How to properly insulate the floor in a wooden house with sawdust

Use for floor insulation of conventional wood shavings - this is one of the easiest ways to increase the level of thermal insulation. Sawdust has a number of advantages:

• relatively low cost of the material - sawdust less expensive than mineral wool or expanded clay;
• ecology - wood chips are absolutely safe for human health and life, do not cause allergies;
• mounting simplicity - in order to insulate the floor using sawdust, simply fill them evenly under the floor covering;

Filling the wooden floor with sawdust

• easily filled into hard to reach places - can insulate sawdust gap, failures and other places where it is impossible to install other types of insulation.

You can also use a variety of construction materials that have sawdust in their composition. These include opilkobeton, arbolit, Wood blocks and pellets from sawdust. But chips are mostly used in its pure form.

Subtleties use mineral wool

If the question arises, what is better for the floor insulation in a wooden house, the rock wool is one of the most popular options today. Firstly, mineral wool is the optimal combination in terms of price and quality. Secondly, it has many advantages:

• a low level of thermal conductivity, so that the heat loss in the house during the cold period is minimized;
• high water repellency, ie mineral wool is moisture, so this type of insulation can be installed in homes with high humidity;
• non-flammability of the material, which is much lower the risk of fire in wooden house;

The combination penofol and mineral wool insulation for better

• reasonable price - mineral wool is more expensive than wood chips, but cheaper than many other insulation materials;
• a high level of sound insulation. Insulate your house using mineral wool, you not only reduce heat loss, but also minimizes noise that penetrates into the house from the street.

A number of drawbacks derived from its material advantages. One of the key - it is a low water vapor permeability, which is why on a heater may accumulate water condensation. If you have planned a floor insulation using mineral wool, it is worth to take care of a good vapor barrier.

Floor insulation is performed using mineral wool between the beams

In addition, rock wool caking with time, and wherein the insulation is reduced. Therefore, when the insulation of the wooden floor below in a private home with the help of mineral wool should be installed several layers lapped.

Mounted mineral wool without gaps, and the top layer of a vapor barrier is laid on the layer of insulation with special sizing seams. This will protect the insulation from condensation itself on its moisture from the warm air from the house.

Proper installation penofol under wooden logs

Features of use penofol

Penofol used for thermal insulation of the floor relatively recently, and is still not very popular. It is a roll of material which consists of multiple layers of insulation and reflective aluminum foil. At warming the floor penofolom in a wooden house, you get the following benefits:

1. Simplicity and ease of installation - penofol can be mounted even without special skills in the field of construction.
2. High resistance to mechanical stresses - the material withstands high pressures, shocks and more.
3. The high density of the material, so that it can be installed not too thick.
4. At warming the floor penofolom, you do not have to install an additional vapor barrier, as this insulation material is not concentrated condensate.

2. Then he laid insulation, all seams and joints are filled with foam.
3. On top of the layer penofol mounted wooden joists. The distance between them should be at least 50 cm.
4. Between joists penofol fit again, and all the seams and cracks are filled with foam.
5. Top stacked wooden boards or chipboard sheets.

Penofol has a vapor barrier properties, which simplifies the work on the floor warming

Warming foam

Foam - this is another type of insulation, which in popularity is almost on par with mineral wool. From the latter he compares favorably with that does not absorb moisture, does not cake and, accordingly, does not lose heat insulation properties over time. In addition, when the floor insulation in a wooden house from the bottom by means of foam you get the following benefits:

1. A high level of strength of the material, it is resistant to mechanical stress.
2. The low level of thermal conductivity, ie, even a relatively small layer of foam prevents heat loss in your home.
3. Resistance to fire.
4. Resistance to various negative environmental influences. Foam successfully resists aggressive chemical environments, temperature extremes.
5. The foam is not afraid of rodents, so if you need a type of insulation for the floor in a wooden house against the mice, it will be an excellent option.
6. Decay or moldy.
