PVC profile manufacturers produce profiles with different dimensions and different features within each brand they produce. Each of these is called a series. The series differ from each other by differences such as shape, thickness, durability, longevity, and insulation properties.
The number of chambers affects the thermal and sound performance value of the window. As the number of chambers increases, the insulation values increase. However, this cannot be achieved with profile width alone. In addition, efficiency can be achieved by changing the outer wall thickness and the structure of the support sheet.
