When building a bath, it is necessary to think over its insulation. This process has a certain specificity due to the humidity in the room and high temperatures. You have to choose from a rather limited list of materials. One of the most suitable options is a sauna heater with domestic rockwool foil.
Description and properties of insulation
Insulation Rockwool Sauna Butts is a lightweight soft stone wool insulation board. The material is specially designed for sauna steam rooms. The slab is covered on one side with aluminum foil, which protects it from getting wet, which eliminates the need to additionally purchase a hydro and vapor barrier film. Heat, reflected from the foil layer, without leaving the room, which significantly saves fuel.
Rockwool for a bath has another significant property - environmental safety, which is very important for small rooms with high temperature and humidity. Stone wool from basalt rocks is a natural material that allows you to create a comfortable microclimate for humans.
Specifications
Heat-insulating material Rockwool Sauna Butts is supplied in slabs assembled in packs, packed in plastic wrap. The weight of the slab is about 10 kg, the size is 100x60x40 cm.
The insulation has the following characteristics:
- production material - stone wool of basalt rocks;
- thermal conductivity - λ10 ºC ≤ 0.036 V / (m · K);
- density - 40 kg / m³;
- fire hazard class - KM1;
- environmental Safety;
- lack of smell;
- long service life.
Thermal insulation properties work at temperature conditions up to +200 C.
Advantages and disadvantages
Insulation for a sauna with Rockwool foil does not require the installation of a vapor barrier, it does not get wet, because the plates have a layer of aluminum foil on one side. The material has a high level of sound and heat insulation, retains heat for a long time. Basalt stone wool is completely environmentally friendly for people and animals. Low flammability. The insulation is not suitable for food for rodents and insects. It is not susceptible to infection by fungi and bacteria. Another important advantage is the affordable price.
The disadvantages include the fact that the maximum efficiency directly depends on the area of the room - the material is intended for small steam rooms. Another disadvantage is the need to install the lathing for interior decoration, which entails additional costs for components.
Insulation installation methods
Care should be taken when working with this thermal insulation. Avoid contact with exposed parts of the body and respiratory tract. During installation, follow the instructions recommended by the manufacturer.
- On the surface to be insulated, a wooden or metal frame from racks is preliminarily constructed. The distance between them is 58-59 cm.
- Plates are installed with a foil layer between the frame racks inside the room. This is done so that the foil reflects the flow of heat into the room, and not in the opposite direction.
- The seams and joints of the plates are glued with construction foil tape so that there are no gaps.
- An air space must be left between the layer of interior decoration and the Sauna Butts slabs; for this, a crate is mounted on top of the insulation.
- Next, the interior of the room is finished with moisture-resistant building materials. The trim is attached to the lathing.
When insulating internal partitions, a 5 cm layer of material is enough.For external walls facing the street, it is recommended to use Sauna Butts 10 cm thick or two layers: the first - Light Butts Scandic 5 cm and the second - Sauna Butts 5 cm. so that the seams do not line up.
Application area
Despite the fact that the bath or sauna room is not constantly heated throughout the year, it must be insulated. This has its advantages. The supporting structure and interior decoration will be less susceptible to sudden temperature changes, which do not affect them in the best way. In addition, the steam room will warm up faster and cool down more slowly, which will save money on heating.
Thermal insulation of such a specific room has its own characteristics and requirements for materials due to high temperatures and humidity. Due to its operational properties, Rockwool for baths are widely used in thermal insulation of steam rooms. They can insulate load-bearing walls, partitions and even the ceiling. Due to its incombustibility, stone wool can be used where there is a high risk of fire.
In addition to thermal insulation of steam rooms, Rockwool insulation is used in other rooms. It is used for thermal insulation of roofs and attics, floors and basements. The material can be used not only on private premises, but also on production sites.
Analogues of insulation Rockwool Sauna Butts
Due to the nature of the room, a rather narrow range of materials is used to insulate the steam room in the bath. Instead of thermal insulation from Rockwool, you can use analogs similar in properties.
Building insulation Green Planet "Bath-Sauna" is a fairly new moisture-resistant breathable material that perfectly tolerates temperature extremes. The insulation is made of polyester fiber, therefore it is not subject to decay, environmentally friendly, hypoallergenic. Differs in ease of installation and increased service life. Supplied in the form of slabs packed in boxes. It allows you to keep warm in the cold season and prevents the room from heating up in summer.
Isover "Sauna" with foil is a fiberglass-based heat-insulating material. Marketed as lightweight air mats packed in rolls. Possesses high moisture resistance, low flammability. Thanks to the foil, it is not necessary to lay a vapor barrier film during installation. In addition, the foil layer reflects heat, which increases the indicators of thermal insulation properties. Isover "Sauna" is completely safe for the health of people and animals, in addition to its heat-insulating properties, it is soundproof. Has a long service life. Manufactured in accordance with European quality standards.
Foil thermal insulation Ursa is available for sale in the form of rolled mats. On one side, the material is covered with a foil layer. Produced on the basis of mineral fiberglass. It possesses not only heat, but also sound insulating properties. Most effective when placed horizontally, for insulation of ceilings, basements, attics, floors. Ursa is not flammable, the temperature of its application is from -60 to +270 C. It is completely safe for people and animals. Also, thanks to the foil coating, it does not require the use of additional vapor barrier.
