Today, many build bathhouses on their plots. It is clear that it should be as warm as possible. If the owners do not want to receive an inappropriate design, then thinking about every moment is at the planning level. But when creating a full-fledged bath, you can save a lot on firewood.
What to think about? Thermal insulation of the bath ceiling is an important stage in construction. There are enough offers on the market for materials. Before starting construction, it is worth considering any action. After all, each material has its own characteristics and fastening technology.
When is insulation indispensable?
According to experts, do-it-yourself ceiling insulation in baths is not required in every case. There is a law of physics that should not be forgotten: warm air rises. The ceiling restricts the movement of heat, and there it accumulates without benefit. In this situation, it is important what level of thermal conductivity of the ceiling. In the absence of an insulating structure, about 30 percent goes outside.
depending on the season
Some say that for a bath,flooded in the summer, there is nothing wrong with the lack of insulation. If this building is used all year round, then you will have to think about insulation.
Besides this, if a person does not want to drown all day, it is also worth completely eliminating heat loss. This can be done without the involvement of specialists. Since the insulation of the ceiling of the bath is a simple process, it remains only to take the full instruction into service.
Several ways to choose from
As already noted, there are enough ways, you just have to choose your own and implement the project. How is the choice made? This is affected by what is above the ceiling:
- Uninsulated attic.
- Residential attic.
- Flat roof, with little space.
Despite this, there is a limitation in the work. Experts identify several main areas:
- Laying.
- Lined.
- Panel.
As a result, each procedure gives the main result - the insulation of the bath ceiling. With your own hands, this operation can be completed in a couple of days. Before starting, it is worth understanding the effectiveness of each action, the preparation of the material and tools required in the process. Having understood the nuances, you can proceed with the installation.
Deck ceiling
In the process of work, several constituent materials will be required - expanded clay, clay and sawdust. When there is a cold attic, and there is no desire to insulate it, thenit is worth considering some points. The floor version is the most suitable for this design.
This is a simplified erection - since the ceiling is not affected by loads, reinforcement of the beams is not required. The draft design will lie directly on the strapping. By the name of this method, it is clear that an embankment will be produced. Therefore, it is worth laying a chopping block with a thickness of at least 4 centimeters so that collapse does not occur.
What should be the layer?
Materials use any available to the owner of the building. But the principle is the same. This is a "pie" in several layers. Overlay from bottom to top occurs in this way:
- Finish ceiling.
- Layer of vapor barrier material.
- Boards.
- Wax paper.
- Insulation layer.
Vapor barrier
It should be said about the vapor barrier material. Its functions are not only protection against steam, but also the ability to withstand high temperatures. On the market, such a product does not have a large assortment, so it will not be difficult to choose. Many people think foil is the best option.
The warming layer is made of expanded clay, clay with straw. If this is a modern flooring, then so that the constituent elements do not spill through the cracks, paper is used (necessarily waxed). The thickness of the coating reaches 30 centimeters. This is quite enough to ensure that the protection is maximum, and the heat does not go outside. On sale there is expanded clay of various fractions. Importantstack so that no voids form. This is the only way to do the ceiling insulation in the bath with expanded clay.
Some craftsmen additionally stuff boards of small thickness over the surface (for separation.) But there is no great need for this.
Clay and other options
The next type is the use of clay. It is initially soaked, after which it is mixed with straw or sawdust. Insulation of the ceiling in the bath is done when a homogeneous composition is reached. After the resulting mass is distributed around the perimeter of the insulation zone. There is another option: you can dilute the clay, place it over the entire area, let it dry for four days. After the cracks that have appeared, seal them with the same solution. Pour sawdust or oak leaves on the surface, up to 9 centimeters. The final layer is dry clay 5 centimeters.
From the side of the bath (to the draft ceiling) a vapor barrier material is mounted. Joints are sealed with construction tape. After the crate is made, and the ceiling is already installed on it. It can be a forcing or just a chopping block. The choice will depend on the financial capabilities of the owner.
If you compare both of these options, then there is one common minus. This is a lot of weight. This means that the ceiling should be made of thick boards. The advantage of this method is the low cost of raw materials. A good option is to insulate the ceilings in the mineral wool baths with your own hands. Expanded polystyrene is also often used. But such materials will not be cheap.
What should be prepared?
In the process of work, it is worth preparing the necessary raw materials and tools. This is:
- Construction stapler.
- Saw.
- Hammer.
- Boards.
- Foil and wax paper.
- Metal tape.
- Nails.
- Expanded clay or clay.
Before purchasing insulation material, it is worth calculating it so as not to spend too much and perform maximum protection.
