Today, a bathhouse or a more modern option – a sauna – are attributes of a healthy lifestyle and are common almost everywhere. Many either from the savings of funds, or being in full conviction of their unsurpassed skill, are trying to organize the construction of a bath on their own. In principle, with the skills in the carpentry and furnace, the construction of a bath on its own is quite real and really will help save the family budget by reducing the cost of the estimate of work and materials. True, not all those who actually have these skills have, which is the cause of gross errors in construction and often inconvenience in the further use of the bath for their intended purpose. Everyone knows that if you put a fireplace incorrectly, then smoke, instead of going up the pipe, will strive for a room, so it will be very problematic to warm up. Something similar can be said about the construction of the sauna: if you are wrong to insulate the walls or make the stove, it is unlikely that you can achieve the necessary humidity and thermal conditions in the room. Most likely, the heat will slowly accumulate and leave very quickly, which is not at all suitable for the operation of the bath. Next, let’s talk about how to make a bath or sauna as warm -intensive and convenient to use. As a rule, walls in bath rooms are made frame or logs with a laying of an additional layer of thermal insulation from mineral wool. The steam room is sheathed with dried boards connected to the groove or quarter. A layer of vapor barrier is laid under such a casing: aluminum foil or polyethylene film. In a similar way, the ceiling is insulated, as a roofing material for which sheet steel, roofing material, etc. can act as a roofing material. In places of connection of the ceiling and walls, vapor barrier should be performed especially carefully. After accurate laying of the insulation, the frame of the bathhouse is covered with a layer for wind protection, which can be plywood, and then it is sheathed with spruce or pine boards to give the structure of stiffness. The boards are usually overlapped or a quarter to cover the walls from the wind and rain. The corners of the bath, as well as the boxes of windows and doors on both sides, are sheathed with platbands and boards. Unlike internal walls, the external ones are usually covered with varnish or stained. The most important element of any bath is the stove, and how soundly and efficiently it is made, largely determines the convenience of using the steam room. The constructions of the furnace can be welded from 5 mm sheet steel. For the convenience of transportation and installation, the components of the stove: the firebox, pipe and stoves can be made separately. For the manufacture and installation of a bathhouse for a bath, it is necessary to have extensive skills in the stove, so this work is often awarded to specialists. A competently designed furnace and thoughtful insulation of the room help to maintain a sufficient amount of heat inside the bath and not “heating air” save firewood and its own time.
