The value of natural materials is reduced by half if they are not used in the best way.

The key to natural materials is how you use them!

Natural materials are alive.
They are alive.
So we must use them in a way that allows them to breathe.
Natural materials should not be used in an environment that kills them.

The two main points of using natural materials in the best way possible

1.Let it touch the flowing air.

2.Give it the blessings of the sun.

I am very happy to see that natural materials are being used more and more, but on the other hand, I have a simple concern.

Think of natural materials as alive, and If you use them carefully, they will serve you for a very long time.

To keep living things alive and well for a long time, it is important to create an environment where they can breathe without suffocating.

It’s grown with the blessings of the sun.
Even during use
It is important to bring the blessings of the sun to the natural materials, even indirectly.

Ideally, the flowing air should be able to touch the back and sides of the natural materials even after construction.
Sunlight and heat should also reach it indirectly.

By doing so.
This will help to regulate the moisture content of natural materials, prevent the development of decay fungi, and
It also prevents termites and insects from getting into the material, thus prolonging its life.

PAC Housing has been building houses that make use of natural materials since 1977.

Natural materials need to be used in the best way possible.

Natural materials need to be used in places where they can breathe and be exposed to flowing air.
Otherwise, decay fungi can easily grow, and mold and mites will be attracted to them.

If that happens, it’s the same old story.

The cause of the atopy and allergies was in the house itself.

As a countermeasure,

Pesticides and chemicals such as fungicides are used in building materials to combat mold and mites.
As a result
This has led to the problem of chemical sensitivity.

Nowadays, technology has been developed to eliminate the smell of pesticides and chemicals.
By doing not to smell it, the problem has become more serious because it has become latent.

In any case, in order to prevent mold and mites from forming on natural materials
As a rule, natural materials should be used in a well-ventilated place.

Unfortunately, most of them are not used in that way.

Also, maybe,

It is not uncommon for natural materials to contain chemicals such as pesticides.

The problem is getting more and more complex.
