Pivot window with raised axis of rotation FYP-V U41 APMX
The raised axis of rotation makes everyday use of the window exceptionally convenient. The sash lifts higher than in traditional models, allowing easy access to the edge without restricting views outside. Even tall people can operate it comfortably without having to bend down. The pivot opening mechanism with the sash guiding system operate smoothly. The sash can be rotated 160° and locked allowing for safe cleaning of the outer pane.

Energy and acoustic efficiency
The U41 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. In addition, flexible seals support system airtightness and help minimise the risk of thermal bridging when properly installed and combined with compatible accessories. Sound insulation of Rw = 35 dB helps reduce external noise and may contribute to improved acoustic comfort indoors.

Aesthetics and durability
Vacuum impregnated pinewood coated with clear acrylic varnish highlights the natural grain and creates an elegant setting for residential interiors. Modern anthracite (RAL 7016) cladding emphasises the minimalist character of the window and matches contemporary roofs. As there is no inlet, the tightness and acoustic parameters are improved, making this model ideal for bedrooms, living rooms and children's rooms, where silence, safety and thermal comfort are a priority.

Glazing unit U41
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. It provides acoustic comfort of 35 dB, effectively reducing noise and improving relaxation conditions in the attic.

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.

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.


Glass
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.
