Exterior walls construction

You can see how the exterior walls construction is going as below. This material is an avarage ceramics and is made of minerals, mixing with fibers, we call it "special cement board".

Firstly, we put a sheet around a house, the sheet has moisture transmission and water proof capability. We then mount wooden bar, maybe furring strips in English. The bar also makes airway between sheets and wall to prevent the build-up of moisture in the wall.

After above, we put hooks on the bars to receive wall materials. We sometimes Knock in a nail to fix the walls, but nail mark is noticable. Better to use hooks.

Look at the space between the houses. How narrow! You can easily see like this case in Japan. It should not be easy work for the craftsmen.

Finally, sealing compound is mounted on the joints.

This is a typical wall material here in Japan. Our house used to be made of lime plaster, wooden board and local clay mineral or mud. I think lots of Japanese people prefer these natural materials to recent ceramic walls, but it costs a lot, we can't use it. The recent wall material is good at fire resistance to fire, strength and price.
