The number of chambers in a PVC profile determines the window’s thermal and sound insulation performance. 5-chamber profiles offer an optimal balance between cost and quality, providing excellent insulation for most standard needs. They are ideal for moderate climates and buildings without extreme insulation requirements.
In contrast, 7-chamber profiles are designed for those seeking maximum energy efficiency and top insulation performance. These profiles are especially suitable for areas with large temperature variations, significantly reducing heating and cooling costs. Although they require a slightly higher initial investment, they deliver greater long-term energy savings and improved living quality.
It’s important to note that the number of chambers must be aligned with the profile’s width—more chambers have no effect if there isn’t enough depth to create sufficient air pockets. Always check the manufacturer’s certificates to ensure the selected profile meets performance standards.
