The Brett Martin Contemporary 4-Pane Glass Roof Lantern is a double glazed aluminium roof lantern designed to introduce natural daylight into flat roof extensions and modern living spaces. The 4-pane layout uses fewer glazing bars, allowing larger glass panels and wider views of the sky.
This roof lantern is commonly installed above kitchens, dining areas, and open plan living rooms where a bright central roof feature is required. The thermally broken aluminium frame and Low-E double glazing help reduce heat loss while maintaining high daylight transmission.
Roof Lantern Size Options
The 4-pane roof lantern is available in a wide range of standard sizes designed to suit common flat roof openings.
Lengths mm: 1500 to 3000
Widths mm: 1000 to 2000
These sizes are available in multiple combinations such as:
1500 × 1000
1800 × 1200
2000 × 1500
2500 × 1500
3000 × 2000
Smaller lanterns are often used above compact kitchen extensions or dining spaces where a focused area of daylight is required.
Medium sizes are commonly installed in standard rear extensions where balanced daylight is needed across the room.
Larger lanterns are used in wide open plan areas where a larger glazed roof feature helps distribute daylight across the entire space.
All sizes are based on external upstand dimensions, and bespoke sizes are also available where a project requires a non standard opening.
Frame Construction
The roof lantern uses a thermally broken aluminium frame designed for flat roof glazing.
Aluminium provides strong structural support while allowing slim profiles that maximise the glass area. The thermal break within the frame helps reduce heat transfer between the interior and exterior.
The frame is powder coated to provide long term resistance to weather exposure.
Frame Colour Options
Several internal and external colour combinations are available to match different building styles.
White inside / White outside – RAL 9010 - Used where a consistent white finish is required inside and outside the property.
White inside / Anthracite grey outside – RAL 9010 / RAL 7016 - Used where a lighter interior finish is preferred with darker external window frames.
Anthracite grey inside / Anthracite grey outside – RAL 7016 - Used in contemporary extensions where darker frames are used throughout.
Black inside / Black outside – RAL 9005 - Used where a darker internal and external frame colour is preferred.
White inside / Black outside – RAL 9010 / RAL 9005 - Used where a neutral interior finish is required with a darker exterior appearance.
Glass Specification Options
The lantern is supplied with Low-E insulated double glazed glass units designed for overhead glazing.
Each glass unit includes:
- 4mm toughened outer glass
- Argon filled cavity
- Toughened inner pane as standard
The toughened outer pane provides durability and weather resistance.
A laminated inner pane option is also available.
1. Toughened inner pane – Used for standard installations where toughened safety glass is suitable.
2. Laminated inner pane – Used where additional overhead protection is required. The laminated layer helps hold the glass together if damaged.
Glazing Tint Options
Different glazing tints are available to control light levels and solar heat.
1. Clear self-cleaning glass – Used where maximum daylight transmission is required.
2. Blue solar control self-cleaning glass – Used where reduced solar heat gain and glare are required, particularly in south facing extensions.
The self-clean coating helps rainwater remove surface dirt from the glass, reducing maintenance.
Installation
The roof lantern is designed for installation onto a prepared builders upstand on flat or low pitch roofs. This installation method is commonly used on new extensions and refurbishment projects where increased daylight is required in the room below.
