The RoofLITE+ FRF B600 Fixed Flat Roof Window Base Unit is designed to bring more natural daylight into rooms beneath flat and low pitched roofs. Featuring a thermally insulated white PVC construction, laminated safety glazing and excellent acoustic performance, it provides a modern and energy efficient daylight solution for extensions, kitchens, living spaces and other areas where additional ventilation is not required.
The FRF B600 is the fixed 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 to create a complete flat roof window installation.
The RoofLITE+ FRF B600 features a specially designed frame structure that extends into the room, helping maximise the amount of natural daylight entering the space below.
This makes it an excellent choice for:
The large glazed area helps create brighter, more welcoming interiors while reducing reliance on artificial lighting during the day.
The FRF B600 is a non-opening flat roof window base unit, making it ideal for rooms where natural daylight is the priority and additional ventilation is not required.
As there are no opening mechanisms or motors, the fixed design provides a simple and dependable solution for introducing overhead daylight.
If you require additional ventilation, consider the RoofLITE+ FRE Electric Flat Roof Window, which provides electrically operated opening.
The RoofLITE+ FRF 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+ flat glass roof window system.
Safety is an important consideration with overhead glazing, which is why the RoofLITE+ FRF B600 features a laminated inner pane.
The laminated glass is designed to remain held together in the unlikely event of breakage, helping prevent dangerous glass fragments from falling into the room below.
When combined with the compatible FGT200 Flat Glass Module, which features toughened external glass, the complete system provides enhanced resistance to glass breakage from both inside and outside.
Roof windows can be exposed directly to rain and other external noise, so acoustic performance is particularly important.
The RoofLITE+ FRF B600 provides a sound reduction rating of 36dB, helping reduce external noise and the sound of rainfall for a quieter, more comfortable indoor environment.
When combined with the required FGT200 Flat Glass Module, the complete RoofLITE+ flat roof window benefits from a special self-cleaning coating on the outer pane.
This helps reduce the accumulation of dirt and significantly reduces the amount of manual cleaning required.
The RoofLITE+ FRF B600 is manufactured from internally insulated white PVC, providing excellent durability and thermal performance.
PVC is also naturally moisture resistant and easy to maintain, making the window suitable for heated rooms where higher humidity levels may occur.
The smooth white internal finish complements modern interiors and requires minimal maintenance.
The RoofLITE+ FRF B600 is designed to provide excellent energy efficiency when installed as part of the complete flat roof window system.
Reference thermal performance:
This high level of insulation helps reduce heat loss through the roof and contributes to a more comfortable indoor environment throughout the year.
The RoofLITE+ FRF B600 can be installed on roofs with pitches between 5° and 15°, making it ideal for many 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 help simplify the fitting process.
