The frame should prevent or at least reduce the heat transfer from the interior to the exterior and vice versa.
It depends on the materials of the frame, the sealing and on the type of glass. This property is called thermal insulation . Below you can find the basic definitions of heat and temperature, in order to provide a better understanding of how thermal insulation works.
Heat - Temperature
According to physics, heat is "the energy that causes the motion of atoms and molecules," which constitutes a body. The increase of energy, hence the motion, causes heating while the reduction results in cooling.
Temperature is the measure describing the thermal state of an object.
Meaning the cessation of heat transfer
Thermal bridges achieved by the separation of aluminium profiles into 2 parts and adding insulating materials (polyamide) separating the inner from the outer surface. This reduces the heat transfer (or cooling) between the exterior and the interior environment.
Nowadays, all the insulating aluminum frames are using this solution to achieve thermal insulation. The polyamide is used as the main building material achieving high performance in terms of mechanical strength, chemical treatments and thermal insulation. It also offers the ability to be colored while its expansion is similar to the one of aluminium.
The scale for measuring the insulation is 4108 and the coefficient K or U. The U is used to characterize the flow of heat through a material or component.
The material's coefficient is defined as the amount of heat that passes through each square meter of the construction element when the temperature difference of the stationary air tangential to the two surfaces of the element is kept constant and equal to the first C.
The overriding conclusion is that the lower the coefficient is , the more powerful the insulating element is. Depending on the value of the factor, it is classified into a category based on specifications (GRUPPE). Taking into account that the possible values of the coefficients are compared with their difference in absolute numbers (eg factor 2.1 with a factor of 3). In fact due to the calculation of the factor (logarithmic scale) the difference in insulation between a frame with a factor rate of 2.1 compared to one that has a factor of three is very large.
The technology and quality of the frames play an important role in the optimal energy planning and management of a building, as they are a vital part of the building's insulation.
