Winter is close, and if you still haven't gotten around to insulating cold floors, it's time to hurry up. For wooden floors in the house, it is very important to choose the right insulation, taking into account the characteristics of the coating. What's good for concrete can be damaging to wood, so be careful. For example, polystyrene, which is now popular for wooden floors, is not suitable for many reasons: it emits toxic substances and is fire hazardous. What then is better to use? Let's figure it out now.

Thermal insulation of wooden floors with mineral wool
Very easy to use and waste-free insulation material. It is used down to the smallest scraps, so that in this regard, you can save on it.
But not everything is so simple: if the mats are not properly laid, they will accumulate moisture, and this will lead to rotting of the tree. So laying mineral wool insulation without good waterproofing will not only not help, but will also damage your floors.
Sawdust as insulation
It's cheap and very practical. Sawdust can be used in natural form or as wood concrete or sawdust concrete. Mixing sawdust with building mixtures makes the insulation durable. Sawdust does not settle and does not rot if properly processed. But they, like mineral wool, need waterproofing.
Warm floors on expanded clay
At the basis of expanded clay, a natural material is clay, so that with environmental friendliness everything is also in order. Plus excellent fire resistance and lack of compaction and caking tendencies.
The only drawback of expanded clay is that it takes a lot. You will have to pour a layer 5 times larger than the same mineral wool. If we were talking about insulating the ceiling, then this, of course, is not very good - the floors will have to hold such a weight. And with floors in a private house it is quite acceptable, so you can safely fall asleep.
What other insulation materials are suitable for wooden floors
If we consider cheap and natural materials that are safe for health, then you should pay attention to some more types.
How to choose a floor insulation in a private house
As you can see, each material has its own nuances, and they all mainly rest on the need for high-quality waterproofing. This is understandable: wood does not tolerate dampness, so if you want wood floors to last longer, be sure to provide them with moisture insulation.
When choosing a heater, you need to focus on its cost and climatic features. You should also take into account the complexity of the installation. The easiest way is to use roll materials, but everything that falls asleep requires the installation of a lag or screed. Ideally, for greater efficiency, insulation should be combined by laying them in layers.
And one more important point: do not strive to make the house absolutely airtight - this is the most a common mistake that leads to the fact that any finishing materials in such a "thermos" quickly collapse.
