Balconies and loggias recently madepart of a living room. However, if you want to make only a little warmer this room, then you should carry out the relevant work. Warming of the balcony with foam plastic is quite a laborious process, so it is recommended to get acquainted with the technology of the work. On 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 foam. Therefore, he was so widespread.
Why choose foam
The popularity of foam is also due toease of installation, as well as low weight. This material has excellent insulating characteristics and shows excellent resistance to aggressive environmental influences. The temperature of its operation varies in a fairly wide range and can range from -180 to +80 ° C. If you want to sheathe a balcony with foam, you can be sure that it will be resistant to biological effects. On its surface during the entire period of operation does not appear fungus and mold.
Preparation of tools and materials
Warming of a balcony with polyfoam allows to excludethe need to use an additional vapor barrier, because the described insulation provides high vapor permeability. The material practically does not pass water, therefore, it also has waterproofing properties.
Before starting work on insulation, the following materials and tools should be prepared:
- wooden slats;
- cap dowels;
- foam;
- self-tapping screws;
- sheets of waterproofing or ruberoid.
It is important to determine before going to the store whichthe amount of material required for insulation. You should not buy the cheapest insulation, because in this case its quality will not be the highest.
Preparatory work
If you decide to sheathe the balcony, then for startersneed to carry out training. It is important to remove all old things, prepare the walls and floor, and also dismantle the old balcony frames. If the house has a tiled finish, it is better to remove it within the balcony. Railings and partitions can be left - they will serve as additional thermal insulation. At the final stage, you can sheathe the surface with plastic or other finishing material.
Leveling and floor insulation
If you will carry out the insulation of your balconyhands, step by step instructions 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 start thermal insulation from this part. To do this, remove the old coating, you should check the base plate. There may be gaps, voids and holes that are sealed with mortar.
Warming of the balcony with foam plastic suggeststhe need to apply a primer on the floor surface, which will help avoid the formation of mold and dampness. As a material for insulation, you can use foam, on the surface of which a fine finish is laid, usually it is a ceramic tile.
Additional recommendations for floor insulation
Quite often lately homecraftsmen carry out the insulation of the balcony with their own hands. Step-by-step instructions presented in the article will help you with this. For the floor is best to use a 5-cm plate brand PPT-25. The figure indicates the density of the material. If you choose a heater with a less impressive density, then it cannot be used to carry out the described works.
Before laying the foam layer on the floor is coveredwaterproofing, which can act as a regular film. Plates of foam should be cut to size and lay as tightly as possible on the surface of oilcloth. On top of everything, you can pour a cement-sand mixture, the thickness of which will be approximately 5 cm. Self-leveling compounds can also be used, but they are more expensive.
As soon as the screed is dry, weatherization workthe balcony can be continued. The wooden crate is reinforced on the concrete base and leveled with the help of a building level. For fasteners it is recommended to use roofing screws with a bolt head. The gaps along the perimeter are filled with mounting foam where the crate is adjacent to the walls.
Between the transverse bars should be placedthermal insulation. There should be no gaps between insulation and construction. If this was not avoided, the gap should be filled with foam. It is recommended to use a gun, and the foam jet should be minimal.
Methods of work
If you pondered the question of howto make a warm balcony, then at the next stage with the help of a construction stapler and 10 mm staples it is necessary to fix the wool over the batten, then there is a plastic film that will prevent the previous layer from getting wet. The final step will be laying the board or plywood, you can put any material on top. As it can act:
- laminate;
- linoleum;
- eurodosk;
- carpet
You can use this method of insulationonly in the area where winters are not very harsh. The disadvantage of this technology is the fact that bars that have a higher thermal conductivity compared to thermal insulation are placed on the surface of the slab. As a result, there are islands of heat loss.
Wall insulation
If you use foam forinsulation of the balcony from the inside, then in the next stage should proceed to the insulation of the walls. In this case, PVC panels are commonly used for finishing. The foam is attached to the walls with cement glue. It is applied to the insulation with a thin layer, as well as on the ends of the sheet, where the canvases will be pressed against each other and against the wall.
Для того чтобы обеспечить более надежное fixing, each sheet should additionally fix the dowel-nails, which have wide caps, called fungi. To do this, using a drill with a pointed tip, you need to make holes, and then install the dowel and hammer a nail. The dowel cap should be slightly recessed into the material.
Как только утеплитель будет укреплен, на нем should be using liquid nails install penofol, he will make an additional layer of insulation. In order to achieve a better result, it is recommended to use whole pieces. The seams between the material must be sealed with foil tape.
Balcony insulation technology with foam plasticthe area of the walls in the next step involves the need for fixing wooden slats, followed by fixing the finishing material. The thickness of the rails can vary from 3 to 5 cm, this will save a usable area.
Reiki should be strengthened withmetal corners, which are fixed by dowel-nails and screws. To the bar should be strengthened one end of the corner, using a screw, while the other end should be fixed dowel-nail to the wall. The distance between the slats can vary from 35 to 40 cm.
Reviews of thermal insulation of the balcony foam
After reading reviews about the insulation of the balcony with foam plastic,You will be able to learn that some home masters believe that the crate of the bars should be strengthened at the beginning, and then a heater should be placed between its elements. This method is not suitable for balcony walls, as experts believe. In this case, you risk forming a large number of islands of heat loss on the surface, because wood has a greater heat transfer compared with insulation.
According to some home craftsmen,paint can be used as a finish. In this case, it is possible to save space and money, because you will not have to install the crate. As soon as the foam will be glued, the caps of the dowels must be covered with a putty or glue with which the material was installed. After the layer dries, the base of the foam should be glued with a reinforced mesh. As soon as the surface is dry, apply another layer of adhesive and smooth it with a spatula. At the final stage, putty is applied, and after - primer and paint.
Parapet insulation
Polyfoam - insulation that canuse for the insulation of any part of the balcony, including the parapet. However, the technology in this case will have some features. If there are gaps in the parapet between the lining of concrete slabs, they should be filled with foam. Since the parapet is located between the balcony and the street, it is subjected to temperature loads. This indicates that the insulation should be used as thick as possible insulation.
Иногда парапет имеет металлическую конструкцию.In this case, you can use the foam blocks of small thickness, on top of which are glued foam plate. If you decide to put sheets of insulation to the metal parapet, then you should use two layers. Thermal insulation of the balcony with foam in this case requires the installation of crates.
It is necessary to cut the plates in such a way thatBetween the bar and the sheet of foam remained a space within 1 cm. Next, the sheet is installed in place and in a circle filled with mounting foam. Then you can proceed to the installation of the second obreshetki. This must be done in such a way that the bars of the first are not connected to the bars of the second. The mounting foam is applied in a zigzag manner, and on the glued sheet of foam plastic it is necessary to install another sheet, filling the cracks with foam.
Conclusion
Polyfoam - a heater which perfectly will approachalso for thermal insulation of the main wall. Quite often, these works are not carried out, because they are able to pick up a useful area of 50 mm or more. If you nevertheless decide to insulate the capital wall, then it is necessary to act by analogy with balcony walls.
