Do you know what is the difference between frame houses from Russia and frame houses from the USA and Canada? They differ in foundation. In Russia, to reduce the cost of construction, they actively use pile foundations for light frame houses. But, unfortunately, this type of foundation is completely unsuitable for houses intended for permanent residence.
Why is that? Let's figure it out!
The main problem of the pile foundation is that you voluntarily increase the heat loss of your home.Exactly the same story awaits you if you make a strip foundation and leave a blown underground (instead of warmed floors on the ground).
When the ground is under the floor of your house, its temperature, as we know, is constant throughout the year and is approximately +7 degrees. As soon as you raise the floor in the air (on stilts or tape), the temperature below it becomes close to the street. That is, in the first case, your temperature gradient during the year does not change and is approximately 15 degrees (+22 in the room, +7 earth temperature).In the second case, during the cold winter, the temperature gradient between the indoor floor and the street will be more than 40 degrees! That is 2.5 times more. And this is the most natural heat loss.
If you take a standard one-storey house 10x10 with a ceiling height of 3 meters, then it turns out that by raising the floor above the ground we increase the area of ​​the enclosing structures, which are in contact with the cold environment by 30%. And if we want the floors in such a house to be warm, we will need to use a heater with a thickness of 300-400 mm (and if we make the floors on the ground, then the heater will need 2 times less).
You can argue and suggest to warm the base around the perimeter. Yes, it can be done this way, and the first time, most likely, nothing terrible will happen. But if you don’t leave the products, then all the lags from humidity will rather quickly rot away, and if you make mistakes during the installation of the vapor barrier, the mineral wool insulation will soak in moisture, which will cause it to stop performing its functions. And if you make the air, then the temperature of the air under the floor will practically not differ from the outdoor temperature.
For this very reason, the foundation on metal stilts and a house for permanent residence are completely incompatible things. And I don’t even touch upon such moments as shaking floors (if the performer saved on digging and strapping, which is ubiquitous) and the need to overcome several steps before entering the house from the street (the lower the entrance to the house from the ground level - the better ).
The foundation of metal piles is justified in only one case - you build a camp site and its remoteness from civilization does not allow bringing concrete or cement to make a monolithic foundation. Or if you want to build a seasonal hut for a weekend break. Also, it is impossible to do without a pile foundation in the permafrost zone, but this is another story.
If you are building a house for permanent residence, forget about the pile foundation.And about the tape with wooden floors, too, forget it. Of course, you can make a strip foundation with insulated floors on the ground, but if you can make a foundation of UWB type, there is no point in messing with the floors on the ground (this is more expensive and more difficult).
