Japanese Cedar, Hinoki Cypress and so on. This allows for the lumber to stay close to its natural state while acquiring fire retardant properties. The Japanese Building Standards Act was revised for this type of fire resistant lumber to be used in several types of buildings including; homes, apartments, condominiums, department stores and underground structures. The product has to be authorized by the Japanese minister of Land, infrastructure and transport to meet its expectations and highest standards. The product has passed "cone calorie meter" test from a designated laboratory by the Japanese minister of Land, infrastructure and transport. The requirements of this test are listed below.

1. Whole calorie count must be below 8MJ/M2.

2. There must be no damage to the materials after heating including cracks, warping and deformities.

3. It must not be exceed 200KW/M2 in the maximum heat.

4. It must not emit toxic gasses.

If the requirements above have been met, its rank is classified as follows;

- Non Combustible Material = 20 minutes

- Quasi Noncombustible Material = 10 minutes

- Fire Retardant Material = 5 minutes

Since Japan is prone to natural disasters, strict guide lines are put in place. We have passed this strict product testing.

Caution

1. Since wood is natural material, the color, texture and wood patterns on each plank are different.

2. Since natural wood is used as raw material, this product may have slight bends, twists and shrinkage after processing.

3. Urethane paints are recommended when using this product indoors.

4. It is recommended that this product is stored in a dry and dark room.

5. This product is twice the density of normal cedar. This means it is twice as heavy and hard. Precautions should be taken when working with this product.

6.If the plank forms white deposit on the surface, simply wipe it with a cloth. This does not affect its' properties.

Non-combustible material certification issued by the minister of land, Infrastructure, transport and tourism in Japan.

1. First, lumber from green cedar is air dried.
2. Then it is dried in a kiln drying space until its moisture content drops to 15%.
3. The lumber is carved with a Tongue-and-groove appearence.
4. All lumber is weighed before the chemical injection.
5. The cedar is then put into a vacuumed sealed tank. Chemicals will be injected to the lumber using pressure for better absorption.
6. All injected lumber is weighed to insure that the chemicals have been injected properly.
7. Injected lumber is air dried.
8. Then once again dried by a kiln until there is no decrease in weight.
9. The final product is complete.
