The technology of floor insulation with expanded clay in a wooden house, a bath

Underfloor heating with expanded clay is an excellent solution for supporters of the use of environmentally friendly materials in civil engineering.

Claydite refers to natural products, as when it is manufactured only clay and rocks including shale are used.

Under the influence of high temperatures and the rotational force of the furnace, various fractions of expanded clay granules are formed from said composition.

Subsequently, this building material that is harmless to health is used to increase the thermal insulation of the floor and walls of any premises, interfloor overlapping of buildings, warming of the attic in a private house and arrangement of the basement in the garage.

It is also difficult to find a replacement for expanded clay to warm the walls and floor in the bathhouse, which would not have toxic substances in its composition and would not release them into the air.

To date, existing claydite fractions are three types of building bulk materials:

  • Ceramsite sand - produced by the shallowest fraction, is endowed with a high index of bulk density;
  • Expanded clay-rubble - the result of crushed, pre-expanded and hardened clay;
  • Claydite-gravel - has oval and round granules. In the production process, the porous structure of each granule is enveloped in a layer of sintered clay material, thereby increasing the heat-insulating characteristics of the gravel.

Different types of expanded clay

Given all of the above, it's hard to choose which clay is better for floor insulation.

Specialists recommend mixing all three materials in the same proportions, which will allow the loose building material to fill the work surface with quality and not leave hard-to-reach places empty.

Thermal insulation of the wooden house floor

The comfortable microclimate in the wooden house is the result of the absorption of moisture by the walls,quality insulated floor.

In this case, the insulation of the floor in a private house will require the use of the following materials:

  1. expanded clay( small and large granules);
  2. ordinary sand;
  3. liquid waterproofing;
  4. wooden slats;
  5. steam and waterproofing material.

Also for work you will need a standard set of the builder, which includes:

  • level;
  • electric drill;
  • measuring tape;
  • hammer;
  • plane.

The technology of thermal insulation of the floor with expanded clay in a wooden house can be carried out according to the following scheme:

  1. The upper floor covering is completely removed to supporting structures called lags;
  2. On the base floor a layer of sand is poured, leveled and well tamped;
  3. Using the building level, check the horizontality of the sand cushion layer;
  4. Its surface is covered with waterproofing parchment or special liquid mastic;
  5. Then follows the marking of the foundation for the laying of expanded clay;
  6. Using a tape measure, the working area is divided into the same zones, which are later separated by wooden slats to a height of 100 mm;
  7. Each cavity is covered with a 10 cm layer of mixed expanded clay from large and small granules;
  8. On the top of the expanded clay, hydro and vapor barrier are used.

The thermal insulation of the underground in a wooden house with the use of expanded clay is completed by mounting the boards to the logs, which were removed at the beginning of the work.

If the main floor in the wooden house is on the ground, the technology of its insulation will be different.

After removing the main floor tree, gravel is poured over the soil.

The gravel layer becomes a kind of barrier coming from the earth to cold and damp air.

The gravel is poured and leveled with sand, the surface is carefully rammed. Over the pillows of gravel pour clay, level the level of the layer.

The claydite plane is fixed with a steel mesh, concrete is poured over it. After the concrete base has fully ripened, the floor covering is mounted.

The material will be supplemented by a thematic video about the warming of the floor in a private house.

Ceramsite floor insulation in sauna

If the floor in the bath for some reason failed to be insulated during the construction phase, its thermal insulation can be carried out in an already operated room.

Usually a concrete screed is poured in a washing room and a therma, as it is in these spaces that the air is constantly moist.

Wooden floors - destiny of the dressing room, locker rooms and rest rooms. Therefore, for each room in the bath the technology of floor insulation using claydite will have its own.

The insulation of the concrete floor in the bath is as follows:

  1. The concrete screed of the rough floor is cleaned of dust, if necessary, the surface is leveled, the bulges are removed and plastered;
  2. Several layers of rubber-bitumen mastic are applied to the working base. It is used to fix the waterproofing material on concrete. As a waterproofing, a strong polyethylene film or roofing material can be used;
  3. The waterproofing is laid with expanded clay, the thickness of the layer of insulation must be at least 10 cm;
  4. On top of the expanded clay, additional waterproofing material is equipped;
  5. Complete the process of floor insulation in the bath with a concrete screed, its thickness is about 3 cm.

More details about the insulation of the floor in the bath with expanded clay, the following video will allow.

We warm the floor with claydite in the garage

The most difficult thing in the process of warming the floor in the garage is the excavation, after which the floor insulation will be made on the ground and can have a thickness of about 45 centimeters.

The insulation work is carried out in the following order:

  • A waterproofing material is laid on the ground, usually a roofing material is used. It is better to overlap and with a turn along the walls of the garage;
  • Control horizontality of claydite filling allows the use of the metal profile as beacons, which must be set and fixed with a solution;
  • Over the waterproofing, the claydite is covered with a layer of 25-35 cm, the filling is leveled by the building rule according to the lighthouses;
  • The pointers are removed by moving on claydite with a plywood sheet. The grooves after the profile are also leveled;
  • At the next stage of the floor insulation in the garage, on top of the claydite cushion, a grid of reinforcement is built, the support of which is made of thick wire. The reinforcement process, as well as the casting of concrete, is carried out in parts using guide beacons.

Insulation of the floor on the balcony and with the claydite lumber

The insulation of the floor with claydite on the balcony and the loggia is a good way out of the situation when it becomes necessary to make the microclimate in the glazed rooms better.

Orientation for the future insulated plane on the balcony and loggia will be the correct setting of the beacons on a horizontal level.

Before laying the thermal insulation material, the floor surface is covered with a vapor-proof membrane, while its edges are released onto the walls. Subsequently, excess films are cut.

Beacons use a metal profile, which is fixed across or along the floor on a balcony or loggia, with a step not exceeding the length of the building rule.

Mounting the beacon guides allows you to divide the surface into segments, which are then covered with a heater.

The surface of the expanded clay fill should not exceed the plane on which the beacons are located.

Excess claydite is removed with the help of rules, using a tool, parallel to each other, beacon profiles.

If the floor on the balcony or loggia has a wooden base, a wooden crate is mounted on it. The finished frame has distinctive cells that are filled with expanded clay to the top of the beams.

In the next step, it is necessary to prepare a cement slurry or cement milks, which are carefully sprayed with a heat-insulating surface.

Cement milk promotes the formation of moisture-proof film on the expanded clay cushion and provides its strength.

Expanded clay on the balcony

Upon completion of the floor insulation on the balcony or loggia, the main floor surface is arranged, it can be 50 mm concrete screed or wooden planks.

Nevertheless, there are differences in the use of thermal insulation from claydite on the balcony and loggia.

The different temperature conditions of these two rooms require different thickness of insulation. So, for the balcony its layer should be a couple of centimeters thicker.

For heat insulation it is recommended to use two different sizes of expanded clay granules, while smaller grains are poured on top.

This approach will eliminate material shrinkage and subsequent cracking of the floor surface.

In addition, the use of two different fillers increases the strength and density of the clay-tiled floor.
