Long Narrow Rooflight for Commercial Buildings
The proportions of the 1m x 5m glass rooflight make it particularly suitable for commercial buildings and other properties containing long internal spaces.
Rather than concentrating daylight into one square area, the extended five-metre design allows glazing to run along a much greater section of the roof.
This can make it an excellent solution for:
- Commercial buildings
- Covered walkways
- Internal corridors
- Office buildings
- Reception areas
- Entrance areas
- Retail premises
- Hospitality buildings
- Large flat roof areas
- Commercial extensions
- Large residential extensions
5 Metre Glass Rooflight for Walkways and Corridors
A long glass rooflight above a walkway or corridor can provide natural overhead daylight along an extended route without requiring an excessively wide roof opening.
With an internal width of up to 1 metre and length of up to 5 metres, this rooflight is particularly well suited to long, narrow spaces where daylight needs to be distributed across a greater distance.
Important 1m x 5m Rooflight Measuring Information
The dimensions entered when ordering are the internal frame measurements. The overall dimensions will be larger once the window profiles and any selected cills are included.
The window profiles are approximately 70mm wide. Allowing approximately 70mm on each side means the external frame measurement is approximately 140mm greater than the internal frame measurement in both directions.
1000mm x 5000mm Rooflight Size Example
A rooflight ordered at the maximum 1000mm x 5000mm internal frame size would have approximate frame dimensions of:
- Internal Frame: 1000mm x 5000mm
- Approx. External Frame: 1140mm x 5140mm
Optional Welded Cill Dimensions
Where a welded cill is selected, the cill extends approximately 160mm from each side of the internal frame measurement.
For the maximum 1000mm x 5000mm internal size, this would give an approximate overall cill dimension of:
- Internal Frame: 1000mm x 5000mm
- Approx. Overall Cill: 1320mm x 5320mm
Please check the internal frame, external frame and cill dimensions carefully before constructing the roof opening, kerb or supporting structure.
Low-E Toughened Glass Rooflight
The standard rooflight is supplied with Low-E toughened, argon-filled glass, providing a combination of natural daylight, safety and thermal performance.
The Low-E coating is designed to reduce heat transfer through the glazing, while the argon-filled sealed units further improve its insulating performance.
Double or Triple Glazing Options
A choice of glazing specifications is available depending on the selected roof configuration.
- Low-E Toughened Glass
- Argon-Filled Sealed Units
- Double Glazing
- Triple Glazing
- Self-Cleaning Glass Upgrade
- Blue Tint Glass Upgrade
Self-Cleaning Glass for Large Rooflights
An optional self-cleaning glass upgrade can be particularly useful with a rooflight of this size, where routine access to the external surface of the glazing may be difficult.
This makes it a practical option for commercial buildings, covered walkways and large flat roof installations.
Blue Tint Glass Option
Blue tint glass is also available for projects where an alternative glazing appearance is preferred.
Select your required glazing specification when configuring the made-to-measure rooflight.
Strong Roof Glazing Bar System
The rooflight uses a robust roof glazing bar system designed to securely support the glazing and create a durable, weather-resistant finished roof structure.
The system provides the support required for the selected glazing while allowing the rooflight to be manufactured specifically for the dimensions of the individual project.
Choice of Rooflight Frame Colours
Choose from a selection of profile and roof bar finishes to suit the surrounding building:
- White
- Rosewood
- Mahogany
- Light Oak
Aluminium roof bars are also available in selected finishes including Light Oak, Mahogany and Rosewood.
Optional Hunter Regency Guttering
An optional Hunter Regency guttering package can be supplied to provide rainwater management around the rooflight.
Depending on the selected configuration, the package can include guttering, downpipes, spigots, brackets and appropriate gutter angles.
Optional Cresting and Finials
Decorative cresting and finials can be added where a more traditional or decorative appearance is required.
These options allow the finished appearance of the rooflight to be adapted to suit different residential and commercial projects.
Flat-Packed or Part-Assembled Rooflight
Choose the assembly option most appropriate for your project:
- Flat-Packed: Supplied ready for assembly on site.
- Pre-Assembled to Glazing Stage: Main structure assembled before delivery, with the glass and finishing trims installed on site.
Please consider access and unloading requirements carefully when selecting the pre-assembled option. A rooflight of this length can require several people and suitable handling arrangements depending on the final configuration.
5 Metre Glass Rooflight for Large Flat Roofs
With an internal length of up to 5 metres, this rooflight creates an impressive strip of overhead glazing capable of introducing daylight along a substantial section of a building.
The 1000mm x 5000mm glass rooflight is particularly useful where the building design or available roof area favours a long rectangular rooflight rather than a conventional square design.
For residential projects, the long format can also work well above extended kitchen areas, large kitchen islands, dining areas and open-plan extensions.

Because every rooflight is manufactured specifically for your order, please carefully check all dimensions and configuration options before ordering and before constructing the supporting roof opening or kerb.

Roof felt, flashing and surrounding weatherproofing must be correctly completed as part of the installation.
The rooflight must be properly integrated with the supporting structure and surrounding flat roof system to provide a secure and weather-resistant finished installation.
