UPVC WINDOWS ALWAYS ADAPT TO YOUR NEEDS – PART 2
The number of chambers is not only important value to follow The outer wall of the uPVC profiles is usually 2.8-3 mm thick, with the inner cavity of the profile divided by partitions into several chambers. Usually, more chambers mean better thermal insulation properties. What is more significant than the number of chambers is the coefficient of heat transfer through the frame - the lower the coefficient, the lower the heat losses across the profile. On the other hand, fewer chambers mean more space for steel reinforcement, which can then be more massive. The greater the window size, the higher the requirement is for the static load-bearing capacity that the metal reinforcement provides. These design elements determine the maximum size of the windows that can be produced from the profile type. The uPVC windows are excellently proven both in the construction of new family houses and in the reconstruction of older houses because of their variable capabilities. ...
