Fakro PTP U3 uPVC Centre Pivot Roof Window
The FAKRO PTP U3 is a modern centre pivot roof window designed for rooms where moisture resistance, durability and easy maintenance are important. Its innovative construction combines multi-chamber white PVC-U profiles with aluminium elements and steel reinforcement, making it particularly well suited to humid areas such as bathrooms and kitchens.
The white finish also gives the window a clean, contemporary appearance that works well in spaces where an easy-to-clean roof window is preferred. Unlike timber, the PVC-U material does not absorb moisture, helping the window maintain its appearance and performance in environments with increased humidity.
Strong and Durable PVC-U Construction
The PTP U3 is manufactured using multi-chamber PVC-U profiles reinforced with steel. This construction provides excellent stability and helps prevent the profiles from warping over time. The window is also resistant to corrosion and weathering, making it suitable for long-term use in demanding environments.
The material has a high resistance to acids and alkalis and requires minimal maintenance. This makes the PTP U3 a practical option for homeowners looking for a roof window that can cope with the conditions found in kitchens, bathrooms and other moisture-prone areas.
Thermally Efficient Glazing
The PTP U3 features a thermo-insulating double-glazed unit incorporating a warm TGI spacer. The glazing consists of 4H-16-4T glass, with an external toughened pane and an internal Low-E pane.
The window has an overall U-value of 1.3 W/m²K, while the glazing has a U-value of 1.1 W/m²K. The glazing unit is also filled with argon gas, helping support its thermal performance. With an acoustic insulation rating of 33dB, the window can also help reduce external noise entering the room.
Improved Sealing and Weather Protection
The PTP U3 uses a triple tightening system designed to provide effective sealing around the window. This includes a clinging seal, a border seal and an additional seal integrated into the profiles covering the sides of the frame.
Externally, the window is protected by aluminium profiles coated on both sides with a durable polyester finish. The trapezium-shaped aluminium profiles are 1.0mm thick, providing increased durability and resistance to mechanical and transportation damage while helping protect the window from changing weather conditions.
Easy Operation and Ventilation
The PTP U3 features a modern white handle positioned at the bottom of the sash, making the window easy to operate. The handle also incorporates a two-step ventilation system, allowing you to introduce fresh air into the room without fully opening the window.
The centre pivot design provides straightforward everyday operation and makes routine cleaning and maintenance more convenient.
Modern Aluminium Exterior
The external aluminium profiles provide additional protection while complementing the appearance of the white PVC-U frame. The aluminium elements are designed to be durable and weather resistant, while the external appearance has been developed so that the PTP U3 retains a look similar to traditional timber roof windows.
The combination of PVC-U, steel reinforcement and aluminium provides a robust construction that is suitable for a wide range of residential applications.
