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.

Aesthetics and durability for years to come
The window's internal profile, finished in an elegant anthracite veneer, harmonises with modern interiors, emphasising their stylish character. The PVC surface is resistant to moisture, making the window particularly suitable for kitchens and bathrooms. The external cladding in the same anthracite colour (RAL 7016) gives it a consistent and minimalist look, perfectly suited to contemporary roofs. This is a solution for those seeking to combine functionality with modern aesthetics.
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.

thermoPro technology
The thermoPro technology provides effective thermal insulation, minimising heat loss in winter and protecting against overheating in summer. This solution guarantees year-round thermal comfort and noticeable energy savings.

topSafe system
The topSafe system enhances security thanks to reinforced window construction and resistance to break-in attempts or accidental opening. Your family gains peace of mind and complete home protection.

Environmentally conscious solution
PVC windows are largely made from recycled materials and are almost entirely recyclable. This makes them an environmentally friendly solution and supports the idea of sustainable construction.

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.

Durable protection
The U41 glazing unit is a durable solution that provides reliable protection against external factors. The external toughened glass increases resistance to damage and is covered by a lifetime hail damage warranty.

Flashing
For correct roof window installation, it is necessary to use a flashing, selected according to your individual needs.
