Pivot window with raised axis of rotation with lower transom FDU-V 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 P50 triple-glazed unit, combined with thermoPro technology, supports high thermal insulation performance throughout the year. The Uw value is 1.1 W/m²K in the standard installation configuration and 1.0 W/m²K when installed with the EHV-AT Thermo flashing. These parameters may help reduce heat loss, although the actual effect depends on the installation quality, building standard, and usage conditions. The multi-chamber frame design and carefully engineered sealing system help reduce thermal bridging and support weathertightness when installed correctly and used with appropriately selected accessories. Sound insulation rated at Rw = 37 dB helps reduce external noise and may contribute to improved acoustic comfort indoors.

Aesthetics and durability
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 Supports good thermal insulation performance of the window throughout the year. The thermal transmittance coefficient is 1.1 W/m²K when installed with the EHV-AT Thermo flashing. These parameters may help reduce heat loss, although the actual effect depends on the installation quality, building standard, and usage conditions. The multi-chamber frame design and flexible seals support weathertightness and help reduce the risk of thermal bridging when installed correctly and used with appropriately selected accessories. 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 combines features that support durability, security, and user comfort. The toughened outer pane helps increase resistance to damage, while protection against hail damage is covered by a lifetime warranty in accordance with its terms and conditions. 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.

Air inlet
The air inlet used in the window adjusts the amount of incoming air according to wind pressure, reducing excessive drafts and noise. This ensures effective room ventilation while maintaining quiet operation and optimal acoustic and thermal comfort. The air inlet protects the interior from excessive humidity and supports a healthy indoor microclimate.

Key features
Our products stand out where it really counts. Discover the features that make them reliable and built to last.
thermoPro technology

The thermoPro technology supports the window's thermal insulation performance, helping to reduce heat loss in winter and limit indoor heat build-up during summer. When installed correctly, it may contribute to improved thermal comfort and more efficient energy use.
topSafe system

The topSafe system enhances security thanks to reinforced window construction and resistance to break-in attempts or accidental opening, helping to enhance your family's sense of safety and comfort at home.
Environmentally conscious solution

The window is manufactured from FSC-certified wood and finished with water-based coatings.
Easy-to-clean coating

The easy-to-clean coating makes it easier to keep the outer pane clean. When exposed to sunlight and rain, it may help reduce the build-up of common contaminants such as dust and pollen.
Soundproofing

The triple-glazed unit featuring an acoustic film and laminated pane helps reduce external noise, potentially enhancing acoustic comfort indoors.
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.
