3m x 4.5m Made to Measure Flat Roof Glass Rooflight

Create a spectacular feature above a kitchen, dining area or open-plan living space with our 3m x 4.5m Made to Measure Flat Roof Glass Rooflight.

Manufactured to order in Bristol, this large rooflight is particularly suited to new flat roof extensions and orangery-style extensions, where a substantial area of overhead glazing can bring natural daylight deep into the room below.

With a maximum internal frame size of approximately 3000mm x 4500mm, this model can create up to approximately 13.5m² of internal rooflight area, making it an impressive architectural feature for larger residential and commercial projects.

Large Glass Rooflight for Kitchen Extensions

Modern kitchen extensions often combine a large open-plan layout with bi-fold, sliding or French doors overlooking the garden. While these provide plenty of light around the perimeter, a large glass rooflight can introduce daylight directly into the centre of the extension.

Positioned above a kitchen island, dining table or central seating area, a 3m x 4.5m rooflight can become one of the main architectural features of the new room.

Ideal for Orangeries and Large Flat Roof Extensions

This larger rooflight is particularly suitable for:

• Large kitchen extensions
• Kitchen and dining extensions
• Orangery-style extensions
• Open-plan living spaces
• Rooflights above kitchen islands
• Rooflights above dining areas
• Large family rooms
• Garden rooms
• New-build properties
• Selected commercial buildings

Up to 13.5m² of Rooflight Area

At the maximum internal dimensions of 3000mm x 4500mm, the rooflight provides approximately 13.5 square metres of internal rooflight area.

This substantial glazed area makes it possible to introduce a significant amount of natural daylight into larger extensions while creating a striking feature when viewed from inside the property.

Made-to-Measure Flat Roof Rooflight

Every rooflight is manufactured to order, so you are not restricted to the maximum 3m x 4.5m dimensions. The system can be manufactured to the dimensions required for your individual project within the available size range.

• Maximum Internal Frame Size: Approximately 3000mm x 4500mm
• Maximum Internal Area: Approximately 13.5m²
• Application: Flat Roofs
• Manufacture: Made to Measure
• Standard Glazing: Low-E Toughened Argon-Filled Glass
• Double & Triple Glazing: Available
• Manufactured: Bristol

Important Rooflight Measuring Information

The dimensions entered when ordering are the internal frame dimensions.

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

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

3000mm x 4500mm Rooflight Size Example

• Internal Frame: 3000mm x 4500mm
• Approx. External Frame: 3140mm x 4640mm

If the optional welded cill is selected, allow approximately 320mm additional overall when calculating the finished dimensions.

Please confirm all measurements before ordering and before constructing the roof opening, kerb or supporting structure.

Low-E Toughened Argon-Filled Glass

The standard rooflight is supplied with Low-E toughened, argon-filled glazing, combining safety, natural daylight and good thermal performance.

With a rooflight of this scale, choosing an appropriate glazing specification is particularly important because the glazed roof becomes a substantial part of the extension.

Double or Triple Glazing

A range of glazing specifications is available depending on the requirements of your project:

• 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, self-cleaning glass can be a particularly useful upgrade because access to the external glazing for routine cleaning may be difficult.

This makes it a popular consideration for larger kitchen extensions, dining rooms and orangery-style installations.

Blue Tint Glass Option

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

Multi-Panel Roof Glazing System

A large 3m x 4.5m rooflight is constructed using multiple individual glass units supported by a strong roof glazing bar system.

The glazing bars provide support between the glass sections and allow a substantial glazed roof feature to be created across a much larger area than would be practical with a single pane of glass.

Choice of Rooflight Colours

Choose from a selection of profile and roof bar finishes:

• 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 to provide rainwater collection around the rooflight where required.

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

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

Optional Cresting and Finials

For a traditional orangery-style rooflight, decorative cresting and finials can be added.

Alternatively, these can be omitted where a cleaner contemporary appearance is preferred for a modern extension.

Flat-Packed or Part-Assembled

Select the assembly option most appropriate for your project:

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

Delivery and Unloading

A rooflight approaching 3m x 4.5m is a substantial made-to-measure product. Suitable vehicle access and sufficient assistance for unloading must therefore be considered before delivery.

The individual glass units and roof components should be handled and stored carefully on site until installation.
