Different countries have different norms, you say. Indeed, what will not be invented in the United States, and we, as a rule, are in a hurry to learn from their experience. But not always, it is necessary emphasize, somewhere we are ahead of the whole planet.

But there are unique people (my friend, including) who are sure that the ventilation gap is not needed at all. All these are the intrigues of marketers who have come up with various systems for lathing the future facade.

Why in the USA no one makes a ventilation gap between the wall and the siding, and in Russia this is a sign of negligence and illiteracy

Before "sheathing" the facade, the question immediately "arises" of what to make the crate and what should be the ventilation gap. Hence the question, is he needed at all? If we are siding the house? For example, a house is 20 meters long and 3.5 meters high.

For one wall, you will need an aluminum profile, the price of which, in total, will be about 25'000 rubles. (fasteners are counted). We multiply by 4 walls and we get almost 100'000 rubles. These are the numbers my friend has.

He believes that if you correctly make a vapor barrier, then no ventilation. the gap is not needed at all, there will not be so much moisture there. Well, here you are, people from the USA are assembling siding directly on the OSB.

It turns out that all these bars or a profile are needed only in order to align the curved wall?

Okay, then let's turn to the manufacturer, for example, I bought TechnoNicol vinyl siding to sheathe my parents' house.

For example, I have timber siding, acacia color. New technologies, new quality siding. But what the manufacturer writes on the site, let's pay attention.

The lathing should be fixed at a distance of 30-40 mm. from the wall. Thus, condensation will accumulate on the inside of the siding, which is not afraid of moisture. If there is no gap, then all the moisture will be on the wall of your house.

Therefore, friends, always read the instructions from the manufacturer and do not pay attention to people from other countries and acquaintances.
