The loggia is often used as an additional area, allowing, although not by much, but still expand, and legally. Most likely, she will want to use it in the winter.
The need to install modern double-glazed windows on the balcony is no doubt. And if it is better to entrust it to specialists, then floor insulation on the loggia can be done by yourself.
But first you need to decide on the finish coating, because the choice of construction technology is directly related to it: for linoleum or floor tiles you will need a cement screed, for a laminate or a treated floorboard , it is possible to insulate the loggia floor on rough floors.
Whichever option is chosen, first remove the old coatings carefully, carefully inspect the base plate. It should be tapped, and if holes and gaps, obvious voids are found in it, they are cleaned and sealed with a solution.
Large enough defects are recommended to be fixed with additional fittings. To do this, a grinder previously saws transverse incisions, not very deep, and lay metal fittings there. The holes are then poured with a solution. Any iron scraps that fit in the recesses will do.
Floors with skews and significant irregularities are leveled with a preliminary screed. After they have completely dried, they are primed to avoid the formation of mold and dampness.
Insulation of the floor on the loggia can be performed with a variety of materials: expanded clay, polystyrene, glass wool, but the best insulation for the balcony is extruded polystyrene foam. It can be cut to any size, and the material does not crumble. Extruded polystyrene foam has excellent insulation qualities, and under the influence of temperatures it practically does not change its size. For this reason, it is not subject to destruction and, accordingly, has a long service life.
It is lightweight, but it can withstand high loads. In addition, it is water and fire resistant, and this is not all of its virtues. Of course, and it costs slightly higher than, say, traditional polystyrene foam.
You can choose any insulation, but in order to keep it tight and well and not move, formwork (logs) is performed. The structure is closed on top with a hard coating, since the screed does not fit on loose and soft materials. Expanded polystyrene in this case is distinguished by its properties - for it a similar design is not needed, as are hydro- and vapor barrier, because this material does not absorb moisture at all.
Insulation of the floor on the loggia using extruded polystyrene foam gives excellent results, and this method is quite simple. Special glue is applied to the stove and floor surface (it should be diluted strictly according to the instructions). The mass is applied around the perimeter of the sheet using a notched trowel.
Styrofoam sheets can also be fastened with dowels in the form of a mushroom. Plastic dowels with a specially enlarged hat and nails secure the whole plate in the corners and in the middle. Some use both methods for efficiency at the same time.
The sheets cut by an ordinary hacksaw are fixed in a checkerboard pattern. To seal the joints, foam is used, which should not contain toluene - it destroys the extruded polystyrene foam.
Additional insulation of the floor on the loggia creates a foamed foil polyethylene laid on top of it , with a layer of 3-10 mm. They fasten it end-to-end with glue and glue the seams with foil tape.
Thus, the result is a room reminiscent of a thermos inside, completely isolated from the cold on the street.
