Aluminum is the ideal material for the construction of windows, because it undoubtedly gathers a multitude of advantages. It is a material that combines high mechanical strength, impeccable aesthetics, with "unlimited" lifespan, as well as the minimum maintenance requirement.
It is understood by everyone that unsuitable frames and windows are responsible for the heat loss of the interiors. In areas of Greece where there are respectively high temperatures in summer and low in winter, the need to use thermal break aluminum systems is considered necessary. Replacing the single glazing with double glazing reduces energy consumption by 32%, while with simultaneous insulation of the exterior walls, the savings can reach up to 50%. The use of aluminum frames that have thermal break, compared to the simple "cold", reduces heat loss from the frames to 1/3 and contributes to the reduction of heating costs by 1/5.

Another key factor in selecting windows with thermal break specifications is the protection of the frames and their adjacent surfaces from the phenomenon of liquefaction. Aluminum is a good conductor of heat and transports cold inside the surface of the window. This causes the indoor hot air to come in contact with the cold surface of the aluminum and liquefy. Thus, on very cold winter days, there is intense liquefaction and runoff of water from the aluminum surface with the risk of damaging nearby walls, floors and objects that will come in contact with water.

The thermal break window contains a special insulating material, called polyamide. The polyamide is inserted between the outer and inner surface (rod) of the profile, to be then stapled together to form a single profile. As a bad conductor of heat, it "interrupts" the influence of the external temperature on the inner surface of the window, eliminating the phenomenon of liquefaction and consequently all the resulting problems.
