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.
