The raised axis of rotation makes everyday use of the window exceptionally convenient. The sash lifts higher than in traditional models, allowing easy access to the edge without restricting views outside. Even tall people can operate it comfortably without having to bend down. The pivot opening mechanism with the sash guiding system operate smoothly. The sash can be rotated 160° and locked allowing for safe cleaning of the outer pane.

The 44 mm thick U41 triple-glazed unit combined with termoPro technology guarantees stable thermal comfort throughout all seasons. The Uw coefficient is rated at 1.1 W/m²K in a standard installation. The window effectively reduces energy loss in winter and protects the attic from overheating in summer, helping to lower building operating costs. In addition, flexible seals improve tightness and minimise the risk of thermal bridges. Sound insulation of Rw = 35 dB ensures quiet even in noisy environments, supporting everyday comfort.

Vacuum impregnated pinewood coated with clear acrylic varnish highlights the natural grain and creates an elegant setting for residential interiors. Modern anthracite (RAL 7016) cladding emphasises the minimalist character of the window and matches contemporary roofs. As there is no inlet, the tightness and acoustic parameters are improved, making this model ideal for bedrooms, living rooms and children's rooms, where silence, safety and thermal comfort are a priority.
Glazing unit U41
The 44 mm thick triple-glazed unit features two low-emission coatings, glazing cavity filled with argon and warm TGI spacer. This gives the window a very good heat transfer coefficient of Uw = 1.0 W/m²K. It provides acoustic comfort of 35 dB, effectively reducing noise and improving relaxation conditions in the attic.

External cladding
The external cladding was designed in cooperation with the Institute of Industrial Design. Its modern, minimalist form emphasises the aesthetics of the window and harmonises with the roof line. The anthracite colour (RAL 7016) fits perfectly with current architectural trends. The colour consistency of the cladding, accessories and flashings creates a harmonious, elegant set that is resistant to weather conditions.

Internal finish
Carefully selected pinewood, laminated and coated with three layers of polyurethane varnish, which creates a durable, moisture-resistant and perfectly smooth coating in white (similar to RAL 9003). The lack of visible grain emphasises the modern, minimalist style. This finish is ideal for kitchens, bathrooms and anywhere where aesthetics and functionality are important.

Handle
The handle positioned at the bottom of the sash ensures comfortable and natural window operation. It allows easy opening, tilting and closing, and thanks to the micro‑opening function, it enables safe and controlled ventilation of the interior. For larger models (with a width above 98 cm), two handles are used, which makes operating the sash easier and ensures even, airtight closing.

Locking bolt
A special locking bolt allows the sash to be secured in the fully rotated 180° position. This enables safe, comfortable and independent cleaning of the outer pane, without the need to go onto the roof or use professional services. This simple solution makes maintaining and cleaning roof windows significantly easier.

Glass
The extenal toughened glass in the U41 glazing unit is damage-resistant and comes with a lifetime hail warranty. It ensures durability and window protection against extreme weather conditions.
