It's no secret that you can use sawdust as a heater.
Moreover - it's just a great alternative to thermal insulation boards, which are not cheap in building materials stores.
With the help of sawdust, you can insulate at least the whole house - from the floor to the walls, ceiling.
Here only sawdust in the pure state is impossible to use - they quickly get damp, and from the moisture they simply decay.
That is, initially they will need to be processed and protected from the negative effects of moisture.
How is the sawdust unit made( also of sawdust concrete) manufactured? For 10 buckets of dried sawdust, a bucket of sand and a half-bucket of cement powder is added.
All this is poured. .. no, by no means by water, but by a solution of boric acid, which will protect the resulting blocks from rot, bacteria and frost.
If boric acid is not added, the blocks after freezing - immediately turn black, lose their heat resistance.
Heat insulation of the floor with sawdust
To make the floor in the winter not so cold, first the self-made insulation from sawdust is made by hand according to the method described above. Nothing complicated in this.
Next - the blocks are allowed to "stand" for several months.
It's not hard to guess that in order to insulate the floor for the winter, it is recommended to do the blocks in the summer, and better - in general in the spring! They "crystallize" over time, turning into a monolithic cinder block.
You can also make sawdust with clay as a heater - this is the cheapest option!
That's only in addition to clay it is recommended to add a few kilograms of lime - so the construction will be more dense, respectively, the coefficient of thermal insulation of the blocks will increase.
The clay with sawdust is also mixed with a solution of boric acid with water( about 100 milliliters per bucket of water).
Sawdust with lime as a heater will last you much longer - at least 10 years!
How to properly place a heater under the floor? Just blocks, as tightly as possible to each other, fit under the boards.
In order to prevent moisture from accumulating on the blocks in the future, it is recommended to lay several layers of roofing material between the sawdust blocks and the floor itself.

As a last resort - and an ordinary polyethylene film, but it will not last long - just a few years, after which it will need to be completely replaced!
In order not to "suffer" with blocks, it is possible to make a heater as a chipboard( chipboard).
You just need to first find a suitable container for the plate.
Sawdust as a wall warmer is also used as blocks in the size of 100x100 centimeters.
What is the optimal thickness of the sawblocks you need to effectively insulate the floor? About 10-20 centimeters.
Of course, the more layers - the better, but also overdo it - there is no need.
10-centimeter layer of insulation from sawdust increases the thermal insulation coefficient of the floor exactly as much as the meter layer of brick does. But at a cost - 30 times cheaper!
The difference is significant!
Insulation for walls and ceiling
Walls and ceilings should be insulated with a material that is light in weight.
Fortunately, sawdust is not heavy, but here is cement, clay and lime with water - do not have a small mass! How to create a lightweight and heat insulation insulation?
The best option is to use the sawdust most of all.10 buckets of chips will require about 1 bucket of sand and 0.5 buckets of cement. All this is poured with two buckets of water.
As a result - it turns out 0.7 cubic meter of insulation. The optimum thickness of the slab is about 5-10 centimeters( to ensure that the weight per square meter is not more than 15 kilograms).
It is also worth recalling that the use of sawdust as a heater is also permitted during roof insulation. That's just first you have to mount a separate box under the shelter of the roof.
If a frame roof is used, in principle, problems should not arise.
A simple insert is made from the same plywood into which the sawdust block is laid. From the side of the roof or attic the ceiling is also insulated!
In this case, it is possible to use blocks, rather than a heat-insulating plate.
Special attention should also be given to how to make a heater from sawdust with. .. gelatin! This is also possible.
Sand is not used at all in this case, but just cement is added to the sawdust, you can have a little clay.
Do not add to the water of boric acid, but just about 200 grams of gelatin powder is spilled out. Literally within a few hours the resulting mixture thickens even in a warm room!
It turns out a soft block, which can be stacked under the roof. It does not dissolve in the sun, does not shrink, does not rot.
Well, finally, we should write that sawdust as a heater is no worse than a foam or a mineral wool plate.
Thermal insulation coefficient - almost the same, at the level. The cost - even if the sawdust is bought, the sawdust blocks will be much cheaper!
By the way, a heater of sawdust and cement will better isolate heat in the event that less cement powder is added.

But the less cement powder is used - the more foam blocks will be exposed to negative effects from moisture. Choose individually what you need more.
And what kind of sawdust as a heater will be better? Strangely enough, but those that have a larger size. And, of course, the harder the breed of wood - the more thermal insulation will be better.
The ideal option is the use of oak sawdust, but it is difficult to find them even in the Leshozes, and they are not cheap. But with their help you can even fully insulate the wooden house!
Even if the ambient temperature falls below 30 degrees below zero in winter, an oak sawdust warmer will save heat in your home!
If in a wooden house the walls are covered with gypsum cardboard from the inside, the sawdust can be laid between the walls and gypsum cardboard.
