Materials for floor insulation in a wooden house

Mineral wool insulation for floors

This material for thermal insulation has a number of positive characteristics that allow to speak with confidence about him as the best.

  1. Mineral wool has a high performance acoustic and thermal insulation.
  2. It is resistant to moisture and fire.
  3. Excellent retains its quality for a long time.
  4. It tolerates severe mechanical stress.
  5. Environmentally friendly.
  6. Inexpensive.
  7. High chemical resistance.

Mineral wool is produced in the form of solid plates or flexible mat. And he and the other type of well-cut, which is important when carrying out insulation works.

Important: during installation of mineral wool, take care that its foil side facing into the room, that is turned on.

Types of mineral wool

Styrofoam: scope, specificity

Expanded polystyrene is most often used for insulation of foundations, Basements, floors in wooden houses, as well as for thermal insulation of floor heating systems.

This material has the following properties:

  1. durability
  2. environmental friendliness
  3. high levels of biological resistance to various microorganisms
  4. high insulation
  5. stability of shape and volume
  6. strength
  7. the minimum level of water absorption
  8. Ease of use
  9. soundproofing.

Perhaps the only disadvantage of polystyrene is its high, compared with mineral wool, the value of.

EPS boards are used for thermal insulation of basements, plinths, wooden houses communications systems

Of course, these two types of thermal insulationmaterials can be replaced by others, for example, expanded clay or foam, however, it is polystyrene and mineral wool are recommended for warming wooden floors and they provide the most tangible effect.

A double floor system in a wooden house

During the construction of wooden houses need to immediately take care of that floor it was warm. Many experts recommend to use the method of "double floor".

It is clear from the name itself, you will have to double to do a flooring of boards, only the board will be different.

Driving insulation wooden floor

Driving insulation wooden floor

Draft floor made of uncut boards,which should be carefully adjusted to each other, so as not to leave any gaps. If get a perfect surface is not possible, you can seal the gaps with foam or plaster to cover them. Over boards stacked layer of roofing material, which will protect hardwood floors from the breeding of fungi and mold. Then poured a thin layer of sand (its height should be only 3-5 centimeters) and level it.

To the sand is not exposed to moisture, itshrouded with plastic wrap. Its thickness choose to face, but it is best to take the thickest, that is in the store. The film needs to be fixed with nails or a staple gun. Film can be used instead of a special material - penofol, which is a flexible polyethylene foil. This not only delays paroizolyator heat in the house, but does not transmit moisture. Stela he foil inside the premises.

Now you can start laying theinsulating material, which is pre-cut into pieces need size. The thickness of the insulation to pick and choose, based on the conditions of the area in which you live. So, for Siberia, the thickness of the insulating material shall be not less than 200 mm, and in Finland, after severe frosts in 2009-2010, the standard increased to as much as 400 mm. So consider!

Above the insulation fit chipboard, which are subsequently laid floor finishing.

Suspension insulation system

This technique is very similar to the system of double floors, with the only difference that instead of the sub-floor using a grid of line and you do not have to remove floor finish.

Lesko is necessary to take the thickest and durable that it can withstand the weight of a heat insulator. Insulationworks conducted by the basement.

With the help of nails needed to fix the linebeams. Pulls it should be so that the size of the obtained cells was not more than 20 cm, but in general, the smaller the cell size, the more reliable will stay warmer. Thus obtained, the space between the floor and the grid is filled with mineral wool or polystyrene foam.

The disadvantage of this method is the fact that over time the line was stretched and heat insulating layer slack, and his contact with the inner side of the floor will not be as tight.

But there is a plus - you will significantly save on building materials, because you do not have to buy boards sub-floor.

Warming of the wooden floor with carpet

Another method insulation of the floor in a private house without opening - insulation carpet. For these purposes Carpet - material which in their characteristics very similar to conventional carpets.

Carpet is laid around the perimeter of the room - this is the moment and distinguishes it from the carpet.

