The key difference in this category of repair solutions is the elimination of a rigid connection of the floor with the base. The design looks like a multi-layered “pie”, in which materials with different performance characteristics and capabilities are combined. To identify the advantages and disadvantages of the floating floor, it is necessary to consider the conditions of its use and features of the device.
Advantages of innovative technology
The generally accepted concrete screed is in many respects inferior to floating floors, primarily in sound-proofing properties. This property is achieved precisely due to the independent position of the coating relative to the walls and the foundation. It should also be noted high-quality insulation, especially valuable for those who live on the first floor. Another advantage is the relative ease of installation procedures: the device of the floating floor is not accompanied by difficulties, even if prefabricated variations are chosen or a dry screed is used.
One of the reasons for the concern of the tenants of apartment buildings is the variety of percussion noises that appear when moving heavy objects, children's games, and fast walking. Concrete floors almost do not absorb them, but the floating floor on the logs can 50% increase the noise insulation of the dwelling. It is important that the design does not need special care, it, like analogs, can be vacuumed, washed.
Key floor types
Cork, dry, prefabricated and concrete construction options are common, then each of them will be considered.
When at the heart of traffic jam
Floating cork floors are made of laminated panels, while on top is a natural material. The panels are characterized by a unique pattern, they are not fixed on the base, but connected to each other with grooves and ridges (the joints are fixed with moisture-resistant glue). If necessary, the structure can be dismantled and assembled without losses on another site.
Installation of floating floors involves the formation of 3 key layers. First of all, the base is settled: it can be a reinforced concrete floor, a solid wooden floor or a traditional concrete screed.
Works start with the alignment of the base. If laying floating floors involves using a tongue-and-groove board or laminate, there is no need for a concrete screed. Acceptable if the base does not have significant differences, so you can even use the old coating.
When the surface of an existing carpet or linoleum is perfectly flat, you can create a floating floor from a cork on them - you just need to remove the baseboard. If a concrete screed is used, it must be clean and completely dry, it is covered with a thin substrate (the strips are laid at a distance of 1-2 cm). Since the cork is a hygroscopic material, an isolon layer will be needed here, a polyethylene or vapor barrier film is permissible. It is cut off with an overlap on the wall, which should be at least 6-12 cm.
The most popular method of leveling, as it is easy to install and relatively low cost. It is also important that he does not need time to dry, you can quickly go to the final stage of work.
Compared with a concrete screed, dry is lightweight, so it does not become a factor in increasing the load on the supporting structures. Its main disadvantage is low moisture resistance, but this can be corrected through the introduction of innovative waterproofing materials.
As a rule, two layers form a dry screed: bulk material and sheet components covering it. In the form of backfill often used claydite, quartz, silica, perlite sand. This procedure perfectly aligns the floor, forms a complete heat and sound insulation.
The technology of work is such that as a result, a strong, durable coating is formed that is not afraid of temperature differences and has excellent heat and sound insulating characteristics. If the installation is carried out on the first floors, the first step will be to create a waterproofing layer on a dry fill, mineral wool, polystyrene foam, polystyrene foam. Further, the perimeter is covered with a contour tape, which is necessary to protect the walls during operation.
In order to create a floating floor as a result of a complex of installation works, resistant to external influences and high operational load, experts recommend that you follow several rules:
- the structure does not need additional fixation to the base with nails or screws;
- the direction of work should be perpendicular to the windows, be sure to leave gaps near the walls;
- installation is carried out in a dry room with the usual room temperature;
- when a prefabricated floor is formed, it is advisable to leave unopened packages with panels in the room for which they are intended for 2-3 days.
To take full advantage of the advantages of floating floors, you should wait a little with the introduction of baseboards - they are set after some time, the exact dates depend on the selected type of finish.
