FPU-X MAX U41 AUMX

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 when installed with the Thermo flashing. It provides acoustic comfort of 37 dB, effectively reducing noise and improving relaxation conditions in the attic.

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.

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.

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.

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.

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.
