If you need thermal insulation for baths and saunas, then first you need to choose one of the varieties of materials that are presented today in the large assortment of building products market. It can be all possible blocks, canvases, as well as fabric elements.
Varieties of insulation materials
In the course of thermal insulation works , materials of increased stiffness, as well as rolled heat savers, are often used. You can apply, if you wish, a liquid insulation, which, after application, dries and takes the form of a polymer coating with an elastic base. You can use aluminum foil, which acts as an insulation and a reflector of thermal energy. It is used both in the washing department and in the steam room. As a protective material, you can use a rubber film, as well as kraft paper.
Thermal insulation for baths and saunas can be made in the form of a mixture of clay and sawdust, if you have to work with wooden structures. Similar alternative formulations are sold in stores today. It is worth paying attention to the fact that when warming the interior, it is not recommended to use roofing material and roofing, as these materials begin to release toxic components at elevated temperatures.
Heaters of natural origin
Thermal insulation for baths and saunas can be all kinds of. For a long time, the steam rooms were insulated with linnet, hemp, ice tow and woolen felt. These materials are able to guarantee excellent air exchange. If the bath is built of timber, then you can use red moss, which is used for internal caulking, it does not rot, it contains bactericidal substances. The same characteristics are possessed by cuckoo flax and sphagnum moss, these components become part of flax fiber.
Among their shortcomings, one can single out the high cost and duration of the insulation work. In addition, such heaters quite often become an object of interest for birds, rodents and moths. In order to combat these pests, the material can be treated with chemicals, but then environmental friendliness is not necessary. If natural insulation will be used for the ceiling of the bath, you will have to update it from time to time.
Specialists recommend using materials from flax fiber and jute, as they are resistant to the process of decay. It is advisable to use linen batting, jute felt, as well as mixed fiber. These materials provide excellent sealing, have a high degree of elasticity, which guarantees high-quality sealing of joints. And the price is quite acceptable.
When choosing materials for thermal insulation for a bath, you need to pay attention to quality, while it is preferable to purchase products made from flax and jute that perfectly cope with their tasks. However, it is worth considering that after carrying out insulation work using these materials, you will have to perform additional thermal insulation in a year.
Organic insulation
Organic materials are based on peat, as well as wood processing waste. Do not use peat, wood-shaving, as well as reed plates in the steam room, as they are not able to cope with the effects of elevated temperatures. Despite the fact that arbolite slabs and fiberboard are processed by fire-retardant mixtures during production, they are preferable to use for insulation not in the steam room, but, for example, in the locker room or dressing room.
Thermal insulation materials of mineral origin
If you are faced with a task in the process of which the sauna should be insulated with your own hands, then you can choose the most economical and versatile material based on mineral components. The assortment of stores presents mineral wool of all kinds in composition , based on slag and stone fibers. Such materials can be used for work in any room of the bath.
It is preferable to choose diabase, dolomite, slag or limestone wool. Using such materials, thermal insulation of the pipe for the bath can be performed, since these building products do not burn and perfectly prevent the spread of flame. In addition, they have excellent insulating qualities, and they can be operated for a sufficiently long time. However, they are not deformed and are able to undergo difficult conditions. Among their characteristics, water-repellent qualities can be distinguished.

If you use mats, based on stone wool, the timing of work is significantly reduced. In addition to simple installation, stone slag material has another plus, which is expressed in the fact that it is completely not interested in rodents. That is why basalt or stone wool often enough insulate the floor in the bath , supplying material to the lower floor, which is also dictated by the insignificant mass. Basalt cotton wool is today considered the most common material for bath insulation. It is necessary to choose the insulation that has a waterproofing layer. This is due to the fact that these plates are afraid of getting wet, after exposure to moisture, their insulating qualities deteriorate.
Specifications of mineral wool
This insulation is similar to fiberglass in terms of quality. But this material is more flexible, in addition, it is more convenient to use. But it is worth considering before acquiring that mineral wool has a not so high limit of resistance to high temperatures. However, the bath is unlikely to reach temperatures within 450 degrees.
Polymer heaters for baths
This material is practical and lightweight, in addition, it is quite convenient to mount. Synthetic heaters are resistant to moisture and significant temperatures. If you decide to carry out thermal insulation work, then you can use materials that are based on plastics. Among them, one can distinguish cellular plastics, polystyrene and polystyrene. If we talk about polyurethane foam, extruded and extruded polystyrene foam, then these materials are notable for their low weight and excellent heat-shielding characteristics. They are not capable of absorbing moisture and boast high strength as well as durability.
Use for thermal insulation of Penotherm material
If you need thermal insulation for baths and saunas, Penotherm is perfect for this, since it has established itself in the market of building materials. It perfectly provides heat preservation in the internal space of the room and eliminates noise. It is produced in the form of rolls. The basis of the Penotherm is extruded foamed polypropylene. Among other things, flame retardants are added to the material.
Penotherm is used as a vibration damping pad when it is necessary to equip a floating floor. This material has a flexible skeleton. The pores contain air that can absorb shock and all kinds of vibrations. This material is quite common today and is often used in construction and insulation works. If the bath has several floors, then it can be used when arranging floors. It is completely waterproof and has negligible thermal conductivity.
Finally
You, of course, can be used, as mentioned above, foil insulation for the bath. It will cost much cheaper, because in premises of this purpose there is not always a need to use noise insulation materials, overpaying for additional qualities.
