The technology of floor insulation in a wooden house

The warming of the floor in a wooden house is one of the most important stages in the construction process.

It is from the bottom, through the floor of the first floor in the old private house, the main part of the heat leaves, since it is closest to the ground.

The first floor of a multi-storey building needs at least as much insulation.

It is not surprising that the owners of such houses are wondering how to properly insulate the floor with their own hands and what construction materials are used for this?

All turn-based technology with photo and video will be described in this article.

Even for an unprepared person to make the right insulation of the floor with their own hands will not be a big deal and skill. It is more difficult to choose a warming material, in this we will help you to understand.

Floor Insulation Technology

The technology of laying insulation for a wooden floor is very simple, it can be easily done by hand without privtreatment of professional masters.

Thermal insulation cake consists of: heat insulator, vapor barrier, floor covering. This method is applicable for private houses and cottages, and for residents of the first and second floors.

The following work steps are carried out:

• Building lags are mounted below;
• The lining boards are stacked along logs;
• Insulating materials between lags are being installed. The insulation must be placed as tightly as possible, all cracks should be covered with a mounting foam;
• Installation of the vapor barrier over the insulation layer. It is fixed directly on the lags. Places of joints and lapping should be covered with foil tape;
• Installation of a wooden covering;
• Finishing the floor.

A warming pie should be used individually for each house, such factors as: climate, thickness of the future insulation, floor of the house.

Warming of the floor on the ladders

This method of installation is used very widely, because of its simplicity, efficiency and durability, it will not be difficult to do the work with your own hands, when you thoroughly familiarize yourself with the video and photos presented in this article.

The method of lag warming is especially widely used by people living in a private house and for residents of the first and second floors.

Warming of the floor on the lags is correct to produce this method. From the bottom are mounted wooden logs, between which it is necessary to lay the boards close, on which the laying of the insulation layer will be carried out.

After the heat insulator is laid, it is necessary to install a hydro- or vapor barrier.

This is especially needed on the first floor with a basement room below to protect it from moisture, with thermal insulation with mineral wool or eco-wool. These measures are also relevant for the second floor of the house.

For a vapor barrier use both special building materials and a simple polyethylene film.

Then the wooden floorboards are mounted, on top of which it is possible to finish.

The main advantage of warming on the lags in a private house is the simplicity of installation, which is almost everyone's power.

In the same way, the floors of the first floor are warmed, the heat loss of which occurs through the basement.

Materials used to insulate the wooden floor

The insulation of the floors in a private and high-rise building is made by such building materials:

• with mineral wool;
• eco-friendly;
• with expanded clay;
• with sawdust;
• isolone;
• with penofol;
• polystyrene foam;
• with penoplex;
• with expanded polystyrene.

We will tell you more about these insulation materials in more detail below.

Warming of the floor with mineral wool

Mineral wool is a building material obtained by using fibers of rocks, glass or slags.

Advantages of using mineral wool:

• The main advantage of mineral wool is its incombustibility, it can be used as a barrier against possible fires;
• excellent thermal insulation properties;
• Strain resistance;
• high resistance against the appearance of mold and fungal foci;
• is environmentally friendly;
• light weight, simplifying the installation yourself.

As drawbacks it is possible to single out:

• wetting at hit of a moisture, at a constant contact with a moisture loses the heat-retaining properties;
• glass-bound structure complicates the installation process;
• is not vapor permeable.

Process of laying mineral wool

When using any building insulation layer, a certain installation scheme is observed, which must be adhered to.

So, when using mineral wool, you need to observe the important stages of laying, as shown in the video:

1. Preparation of the bottom layer of the skin - usually for this, a solid board board is installed from below;
2. Laying the waterproofing layer - this is an obligatory stage of work, necessary to prevent moisture from entering the minnow;
3. Laying of mineral wool - at this stage it is necessary that the layers of cotton wool are laid on the logs close to each other, eliminating the appearance of gaps;
4. Installation of vapor barrier layer;
5. Installation of a wooden floor with a gap between it and the vapor barrier, which provides ventilation.

Warming of the floor with an eco-wool

It is not necessary to write off the ecowhat from the wide choice of building heaters, it can still be considered the most suitable material for the warming of wooden floors in a private house.

Advantages of using eco-wool:

• ecology - consists of waste paper and boric acid salts;
• does not form any gaps during installation, which must be closed;
• does not form rust when in contact with metal surfaces;
• does not shrink under vertical load;
• can be used as a soundproofing, which is especially often used for the second third, etc. floors;
• protects against the appearance of mold and fungi;
• good vapor conductivity;
• is fireproof.

