Energy and acoustic efficiency
The 44 mm thick U41 triple-glazed unit combined with termoPro technology guarantees stable thermal comfort throughout all seasons. The Uw coefficient is rated at 1.1 W/m²K in a standard installation and 1.0 W/m²K with the EHV-AT Thermo flashing. The window effectively reduces energy loss in winter and protects the attic from overheating in summer, helping to lower building operating costs. In addition, flexible seals improve tightness and minimise the risk of thermal bridges. Sound insulation of Rw = 37 dB ensures quiet even in noisy environments, supporting everyday comfort.

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

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.

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
The internal profiles are made of high-quality PVC in an elegant white shade (RAL 9010), which suits most interior designs. Thanks to the V-PERFECT technology, the corners are aesthetically finished and joints are virtually invisible.. The smooth surface does not absorb moisture and is easy to maintain. The profiles meet Class A requirements according to the EN 12608 standard, which proves their high durability, structural strength and resistance to deformation.

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.
