The ceiling in the bath — device and decoration, how to properly insulate?


Ceiling in the bath - which is better for the steam room?

The creation of the correct microclimate inside it depends on compliance with the conditions for arranging the bath. The ceiling in the bath plays an important role. It must retain heat, not get wet from condensation and not lose shape from steam. The right choice of material, its competent phased arrangement are necessary for the durability of the ceiling and the good functioning of the bath as a whole.

Bath ceiling installation

The extreme conditions inherent in the bath oblige to a special arrangement of its internal surfaces. The peculiarity of the bath ceiling and the basic requirements for it are as follows:

  1. It must have high thermal insulation properties.
  2. In this case, the insulation must be reliably protected from moisture.
  3. The ceiling in the bath as a whole must be very durable.

As for the methods of installing a bath ceiling, there are three options:

  1. Panel, when the ceiling is mounted from prepared panels. They consist of load-bearing beams, hydro-, steam- and thermal insulation, inner cladding and an outer ladder from the side of the attic. These shields must be assembled in advance, after which they are tightly mounted to each other, and the joints between them are covered with an elastic waterproof gasket. It can be felt with foil or polyethylene lining.

  3. False ceiling in the bath. In this case, the lining of the ceiling with clapboard is first made. Then insulating layers are laid on it: steam, heat and waterproofing. After that, the ceiling is again sheathed with boards. It turns out that all the insulating layers are securely covered on both sides with a clapboard. Installation of such a ceiling is easy to carry out even by one person. The only caveat is the high cost of sheathing materials.

  5. Laminated bath ceiling. Its installation is even easier than in the case of hemming. Choose this option for small baths without attic space. The technology of its laying consists in the fact that, first, boards knocked into a shield are mounted on the upper edges of the inner walls, a layer of vapor barrier and insulation are laid on them. If you have chosen expanded clay as a heater, you must additionally provide wooden protective boards along the contour of the wooden flooring.

What is the height of the ceiling in the bath?

As a rule, the height of the bath from floor to ceiling is 2.4-2.5 m. The optimal height of the ceiling in the bath for you is determined as follows: on the top shelf of the steam room it should be comfortable for the tallest member of your family to sit in a bath cap without reaching while head to the ceiling. Another way to determine what height of the ceiling you need: to walk a person lying on the top shelf with a broom, there should be enough space for the person who holds this broom to fully swing the arm. And do not forget to add 10-15 cm to the measurements obtained for the shrinkage of a timber or wooden bath.

How to insulate the ceiling in the steam room of the bath?

Insulation of the bath ceiling is perhaps the main event. Knowing how to properly insulate the ceiling in the bath, you will save time on warming up the steam room. To heat the bath, you will need less fuel, and it will be easier to maintain the desired temperature in the process. Materials that are often used for this purpose:

  1. Mineral wool. The most popular insulation, and there are many reasons for this: it is durable, fireproof, it is easy to install and it keeps heat well. To insulate the ceiling in the bath with mineral wool, you will need rolled basalt wool with a thickness of 10 cm.
  2. Penoizol. A more economical option compared to cotton wool. It also holds heat well, filling all the cracks and voids, while being an environmentally friendly and completely safe material. Minus penoizol — the impossibility of local repair of small sections of the ceiling. It will take complete removal of the insulation, which is a laborious process.
  3. Expanded clay. Lightweight granular material that holds heat well. For a high-quality thermal insulation effect, a layer of at least 30 cm is required.
  4. Sawdust with clay. The most budget option, but very laborious. The mixed clay is laid in a layer of 3 cm on the flooring from the side of the attic. When it dries, wood shavings or sawdust are laid on top and everything is covered with dry sand. It turns out cheap, reliable and environmentally friendly thermal protection.

Bath ceiling waterproofing

Hydro and vapor barrier of the ceiling in the bath is an equally important stage of construction. The vapor barrier material is placed under the insulation, that is, on the boards between the ceiling beams. The waterproofing material is laid on the insulation from the side of the attic. Only such a sequence of layers provides comprehensive protection of the insulation from moisture and steam, prolonging its service life and maintaining its properties.

How to process the ceiling in the bath?

If everything is clear with the sequence of layers, then the question regarding how to cover the ceiling in the bath so that the waterproofing is at the proper level remains open. Experts recommend using the following options as a waterproofing material:

  1. foil material. It is easy to attach it to the beams with a construction stapler. It reliably protects from moisture and at the same time its cost is quite acceptable.
  2. Polyethylene film. You need to choose the most dense and durable. When installing it, it is important that all edges and joints are securely insulated.
  3. Thin concrete screed. An extreme case, if you need to insulate a small bath roof without an attic.

Bathroom ceiling decoration

Often for finishing the ceiling in the bath, options are used with clapboard made of linden, cedar, larch, aspen and other types of wood. This natural material has healing properties, increasing the benefits of being in the steam room. In this case, you need to monitor the quality of the wood. It must be well dried, hewn and sanded. It should not have nicks and knots.

Stretch ceiling in the bath

Thinking about what kind of ceiling to make in the bath, some stop at PVC stretch fabrics. So that the film does not suffer from temperature changes and adequately resists high humidity, you need to choose a particularly durable material for the stretch ceiling. At a cost, it will be more expensive, but you will end up with a beautiful and durable coating that will hide all unsightly communications and ceiling irregularities. The only point — do not forget to equip the bath with an exhaust hood.

Ceiling in a bath from a bar

The ceiling in a classic bath is often made using natural wood timber. When the whole bath is made of wood, it is also logical to finish the ceiling in the steam room with similar material. The bars in this case are used for the construction of a panel ceiling. They play the role of load-bearing structures, to which all layers of heat, hydro and vapor barriers and finishing materials are attached.

The ceiling in the bath from the lining

The most common material for the ceiling in the bath is lining. Their other name is cladding panels. This versatile finish is easy to implement. The ceiling, trimmed with clapboard, is breathable, visually it looks even and beautiful. After covering the ceiling, the lining does not need to be processed with anything. Stain, varnish and other paints and varnishes, when heated, will evaporate compounds harmful to health into the air.
