Flat roof insulation with MULTIPOR
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.
The advantages of the MULTIPOR system
In summer, the roofs of Cypriot houses warm up to extremely high temperatures - up to 60C and above, so thermal insulation must be immune to such conditions.
In addition, a heavy screed with a slope is usually made on top of the thermal insulation to remove rainwater, as well as various heavy equipment is installed. To maintain the integrity of the waterproofing layer and protect the house from leaks, it is also important that the thermal insulation does not shrink under loads on the roof.
Finally, an effective solution is needed to remove possible water underneath the waterproofing layer.
MULTIPOR successfully copes with all these tasks.

MULTIPOR is a system for those who are building a House for themselves and their families!
Thanks to its composition (MULTIPOR is made of sand, cement and lime, with no synthetic materials) MULTIPOR meets these and other strong requirements to the greatest extent, making it the most effective and long-lasting solution for thermal insulation of flat roofs of buildings in the hot and humid climate of Cyprus.
Unlike the currently most used polystyrenes, MULTIPOR does not lose its thermal resistance over time and does not accumulate moisture under it, which ultimately guarantees a consistently high level of thermal insulation for roofs insulated with MULTIPOR for decades. In addition, MULTIPOR provides its owner with the maximum life span of thermal insulation and significantly reduces the owner’s building maintenance costs compared to other insulation materials in Cyprus. This makes MULTIPOR the most economical solution for those who intend to live in houses insulated with MULTIPOR for a long time.

THE MAIN REASONS TO CHOOSE MULTIPOR FOR EXTERNAL INSULATION OF THE ROOF OF YOUR HOME:
Consistently high thermal efficiency
Unlike other common thermal insulation materials, MULTIPOR is the completely mineral-based material made of sand, cement and lime. These raw materials are not affected to ultraviolet, high temperatures or rainwater. Therefore, the life time of MULTIPOR mineral boards in Cyprus is times longer compared to other insulating materials. In addition, MULTIPOR has stable, irreducible thermal efficiency (thermal conductivity), geometry and compressive strength throughout the life of your building, which are the weak points of other insulation materials at high temperatures in Cyprus.
Moreover, these bills mentioned above will be lower even in comparison with houses insulated with seemingly "warmer" polystyrene, since in houses insulated with MULTIPOR there is no need to keep windows and doors opened constantly to remove excess moisture.
Important fact that unlike most countries in Europe and the UK, Cyprus' climate is hot and humid, with a large difference in daytime and nighttime temperatures in summer. This creates uncomfortable conditions for building materials with synthetic base, such as styrene in polystyrene or resin in insulation wools. Even been protected from harsh UV radiation with reinforcement layer, these materials are exposed to high temperatures. When there are only 2−3 weeks with a temperature on the facades about 40 Celsius in the most EU countries with a moderate climate, in Cyprus our facades can be heated up to above 50 Celsius for several months.
Such extreme temperature conditions drastically shorten the life span of synthetic-based building materials, including polystyrene and insulation wool. Polystyrene loses its thermal properties due to the "thermal drift" effect (when a special gas inside the polystyrene is replaced by ordinary air due to the diffusion effect, which occurs the faster, the higher the temperature on facades) and due to thermal destruction (the most of polystyrenes has 60−70 Celsius maximum operating temperature for long time using and the closer temperature of facades to this range the faster polystyrene destruction). Most of the resins used in mineral wool do not have a long service life when heated, which also leads to their rather rapid degradation in the climatic conditions of Cyprus. Therefore MULTIPOR is the strongest and most durable thermal insulation in Cyprus.
Consistently low thermal conductivity of MULTIPOR, for decades, grants homeowners with consistently low cooling / heating bills over the life of the building, as well as no significant cost to replace aged thermal insulation every 10−12 years in hot climate of Cyprus.

Stable geometry of the MULTIPOR thermal insulation layer
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.

The highest fire safety rating
Made of mineral raw materials, MULTIPOR does not contain any flammable or combustible materials at all. When put into fire, MULTIPOR can withstand fire for up to 12 hours or more, which is much more than other insulating materials (especially in comparison with polystyrene). Thanks to MULTIPOR, in the event of a fire, no flammable droplets are formed, which prevents the fast spread of fire along facades during a fire. In addition, MULTIPOR does not produce fatal fire smoke, which is the leading cause of deaths when fire. Unlike other insulating materials, MULTIPOR can be easily repaired without the complete replacement even after a fire, which is another economically valuable feature of MULTIPOR.
The best fire safety properties makes MULTIPOR the most desired thermal insulation material for both private and apartment buildings, when safety is a priority!

Built-in sound insulation
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
MULTIPOR is an effective sound insulation against traffic noise and similar noises
Reducing investment and operating costs for engineering systems
A properly insulated home requires less energy to cool or heat. Given the rather warm climate of Cyprus, it is possible to abandon expensive floor heating systems and replace expensive powerful air conditioning systems with cheaper ones with less energy consumption. Complex and powerful electromechanical machines require annual service, external power supplies and must be replaced with new ones every 10−15 years, whereas MULTIPOR is paid for and installed only during construction or renovation work, without any future costs for service work or energy sources (electricity, fuel, etc.). Therefore,
MULTIPOR helps to reduce costs both for investment in complex and expensive heating and cooling systems and for maintenance, power supply and replacement of this equipment in the future.
