Thermal insulation of the ceiling in the bath - an important part of the process of resettlement of such premisesThermal insulation of the ceiling in the bath - an important part of this arrangement pomescheniyaSegodnya use different methods of insulation, applied and advanced materials, new technologies. But the insulation of the ceiling of the bath can take place in the old way, and the result will not be worse, if done correctly.


What a way of warming the ceiling in the bath is better

To work with the latest generation of materials is easy, but the insulation will cost a pretty penny. As for the old ways, the need to tinker seriously, but the repair itself will be cheap.

Warm bath foam can not be - at high temperatures, it releases harmful to human health, and if the material is close to the tube, so it just melted. Glass wool - too lousy insulation for the ceiling bath, though, because when you work with it need serious protection of the skin, respiratory system.

The most optimal materials for thermal insulation of the ceiling baths are: waterproofing film, basalt wool and aluminum foilThe most optimal materials for thermal insulation of the ceiling baths are: waterproofing film, basalt wool and aluminum foil

Materials for thermal insulation

Perhaps the best for the price-quality version of the warming today:


  • Waterproofing (film);
  • Basalt wool;
  • Aluminium Foil.

Thermal insulation and the thickness of the layer depends on the climate in which you live, what kind of bath roof roof (if the attic insulation will be different). Speaking on the average, the thickness of the insulating layer is equal to about 10 cm. However, steam rooms for this value increases and uses two vapor barrier layer to directly accumulate pairs.

How to insulate ceilings in the bath: the options

So it's worth to consider all of the standard options for warming.



The warm ceiling:

  • Bazalit. This elastic insulator with low density, made of basalt fiber. That it may be called mineral wool (rockwool). But not only the mineral wool basalt, but dolomite, limestone, diabase.
  • Izospan. This material in the two species, A and B. A Izospan considered protective insulator for walls and roofs against wind and condensate. Pave it outside insulation. In Izospan - vapor barrier, which protects the heater inside the saturation water vapor.
  • Expanded clay. These are porous clay capsules when firing over the clay do. To obtain a qualitative insulation, expanded clay necessary to lay out in a layer of 30 cm.
  • Sawdust. The material is cheap, but not the best for insulation bath. But if you decide to insulate the ceiling of sawdust, then a layer of sawdust correctly then covered with soil layer.
  • Foil. It is used indoors to protect it from moisture. Sheathe ceiling foil need to overlap, the joints of the foil is glued with a special aluminum tape (scotch).

Insulate the ceiling in the bath can be a foil, expanded clay, izospanom, sawdust or bazalitomInsulate the ceiling in the bath can be a foil, expanded clay, izospanom, sawdust or bazalitom

Popular and such material as a Cellulose Fiber. From the side it seems that it's just a kind of mineral wool, but it is a separate material - low-cost, environmentally friendly, and though his thin fibers, it perfectly holds heat.

Warming framing bath: materials for waterproofing

Requirements for waterproofing materials - high sensitivity threshold to high stress.

It can be:

  • ruberoid - is cheap, but its hard to mount, when heated will be unpleasant odor melting resin;
  • Parchment - it does not emit odors, friendly material, but it lacks the proper strength;
  • Foil - holds water, produces the so-called thermos effect;
  • Polyethylene - the most popular method for waterproofing having a light weight, flexible structure.

For warming bath require framing materials such as: polyethylene, roofing material and foilFor warming bath require framing materials such as: polyethylene, roofing material and foil

The best option would be a combination of several kinds of waterproofing. For soldering joints now use heat-resistant silicone-based sealants.


How warm bath ceiling with his hands, if no bath loft

The process is simple, but you need to go strictly on the steps.

Warming of the attic without a bath:

  • Fixing to the ceiling brusochkov with section five by five millimeters;
  • Step size = insulation material in the form of plates;
  • Batts surface;
  • Between the bars laid material - can lay pustotki mineral wool.

If your bathroom without loft insulation of the ceiling of the process it will not take you much time and moneyIf your bathroom without loft insulation of the ceiling of the process it will not take you much time and money

But instead of mineral wool can be used, for example, paper and foil. And then the process will be as follows: transverse wedges are mounted, and the foil is tensioned overlapped, it is attached to the bars stapler, and seams taped over tape.


Insulation bath with an attic

Hardwood floors a Russian bath will be different than that of the built-up structure.

And here lies the principle of warming in three steps:

  • Ceiling boards should coat the clay solution;
  • Slits spiked wood chips, but is first wetted with cement mortar, wherein the depth of filling not more than 20 cm;
  • Flooring is filled with at least two layers and preferably three.

Bath with loft insulation must be carried out efficiently and correctly, it is inconceivable that in a condensation bathBath with loft insulation must be carried out efficiently and correctly, it is inconceivable that in a condensation bath

This number of layers is dictated by the fact that the condensate will be formed in low layer thickness. If you do not have wood chips, straw, you can take. Clay, by the way, can solidify a month, but in the hot process will go faster.

If the attic room: how to insulate the attic

Features attic bath that hit the heat and water on the second floor is unacceptable, because the vapor barrier and waterproofing has to be impeccable.

If you have started the construction of a bath with a loft, or you already have such, take care of the quality intermediate floor.

Loft bath is necessary to make a good waterproofing and vapor barrier, as water vapor and shall not be exposed to the second floorLoft bath is necessary to make a good waterproofing and vapor barrier, as water vapor and shall not be exposed to the second floor

Many experts advise to use the old-fashioned way - clay and wood shavings. Taken clay chips and water, all mixed to a thick cream and poured on a rough floor attic. Top - waterproofing of roofing films, and bottom - steam. It can be soaked in linseed oil cardboard.

But this ancient method has drawbacks - the roof will be a tough, insulation and process long and laborious. Yes, and clay, as already mentioned, it dries long.

Thermal insulation of the ceiling in the bath (video)

There's nothing better than a cold winter literally jump into a hot bath, and in the summer on the contrary, from the heat - in the cool of the evening. To see the quality of each stage of construction and repair, and the bathhouse will long to please you.
