Security Features
Rollers for aluminum sliding windows come in various designs, catering to the specific needs and preferences of users. Generally, there are two main types of rollers top-mounted and bottom-mounted.
The window profile, or window frame, can be made mainly from three different materials: plastic, i.e. PVC, wood and aluminium. Plastic profiles are the most common and the most economical. Laminated timber frames are valued for their naturalness and rigidity, which is particularly important for larger patio windows. However, they are more expensive, heavier and require regular maintenance. Aluminium profiles, on the other hand, although they have the highest cost, are the most rigid, durable and maintenance-free. This is why their share of the market is steadily increasing, although due primarily to their high price, they still do not exceed a few percent.
