How to sheathe the ceiling in the bath

As you know, special requirements are imposed on bath buildings of various types, in accordance with which their ceilings should have good heat-saving characteristics. In addition, they must be reliably protected from the effects of dampness and moisture (good vapor barrier is required), and also have an adequate margin of structural strength.

In our article we will tell you about how to sheathe the ceiling in the bath and how to make it warm and durable, spending a minimum of effort and money.

Once the bath room box is ready, you can immediately proceed to its trim. As for the bath ceiling, its finishing can be done in three different ways, each of which has its own individual characteristics and differs from the others in its price. The list of well-known and proven techniques includes:

• use of wooden boards or panels;
• arrangement of the flooring ceiling;
• production of a ceiling type

As can be seen from the above list, all known options for finishing ceilings in the bath involve the use of lumber, which usually have a number of additional requirements. First, the wood must be completely dry. Secondly, the material for covering the ceiling should not contain excess resin.

Note! Any wood material requires treatment with special antiseptic substances that reliably protect it from destruction.

Shield ceiling

For the arrangement of a panel (panel) ceiling, ready-made panels, knit together from an edged board, which is knocked down on two crossbars made of bars with a section of 40? 40 mm (50? 50 mm), are used. The shield is additionally reinforced along the perimeter with a board not less than 100 mm wide.

Then a layer of vapor barrier is mounted on it, which usually consists of either roofing material or plastic film or wax paper. On top of the vapor barrier protection is placed a layer of heat insulator (basalt insulation or glass wool). And already on top of the heat insulator is mounted a layer of waterproofing, consisting of a conventional plastic film.

The shield prepared in this way is sewn on top with a cut board with a thickness of about 20–25 mm, and a sheathing from a bar is filled on the bottom. The finished panels are then laid on the beams of the ceiling of the bath structure.

Upon completion of all these operations, the shields fit as closely as possible to one another. Thermal insulation made of felt wrapped with plastic wrap is laid in the free niches between the batten rails (in some cases, foil polypropylene is used as insulation). On the side of the ceiling, a vapor barrier film is attached to the panels, which is subsequently trimmed with the finishing material of your choice.

The advantages of such a composite construction should include a significant saving of wood material, since any “illiquid” sawn timber left over from the main construction works can be used to assemble boards.

The disadvantage of shield constructions is the considerable weight of the finished blocks, which forces the contractor to involve additional workers in the work. Some craftsmen are trying to make semi-finished panels, that is, frameworks of shields without filling (insulation, waterproofing and flooring) and put them alone. But it will still be safer to mount panels in a company of two (or better of three) people.

Flooring ceiling

Flooring ceilings (due to the limited length of the board used for the installation) are usually installed in adjacent small rooms combined in a common space. When constructing ceilings of the flat type, it is allowed to lay the boards directly on the brick piping.

Note that the thickness of the board used for laying such a ceiling should not be less than 50 mm. The working width of the span between the support beams is limited by the size of the board (not more than 2.5 meters). It is clear that such a ceiling does not have a high bearing capacity and does not imply the arrangement of an attic room.

The analysis of the above data allows us to conclude that the main advantages of the floors of this type are the simplicity of their installation, the relative cheapness and high assembly speed.

Sewing потолок

The filing of the surface of the ceiling of one or another type of finishing material is considered the most common option for finishing ceilings in the bath. The advantages of this method include the relatively low cost of used wood logs, as well as relatively low labor costs.

Once again, we note that before starting work, all the wooden components of the future ceiling must be treated with a special antiseptic composition. In the absence of this substance, you can use ordinary linseed oil or primer deep penetration.

The specifics of the arrangement of the ceiling hem are as follows:

First, the so-called draft ceiling, which is assembled from simple (unedged) boards, is fixed on the floor beams, fixed on the lower edge of the beam using ordinary screws. In the process of trimming, the boards are tightly fitted to one another and (after closing the entire inter-gully space), they are covered with a vapor barrier. At the same time, the vapor barrier film is laid between the beams in strips of a certain width with a slight overlap (about 10 cm).

Fixing the film on the ceiling by using a construction stapler or small nails. Between the beams, the plates of the heater chosen by you (mineral wool, for example) are laid. When laying insulation, it is necessary to ensure that a clearance of 3–5 cm, necessary for ventilation of the ceiling space, is maintained up to the upper cut of the beam.

Regardless of the method of ceiling arrangement chosen by you, its covering can be made using the material that is most suitable for a given room.

At the end of the topic concerning the choice of material for ceiling lining in the bath, the following should be noted:

1. The most common material used for covering bath ceilings is traditionally wooden edged board. In addition, it has been proven that for extreme bath conditions such tree species as aspen or larch are best suited.
2. The main condition for the suitability of the finished material for plating is the absence of any noticeable flaws (large knots or microcracks).
3. The most attractive wood flooring option, familiar to most of the interested users, is, of course, lining.
4. Lining made from selected pine is considered to be an environmentally friendly building material, which has excellent bactericidal properties and is able to bring to the environment a sense of coziness and comfort.

When choosing a material for covering the ceiling, pay attention not only to the properties of the material, but also to the possibility of using it for your bath.
