Sliding windows

Sliding windows and doors are not only aesthetic, but also very practical. They can be made much larger than turn windows and doors. They are perfect for obtaining more light in the room and great views, they are a modern component of any interior. Sliding windows are also practical and comfortable for partitioning terrace, balcony and house or flat interior area.

The developing technologies of profile systems, as well as the expanding options of fittings, enable the design of products in very large sizes and weight of up to several hundred kilograms, without any impact on failure-free use for many years.
