What insulation is better to choose for the floor in a wooden house?

Wooden houses require a more thorough approach to floor insulation works. It is necessary, first of all, to save the structure from rotting and fungus. Heated floor makes the house cozy, it is nice and comfortable to be in it.

Before proceeding to the insulation of the floor independently, it is necessary to become familiar with the types and features of heaters. As well as the algorithm of performance of work. This is what the article will be about.

Special features

Wood floors, unlike concrete, are much warmer. Wood is a capricious material and when building a house it is not always possible to achieve the desired effect. The ratio of the thickness and heat conductivity is often disproportionate, so insulation of the floors in the house of wood is simply necessary.

The possibility of warming the floor is not only in new homes, but also in the long-erected.

Warming the floor helps to maintain the ideal indoor climate and serves as a guarantee against such unwanted problems:

  • dampness;
  • the emergence and multiplication of mold;
  • the appearance of microorganisms and fungi that adversely affect the health of people living in the house;
  • high consumption of heat energy for heating the house;
  • damage and destruction of buildings.

Works on floor warming can be carried out independently. This will significantly reduce the budget. In the building stores a wide range of materials is presented, work with which is possible even without certain skills.

Thermal insulation of structures involves different types of work:

  • insulation of floors above the basement;
  • insulation of floors between floors;
  • insulation of the ceiling between the living room and the attic.

In each case, the materials are used not only to maintain the optimum temperature, but also for noise insulation. A well-insulated ground floor is a guarantee that the house will become comfortable for living.

Floor types

In houses of wood use two types of floors: concrete and wood.

The second option is divided into two categories:

  • floor board, glued wood;
  • parquet and laminate flooring.

Concrete floor can be made by hand without the involvement of specialists. There are two options for laying concrete: on the ground and on the logs. The most common is the first option.

All work is performed in several stages:

  • priming;
  • sand;
  • heat insulation;
  • waterproofing.

The next step is to fill the floor with a concrete screed. If you install a warm floor, then mount it is necessary at this stage.

The wooden floor, like the concrete pavement, also has several layers:

  • bulk floor (draft);
  • waterproofing layer;
  • thermal insulation layer;
  • fair coating.

If the installation of a floor heating system is necessary, then it is carried out at the construction stage between the finishing and draft coatings. Wood flooring is a natural material, and therefore environmentally friendly. When operating in the air will not be released harmful substances. This coating has an aesthetic and noble appearance.

What can be insulated?

Warming the floor in a wooden house is carried out in order to reduce heat loss.The most frequently used and inexpensive heaters are expanded clay and sand. Below is a list of other popular flooring heaters.

  • Mineral wool. The main features of this heat insulator are low thermal conductivity, durability, high noise insulation properties, moisture absorption. It is also worth noting that mineral wool is an environmentally friendly material.

In order to determine the quality of a product in front of you or not, you need to check its color. Mineral wool, made from natural raw materials, has a brown color. A product that uses a prohibited substance in its production will have a yellow tint.

This insulation is produced in plates and rolls. Rolled insulation is most common when used on large areas. Mineral wool is very convenient, while working does not require special knowledge and skills. Everything can be done by hand. The material is lightweight, breathable.

  • Polyurethane foam. Insulation is quite expensive. It will require not only the help of specialists, but also special equipment. The material in its properties close to the foam.But he will not stand the tie. They can warm the floor below. The average service life of such insulation is 30 years.
  • Expanded clay. The material is quite common. Expanded clay is granules of burnt foamed clay. The material has high performance properties, lightweight. But with all the variety of advantages, there is one serious drawback. Expanded clay absorbs moisture very well, so when using it, it is imperative to install waterproofing.
  • Sawdust is a bulk variant of insulation. Sawdust mixed with hydrated lime powder is used against mice: 8 parts of sawdust for 2 parts of lime. This insulation can be filled between rough and finished floors. The average thickness of the layer is 20-40 cm, depending on climatic conditions.
  • Izolon is polyethylenewhich has a foam structure. The thickness of such a coating is 10 mm. On one or two sides foil. Placed on top of cotton wool. And also used as a coating under the warm floor.

What is better to choose?

The wooden house can be put on the foundation and have a basement (basement), and can be located on piles.

Houses on stilts are in great demand among consumers. This is due to the fact that such a construction does not require a lot of time and energy during the construction and operation. There are also no requirements for the ground on which the building will be located. The choice of insulation for the house on stilts requires to take into account the design features. With the right approach, the house will be not only warm but also comfortable.

But with all the advantages there is a drawback: the house is located at a distance from the ground. The building is not protected by the basement and is subject to winds. In this case, it turns out that the house is protected from soil moisture, but the entire floor area is accessible to winds and frosts. In order for the house to please their owners, it is necessary to produce high-quality floor insulation.

Warming of a floor in houses on stilts is made in several stages:

  • Training. Before starting work on floor insulation it is worthwhile to ensure full access to the lags. This is done for the possibility of control checks. After the start of work will be impossible to inspect.
  • Rough floor. There are a lot of ways to create a subfloor, but builders more often use the traditional one.On the logs it is necessary to nail the timber, which will later serve as a support for the flooring of the boards. Lumber and logs are treated with special anti-rot and fungus agents.

But do not use the tools that create the film. This will not allow the tree to breathe, which will lead to rotting. Boards for flooring under the draft floor is also worth processing. This is necessary to increase the life of the material. When calculating it is worth considering the weight of the insulation that will be used. As a flooring, you can use plywood for light insulation. If, for example, polystyrene is used, then a reinforced mesh can be used to strengthen the lower layer. This will help distribute the weight.

  • Vapor barrier. Vapor barrier must be used to ensure that moisture does not fall on the insulation. For this it is better to use polyethylene or roofing felt. These materials belong to the economy class. When installing them, ventilation ducts should be provided. The vapor barrier must be on top of the insulation as well as on the bottom. This will not allow condensate formed during temperature differences to get into the materials.
  • Finishing floor. Finishing the floor - this is the final stage of floor insulation, which can also be a finishing coating. For this, absolutely any material can be used (solid wood, chipboard, plywood).

To make the house on stilts look presentable, as well as for additional protection from the effects of climatic conditions, experts advise to make an easy version of the basement.

Care for the insulated floor

Insulated floor in the house does not require special attention from the owner. Everything is as usual: dry and wet cleaning, airing the room. The only exception is the floor heating system. But here it all depends on the choice of the finish coating.
