GREENVIEW windows are your piggy bank in the roof

Saving money can take many forms. Some people put coins in a piggy bank while others look for ways to keep money in their wallets. FAKRO GREENVIEW roof windows belong to the latter group. These products have a real impact on home energy consumption. Their design has been developed to reduce heat loss and ensure an optimal microclimate in the attic. Energy efficiency in this case is not a coincidence, but the result of precise engineering. Every element of the window – from the glazing to the frame and the installation method – works together to retain heat inside the building.

GREENVIEW roof windows equipped with the P50 triple-glazed unit feature a modern, 44-millimetre glazing unit with high insulation performance. This is what effectively retains heat inside the room and reduces energy loss. The glazing consists of three glass panes separated by spaces filled with argon, a noble gas that creates a barrier against cold. Additional low-emission coatings reflect heat back into the building, enhancing the insulating effect. This design ensures a stable temperature in the attic year-round as it limits cooling in winter and prevents overheating in summer. The P50 glazing unit is a key element that reduces the energy consumption needed to heat and cool your home, improving everyday comfort.

Energy efficiency does not depend solely on the glass, but also on how airtight and stable the entire structure is. GREENVIEW windows use the thermoPro technology, which optimises temperature distribution and increases the joint tightness. Thermally insulating inserts are incorporated into the frame, eliminating areas where heat could escape. Water drainage channels are located in the corners to prevent moisture build-up in the structure. The new sealing system reduces air flow and improves overall thermal efficiency. Windows manufactured using this technology achieve the highest, fourth class of tightness according to EN 12207. In practice, this means that cold air does not penetrate inside, and heated air remains in the room. The thermoPro is a solution that improves the thermal performance and durability of windows for years to come.

 

 

Another element contributing to energy efficiency is the warm spacer placed between the glass panes. The edges of the glazing unit – regardless of the window type, unit structure or manufacturer – are always its coldest area. It is there, on the spacer, that the temperature drops the most, promoting the formation of thermal bridges. Applying the TGI warm spacer made of a material with low thermal conductivity significantly reduces this effect. It maintains a more even temperature across the entire glass surface and reduces the risk of water vapour condensation. As a result, the thermal insulation of the window is improved and the entire glazing unit performs more stably in changing weather conditions. This small detail significantly increases the window's energy efficiency.

In the new GREENVIEW design, the glazing unit is set deeper into the sash profile. This solution increases the thermal insulation of the entire window as it provides better protection for the edges of the unit – the coldest zone of each pane. Deeper setting also improves thermal and structural stability, which translates into lower energy losses. As a result, heat stays inside longer and the heating system can operate with less load. This makes energy consumption decreased and the user experiences greater thermal comfort. This solution naturally fits in with the idea of sustainable construction and real operating savings.

 

 

A window can only fully perform its function when properly installed. The Thermo flashing plays a crucial role in the GREENVIEW system, increasing the insulation of the set by up to 15%. Its insulation layer tightly surrounds the frame and reduces the formation of thermal bridges. The system is complemented by installation accessories, such as the XDP Plus insulation kit and XWT Plus insulation band, which ensure a proper connection between the window and the roof. Professional installation by a certified specialist allows for the full use of the structure's thermal potential. Only then can you talk about real energy efficiency, measured in stable temperatures and lower heating bills.

FAKRO GREENVIEW roof windows combine modern technologies with precise workmanship. The glazing unit, thermoPro technology, warm spacer, deeper glazing and system installation create an integrated combination that effectively reduces heat loss. Each of these elements plays a specific role in improving energy efficiency.

GREENVIEW is not only a source of natural light, but above all a solution that supports a better heat balance in the building – especially when compared to older generation structures. The new window reduces energy loss, allowing the heating to work more efficiently and the house to become noticeably warmer.

They can be compared to a modern piggy bank, which instead of coins collects savings in the form of energy that does not need to be used. This is energy efficiency that works quietly, consistently and every day.
