Warming of the balcony with foam plastic: step by step instructions. How to make a warm balcony

Balconies and loggias have recently been made part of a living room. However, if you want to do just a little warmer this room, then the appropriate work should be done. Warming the balcony with foam plastic is a rather laborious process, so it is recommended that you familiarize yourself first with the technology of the work. In the market of modern building materials there are many solutions that could be suitable for this. However, one of the most popular and inexpensive is polystyrene foam. Therefore, it has become so widespread.

Why choose a foam

The popularity of polystyrene is also determined by the ease of its installation, as well as by its light weight. This material has excellent insulation properties and exhibits excellent resistance to aggressive media. The temperature of its operation varies in a fairly wide range and can be from -180 to +80 ° C. If you want to trim the balcony with polystyrene foam, you can be sure that it will show resistance to biological effects. On its surface, the fungus and mold will not appear during the entire service life.

Preparation of tools and materials

Thermal insulation of the balcony with foam makes it possible to eliminate the need for additional vapor barrier, because the described thermal insulation provides high steam throughput. The material practically does not pass water, therefore it has also waterproofing properties.

Before starting the insulation work, the following materials and tools should be prepared:

• Wooden slats;
• Dowels with hats;
• Mounting foam;
• Self-tapping screws;
• Sheets of waterproofing or roofing material.

It is important before going to the store to determine how much material is required for warming. Do not buy the cheapest insulation, because in this case its quality will not be the highest.

Preparatory work

If you decide to trim the balcony, then first you need to prepare. It is important to remove all old things, prepare the walls and floor, and also dismantle the old balcony frames. If the house has tiled finish, then it is better to remove it within the balcony. The rails and partitions can be left - they will act as additional heat insulation. At the final stage, it is possible to coat the surface with plastic or other finishing material.

Leveling and thermal insulation of the floor

If you carry out the warming of the balcony with your own hands, step by step instruction will help in this. It is important to know before starting work that almost a quarter of the heat is lost through the floor. Therefore, it is best to begin the insulation with this part. To do this, remove old coatings, you should also check the base plate. It can have cracks, voids and holes, which are sealed with a solution.

Warming the balcony with foam plastic requires the application of a primer on the surface of the floor, which will help to avoid the formation of mold and dampness. As a material for insulation can be used polystyrene, on the surface of which is laid finishing, usually a ceramic tile.

Additional recommendations for floor insulation

Quite often, in recent years, domestic masters are warming the balcony with their own hands. Step-by-step instruction, presented in the article, will help you in this. For the floor it is best to use 5 cm slabs of PPT-25 grade. The number indicates the density of the material. If you choose a heater with a less impressive density, it can not be used to carry out the described work.

Before laying foam on the floor, a layer of waterproofing is applied, which can be a normal film. Plates of styrofoam should be cut to size and laid as tightly as possible on the surface of the oilcloth. From above everything can be poured with a cement-sand mixture, the thickness of which is about 5 cm. You can apply self-leveling compounds, however, they are more expensive.

Once the screed has dried, the work on the insulation of the balcony can be continued. On a concrete foundation, the wooden crate is strengthened and leveled with the help of a building level. For fastening it is recommended to use roofing screws with a bolt head. Slots along the perimeter are filled with mounting foam where the lath adjoins the walls.

Between the cross rails should be placed thermal insulation. Between the heater and the construction there should be no gaps. If this can not be avoided, the slots should be filled with a mounting foam. It is recommended to use a gun, and the jet of foam should be minimal.

Methods of work

If you are thinking about how to make a warm balcony, then the next step with a construction stapler and 10 mm staples is to fix the cotton wool along the fence, then there is a polyethylene film that will eliminate the wetting of the previous layer. The final stage will be laying the board or plywood, you can put any material on top. As it can make:

• laminate;
• linoleum;
• Euro-admission;
• Carpet.

Use this method of thermal insulation can only be in the area where not very severe winters. As a minus of this technology is the fact that on the surface of the plate are laid bars, which have a greater thermal conductivity than in thermal insulation. As a result, islands of heat loss appear.

Wall warming

If you use foam to insulate the balcony from the inside, then the next step is to proceed with the thermal insulation of the walls. For finishing, PVC panels are usually used in this case. Foam is fixed to the walls with cement glue. It is applied to the insulation by a thin layer, as well as to the ends of the sheet, where the webs will be pressed against each other and against the wall.

In order to ensure a more reliable fastening, each sheet should be additionally fixed with dowel-nails, which have wide hats, called fungi. To do this, using a drill with a winning tip, you need to make holes, and then install the dowel and hammer a nail. The dowel cap must be slightly recessed into the material.

Once the insulation is strengthened, it should be installed with liquid nails penofol, it will act as an additional layer of thermal insulation. In order to achieve a better result, it is recommended to use whole pieces. Seams between the material must be sealed with foil tape.

The technology of thermal insulation of the balcony with foam plastic in the wall area at the next stage requires the fixation of wooden rails with the subsequent fixing of the finishing material. The thickness of the slats can vary from 3 to 5 cm, this will save the useful area.

Reiki should be reinforced with metal corners, which are fixed with dowel-nails and self-tapping screws. To the bar, one end of the corner should be reinforced using a screw, while the other end must be fixed with a dowel-nail to the wall. The distance between the slats can vary from 35 to 40 cm.

Reviews about the thermal insulation of the balcony with polystyrene foam

After reading the reviews on the insulation of the balcony with polystyrene foam, you will be able to find out what some house masters believe: the crate of the bars should be reinforced at first, and then between the elements it is necessary to have a heater. This method is not suitable for the walls of the balcony, according to experts. In this case, you risk creating a lot of islands on the surface of heat loss, because wood has a greater heat transfer than a heater.

According to some home masters, you can use paint as a finishing finish. In this case, there is an opportunity to save space and money, because you do not have to install a crate. Once the polystyrene has been glued, the dowel caps must be covered with putty or glue, with which the material was installed. After the layer has dried, the foam base should be glued with a reinforced mesh. As soon as the surface dries, another layer of adhesive should be applied and leveled with a spatula. At the final stage, applying putty, and after - priming and paint.

Parapet insulation

Polyfoam - insulation, which can be used for thermal insulation of any part of the balcony, including the parapet. However, the technology in this case will have some features. If there are slots on the parapet between the sheathing of concrete slabs, they should be filled with a mounting foam. Since the parapet is located between the balcony and the street, it is exposed to temperature loads. This indicates that the maximum insulation thickness should be used for thermal insulation.

Sometimes the parapet has a metal construction. In this case, it is possible to apply foam blocks of small thickness, on top of which the plates of foam are pasted. If you decide to lay the sheets of thermal insulation to the metal parapet, then two layers should be used. Warming of the balcony with foam plastic at the same time provides for the installation of a crate.

Open the slabs in such a way that there is space between the bar and the foam sheet within 1 cm. Next, the sheet is put in place and in a circle filled with mounting foam. After you can go to the installation of the second crate. It is necessary to do this in such a way that the bars of the first are not connected to the second bar. The mounting foam is applied in a zigzag pattern, and on the glued sheet of foam it is necessary to install one more sheet, filling the resulting cracks with foam.

Conclusion

Polyfoam - insulation, which is also suitable for thermal insulation of the main wall. Quite often these works are not carried out, because they are able to take a useful area of 50 mm or more. If you still decided to insulate the main wall, then you need to act by analogy with the balcony walls.