Flat ceiling
Creating such a ceiling insulation in baths with a cold roof is not so easy. This is required for those who wish to create a room after the erected structure. If there is a living space on the second floor, then it is worth making the floors reliable and complete. After that, the ceiling is already being filed. Prepare before starting work:
- Construction stapler and tape measure.
- Hammer and saw.
- Sharp knife.
- Male.
- Beams.
- Foil.
- Metal tape.
- Nails with a protective layer.
- Slats for crates.
- Clapboard or other finishing material.
- Insulation.
- Edged board.
- Film for vapor barrier.
Before buying, you should calculate the amount of insulation for the ceiling of the bath. If the bulk method is chosen, then the calculation is made from the height and area of \u200b\u200bthe ceiling. Do not forget about the climatic indicators in the region. What the bottom-up insulation will look like:
- Finishing the ceiling with a top coat.
- Creating a ventilation gap (slats are used for this).
- Vapor barrier overlay.
- Insulation between beams.
- Waterproofing.
- Edged boards.
- Finishing on the ceiling of the attic.
After preparing the necessary materials and the required tools, the work process begins:
- First you need to lay the floor beams.
- After that, the vapor barrier is fixed to them from below. For this, foil is purchased. To completely eliminate the passage of air, it is worth sealing with metal tape. It is good to carry out such work with a stapler.
- So that the steam probably does not gather, the slats are fixed, a gap of 3 centimeters is made.
- For finishing it is better to use lining. But such material is not cheap, so if you wish, you can replace it with something.
- Next is to climb up to the attic. Insulating material and vapor protection are laid between the beams. But what to choose? It is good to insulate the ceiling of the bath with bas alt wool.
- After it is worth laying a layer of waterproofing. If we are talking about a bath, then it is better to give preference to the membrane.
- Further, edged boards are used, everything is hidden under them. Since this part will become the floor for the second floor, concrete should not be used. It's heavy.
- The floor is being laid as a finishing material.
The process is not difficult and anyone can handle it. Do not skip any of the steps, otherwise the design will turn out to be unreliable and will not create additional heat.
How to insulate a panel ceiling?
The masters saysuch a design in the bath is rare, because it is difficult to work with it. The fact is that you need to mount a pallet into which the main materials will be immersed. In the work you will need to apply:
- Hammer.
- Pilou.
- Construction stapler.
- Sharp knife.
- Nails.
- Foil.
- Mineral wool.
- Bars.
- Boards.
To insulate the ceiling of the bath with mineral wool, it is worth taking a thickness of up to 10 centimeters. It is easy to work with the material, as it is cut with a knife, inserted and, if necessary, pressed. You need to mount the pallet depending on the room itself, but the width can be up to half a meter.
Knowing the length and width of the ceiling, you can calculate in advance how much it costs to purchase. There is no need to take extra. Sometimes mineral wool has a high density. In such a situation, it will not work to compress it - only cut it off. But these pieces can be used in some recesses. If the size of the bath ceiling is 3.5 by 3.5 meters, then 22 standard mats will suffice.
It is clear that in the bath the temperature rises strongly, so it will not work to use any insulation. Particular attention is paid to the place where a person will bathe. Material must be:
- Combustible. Do not create smoke in case of fire.
- Able to resist temperatures up to 100 degrees.
- Do not take liquid.
- Do not release chemicals into the air.
Find completequality and suitable material is not easy, because each has its own pros and cons. Therefore, it is worth building your choice based on these data. How the work is going:
- The new design is made first. This requires bars or boards, the length of which can reach up to half a meter.
- The bars are fixed at a distance of half a meter, and the boards are fixed perpendicularly to the fasteners. An indent of 4 centimeters is made from the edge.
- According to external data, this is a box. The vapor barrier is deepened into it. Then it is fixed. Such a shield must be raised up. It is better to strengthen it so that it does not fall apart.
- The created shields are placed close together on the roof.
- The walls will be the supports for such a structure. From this it follows that their length should be identical. The insulation is laid in the existing pockets. Next, the overlay of the flooring boards is done and after that - the finishing floor.
Panel ceiling is used in baths with two floors. It is compared with a hemmed one. As a result, everyone decides for himself whether to save or not on the construction of the structure. When working with the installation of a panel ceiling, you should not use plastic in the finish. He is very afraid of high temperatures. So, a few hours after using the bath, this whole structure can simply be deformed, ruining the entire interior of the room.
Conclusion
So, we figured out how to insulate the bath on our own. Before making the final choice of material, it is worth familiarizing yourself with the characteristics of each insulation. It will only be soclear which is better. Some have increased flammability, which is definitely unacceptable. Builders believe that ceiling insulation should be planned at the level of bath construction. And everyone can do it with their own hands, without involving specialists.