When installing ecowools, the second layer of vapor barrier is not necessary, thanks to the porous composition it has good ventilation. The moisture from the bottom and from the room to the ecowool does not stagnate in it.

Therefore, the insulation keeps heat-retaining properties for a long time. The first, second floor is also recommended to insulate with this material.

The insulation of the earthenware floor is made as follows:

1. The first step before beginning the laying of the thermal insulation layer is to clean and primer the surface on which the ecowool will be laid out;
2. The second stage - laying ecowool on the logs, as in the photo, after which it is slightly rammed. A wooden floor can be mounted on top of the thermal insulator. If this is the first floor, then first you need to lay a layer of waterproofing.

Warming of the floor with expanded clay

Ceramsite is a porous ball obtained by burning light alloy clay. Thanks to its good heat-saving properties, it has been widely used in construction for several decades.

Advantages of using expanded clay:

• is environmentally friendly;
• strong;
• high heat-retaining properties;
• durability;
• soundproofs the ground floor;
• is not flammable;
• is frost-resistant;
• is light;
• is easy to install;
• inexpensive.

The minus of use is one - it does not have resistance to moisture, it does not dry out when saturated with moisture.

The first step in the insulation of the floor with claydite is to lay a layer of waterproofing, for this purpose it is possible to apply a roofing material, then the claydite insulation is covered with a layer whose thickness should be 10-15 cm.

A layer of a vapor barrier is laid on top of the heater - this is seen in the photo, in combination with expanded clayit is recommended to use a foamed vapor barrier, such as penofol.

The floor boards are also covered with floorboards. Layout of the layers is shown below.

When warming the plank floor for the first floor, under which there is a basement, before laying the claydite you need to pour a layer of sand. This is also true for residents of the second floor.

Heat insulation of the floor with sawdust

This method has been used for a very long time, but with a modern choice of a huge number of types of insulation is almost not used, especially if your floor is not the only one in the house.

Sawdust is obtained as a result of sawing and processing of wood.

Advantages of using sawdust:

• availability;
• low price;
• environmental friendliness;
• good thermal insulation properties;
• lightness.

Disadvantages of this material:

• are prone to fungus and mold;
• dry up and heat-retaining properties are lost;
• create a favorable habitat for insects and rodents;
• is flammable, even a small spark when the material is dry is sufficient to ignite it;
• is short-lived - this coating will have to be changed after 2-3 years.

When insulating with sawdust as the main material, it is necessary to make a pie, the first layer of which will be a roofing paper or a polyethylene film on which the sawdust is laid with a layer of not less than 15 centimeters, the film or any other hydro-vapor barrier will again be laid on top.

To date, in addition to the known sawdust for a long time, they use insulators based on them, impregnated with special compositions that are resistant to fire, such materials can be used on the ground floor.

Price they have higher, but the advantage compared to conventional shavings is huge.

Insulation of the floor with the insulator

The building material isolon is one of the most common modern insulants. One of his unique abilities is to reflect heat back into the room, not letting go through the floor outside.

Insulation of insulation can be any floor, and then the heat does not exactly leave your room.

Pros of using isolone: ​​

• efficiency;
• is used in private houses and on each floor in high-rise buildings;
• is environmentally friendly;
• is waterproof;
• is non-flammable;
• is durable;
• light weight - provides ease of installation;
• soundproof.

When using the insulating material as a thermal insulation material, the use of an additional vapor barrier layer is not necessary, which certainly is also an advantage.

At the first stage, it is important to clean the surface of dust and dirt, you can apply a primer layer that isolates the remains of dust.

Video:

When laying an isolon, it is necessary to monitor its fit, it must be maximum, and there should be no gaps and slots between the lags and the heater.

For fixation, it is best to use a special double-sided adhesive tape. The installation must be done by the foil side outward to the room.

Thermal insulation of the floor with

Advantages of using foam:

• lightness of the material, facilitating ease of installation;
• retains heat well;
• is moisture resistant;
• soundproof;
• longevity - the material is not rotted, does not degrade and does not deform with time;
  low price.

Video:

Disadvantages:

• is unstable to fire;
• during combustion gives off acrid smoke;
• is prone to the appearance of rodents;
• does not tolerate the constant presence of moisture, it requires a ventilated space.

When the floor is insulated by lag, the foam sheets are cut to the desired size and laid between them. Joints, cracks and gaps should be filled with mounting foam.

It will be correct to apply a vapor barrier layer over the foam. First floor to insulate with such material is not recommended.
