Non-combustible walls

It is consultation contents to have you call almost every day.
We want to stick wood to the wall where interior restrictions are imposed by the Building Standards Law, but we can not construct it unless it is semi-flammable or more.

Unfortunately this does not become non-combustible.
The Ministry of Land, Infrastructure, Transport and Tourism’s quasi-non-combustibility certification does not assume on-site construction, but targets industrial products produced in factories.
Therefore, even if a nonflammable liquid is applied on site after construction, it will not be recognized as a certified product.
Not in soufa, but in general materials.

It is easy to get confused with products that have obtained certification numbers as noncombustible paints.
Assuming that the base material is a non-combustible material, those products have obtained certification numbers in the sense that they do not promote combustion even if applied on them, and have performance that makes it difficult to burn itself .
Therefore, it is not a product that makes the base material nonflammable.

This area is not widely recognized, and it seems that there are cases where government offices and fire departments are thought to be able to respond by applying it on site, and our company often receives inquiries. However, it does not become non-flammable by on-site application.

So how to solve it? This means that this should be adopted as “quasi-noncombustible certified material”.
It is sold as an industrial product that has passed the certification test and obtained a certification number by a non-combustible wood manufacturer. By purchasing this and installing it on the wall, it will correspond to the quasi-noncombustible certification.

If the products you want are not available from the non-combustible wood company, you may have to give up under current legislation.
It will take several years to re-acquire the certification number for unspecified tree species and thinness.

If you really want a woody look, you may want to use non-combustible veneer plywood.
We also manufacture and provide some.

Although not widely recognized, these non-combustible woods are soaked with large amounts of non-combustible agents.
Conversely, it can be said that incombustibility cannot be achieved unless a large amount of incombustible agent is impregnated.

Therefore, it is not possible to impregnate a large amount of incombustibles with on-site painting (* Only a small amount can be entered by brushing), which is far below the incombustibility certification standard.
This applies to both non-combustible and non-combustible. Flame retardancy is the lowest standard, but even with this standard it is difficult to clear by painting.

I’d just like to officially announce it from the Ministry of Land, Infrastructure, Transport and Tourism, but is it difficult?
It seems that the design offices are also having trouble with non-combustibility certification because they do not have a base, so I hope that they will create guidelines in consideration of the increase in wooden design designs for the Olympics.
