The lower element of the FOX P50 APXX terrace window is a solution for users who want to fully utilise the potential of the knee wall, increasing the amount of daylight and the field of view. Installed below a roof window, it creates a visually cohesive glazed surface and enhances the modern character of the interior. The fixed design improves operational safety – as it cannot be opened, it eliminates the risk of accidental opening. The window is specially profiled and designed to be combined with FOP‑V or FOP‑X roof windows, forming a terrace window system.

The P50 triple‑glazed unit with a thickness of 44 mm, combined with thermoPro technology, ensures high thermal insulation and a stable indoor temperature throughout the year. The Uw heat transfer coefficient is 1.1 W/m²K when used with the EHV‑AT Thermo flashing, resulting in lower heating costs. Flexible seals improve window tightness and minimise the risk of thermal bridging. Very good acoustic insulation ensures peace and quiet even in noisy environments, effectively reducing external noise.

The window is made of the highest‑quality pinewood, vacuum impregnated and coated with clear acrylic lacquer. The natural finish enhances the elegance of the interior, while the modern anthracite cladding (RAL 7016) blends perfectly with the building, creating a consistent visual effect that highlights the overall aesthetics of the structure.

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, vacuum impregnated and coated with a clear acrylic varnish, emphasises the natural character of the wood. This makes your interior cosy, warm and elegant. The finish is durable and resistant to everyday use, maintaining its aesthetic appearance for many years.

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.
