When building a bath, they always try to thoroughly vaporize and insulate the room. The main obstacle to this task is the ceiling, through which some of the heat can escape. To reduce leaks, it is not enough to use thermal insulation materials; many other factors should be taken into account.
Requirements for the height of the ceilings in the bath
The purpose of the premises in the bath is different, because of this, the ceilings are built at different heights.
When determining the height of the ceilings in the bath, use the following guidelines:
- In the steam room an elevated temperature is always observed. The lower the ceiling, the faster it will warm up. The distance to the ceiling in the steam room is determined by the height of the tallest member of the family or company with the addition of 0.5 m on the swing of the arm with a broom.
- In the washing room the temperature should be kept at 37-39 degrees. The height of the ceilings is not regulated: the higher, the more air and easier breathing. The most common height in this room is 2.5 m.
- In the rest room the ceiling height is also not regulated, in this case it all depends on the design of the room. For example, a hipped ceiling is located at a height of more than 3 m from the floor.
- In the dressing room, the ceiling is built like in a living room.
Types of ceiling designs in the bath
Ceilings are built in one of three ways, depending on the purpose of the room.
False ceilings for a bath
They gained popularity due to the ease of manufacture. They are used for the installation of the ceiling in the steam room and washing room, but can also be used in other rooms. On the side of the attic, insulating materials are laid between the support beams of the attic floor to protect the room from loss of steam, heat and cold. The insulation is covered with boards on top. From the side of the room, the ceiling is sheathed with clapboard.
Advantages of a false ceiling in a washing bath:
- Simplicity of design, work can be done without carpentry skills.
- It is possible to use the attic room for storing household items.
- Ceiling repairs can be done quickly if necessary.
The disadvantage of this method is the use of a thick bar for the device of the ceiling in the bath, which must withstand heavy loads. For construction, expensive sawn timber with a cross section of at least 50x50 mm is required.
Panel ceilings in the bath
They look like a "trough" of boards. The width of the structure is 50 cm. A vapor barrier layer and insulation are placed inside the panel. Each panel is made separately and then fixed to the ceiling. The gaps between them are sealed with a moisture-resistant insulator, for example, felt with a layer of polyethylene. From below, everything is sewn up with clapboard.
The disadvantages include the large weight of the panels, which leads to significant loads on the supporting structures.
Panel ceiling advantages:
- High quality wood is not required, board trims can be used.
- It is possible to use the attic for storing bath accessories.
Floor ceilings in the bath
Used in rooms with a small area. The design is simple: the ceiling is formed by boards that rest on the load-bearing walls. The gaps between the boards are sealed with crumpled clay 2 cm thick. First, an insulator from steam is placed on top, and then a heater, which is covered with a croaker. From the side of the room, the ceiling is sheathed with clapboard. The negative side of this design is the low carrying capacity of the ceiling; only brooms can be stored in the attic.
Thermal insulation of the sauna ceiling
Before making the ceiling in the bath, choose a heater for it.
You can use the following heat insulators:
- Jute insulation is considered the best option for ceiling insulation. Does not rot, is not affected by high temperatures, maintains a healthy atmosphere in the building. It is a natural material without synthetic additives. For insulation of the ceiling, jute insulation with a thickness of 6 mm is used, the density of the material is 600 g / m. The fiber length of high-quality insulation is 2-3 cm.
- Mineral wool slabs and mats are also used as insulation. This lightweight durable material is considered a classic option for thermal insulation.
- Expanded clay is an inexpensive material, but it must be poured at least 30 cm thick, so the ceiling is reinforced with powerful beams. For expanded clay insulation, it is necessary to make a rough ceiling from boards, on which the insulator is poured.
- Glass wool, tow, felt, moss are also suitable. These materials allow air to circulate freely and are well sealed.
To insulate the ceiling in the dressing room and the rest room, you can use heat insulators made on the basis of plastic - polystyrene, perlite, honeycomb. In the steam room and washing room, these materials are not used.
Disadvantages of natural insulation:
- May be affected by moths.
- Dry quickly.
- Installation takes a long time.
- Only dry samples are used for installation, otherwise they will rot.
- Natural ingredients are often impregnated with chemicals that are harmful to humans.
