Heat losses through the roof can reach 30% or more of the total heat losses through the outer shell of the building, therefore, when designing, special attention should be paid to the thermal insulation of the roof.
On top of the thermal insulation a screed is usually installed with a heavy concrete mixture with a thickness of up to 10 cm or more (depending on the size of the roof), both to drain rainwater into special rainwater inlets, and as a basis for a further layers (waterproofing, finishing and other layers in the case of arranging an exploited roof). In addition, plastic containers are installed on the roof to accumulate water up to 2 tons or more, as well as solar collectors and other items used in the operation of the roof. All this creates significant pressure on the thermal insulation layer. When using polymer-based thermal insulation (like polystyrene), the thermal insulation installed under such a weight begins to shrink, losing its thickness. Add to this the extremely high temperatures on the roof in summer, which contribute to the fact that the polymer insulation becomes softer and more susceptible to stress, and the process of compression of the thermal insulation layer becomes even faster and larger. Moreover, unlike laboratory tests, when after the compression of polystyrene by 10% the load is removed from the sample, the polymer insulation installed on the roof will be under such load continuously for the entire life of the building, more and more shrinking (although the process will slow down over time). This process of compressing polymer insulation under load and when heated has two negative consequences. Firstly, a decrease in the actual thickness of the thermal insulation layer leads to a decrease in the thermal resistance of the installed thermal insulation, and therefore to an increase in heating and cooling costs over time. The second negative consequence is that the violation of the geometry of the roofing "pie" leads to peeling and damage to the waterproofing, which in the future can lead to leaks and damage to the interior decoration of the premises on the top floor.
MULTIPOR mineral boards are devoid of these disadvantages. Being a porous stone, they practically do not shrink under load, which, together with the previous point, guarantees a consistently high level of energy efficiency of the roof's thermal protection, and also does not create the prerequisites for violating the integrity of the waterproofing layer. As a result, MULTIPOR allows significant savings in the operation of the building, both for heating / cooling and for repairs.
MULTIPOR is not a cure specifically designed for sound insulation of a building, but it helps to improve the sound insulation of one. It is important for a residential building that the level of external noise is minimal. Road noise is in the low frequency range and is perceived as extremely unpleasant and annoying. MULTIPOR solve this problem thanks to its cellular structure and through the materials used in its composition. Depending on the external wall, its sound insulation index is increased by another 1-2 dB. This makes MULTIPOR one of the best thermal insulation systems in terms of sound insulation and significantly improves the quality of housing, and this means that among other thermal insulation materials
The MULTIPOR external thermal insulation composite system can be installed simply, rapidly, and securely. The MULTIPOR mineral insulation boards are lightweight, can be cut by handsaw, and are free of fibers and toxic substances. Even challenging building geometries such as curves can be simply formed with a MULTIPOR external thermal insulation composite system.
95% of the installation work for MULTIPOR coincides with the application of polystyrene thermal insulation. Construction companies do not need additional time to install MULTIPOR. Moreover, the physical properties of MULTIPOR make it possible to increase the speed of work, including the leveling of facades and the mechanical fastening of MULTIPOR mineral plates, which makes the cost of insulation work with the MULTIPOR system similar to the cost of installing polystyrene insulation.
A complete external thermal insulation system consists of various components. In the MULTIPOR external thermal insulation system, these components are optimally combined with each other and can be used in any building project. The system components are part of the delivery program and are quickly and easily available to you.
