13.75m² Rooflight for Large Flat Roofs

At its maximum dimensions, this rooflight provides approximately 13.75 square metres of internal rooflight area, making it an excellent option where a substantial glazed feature is required.

The combination of a 2.5m width and extended 5.5m length makes this model particularly suitable for introducing daylight along large rooms and commercial spaces.

• Large kitchen extensions
• Open-plan kitchen and dining areas
• Large living spaces
• Garden rooms
• Single-storey extensions
• Commercial buildings
• Offices and workplaces
• Reception areas
• Showrooms
• Retail premises
• Restaurants and hospitality buildings
• Property developments
• New-build projects

Important Rooflight Measuring Information

The dimensions entered when ordering are the internal frame measurements.

The surrounding profiles are approximately 70mm wide, meaning approximately 70mm must be added to each side when calculating the overall external frame dimensions.

The approximate external frame dimensions are therefore 140mm greater than the internal dimensions in each direction.

2500mm x 5500mm Rooflight Size Example

• Internal Frame: 2500mm x 5500mm
• Approx. External Frame: 2640mm x 5640mm

Where optional welded cills are selected, additional allowance must be made when calculating the finished external dimensions.

Please carefully check all dimensions 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, combining safety, natural daylight and good thermal performance.

The Low-E coating is designed to reduce heat transfer through the glazing, while the argon-filled sealed units provide additional insulation.

Double or Triple Glazing

Choose from double or triple glazing depending on the selected rooflight specification.

Available glazing options include:

• Low-E Toughened Glass
• Argon-Filled Sealed Units
• Double Glazing
• Triple Glazing
• Self-Cleaning Glass Upgrade
• Blue Tint Glass Upgrade

Self-Cleaning Glass Option

For a rooflight of this size, the optional self-cleaning glass upgrade can be particularly useful because access to the external surface of the glazing may be difficult.

Self-cleaning glass can help reduce the amount of routine cleaning required, making it a practical upgrade for large residential and commercial rooflights.

Blue Tint Glass Option

Blue tint glass is also available, providing an alternative appearance to standard clear glazing while continuing to introduce natural daylight into the space below.

Strong Multi-Panel Glazing Bar System

A rooflight measuring up to 2.5m x 5.5m requires a substantial supporting structure. The glass roof is divided into individual glazed sections supported by a strong roof glazing bar system.

This provides the structural support required for the individual glass units while allowing a very large overall glazed roof area to be created.

Choice of Rooflight Colours

Select from a range of profile and roof bar finishes to coordinate the rooflight with the surrounding building:

• White
• Rosewood
• Mahogany
• Light Oak

Aluminium roof bars are also available in selected Light Oak, Mahogany and Rosewood finishes.

Optional Hunter Regency Guttering

An optional Hunter Regency guttering system can be supplied where rainwater collection around the rooflight is required.

Depending on the selected configuration, the guttering package can include:

• Hunter Regency guttering
• Downpipes
• Downpipe shoes
• Gutter spigots
• 90° gutter angles
• Traditional gutter brackets

Optional Cresting and Finials

Optional decorative cresting and finials can be added where a more traditional appearance is required.

For contemporary extensions, offices and commercial buildings, these can simply be omitted to retain a cleaner roofline.

Flat-Packed or Part-Assembled Rooflight

Choose the assembly option most appropriate for your project and site access:

• Flat-Packed: Supplied ready for assembly on site.
• Pre-Assembled to Glazing Stage: Main rooflight structure assembled before delivery, with the glass and finishing trims installed on site.

Delivery of Large Glass Rooflights

A 2.5m x 5.5m rooflight is a substantial made-to-measure product, so delivery access and unloading requirements should be considered before ordering.

Please ensure there is suitable access for the delivery vehicle and sufficient assistance available to safely unload and move the rooflight components and glass.
