The RoofLITE+ FRE B600 Electric Opening Flat Roof Window Base Unit is designed to bring natural daylight and fresh air into rooms beneath flat and low pitched roofs. Featuring electric opening, a wireless wall switch and an integrated rain sensor, it provides convenient ventilation at the touch of a button while delivering excellent thermal performance and modern styling.
Manufactured from internally insulated white PVC, the FRE B600 is ideal for extensions, kitchens, living spaces and other rooms where both overhead daylight and controllable ventilation are required.
The FRE B600 is the electrically opening base unit of the complete RoofLITE+ flat glass roof window system and must be installed together with the compatible RoofLITE+ FGT200 Flat Glass Module, which is sold separately. Both components are required for a complete installation.
The RoofLITE+ FRE B600 features an integrated electric motor that allows the upper section of the window to open by up to 20cm.
This provides convenient ventilation and allows fresh air to circulate through the room without the need to manually operate the window.
The electric opening makes the FRE B600 particularly suitable for:
The RoofLITE+ FRE B600 is operated using the supplied wireless wall switch, allowing you to open and close the window conveniently from inside the room.
The control is factory paired with the window for straightforward setup and everyday operation.
The system is also io-homecontrol® compatible, allowing integration with compatible smart home control systems.
An integrated rain sensor provides additional peace of mind by automatically closing the window when rainfall is detected.
This means you can ventilate your home without constantly monitoring changing weather conditions.
If rain begins while the window is open, the system automatically activates the electric motor to close the window and help protect your interior.
The RoofLITE+ FRE B600 features a specially designed frame structure that extends into the room, helping maximise the amount of natural daylight entering the space below.
This creates brighter, more welcoming interiors while helping reduce reliance on artificial lighting during the day.
The RoofLITE+ FRE flat roof window system consists of two separate components:
The FGT200 top module is a mandatory component and must be purchased separately.
Both components are required for correct installation and to create the complete RoofLITE+ electric flat glass roof window system.
The RoofLITE+ FRE B600 features a laminated inner safety pane designed to remain held together in the unlikely event of breakage.
This helps prevent dangerous glass fragments from falling into the room below.
When combined with the mandatory FGT200 Flat Glass Module, which features toughened external glass, the complete system provides enhanced resistance against glass breakage from both inside and outside.
When combined with the required FGT200 Flat Glass Module, the complete roof window benefits from a special self-cleaning coating on the external glass.
This coating helps reduce the accumulation of dirt and significantly reduces the amount of manual cleaning required, particularly useful for overhead glazing that may otherwise be difficult to access.
The RoofLITE+ FRE B600 features an internally insulated white PVC frame and insulation filled covering elements to help minimise heat loss.
Reference thermal performance:
This high level of insulation helps create a comfortable indoor environment while reducing unwanted heat loss through the roof.
The advanced glazing system and insulated construction help reduce noise from outside.
With a sound reduction rating of 31dB, the FRE B600 helps minimise disruption from rainfall and everyday external noise, creating a more comfortable interior.
The electric motor and operating cables are concealed within the window frame, providing a clean and uncluttered appearance from inside the room.
The smooth white PVC internal finish complements modern interiors and is easy to maintain.
The RoofLITE+ FRE B600 can be installed on roofs with pitches between 5° and 15°, making it suitable for a wide variety of flat roof extensions and low pitch roofing projects.
The system uses a proven installation method familiar to professional roofers and installers.
Installation instructions, screws and the necessary drill bits are supplied to simplify the fitting process.
