Importance of floor insulation
Insulating the floors provides protection against the cold and reduces heat losses. For this, mineral wool or Styrofoam is used, the upper side of which is protected by a cement lining. A floor covering, parquet or pathos is placed on the cement screed. Waterproofing is placed between the mineral wool and the concrete slab. A good craftsman will know exactly what kind of floor insulation is best to install, so we recommend that you post the required service on Bellcom.rs and wait for offers from companies in your area.
Methods for floor insulation
Floor insulation When it comes to methods of insulating floors, the most expedient method to keep the cold from below from leaking through the foundation and into the house is to install high pressure resistant thermal insulation directly under the foundation slab. Using this method, the thermal insulation effect is so good that even low ground temperatures, significantly lower than 10 °C, are not felt at all from the inside of the floor slab. A protective dam against the cold should ideally consist of thermal insulation boards simultaneously resistant to high pressure loads – strength class 50 or 70. These thermal insulation boards are therefore so strong that the entire building can be placed on them.
Insulation of floors with stone wool
When it comes to insulating floors with stone wool, thermal and sound insulation is provided in this way. The installation itself is done in two ways, depending on whether it is a floor on the ground or a mezzanine floor. Floating floor is the most common name for this installation system, and in addition to the basic installation, attention should be paid to stacking stone wool skirting boards along the walls, which prevent noise from being transmitted through the walls to neighboring or to the rooms below, in addition to the floor. In our country, Styrodur (pressed Styrofoam), which has a higher density than Styrofoam, is used a lot for this purpose. The difference between the two materials is quite large and no simple answer can be given as to which is better. It is highly recommended that the master who installs the floating floor has previous experience with the material we have decided on (styrofoam or stone wool).
The importance of attic floor insulation
If the attic is not used as a residential or business space, that is, if people do not stay in it for a long period of time during a day or night, it is logical that such a space is not heated using any of the energy sources (electricity, coal, gas, wood. However, it is all the more important to thermally insulate the last mezzanine panel by installing thermal insulation in the attic floor, so that energy (heat) flows from the heated floor below the attic to the unheated attic as little as possible, and then through the attic and out of the building.
How to ensure quality floor insulation?
To ensure high-quality floor insulation, a floating floor with stone wool 5 cm thick is used. It is necessary to place a vapor-permeable foil on the upper and lower sides, since it is placed towards the heated side. By the way, the building standards stipulate that this must be done, because in this way the sound insulation of the floor is increased, which contributes to better living conditions. Thermal insulation of cold floors is a simple way to reduce heat losses and improve living comfort. If there is no adequate thermal insulation in the case of underfloor heating, large heat losses occur. In new buildings, the losses amount to about 6% of the total heat losses, but even then the installation of insulation is recommended. In this case, the thermal insulation of the basement ceiling is particularly effective. The thickness of the floor insulation depends on the temperature of the cold room, and it should be 8 cm for floors above heated rooms and 10 cm for floors facing the outside air. If there is a floor heating system, these dimensions should be increased by 3 cm. sr
