Flat roof window DEC-M U8 (VSG) Z-Wave
Designed with everyday comfort in mind, the DEC-M U8 (VSG) Z-Wave model is a product intended for spaces where natural lighting and structural reliability are important. This electrically operated flat roof window is ideal for spaces where vertical windows cannot be installed due to the building’s layout. The matt dome diffuses the light, introducing a soft, gentle brightness into the interior without harsh reflections. Combined with a carefully selected glazing unit, it creates a pleasant, comfortable environment in rooms without traditional light sources.

Electric control and rain protection
The DEC-M U8 (VSG) Z-Wave window has been designed as a functional element of roof joinery, featuring electric opening option. It is controlled by a switch or remote control, allowing the sash to be tilted up to 12 cm, which enables effective room ventilation. The set includes a power supply unit and a rain sensor that automatically closes the window when first rain drops appear, ensuring comfort and safety of use. Thanks to Z-Wave radio technology, control is wireless, allowing the window to be integrated with a Smart Home system via a dedicated gateway.

Functional solution for flat roofs
The electrically operated DEC-M U8 (VSG) Z-Wave window is designed for installation on flat roofs with pitches from 0° to 15°. It is also possible to use the XRD and XRD/W installation base, which allows the window to be raised and installed on green, gravel or ventilated roofs. Its simple design means that the product fits in with a variety of architectural styles and blends in perfectly with modern, minimalist spaces. The window can be equipped with internal accessories and an external awning blind, enhancing the comfort of the attic space.
Dome
The window canopy is made of durable polycarbonate, which is highly resistant to impact and adverse weather conditions. Its matt structure allows the interior to be illuminated with soft, diffused light while simultaneously limiting the penetration of harmful UV radiation. Additional protective coatings applied to both sides of the surface increase the material’s durability and ensure an aesthetic appearance for a long period of use.

Glazing unit U8
The window features a passive, triple-chamber U8 glazing unit filled with noble gas - krypton. The internal P2A class laminated glass provides a basic level of protection against forced entry. The outer toughened glass is covered by a lifetime hail resistance warranty, increasing the level of safety and reliability even in harsh weather conditions. The entire window has a heat transfer coefficient rated at 0.72 W/m²K, ensuring very good thermal insulation.

Frame
The window structure is based on a frame made of white PVC profiles (RAL 9010) with a multi-chamber design filled with insulating material. As a result, the frame is highly resistant to moisture, which makes it ideal for rooms with high humidity, such as bathrooms or laundry rooms. The entire structure is durable and does not require regular maintenance, and its light colour scheme makes it easy to match with a variety of interior designs.

Actuator
The integrated electric drive operating in Z-Wave technology ensures comfortable everyday use, enabling convenient remote operation with both a remote control and a wall switch. The sash can be opened to 120 mm, allowing for effective ventilation. The durable construction of the mechanism ensures a long service life, and the possibility of integration with home automation further enhances user comfort.

Rain sensor
When rainfall is detected, the ZRD rain sensor mounted on the window sash sends a signal to the actuator, triggering the automatic closure of the roof window. The rain sensor is a practical, convenient solution that increases safety and comfort in everyday use. It is maintenance-free, requires no programming and effectively protects the interior from flooding, even when the occupants are away.

Characteristic features of flat roof windows type C
Our products stand out for what truly matters. Discover the features that make them reliable and exceptional in everyday use.
Interior lighting

The use of polycarbonate domes allows natural light to be effectively brought into rooms located under a flat roof. The transparent surface and protective coatings reduce UV radiation penetration and maintain the product's aesthetic appeal for a long time.
Safety of use

Toughened external glass and P2A class laminated internal glass provide effective protection against mechanical damage, including hailstorms. The design of individual models meets high standards of durability and resistance, which translates into reliability in difficult weather conditions.
Energy-efficient design

PVC profiles with thermal insulation filling and carefully selected glazing units reduce heat loss, supporting thermal comfort in the building. The insulation parameters reach levels suitable for both standard construction and houses with increased energy requirements.
