Long Glass Rooflight for Large Flat Roofs

At up to 4.5 metres long, this rooflight is designed for projects where a substantial length of overhead glazing is required.

The long format can help distribute natural daylight across larger areas and is particularly useful where conventional windows are unable to provide sufficient light to the centre of the building.

Commercial Glass Rooflight

The size and proportions make this rooflight particularly suitable for commercial flat roof projects as well as larger residential extensions.

Typical applications include:

• Commercial buildings
• Offices and workplaces
• Covered walkways
• Long corridors
• Reception areas
• Showrooms
• Large kitchen extensions
• Open-plan living spaces
• Garden rooms
• New-build projects

Glass Rooflight for Walkways and Corridors

The 1.5m x 4.5m maximum dimensions make this rooflight well suited to long sections of flat roofing above walkways and corridors.

A long rooflight can introduce daylight along the length of the space rather than concentrating it in one area, making this configuration particularly useful for commercial and larger architectural projects.

Large Rooflight for Extensions and Open-Plan Spaces

For residential projects, a rooflight of this size can create an impressive feature within a large kitchen extension or open-plan living area.

It can be positioned above a long kitchen island, dining area or central section of an extension to introduce daylight directly into the main living space.

Important Rooflight Measuring Information

The dimensions entered when ordering are the internal frame measurements.

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

1500mm x 4500mm Rooflight Size Example

• Internal Frame: 1500mm x 4500mm
• Approx. External Frame: 1640mm x 4640mm

Optional Welded Cill Dimensions

Where welded cills are selected, additional allowance must be made for the overall dimensions of the rooflight.

Where the cill extends approximately 160mm from each side of the internal frame measurement, the approximate maximum overall dimensions would be:

• Internal Frame: 1500mm x 4500mm
• Approx. Overall Cill: 1820mm x 4820mm

Please carefully check all measurements 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 natural daylight together with safety and thermal performance.

Low-E glazing helps reduce heat transfer through the glass, while the argon-filled sealed units further improve thermal efficiency.

Double and Triple Glazing Options

Choose the glazing specification required for your project, with double and triple-glazed options available depending on the selected configuration.

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

Self-Cleaning Glass Option

Optional self-cleaning glass is particularly worth considering on larger rooflights where access to the external glazing for routine cleaning may be difficult.

Blue Tint Glass Option

Blue tint glass is also available where an alternative appearance to standard clear roof glazing is preferred.

Durable Roof Glazing Bar System

The rooflight uses a strong roof glazing bar system designed to securely support the glazing and provide a durable finished structure.

The system allows the rooflight to be manufactured to your required dimensions while providing the support necessary for the selected glazing configuration.

Rooflight Frame Colour Options

• 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 is required around the rooflight.

Depending on the selected configuration, the guttering package can include gutter sections, downpipes, downpipe brackets, spigots, gutter angles and the necessary connecting components.

Optional Cresting and Finials

Decorative cresting and finials can be added where a more traditional appearance is required, or omitted for a cleaner contemporary design.

Flat-Packed or Part-Assembled Rooflight

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

Suitable assistance will be required for unloading larger or pre-assembled rooflights. Please consider delivery access, component size and safe handling before ordering.

Ordering Your 1.5m x 4.5m Glass Rooflight

Enter the required internal frame dimensions and select the glazing, frame colour and optional extras required for your project.

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

Installation and Weatherproofing

Roof felt, flashing and surrounding weatherproofing should 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.
