Hello! This is Office restoration Dot Com website blog.

Our company is an interior finishing construction company professionally mainly at Ikebukuro area, Tokyo, the midpoint, also in all over Kanto area,

in charge of all of interior finishing construction work, such as LGS(=light gauge steel) work, board work, cloth・floor finishing work, and so on.

 

This time, we are explaining,

incombustible materials.

 

What are incombustible materials?

 

Briefly speaking, incombustible materials are designated as 「not combustible materials」.

If a normal fire occurs, it is defined to be fulfilling the following criteria.

・It should not be a burning material.

・In fire prevention, it should not come about poisonous deforming, melting, cracking or other damages.

・In evacuating, it should not generate poisonous smoke or gas,

In addition, there are three criteria of the property of which can be shown concerning the limit.

1.Incombustible materials.

2.Quasi-incombustible materials.

3.Flame-resisiting materials.

It is separated as above three kinds.

Incombustible materials for 20 minutes, quasi-incombustible materials for 10 minutes, and flame-resisiting materials for 5 minutes are decided.

 

What kind of materials there exist?

 

In the first place, there are two kinds of authorization methods for incombustible materials.

・Decided by Minister of Land, Infrastructure, Transport and Tourism.

・Obtained the authorization by Minister of Land, Infrastructure, Transport and Tourism.

 

Among them, the decided are included:

Gypsum board, glass wool and so on, which is included frequently used for interior finishing work materials for building use materials.

 

Why it has been decided?

 

Somehow, although we may think that your own house・shop or store shall not be burnt.

If we explain briefly, there are the following reasons:

・In order to decide on ceiling and wall material used at the kitchen and the place where heat of fire is used.

・In order to decide on ceiling and wall material used at a kitchen or the room where there is heat of fire.

・In order to decide on ceiling and wall material at a room without window or an opening.

・In order to make the standard of building materials at the appointed area for fire prevention・quasi-fire prevention, based on the city planning law.

 

Although we omit the explanation about the fire prevention・quasi-fire prevention area this time,

the city planning law is the regulation for city development・safety,

which is different from Building standards law. However, together with this Building standard Law, it will be one of the items to be noted.

 

This time, although we omitted the details not related to interior finishing work,

as the Japanese site(if you click the underlined Japanese site) here ls described plainly and written in details.

So, if you are in mind, please be sure to visit this site by all means.

Summary

 

If you request interior finishing work, although it seems that you may not necessarily understand all of these, however,

still if you request newly reform or renovation work,

it seems that you do not lose anything if you remember our above explanations at the back of your mind.

 

It seems that you should be especially careful of similar case such as「We would like to refurnish into a room using for heat of fire,

instead of previously originally used for 〇〇」。

For that reason, when you request the construction work company, you should tell the purpose.

Furthermore, you may request the construction company to explain to you if it is necessary to change its construction materials.

It seems that it may be probably nice to understand the above points in advance.

If you have any unclear point, please be sure to ask for counselling with our company.
