Type Z windows
Windows with flat, aesthetically finished glass, under which there is an electrically controlled awning blind.
Type Z flat roof windows - light, comfort and technology hidden in detail
Interiors without traditional vertical windows require solutions that allow natural light to enter and ensure a pleasant microclimate at any time of the year. Type Z flat roof windows were designed with such spaces in mind – they combine a modern look, high thermal insulation and everyday convenience. They feature a carefully designed glass segment, a factory-integrated awning blind in the Z-Wave system and a glazing unit that ensures safety and durability. This solution is suitable for both residential and public buildings, creating bright, comfortable interiors regardless of external conditions.
Glass segment aesthetics
A characteristic feature of type Z windows is a glass segment with a slight slope on the outer surface. This shape allows rainwater or melting snow to drain freely, even when the window is installed completely horizontally. In practice, this means that the roof remains completely watertight, while gaining an elegant, minimalist architectural detail. The glass pane, bonded around the entire perimeter, enhances the structure's stability, while darkened edges conceal the joints, giving the entire structure a harmonious appearance. From the outside, the structure is complemented by a black aluminium profile (RAL 9005), which creates a consistent contrast with the roof surface and emphasises the modern character of the building.
Thermal comfort all year round
Each model in this category is equipped with the P2 glazing unit, which effectively combines safety with energy efficiency. The outer toughened glass, covered by a lifetime hail resistance warranty, protects against adverse weather conditions, while the inner P2A laminated glass increases damage resistance and improves user safety. The heat transfer coefficient Uw of 0.95 W/m²K keeps interiors warm in winter without the risk of excessive energy loss and maintains a comfortable temperature in summer when the roof heats up in the sun. This insulation ensures a stable indoor climate, which translates into lower energy bills and greater comfort in everyday use.
Durability and resistance in everyday use
The frame is made of white PVC profiles with a multi-chamber structure filled with insulating material, providing a solid base for the entire structure. Such a frame is moisture-resistant and easy to keep clean, which is why it works well even in rooms with high humidity, such as bathrooms, laundry rooms and kitchens. The light colour scheme on the inside allows it to match many interior designs, and no need for regular maintenance makes this solution convenient and practical for everyday use. All elements have been designed to maintain durability and aesthetics for many years, regardless of the intensity of use or changing weather conditions.
