The non-opening window installed in the vertical combination beneath the opening window is an excellent complement to a roof‑window set. It increases the glazed surface area, providing optimal natural illumination and offering a panoramic view of the sky. The reduced number of profiles gives the structure a modern, refined appearance that perfectly fits current interior‑design trends. The flush installation, without a connecting trim, ensures a seamless, uniform glass line that enhances the harmony of the entire composition.

The 44 mm P50 triple‑glazed unit combined with thermoPro technology provides excellent thermal insulation and stable indoor temperatures throughout the year. The Uw heat transfer coefficient of 1.0 W/m²K translates into lower heating costs. Flexible seals improve the airtightness of the window and minimise the risk of thermal bridging.

The window is made of multi‑chamber PVC profiles in white (RAL 9003), which are resistant to moisture, dirt and deformation. The profile surfaces do not require painting or complicated maintenance, making the window ideal for rooms with increased humidity such as kitchens or bathrooms. Its modern design and elegant finish complement a wide range of interior styles. The external cladding in the fashionable anthracite colour (RAL 7016) enhances the window’s aesthetics and blends harmoniously with the roof covering.
The 44 mm thick triple-glazed unit has been designed for high thermal and acoustic insulation. Toughened outer pane, laminated inner pane, argon and soundproofing film effectively increase user comfort. The entire window achieves a heat transfer coefficient of Uw = 1.0 W/m²K.

Characteristic features of non-opening combination window
Nasze produkty wyróżniają się tym, co naprawdę ma znaczenie. Poznaj cechy, które czynią je niezawodnymi i wyjątkowymi w codziennym użytkowaniu.

thermoPro technology
The thermoPro technology provides effective thermal insulation, minimising heat loss in winter and protecting against overheating in summer. This solution guarantees year-round thermal comfort and noticeable energy savings.

topSafe system
The topSafe system enhances security thanks to reinforced window construction and resistance to break-in attempts or accidental opening. Your family gains peace of mind and complete home protection.

Environmentally conscious solution
PVC windows are largely made from recycled materials and are almost entirely recyclable. This makes them an environmentally friendly solution and supports the idea of sustainable construction.

Easy-to-clean coating
The easy-to-clean coating keeps the outer pane clean for longer. Dirt such as dust and pollen is broken down by sunlight and washed away by rain. This saves you time and means you don't have to clean your windows as often.

Design
The modern design of the cladding, developed in cooperation with the Institute of Industrial Design, emphasises the minimalist aesthetics of the window. Three colours – anthracite (RAL 7016), black (RAL 9005) and grey-brown (RAL 7022) – allow for a consistent match with the roof and accessories.

Durable protection
The P50 glazing unit ensures durability and safety. The external toughened glass comes with a lifetime hail resistance warranty. The internal P2A class laminated glass protects against injury in the event of breakage and makes it difficult to force the window during a break-in attempt.

Flashing
For correct roof window installation, it is necessary to use a flashing, selected according to your individual needs.
