Pivot window PTP-X U41 GBMX

The pivot opening system with a mid-height hinge makes ventilation and window cleaning easy and convenient. The sash moves smoothly and stably, and the precise sash guiding mechanism allows for easy and trouble-free closing. The ergonomic handle allows for intuitive operation. The sash can be rotated 180° and locked allowing for safe cleaning of the outer pane. This functional solution guarantees everyday comfort of use.

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 white PVC profile (RAL 9003) blends harmoniously with any interior style, adding brightness and aesthetics, while its high moisture resistance allows the window to be installed in kitchens and bathrooms. Modern grey-brown (RAL 7022) 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 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

This modern external cladding, created in collaboration with the Institute of Industrial Design, combines protective function with aesthetic appeal. The grey-brown colour (RAL 7022) is a timeless choice that suits many types of roofs and façades. The consistent shade of the cladding, accessories and flashings ensures an aesthetically pleasing, uniform appearance and effective protection against the weather.

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.

Characteristic features of pivot roof windows

Our products stand out for what truly matters. Discover the features that make them reliable and exceptional in everyday use.

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.

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.

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.

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.
