The sauna has a special temperature regime, so its walls should be very warm, and the whole structure is resistant to hot and humid microclimate. To keep the steam heat and protect it from rotting, you need to know what is better to insulate the bath and properly take care of the thermal insulation of its ceiling, walls and floor.
Effective warming of the bath is also necessary to ensure that the consumption of wood / energy is economical, warm-up - fast, and heat retention - long.
What insulate baths?
To date, insulation is carried out using a thermal insulation gasket, which is designed to protect from cold air room steam room. Due to the fact that the heat-insulating liner can not contact hot air, this material for insulation can undoubtedly be used at traditionally high temperatures of a room such as a bath.
So, the insulation of walls and ceiling is now realized with the help of semi-rigid mats and plates of mineral wool or glass wool. And for the interior facing of the waiting room, wood-fiber or particle board is most often used in combination with mineral wool and styrofoam plates. However, it is impossible to trim a steam room with such plates because these materials are easily ignited.
To determine what materials are needed to insulate a bath, first of all you need to know what its walls are made of (wood, frame, panel, brick) and what room you need to insulate (dressing room, steam room, rest room).
How to insulate the floor in a bath?
After the foundation of the bath is erected, it is insulated from above with mineral mats. To do this, before laying the floor on the ground lay a layer of slag or expanded clay, which should be 1.5-2 times the thickness of the walls. At the same time, all beams and logs must initially be dry for flooring.
How to insulate the roof of a bath?
To insulate the roof use mineral wool, polystyrene, glass wool. Heaters must be resistant to rotting and fireproofing. In addition to the traditional method of warming the floor of the roof (clay mud with sawdust), there are modern methods. One of these modern methods of insulation is the lining of the laths with roofing paper, pergamon or heaters. Insulate the floor of the attic and make a vapor barrier should be sure!
Before the roof is insulated, its structural elements must be protected from putrefaction, and also by means of fire protection. Be sure to impregnate beams and rafters with special flame retardants and antiseptics, since these elements are in a zone of high humidity and high temperatures.
How to properly insulate the ceiling of the bath?
Insulate the ceiling in the sauna is extremely important. Traditionally, the insulation of the ceiling of the bath is carried out in four layers - first there is a cladding, then a vapor barrier, a thermal insulation and a wooden flooring. As a result, the thickness of the insulation of the ceiling in the bath should be greater than the insulation of the walls. It is desirable to use a heater in 15-20 cm.
How to insulate the door in the bath?
On the existing door, nail a frame of bars with a thickness of 20 mm. Along the perimeter of the frame with aluminum nails nail the half-cut heater so that it protrudes beyond the edges of the beams by 15 mm. The frame with a heater is covered with a sheet of plywood of the same size and is nailed with small nails. So the heater will prevent the penetration of cold air into the room. This will protect the door of the bath from frost on both sides and keep it dry. As a heater use fur from old jackets, cloth of an old coat and stuff.