Do not cover the insulation in the washing room with anything, otherwise it will not dry out. The design of the ceiling in a bath made of reinforced concrete slabs has its own characteristics. If the walls of the bath are made of bricks and the ceiling is made of concrete slabs, the insulation of the ceiling is carried out as follows:
- Fasten mineral wool 10-15 cm thick from the bottom to the slab in any way.
- Cover the cotton wool with aluminum foil.
- Along the perimeter of the wall, under the ceiling, fix the beams of 10x10 cm, which will serve as support for the lathing.
- Fill the lathing for the lining to the beams in 50 cm increments.
- Sew up the ceiling with clapboard.
- From the side of the roof on the ceiling, lay a layer of insulation 10-15 cm thick. Lay planks on top of the insulation, then the attic can be used to store bath utensils.
- It is not necessary to waterproof the attic floor; a waterproof material under the roof is sufficient.
- If the steam room and the washing room are separated by solid walls, another, cheaper vapor barrier material can be used instead of foil.
Ceiling vapor barrier for a bath
The best vapor barrier for the ceiling of a wooden bath is a foil vapor barrier material. This is an expensive product and is often only used when building a ceiling in a steam room. In other rooms, it is cheaper to use a polyethylene film with a density higher than 140 microns for vapor barrier.
In the dressing room and the rest room, where the temperature is low, roofing felt, glassine and roofing felt can be laid as a vapor barrier. These substances are not used to protect against steam in the steam room; when heated, they emit unpleasant odors.
When making a vapor barrier, use the following guidelines:
- The joints and seams of vapor barrier materials from above are sealed with adhesive tape based on aluminum foil.
- There must be a gap of 2 cm between the vapor barrier sheet and the finishing material. With this technology, the facing material will not be additionally moistened from possible condensation on the vapor barrier.
- The vapor barrier must not allow steam to penetrate to the insulation, otherwise it will collapse.
- It is forbidden to use a breathable film or membrane instead of a vapor barrier.
Materials for the ceiling in the bath
For lining the ceiling, wooden or plastic lining, boards are used.
Wooden lining for the sauna ceiling
Materials for the ceiling in the bath must have low thermal conductivity. Such properties are typical for linden, aspen, alder and some other types of wood. Wood sheathing is used for the ceiling in the dressing room and the rest room.
In the steam room, it is preferable to sheathe the ceiling with wooden clapboard, it better withstands high temperatures. Do not line the ceilings with pine or spruce planks. The resin released from the boards at high temperatures will drip onto the head.
Do not make the ceiling from chipboard and fiberboard. When exposed to heat and moisture, they release phenol-formaldehyde resin vapors.
Plastic PVC lining for the ceiling in the bath
Imitates wood, has ideal properties for use in a washing room:
- The tight fit of the lining seams makes the coating impervious to steam.
- The lining does not require an antiseptic coating, it does not rot.
- The sheets have simple geometries and connection points for easy assembly.
- A product with a cellular structure 5 mm thick, therefore, is considered a good insulation.
- The panels are strong enough to put mineral wool on top of them for insulation.
- The installation of the lining is simple, you can sheathe the ceiling in the bath with your own hands, even without having much experience in such work.
Combined materials for the ceiling in the bath
There are modern combined materials on the market that have the properties of a heater and a heat vapor barrier. They are sold in the form of slabs, fixed with nails or a stapler. Capable of withstanding 150 degrees. After installing the slabs, the ceiling is sheathed with clapboard.
The use of antiseptics to cover the ceilings in the bath
Be sure to cover the wooden ceilings in the steam room and the washing room with a special antiseptic for the bath, which protects the wood from fungus and insects. These products include the SENAGE SAUNA antiseptic and the Dulux Celco Sauna varnish. They can withstand temperatures up to 120 degrees and are odorless. The varnish also forms a smooth, durable film on the panels that protects the ceiling surface and makes it easier to clean.
In the steam room, ugly marks remain on the ceiling after splashing aromatic oils and water, sweating, so the smooth varnish film will make it easier to clean the surfaces. In other rooms, you can also treat the ceilings with an antiseptic if the panels are not made of coniferous wood. In this case, the resin will protect the material from moisture.
Do not paint ceilings unless they are designed for hot, humid environments. When heated, ordinary paints emit fumes that are harmful to humans.
