Sex in the bath is exposed to moisture and heat, so his device must be approached very carefully.After all, the life of the entire structure will depend on the quality of laying the floor.Thus it is necessary to provide indoor bath water flow in a specially constructed drain hole, which makes the floor with a slight slope.Depending on the functional purpose of the room in the bath chosen material for the device sex.But in any case it is necessary to consider its insulation.Many novice builders did not know how to insulate the floor bath which opt for this construction materials.


Thermal insulation of concrete floor ↑

concrete floor is easy to maintain and durable.Most often i

t is made in the washing compartment.To start the device after you have made the drainage system will make the roof, glazed windows, install door frames and finish all the work on finishing the room.Since concrete is cool and slippery, the bath must be covered with a removable wooden bars.You can use these to mats of twigs or flooring made of wooden slats.

The diagram shows the construction of the concrete floor insulation:

How to insulate a concrete floor in the bath
A common layout and design elements of insulating polystyrene foam insulation floor
  1. foundation;
  2. slab made of concrete slabs;
  3. waterproofing layer;
  4. as extruded polystyrene insulation;
  5. concrete screed reinforced mesh;
  6. floor heating system and an adhesive layer;
  7. floor tiles.

One effective way of devices of this type of floor is laying insulation layer made of glass wool, expanded clay or perlite, between two layers of concrete.

called expanded perlite sand, which, being a light material has a low thermal conductivity.

Warming of the floor perlite
Thermal insulation floor in the bath can be carried out using perlite

Important!The room should be kept closed when working with perlite, otherwise it will be blown by the wind.

Procedure perlite insulation

1. Take two buckets of perlite and carefully mixed with one bucket of water.Then cement is added and the mixture was thoroughly stirred.Then pour another bucket perlite and pour not more than half a liter of water.All components are mixed again, and do so to the point until water is separated from the solution.It was this sign indicates that the mixture for laying the insulation layer is ready.

2. spread on a concrete slab with a thin layer prepared mixture, leaving her alone for a week to dry.

3. Once placed second layer of concrete solution.Insulating layer formed as a layer, it will last for many years.

Thermal insulation foam plates ↑

Using the latest foam material having a closed cell structure, allows for the most effective heat insulation of the floor in the bath.The special structure of styrofoam different almost zero water absorption, keeping for a long time its insulating qualities.Expanded polystyrene is not subject to water penetration, it is distinguished from other insulation materials having an open cellular or fibrous structure.Low thermal conductivity foam plates perfectly preserved regardless of the moisture and mechanical influences.This material is recommended for use as insulation in the brick baths.After all, brick is a conductor of moisture from the soil and the environment.

for insulation concrete floors are covered with tiles, laid on the leveled surface covering, use foams that have high compressive strength.Experts recommend using the following materials:

  • Styrodur - solid green plate, produced by concern BASF (Germany);
  • Natur-III-PZ - heat-treated ribbed plate;
  • Natur-III - compacted smooth plate;
  • Roofmate - insulating hardboard, painted in blue color;
  • Penoplex.

Environmentally friendly foam ↑

Materials used for thermal insulation of the floor in the bath must be environmentally sound.In this regard, extruded polystyrene fits perfectly.After the foaming of the material provided by ordinary carbon dioxide.This means that it does not present any hazardous gaseous reactants contained in the Freon.

foam suitable for use in the construction, because it can be cut with conventional tools.Thus, as a rule, one can avoid the waste, which affects the decrease of costs of insulation work.Weightless plate not aggravate any concrete slab or foundation structure.Horizontal stacking insulator is carried out on a perfectly flat substrate.Foams are not afraid of contact with the water, since it is not subject to biodegradation.

Insulationworks interior floor bath is carried out in several stages.

1. After laying the foundation, and the installation of a concrete floor slab waterproofing perform future floor.

2. Then laid insulation - Styrofoam plates.The thickness of this layer can be from 10 to 25 cm.

3. On top of the concrete floor slabs suit, using reinforcing mesh.

4. Tie glue is applied with a floor heating system, conducting ceramic tiles.

Warming of the floor and the walls and ceiling of the bath, allows the indoor minimal heat loss.

warm wooden floor ↑

During the construction of baths many master device is selected floor wood materials.Because it can not be compared with any tile environmentally friendly flooring made of wooden planks that can store heat for a long time.For such floors served as long as possible, without succumbing to rot, they should be properly prepared and be insulated.

As a material for the device plank floor bath is suitable fir, larch, pine and fir.

Important!Strongly advised to use the following wood: linden, poplar, aspen and oak.

Forms made of wood ↑

Wooden floors in the bath are of two types:

  • proceeding;
  • not leaking.

Leaking floors, on the basis of the name, allow the water to drain into the ground under the bath through the cracks between the boards available.These floors do not require large investments of material resources, as well as labor costs.However, they have a very big disadvantage.These floors - cold, so they recommend using in the southern regions.

not leaking floors have rough floor, which is laid insulation between the joists, to underpin finish.To arrange the outflow of water in the floor a hole that leads to the header, and then on the sewer pipe is displayed outside the baths in the drain pits or septic tanks.The pipe diameter should reach 150 mm, it will allow water to quickly leave the washing compartment.Do not leaking floors are made under the bias that allows you to not stagnate water.Currently, preference is given this type of wood floor in the construction of the baths.

How to insulate the floor bath
top of insulation "is not flowing" wooden floor in the bath is placed a layer of waterproofing, timber impregnated with antiseptics and flame retardants

All floorboards, lay in a waiting room and recreation room, covered with a special antiseptic.It will effectively protect the wooden floor from defeat by a fungus, as well as the beginning of the process to resist rot.For the flooring in the steam room use dried wood, which is processed by special trains are not subjected.Indeed, under the influence of steam to evaporate, which harm the human body.Well dried the floor during the operation does not progniet, only darker.

The figure schematically shows the construction of a wooden floor with insulation:

  6. extruded polystyrene foam - insulation;
  7. waterproofing layer;
  8. floorboard.

As the insulation at the device wooden floor in the bath can be used mats of mineral wool, fiberglass mats, slag, sand, expanded clay.

use of removable wooden floor ↑

Also today practiced in baths use of removable wooden floors, soaked boards which are removed, and in their place put dry.The process is quick and easy, because the board is not nailed.Soaked board is subjected to natural drying in the sun, or forced in special drying chambers.Then the replacement process is repeated.Thus, the extended period of use of the wooden floor.
