Pitched 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 thermal insulation system

There are two special requirements for thermal insulation material for use in pitched roof thermal insulation in Cyprus.
The first is the ability to maintain its thermal insulation properties even at ultra-high roof temperatures typical for the Cyprus climate. The second is to have a high water vapor permeability in order to ensure a dry state of both the insulation itself and the wooden structures under it.
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.

Consistently high thermal efficiency even in hot countries

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.

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.

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 and the temperature on the roof can rise up to 60 degrees, which is the limit value for most polystyrene used for thermal insulation.
Such extreme temperature conditions drastically reduce the life span of synthetic-based building materials. Polystyrene loses its thermal properties due to the effect of "thermal drift" (when a special gas inside the polystyrene is replaced by ordinary air due to the diffusion effect, which occurs the faster, the higher the operating temperature) and due to thermal destruction. The loss of thermal efficiency by polystyrene leads, in turn, to an increase in the cost of heating and cooling the house and, as a result, to the need to replace the polymer insulation that has aged in the heat. The "bottleneck" of mineral wool in hot climates is resin - the most important element that ensures the binding properties and stability of the entire wool insulation. The most of resins used in mineral wool are not durable in hot environment and gradually deteriorate, due to which the mineral wool itself turns into dust. This behavior of synthetic materials (resins and polystyrene) is typical for countries with hot climates, such as Cyprus, since most insulation was originally developed to protect buildings from cold weather and were not intended to work for decades in hot climates.
MULTIPOR, unlike polystyrene and mineral wool, is not subject to thermal drift (since it does not have special gases in its composition) and does not collapse under the influence of high temperatures, since its binding material is cement - the same material that is used for foundations, beams and columns, floor slabs. The cement, as well as the sand and lime that are part of MULTIPOR, withstand perfectly the high temperatures on the roofs of Cyprus. Therefore MULTIPOR is the strongest and most durable solution for pitched roof insulation in Cyprus.

MULTIPOR does not accumulate moisture in the roof of a house

High humidity is a major problem for building materials and engineering systems used in the Cyprus climate. If the absolute humidity outside in the continental EU countries is usually 8-12 g / m3, then in Cyprus it can reach 25 g / m3 or even more! Such a high level of humidity reduces the thermal properties of both masonry and thermal insulation, increases the costs of drying and ventilation of a house, and provokes the appearance of mold. The vapor conductivity indicator is important as well when using thermal insulation inside wooden structures. Water condensation accumulating under polymer insulation (polystyrene, etc.) can lead to the appearance of mold on wooden structures and, as a result, to the need for a major overhaul of the roof. Therefore, not all building materials with a good reputation in countries with temperate or even cold climates are suitable for the climate of Cyprus.
Moreover, since in Cyprus the absolute humidity level is usually greater outside the building than inside, ventilation is not as effective when it comes to dehumidification compared to the continental and especially the northern EU countries. This is why we must consider the ability of building materials used in construction to protect buildings from excessive moisture.  Unlike polystyrene, MULTIPOR is able to absorb and move out excessive moisture from the walls and roofing elements of the building structure. The vapor transmission of MULTIPOR is approximately 50 times higher than XPS (extruded polystyrene) and 10-12 times higher compared to EPS (expanded polystyrene). This ability of MULTIPOR is even more important for wooden structures of a house, since wooden structures in a dry state have a significantly longer span life, stable geometry and good thermal insulation properties.

MULTIPOR's ability to dry a building - its walls and interior spaces - without annual maintenance or electricity consumption, for decades, is crucial to the humid climate of Cyprus!

A properly installed roof with MULTIPOR thermal insulation will keep your roof and its structures dry, which will save you money when operating your home for both cooling / heating and 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!

Absolute eco-friendliness

The MULTIPOR external thermal insulation composite system is sustainable and has received numerous awards for being environmentally friendly. The natureplus ecolabel, which is known for its high ecological standards, as well as the environmental declaration of the Institute of Construction and Environment, e.v., are a testament to the proven environmental and user friendliness of the Multipor mineral insulation boards, which consist purely of lime, sand, cement, and water.  These certificates also confirm the absence of any hazardous substances in the composition of MULTIPOR insulating boards, which makes them not only an excellent choice for external thermal insulation of buildings, but also an ideal choice in cases where floor, wall or ceiling insulation can only be done from the inside.
The remnants of MULTIPOR mineral insulation boards are 100% recyclable without polluting our planet. They can be either reuse into the production cycle (instead of thrown away), or use for other construction works.

Sustainability of MULTIPOR is very important both for nature and for our health. Using MULTIPOR makes our lives healthier and longer, reduces our medical costs and makes us happier

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.

Fast and easy installation

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.

Completely harmonized system

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.


MULTIPOR is not just a thermal insulation. In the climate of Cyprus, MULTIPOR allows you to solve many different problems aimed at reducing costs, as well as increasing the level of comfort and safety. Only MULTIPOR allows you at the same time:
- to dramatically and constantly reduce heating and cooling costs for the entire life of a building,
- to significantly reduce investment costs for climatic engineering systems, as well as future costs for their power supply and maintenance,
- to make the microclimate in the house healthier and eliminate mold appearance,
- significantly reduce or even completely eliminate the periodic repair work caused by wetting the walls under the polystyrene insulation, as well as the associated costs,
- to protect the house from external fires and minimize damage in case of fire inside the house.
