In a proper store renovation, the floor must be designed and constructed in such a way that during support construction, it permanently provides the following demanding but standard specifications:
Stability, surface smoothness and safety – loads provided by the design must be transmitted from the floor to the support structure without damage or permanent deformation. Acoustic Protection – According to SRPS U.J6.201, the ceiling between two levels must meet the requirements for the lowest value of Rw of 52dB sound insulation and the highest value of the Lw of 68dB sound level.
Thermal protection – in accordance with the technical conditions for thermal protection of buildings, such as SRPS U.J5.600 Fire protection – fire protection regulations are clear: in the event of fire, or during floor decomposition, toxic gases, which are poisonous, should not be released, which increases the risk of inhalation by rescuers and trapped and makes rescue difficult. All this is achieved simultaneously with the use of Knauf Rock mineral wool insulation.
Floor insulation The use of mineral wool provides the following advantages: High level of protection against impact sounds – such floors belong to the class of improved acoustic protection according to the existing Standard. Reduced transmission of air sounds through structures – an extremely absorbent material Thermal protection – heat conduction band Increased fire protection of the building – is non-combustible material with extremely high melting temperature above 1000˚C
Excellent adaptability to possibly uneven areas of the base – the plates are flexible with fixed shapes No sound and thermal bridges are likely to occur – good adhesion at the edges of the plates reduces the chance of distances between the plates Great installation delivery – simple and fast installation Possibility of flooring above installation pipes – installation pipes can be guided through the insulating layer A ringing sound is the sound that is produced when one vibrating object hits another, and is transmitted through a solid medium.These sounds are found on the floors of buildings as they are produced by walking, chair sliding, the operation of household appliances that are in contact with the floor, etc. A common annoyance and a very common cause of complaints by tenants. Sound insulation is now required to create sound insulation.
A natural feature of the ceiling that indicates the permeability for sound energy is called the level of smoothing of the beating sound, and the unit of measure is (dB).The main insulating solution for the buzzing sounds in modern civil engineering is floating floors.———Installation of floating floors For the installation of a floating floor structure, the structure must be dry and flat:
Side Knauf Rock d = 1cm mineral wool dividers on perimeter walls are intended to separate construction from walls and to prevent sound bridges from appearing. total height of the floor The stone wool insulation plates are located exactly next to each other. The wool used will depend on the purpose of the floor and the expected load: “wet” method “dry” methodPOD CLASSIC ≤ 2.0kN / m2POD PLUS ≤ 5.0kN / m2POD EXTRA ≤ 10.0kN / m2POD PE or PVC film with a coating of 10 – 15 cm, which should be glued with a simple wide insulating tape.
This film is intended to protect the insulating liner from moisture created during the construction of the liquid floor smoothing mortar or when the floor is under unheated space. The film bends in a vertical position from horizontal, in front of the wall, just above the edges of the partitions Rigid plate – here are two ways based on the material: – wet method: screeded bed is achieved by applying concrete on the ground – to a thickness not less than 4 cm (note: thickness depends on the load and degree of compression of the insulation surface – you should consult the mortar manufacturer). Such mortar should definitely be reinforced with a reinforcing grid made of suitable fibers.