You can, of course, simply to lay these floorCoated and "sleep." That's just your dream is unlikely to be so peaceful. The wooden floor and the concrete is similar to that it has a slot through which the cold air comes out of the basement of the house. No carpet will not be able to protect you and your loved ones from this fresh draft.

To avoid such missteps, it is recommended to put a special heat-insulating substrate, which is sold in many DIY stores, and only then to lay carpet.

Needless carpet can be fixed plinth, but you can buy the glue that will secure the carpet in place.

Instead of carpet linoleum can be used on an ad hoc basis of jute or felt. This will keep the floor warm padded warm and the atmosphere in the house cozy and comfortable.

Modern technology in the service of man

With the development of progress appeared plenty of alternatives floor insulation. Now you can achieve a great effect with the help of special systems, called "warm floor". Insulate the floor in a private house has become easy!

This system is very easy to assemble and caninstalled directly on the joists and subfloor. It is absolutely safe for wood, so there is no fear of accidental fire and safely insulate your house in such a way.

There are two types of such systems:

  • In-floor heating system is rack and pinion type
  • In-floor heating system of modular type.

Both of these systems for water, that is, they heat the wooden floor by the water that constantly circulates through the tubes, which is the main design element.

The system uses modular components, modules, which are made of chipboard 22 mm thick. These sheets have small channels for tubes and plates, in which the water moves.

The system is rack and pinion type of tube and plateParticleboard fit between strips having a minimum thickness of 28 mm (thickness could be more). For tubes, there are grooves 20 mm wide. Thus, the entire system is rigidly fixed and can not worry about what the plate will move from the vibration space.

Both systems are installed the same way:

  1. Remove the old floor, including roughing, of course, if you had one.
  2. Around the perimeter of the room nailed a thick bar, which will act as a support for the future of the floor.
  3. Set the width of the pitch lags of 0.6 meters.
  4. We put the system of floor heating. With its installation wooden base on which are fixed all the tubes and plates, acts as the sub-floor, allowing little to reduce paper costs by saving on the purchase of boards.
  5. For a snug fit to the sub-floor floor covering specialists recommend lay between them a layer of polyethylene, which will perform the role of a kind of "cushion".
  6. Now you can mount any flooring - laminate, parquet or just lay board.

There is one important caveat: if you are planning on a wooden floor heating system to put a ceramic or stone tiles, linoleum or carpet, then before proceeding with the implementation of these activities should be made of the overlap gipsovolokonnyh plate. Such a shield is needed to:

  • coverage protection against possible deformation due to the heat;
  • uniform load distribution on the draft floor;
  • the uniform distribution of heat from the heating element to the floor covering.

Of course, such a pleasure worth decent money, but you get the perfect flooring that will be warm when you want it.

Drastic measures on floor insulation in a wooden house

If none of the methods does not suit ordoes not bring the desired result, one thing remains - to insulate the basement. Such work takes you a lot of time and effort, but your floor will definitely be warmer.

So, first you have to dig forperimeter of the house a trench depth of about 0.5-0.7 meters and a width of about 40-50 cm. In order to effectively protect the insulation material from rodents at the bottom of the trench is made of ceramsite concrete screed.

Now you can install the insulation sheets. This can be a foam or polystyrene foam. But their little set, we must also, so they stayed in place. To do this, use the special adhesive or mastic that dot spread over all the surface of the web. All cracks and joints between the sheets of insulation foam zapenivayutsya mounting.

Next, put on polystyrene foam glue (it will be more reliable), set the formwork panels around the perimeter of the house and fill the resulting space lightweight aggregate.

Thus, the heater is completely isolated from the external environment, rodents and moisture, and your floor from cold and frost.

Now you know how to insulate the floor of the house, but notrush immediately rush to the tools. Weigh all the "pros" and "cons", calculate the cost items, consider all the nuances and only then you can start working.
