Many advise making the insulation of the balcony with foam blocks. But this is a very expensive method, and should be resorted to only in cases where other options are unacceptable. Where should we start the arrangement of a new room? Of course, with the installation of windows.
In order not to bore you with long explanations, in short we can say that the best choice for today is the PVC profile with a double-glazed double-glazed window. After installing the windows, it is necessary to seal all the cracks left between the floor and the walls with a sealant.
Then the remaining cavities should be filled with a mounting foam. Unfortunately, in most high-rise buildings, there is not always an opportunity to make the balcony insulation from the outside. And so many apartment owners isolate them only from the inside.
Thermal insulation of balcony - instructions for laying insulation
But if you conduct internal insulation without following certain rules, this may lead to the appearance of puddles in the winter under the windows of the balcony on the floor. The fact is that without proper thermal insulation inside the insulation will begin to accumulate condensate, and this in turn leads to a significant reduction in its heat-saving properties.
To prevent this from happening, anyone who does the balcony insulation, instruction advises to install a vapor barrier before the insulation layer. With this function, ordinary polyethylene film or aluminum foil will successfully cope. The only drawback of this method is the lack of air permeability in the structure. In other words, the wall simply stops "breathing".
In order to prevent the accumulation of moisture, you can also make the insulation of the balcony with expanded polystyrene. It is a material that has excellent heat-insulating qualities, high strength and low hygroscopicity.
Thermal insulation of the balcony by polystyrene with its own hands will increase the service life of insulation up to 40 years. This material is considered to be the most popular and simple enough to use today, but, unfortunately, it is suitable only for minimal insulation due to its insufficiently high thermal insulation properties.
Thermal insulation of the balcony with foam - we finish the operation with a competent finish
After installation of the insulation material, the second layer of polyethylene is laid, which later serves not only as a vapor barrier, but also as an additional insulation. It should be remembered that the effectiveness of the vapor barrier is directly related to the quality of the work.
When the insulation is ready you can start the finish. To do this, 2-3 pine logs with a section of 5 cm are installed on the layer of insulating material. The distance between them should be within half a meter. Subsequently, they are nailed on boards with a thickness of 30 to 50 mm.
The walls are best finished with wooden lining. Also good suited and gypsum cardboard, which can be painted or wallpapered with wallpaper. Some owners use PVC panels for this purpose. For the installation of the battens, dowels and screws are used to fix it on a concrete wall. Do not forget at the same time to check the construction level of the position of the beams.
If you plan to put electrical wiring on the balcony, you should take care of it in advance and prepare the relevant materials for work. All the wires must be carefully laid under the finishing lining. On this, the process of warming can be considered complete, and for greater clarity of how the balcony is self-insulated, the video is at the end of this article and is ready to answer the remaining questions.
