The company Rockwool produces insulation for saunas and baths "Sauna Butts", which are effective and have a democratic price. In this article we will look at the pros and cons of the material, we will talk about its technical characteristics and method of installation.

Bath wool “Sauna Butts” is an effective heat insulator, which:

• has a small proportion;
• has heat resistance;
• It is produced in special aggregates of own-made stone wool by Rockwool.

The material is designed specifically for warming baths and saunas. The big advantage of the product is an increased level of thermal insulation, thanks to which you can save on electricity and wood. On the one hand, the “Sauna Butts” cotton wool is covered with aluminum foil to improve the vapor barrier properties. The coating contributes to the reflection of heat inside the bath.

In addition to increasing the level of thermal insulation, Rockwool basalt wool allows you to save on the additional purchase of a vapor barrier film, whose application becomes unnecessary. The only thing that will have to buy in addition to the heater itself is the material for the air gap between it and the exterior trim. Another advantage of this heat-insulating product is fire safety, which is important for such premises.

The disadvantage of the material is the fact that its effectiveness depends on the footage of a particular room.

Technical characteristics of heat-insulating plates "Sauna Butts" are as follows:

• density - 40 kg per 1 m2;
• thermal conductivity - 10 0.036 W; constant;
• plates according to the level of flammability belong to the group “G1” and class “KM1” on fire safety;

Installation of insulation in the walls of the sauna is quite simple.

• First of all, you should install the products between the frame racks and at the same time leave a small clearance of 59 cm.
• Next, you need to heat the bath and install a foil layer of heat-insulating plate in a warm room.
• After that, it is recommended to carefully tape all seams and seams together. Self-adhesive tape must be made of the same aluminum foil.
• The final touch will be the installation of the batten between the basalt wool and the exterior finish. It is she who will provide the necessary air gap later.

To insulate external walls, you must install two layers of Rockwool products: Sauna Butts and Light Butts. The required thickness of both plates is 50 mm. For the implementation of increased thermal insulation it is recommended to mount the slabs following the example of brickwork.

When repairing a bath, you should think about the insulation of the chimney, which is most often in all other parts of the room in contact with smoke and is subject to ignition due to prolonged exposure to high temperatures. Basalt wool is perfect for this part of the steam room. For even greater performance, the brand offers Fire Butts. They are suitable when installing fireplaces.

To insulate the bath floor, you can choose one of two options depending on the material from which it is made. For a wooden coating, it is necessary to perform insulation on the logs with the use of a batten, for a concrete analogue it is installed on the ground. If a wooden floor is installed in the bath, stone wool is mounted in the structure between the lags, after which the waterproofing material is spread. Hydroprotection set overlap in the tile joints, after which they should be glued.Upon completion, the construction is covered with wooden flooring and trim.

In the case of a concrete floor using a different technology. First you need to install basalt wool of increased rigidity on the pre-primed surface. The second stage will be the waterproofing of the material, after which you need to produce a concrete screed and lay tile.
