For a bath, the best material is a tree. Therefore, it is chopped from logs, built from a bar. The tree breathes, when heated does not emit any dangerous substances.
From ancient times, the design of the bath is aimed at maintaining heat, excluding moisture stagnation. It is the Sharub Bani that corresponds to these tasks. Now, to facilitate construction, they use a looped log. But professionals say that such material is more suitable for building cottages than for baths. Since the layer that in a natural way protects against moisture is removed.
To reduce the cost of building a bath, some prefer a frame method. Outside, facing, while the bathhouse looks like ordinary. According to this method, the bathhouse turns out many times cheaper. The walls are insulated with mineral wool, they turn out to be light and the load on the foundation is almost no. Due to such insulation, you can make a stove for a pair of lower power.
The floor in the bath is made wooden, filling in the lags, but recently it is proposed to make a concrete screed with the subsequent laying of the tile. But this leads to a rise in price, t. to. the screed will have to thermal insulation from the ground, and it is also recommended to make the floor warm.
The attic in the bath is required, you can even cold. Only ceilings must be insulated either with mineral wool or non -combustible bulk insulation. Do not forget that there must be vapor barrier to the insulation. If fibrous heaters were used, do not forget wind protection, to reduce air exchange in the thickness.
The roof can be used any, if only it does not break out of the style of the building.
And most importantly — thermal insulation of the steam room. Despite whether a bathhouse or a sauna, to reduce heat loss, except thermal insulation, it is recommended to use heat -reflecting screens. The foil will not only reflect the heat back into the steam room, but also prevent the thermal protection and wood. Do not forget that the screen should be continuous. For these purposes, the joints of foil or screen are glued with special tape. The main thing is not to lose sight of the fact that there should be a gap of at least 25mm between the screen and the internal skin. Otherwise, all the properties of the screen will be reduced to zero.
And finally, under any pretext, do not use PVC, polystyrene foam or ebonite for insulation, fraught with unpleasant consequences!!!!
