Pivot window with raised axis of rotation with lower transom FDU-X P50 AUMX

The pivot design with an additional lower transom allows for easy ventilation and convenient operation. The hinge positioned in the middle of the sash height ensures smooth and stable movement, while the pivot mechanism with a sash guidance system operates smoothly and the 160° lock facilitates safe cleaning of the glass from the outside. An additional pane in the bottom section illuminates the room, eliminating the need to combine two separate windows.

Energy and acoustic efficiency

The 44 mm thick P50 triple-glazed unit combined with thermoPro technology guarantees high thermal insulation throughout the year. The Uw coefficient is 1.1 W/m²K in a standard installation and 1.0 W/m²K with the EHV-AT Thermo flashing. The multi-chamber frame design and carefully designed seals reduce thermal bridges and improve tightness. Very good sound insulation of Rw = 37 dB keeps the room quiet even with intense noise from outside, which contributes to greater comfort in everyday use.

Aesthetics and durability for years to come

The inner surface of the sash is coated three times with white polyurethane varnish (RAL 9003), which creates an elegant, smooth and durable finish. This solution makes the window ideal for rooms with high humidity, such as kitchens or bathrooms, maintaining its aesthetic appearance for years. On the outside, modern anthracite-coloured cladding (RAL 7016) gives the entire structure a minimalist character and blends in with contemporary roof architecture, creating a consistent look for the entire building.

Glazing unit P50

The 44 mm thick triple-glazed unit has been designed for excellent thermal and acoustic insulation. Toughened outer pane, laminated inner pane, argon and soundproofing film effectively increase user comfort. In combination with the Thermo flashing, the entire window achieves a heat transfer coefficient of Uw = 1.1 W/m²K. The design reduces noise to 37 dB, and the easy-to-clean coating makes it easy to keep the glass clean.

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 P50 glazing unit ensures durability, safety and high comfort of use. The toughened outer glass is damage-resistant and comes with a lifetime hail warranty. The internal P2A class laminated glass increases safety by reducing the risk of injury in the event of breakage and makes it more difficult to force the window open during a break-in attempt. An additional acoustic film improves sound insulation, and the easy-to-clean coating makes cleaning the outer glass easier.

Characteristic features

Our products stand out for what truly matters. Discover the features that make them reliable and exceptional in everyday use.

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

The window is manufactured from FSC-certified wood and coated with water-based varnishes. Choosing this solution supports environmental protection and 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.

Soundproofing

A triple-glazed unit with acoustic film and laminated glass effectively decreases noise by 37 dB. This improves acoustic comfort inside rooms by reducing street noise, neighbours' conversations and the sounds of everyday activities, among other things.

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.
