lining Preparation of a balcony floor
To properly insulate the floor on the balcony with your own hands, you will first need to prepare it for operation. To do this, remove the old cover, if any.
You should have a concrete concrete slab under your feet. Clean the opened base of dirt. You can do a wet cleaning. After that, wait until the floor on the balcony is completely dry.

In the presence of cracks and places of mowing concrete, bring the floor to the balcony in order. For this it is better to use a puncher or a Bulgarian.
Prepare a solution of epoxy resins or cement in advance and fill it with cavities. It is important to carefully dilate and fill the floor joints with the balcony fencing plates and walls.
Keep in mind that even a small crevice can reduce the insulation in the room.
Therefore do not rely on the skin and carefully close all the problem areas.
When the cement slurry completely dries, use special tools to treat the floor on the balcony. To do this, roll waterproofing.
However, experts recommend applying a special liquid composition that does not allow water to pass through.
At this stage, check the insulation of the plastic windows and the vertical joints of the parapet slabs. All gaps can be filled with foam.
Screed to insulate the balcony floor
To insulate the floor on the balcony with your own hands, a screed is often necessary. Most often it is used with a significant difference in the height of the floor in the room and on the balcony.
This option is suitable for those in whose dwelling at the joints of the walls of the balcony and floor slabs there are serious gaps.

If you need a floor with electric heating, this option is indispensable.
It is important for the screed to choose the right solution. Ready mixes are now sold, allowing you to smooth the floor on the balcony without any problems.
You can also apply a cement-sand mixture. For this, 1 part of the cement is mixed with 3 parts of sand.
It is important to properly prepare the screed composition. This will help to properly insulate the floor on the balcony.
Thoroughly mix it dry, then gradually add water.
At the same time, we follow the consistency: the resulting mixture should be easily poured, but not too liquid.
If you decide to use the finished mixture, then read the instructions. This option is convenient in the presence of experience. Many mixtures instantly freeze, so it is better to hurry with their filling.
If you are not sure about the result, then use a cement-sand mortar - you can not rush with it.
Now fill the floor with the finished mixture.
It will be nice if before that you put a reinforcing wire mesh. The floor is poured on a thickness of 4 cm. We spread the mixture, we correct, using a grater for plaster.
We follow the smoothness through the building level.
When the floors are leveled, we make iron. To do this, fill the filled solution with a light layer of dry cement. Now we have a foundation for the future of the balcony floor.
If you selected heating using a special cable, repeat the filling with the solution by the electrician. Then, boldly lay the floor covering of ceramic granite, tile, stone.
For laying other coatings( linoleum, carpet, laminate), use an infrared heating element - a 0.5 mm thick film.
Material selection and lagging
Now it is necessary to insulate the floor on the balcony. To do this, it is important to choose the right material for thermal insulation. What does the market offer today?
To save money, choose foam. It is waterproof, lightweight, easy to use. They can easily insulate the floor. The only negative is a fire-resistant foam.
Upon ignition, the material leaves toxic fumes.
The next material is extruded polystyrene or foam foam. It is fireproof, durable. With the help of this material it is easy to insulate the room. The material is mechanically reliable.
Therefore, you can insulate the balcony and lag, and screed.
Penofol and other roll materials are not very dense. They allow to warm the room.
Less commonly used mineral wool. It easily fits, but crumples and quickly absorbs moisture. Thus, it will help to insulate the room only for the first time.
Expanded clay is not expensive, but often used for outdoor work. Foamed polyurethane foam in cylinders. Has good performance and at the same high price.
Virtually all of these materials have low density. To properly insulate the floor, it is better to reduce the load on them.
Therefore, for laying the rough floor and the main cover, a log system is used.
Waterproof membrane is placed on a concrete base. For this, dense polyethylene can be used.
We measure the size of the balcony and cut out the beams with a minimum cross-section of 4 × 4 cm according to it. They are processed with an anti-bio-protective compound and laid.
The distance between the beams should be equal to the width of the insulation plate.
Now you need to align the log system along the plane. For this, we place the support wedges under the uneven bars. For greater reliability, we lay small racks between the base and the lags.

When the logs are level, we mount them using self-tapping screws. For maximum rigidity, you can fix the edges of the log to the wall.
For this, we use plate brackets and anchor bolts with plastic sleeves.
If you prefer a roll foil insulation, then fill the lags on top of it. If using a different material, run it between the lags.
Installation of heat insulator, sheathing
The next step is laying the thermal insulation material. For this we use insulation plates for a balcony or loggia. They are cut to the volume of cells located between the lags.
It is best if after this process there are no empty spaces at all.

The resulting materials are placed on the floor or on a layer of roll material. As the fastening of the thermal insulator, it is possible to apply glue-foam in cylinders or plastic dowels with wide hats.
When the panels are laid, the resulting gaps are filled with polyurethane foam. On the heater we place a layer of vapor barrier membrane. Thus, the materials will be protected from moisture.
If the loggia allows, then fix the cross bars on top of the lag. Their cross section can be slightly smaller.
However, the distance between them should not be less than 40 cm.
We proceed to installing the crate with our own hands. Thanks to it, an air layer will be created between the heater and the rough floor. This will improve the thermal insulation qualities.
We begin laying the rough floor on the crate. It can be equipped with plywood, boards or OSB plates. The details are cut to size, we place them on the logs and fix them with screws.
It is best if there is a gap of 10 mm between the boards and the walls of the balcony. This will help the floor last many years and for a long time to insulate it.
The main job is done, it's a small thing - we lay the floor covering, we fix the skirting boards.
If you properly insulate the floor on your own, then not only on the balcony, but in the entire apartment will be provided a comfortable temperature, because very often the balcony door is open.
The bottom layer of air always has a heat loss. To reduce them, it is important to follow the instructions given above.
As you can see, it's not difficult to realize the floor insulation on the balcony with your own hands, it's important to approach this matter responsibly and everything will turn out!
