How and what to insulate the roof and the ceiling in the bath: modern and traditional methods

During the construction of the bath is necessary to observe a number ofrequirements and rules. Thermal insulation of the roof and the ceiling should be carried out taking into account the structure of the nuances. In the bath needed a good steam and heat insulation, especially the roof and ceiling, as hot air tends to rise. Therefore, at the stage of construction is necessary to achieve the maximum conservation of heat in the steam room at the same time there is no condensation. After all, what is rarely bannomu lover will delight large drops of cold water, falling from the ceiling on a hot body. No less important is the question of how to insulate the roof of the bath. That's what we will discuss in this article.

Warming bath roof

The better to warm

If the room is only used for its intendedpurpose, particularly to insulate the roof is not necessary. It will be enough high-quality thermal and vapor barriers ceiling of the room and spread out on the tar paper roof sheathing before decking roofing. Comprehensive insulation of the roof is required if you are going to use the space under it as the premises for the storage and drying of brooms, bath equipment, clean linen.

Insulation for the bathhouse roof

One type of heaters intended for the roof bath - mineral wool with foil side

Modern building materials market is richvarious heaters. Usually I use foam, glass wool, mineral wool and such materials as RokWool and URSA. Most popular found plates "Penoplex" that can withstand temperatures from -50 ° to + 75 ° (because of this you can not use for steam). This material has a number of advantages:

  • durability;
  • uniformity;
  • moisture resistance;
  • ease of thermal insulation;
  • strength twice as polystyrene.

Besides the use of vapor barriers Penoplex eliminates the problem, as it does not completely absorb moisture.

Of the variety of materials is required to choose the most suitable to suit your preferences and financial capabilities.

Interesting: there are folk ways to warm bath, for example, coating the roof with clay with sawdust or the use of a cane. And in the second method, when properly laying the stems guaranteed high protection from rain and snow and excellent vapor barrier.

Paro - and waterproofing

Before the start of roof insulation all its elementsyou need to thoroughly process the compounds from rotting and the means protecting from fire. Rafters and beams are also necessary to impregnate with antiseptics and flame retardants. As a waterproofing material commonly used membrane film serving as a barrier to some water that can penetrate even through the smallest coating defects. The film serves as waterproofing, stretches to the rafters before installing the battens, and serves a vapor barrier - between the linings and ceiling insulation.

Flooring film freely and without tension, withoverlap equal to 15-20 cm. Between a fabric glued shut. This will help prevent the appearance of stretch marks and breaks when the temperature deformation of the material.

How to insulate a roof bath

The most popular a heater for sauna roof considered a basalt fiber (mineral wool). It has remarkable thermal insulation properties and is absolutely natural material. When mineral wool insulation of the roof is necessary to prepare a heat insulator layer consisting of two rows of desyatisantimetrovyh insulation, laid in a staggered manner. Already finished layer is located in the roofing pie.

Warming bath roof from the attic

How to insulate the roof from the attic bath with mineral wool

The main advantage of this method - Highreliability and the absence of thermal bridges resulting from the overlap joints. Of course, the high cost of such a method is different, so some builders are trying to save, replace the insulation on desyatisantimetrovyh pyatisantimetrovym and further protect the roof laying a double layer vapor barrier film.

Another cheaper way is to useinstead of basalt fiber foam panels, but due to the release of poisonous when heated phenol vapors can use this method only for external insulation.

Materials and Methods ceiling insulation

Thermal insulation of the ceiling is necessary because it provides:

  1. The accumulation of vapor inside the premises doubles.
  2. The protection of roof and attic from moisture.
  3. Absence of condensate on the ceiling.
  4. Saving heat.

What to use for insulation device

So, how to insulate the ceiling bath? There are many modern heaters are thin heat and vapor barrier, consisting of a layer of insulation and foil. But they alone can not cope with the condensate. To resolve this problem, it is necessary to lay another layer of insulation, as that can be used:

ceiling insulation bath expanded clay

Expanded clay - one of the most effective materials for thermal insulation of the ceiling bath

  1. Basalt fiber. Its advantages include low thermal conductivity, flame resistance and naturalness. The drawback - when wet mineral wool loses all its properties.
  2. Expanded clay. Excellent keeps heat, but pour it should be very thick (30 cm) and its application requires an additional vapor and waterproofing.
  3. Clay with sawdust. The oldest method is the cheapest, but it is very troublesome. Such a layer is required to fill the dry ground to a height of not less than five centimeters.

Important: if as insulation mineral wool ceiling is chosen, then the long-term preservation of its properties it is necessary to arrange a waterproofing film gap for air.

Options insulation of the ceiling in the bath

Go to the next question arising during the construction of baths and saunas - a warm ceiling in the bath.

Since ancient times, people use the baths. Naturally, a large number of variants of warming, both ancient and modern. In this article, we will focus on the most common methods: with the use of modern insulation, and using natural materials.

Thermal insulation of ceilings log baths

Please entire ceiling sheathe executioner's blocksthickness of not less than six centimeters. Next, steam is laid, which is used as a varnish impregnated cardboard or aluminum foil. This layer must be covered with soft clay and only then should start laying the insulation, the thickness of which should be more than 150 mm. As the insulation layer in this method allowed to use:

  • expanded clay;
  • sand;
  • land;
  • clay with sawdust;
  • mineral wool.

I wonder: clay with sawdust prevent the breeding of mice in the roof of the bath.

If the roof is planned for a bath room, the insulation is laid on top of the board. Otherwise, you can do the screed of cement and sand.

Important: special attention should be paid to insulation of the place near the exit pipe.

"Puff" bath ceiling

  • 1 way. On the beam size of 20x20 cm suspended solid ceiling of the grooved planks 25 mm, covered with a double layer of varnish. beams lay on top of the board, between which necessarily must leave gaps. Next, spread out a layer of roofing material, polyethylene, or foil. Next layer - 200 mm of sand or slag.
  • 2 method. The ceiling on beams stitched bottom edging board of 50 mm, which are supported by the steam on the board 50 mm capercaillie. On this board plank ceiling with air gaps better in aspen. The next step - laying a vapor barrier (cardboard), which is smeared with a mixture of clay with sawdust layer of 30 mm. Next fit mineral wool thickness of 150 mm, followed by an airtight film. You can then put attic boards.

Thermal insulation of the ceiling clay baths

And finally, let the old way to the ceiling insulation bath, time-tested, high reliability.

The ceiling is assembled from the dry boards and tonguethickness of at least 40 mm. Educated at laying thick cracks smeared with clay without the addition of sand. After drying the clay solution ceiling covered with a layer of clay, but with sand. Its thickness should be 50-60 mm, and the consistency of clay - for masonry oven. Again, after the complete drying of dry sand is poured to a height of not less than 100 mm.

When the first clay bath soak,soaking wet steam, and then, when the room formed by dry heat, the clay dries quickly and perfectly retains heat, so the temperature in the steam room is preserved for a long time.

Stratified form of ceiling insulation bath

The hole for the pipe outlet should be issued based on the fire safety requirements

Important: with insulation of the ceiling is necessary to properly arrange the pipe outlet. The distance from the ceiling to the boards of the pipe outlet should be at least 250 mm. To comply with fire safety, all edges of the boards adjacent to the hot tube, it is necessary to close a layer of asbestos.

What method of the above would you choose, they are sufficiently effective and reliable.
