Durability and Longevity

In the case of residential construction, so-called ‘warm’ aluminium profiles are becoming increasingly popular. This means that the profile construction consists of two metal sections, joined by a thermal plastic insert, such as glass fibre-reinforced polyamide. Such a profile generally has three or four chambers, with additional polymer foam filling in the middle chamber.


Additionally, rollers can be made from different materials, including nylon, metal, and composite materials. Nylon rollers are popular due to their quiet operation and resistance to corrosion. Metal rollers, on the other hand, provide increased durability, making them ideal for heavier windows.
