The use of fossil fuels to produce energy creates greenhouse gases. These gases trap energy in the atmosphere making the Earth grow warmer. As a result, the built up of greenhouse gases create a negative impact on the climate pattern, altering them drastically and threatening human health and ecosystems. A well insulated building can save energy up to 50%.
5.1 Aluminium systems and thermal insulation
Energy loss from window and door openings can reach 25%. This is an important piece of information that needs to be addressed when thermal insulation of a building is under consideration. The thermal insulation aluminium frames have specially designed components and EPDM gaskets that are mounted between the internal and external parts of an aluminium profile, in order to seal the sash of the frame when in rest position. In Cyprus according to the ‘Energy Performance of Buildings Directive’ published by the Energy Service of the Ministry of Energy, Commerce, Industry and Tourism, the thermal transmittance coefficient Uw for every frame must be less than or equal to 3,8 W/m2K.
5.2 The benefits of thermal insulation systems
• Reduced heat loss from the interior of the building during winter months and reduced heat transfer from external high temperatures during hot weather.
• Improved thermal transmittance values by 40-70%
