When you plan to buy new windows for your home, you should bear in mind that it is a long-term investment, as the windows you purchase should serve you well for many years. Not everyone does adequate research into the product they’re buying, but it is crucially important that the decision you make on your window supplier is a well-informed one. There are many factors that distinguish high-quality products from poor-quality ones.
Except for visual quality and design that matches the building’ architecture, you should also take comfort of use and, above all, the protection level against external factors into account. That is why it is worth learning the parameters that should be borne in mind when choosing the window and formulating the questions to ask the salesperson before making the final decision.
In a nutshell, the window profile is the structure of the window that makes it rigid and holds the glass panel in place. The profile consists of the frame, the sash, the mullions and glazing beads.
There are three different classes of profiles—A, B or C. A is the highest class, which means that the exterior walls of the window are 3-mm thick and the internal chambers is 5 mm wide.
