Warming the sauna or how to effectively keep the heat in the " dungeon " ?

Law "three barriers" for warming sauna

Careful warming saunas required not only because of the extra energy expenditure, to achieve the desired heat level in the steam room with poor insulation would be simply impossible.The money will go into the tube, and health is clearly not increase.What to do?Let us remember high-school physics!

Heat moves in the space of three ways:

• from hot to cold. heated object by touching the cooler, quickly divided with him energy.It is called the phenomenon of conduction, and to block the "route" of heat, it is necessary to protect the hot spring from the icy "embraces".
• Air. This method of heat convection movement boast itself.This is the fastest way to "fugitive", and if on the way he finds the slightest gap in the space box, then shamelessly escape outside.Hold it can only be carefully lifted her all the technical gaps, holes in the walls, ceiling and floor of the room.
• radiation. In this case heat passes through the surface of any naturally thicker "fence", the smaller the loss.The only way to return the heat wave back - on her way to substitute a reflecting mirror.

Warming saunas based on the simultaneous construction of three barriers to the propagation of heat in space.The only way to achieve optimal protection of the unique microclimate of steam.

What can be used for thermal insulation of the sauna?

Whatever reliable in its technical characteristics may be the box of a building, you have to make sure the internal insulation of the steam room sauna department.Since the insulating material will be operated in such extreme conditions, the requirements for its quality is quite high.

Insulation should be:

• natural;
• heat resistant.

In addition, under the influence of high temperatures it should not ignite and release party "flavors" or harmful gases.An important condition for the selection of the same is easy to work with the material: it should be easily attached to all the structural parts of the box room.

Under these strict standards ideal basaltic mineral wool, which operates quietly in a wide temperature range (-100 ° C to + 1000 ° C), has low heat conductivity (0.038 - 0.045 W / m × K), and refers to the groupfire-resistant materials.But for all its professional suitability it has two major drawbacks:

• «fear" of moisture and water;
• high cost.

If the first negative rule by protecting the mineral wool barrier hydro and vapor barrier, it's the second "but" things are worse.Or it is necessary to spend money well, or use of other available materials for insulation.

allowed to use expanded clay, wood chips and other fillings recipes, left over from our ancestors.The truth is they are only suitable for arrangement of floor and ceiling, but the sauna wall insulation is better organized with the help of modern technologies.There

latest insulation materials, specifically designed for the bath.By price categories are 25-30% more expensive than even the same mineral wool but win his client, thanks to the easy and trouble-free installation.

bath Ready "coat" Multilayer and immediately fitted with a mirror film and a necessary layer of cotton insulation, waterproofing membrane protected.They are placed close to the walls without the arrangement of the ventilation gaps.

Classical technology of internal insulation saunas

1. Floor Warming. done using an additional arrangement of the rough floor of the second-class board, which is nailed to the lower base of the log.This is the standard insulation of the floor circuit in a wooden house, where the resulting crevice technological laid mineral wool protected on both sides of the respective membranes.Only sauna insulator layer is thicker, and used as a vapor barrier foil or parchment paper.
2. Wall insulation.For vertical surfaces build "pie" consisting of waterproofing, mineral wool and vapor barrier.It is important to select the desired density cotton insulator (semi-hard, with the index of 120-150 kg / m3), carefully mats dock with each other, hanging them on the wall with a special mounting hooks.air gaps settling system by lathing, finishing stage - wooden clapboard cladding.
3. Warming ceiling .As the heated air accumulates here, the protection of this part of the sauna box should be especially careful.Puff standard materials: sheet pile board + steam + + mineral wool insulation, but that's the parchment paper or foil plank overlap (15-20 cm) and in two layers.The thickness of the mineral wool as compared to the insulation of the walls and floor sauna increased by 20% when used as concrete block, its layer should be at least 30-35 cm.

finishing touch optimal insulation of walls, ceilings and other structural parts of the sauna is a devicehigh nut for the front door to the steam room, which prevents the penetration of outside "lower" cold.In addition, the floor level is raised by 15 cm with respect to the adjacent pressure washer unit.
