FAQs

What is the Stratus Lantern Roof?

The Stratus Lantern Roof is a high-performance aluminium roof lantern system engineered to maximise natural light while delivering sleek, contemporary styling, outstanding thermal efficiency, and exceptional structural integrity.

Perfect for kitchen-diner extensions, orangeries, flat-roof extensions, and renovation projects, it creates bright, open spaces that feel larger, lighter, and more inviting—while maintaining impressive energy performance all year round.

Stratus Lanterns are available in a range of configurations to suit different layouts and architectural styles, including 2-way, 3-way, 4-way, and a sleek Contemporary design.

Maximum external dimensions (measured to the external face of the timber upstand/kerb) are as follows:

  • 2-Way: up to approximately 1500mm × 6000mm

  • 3-Way: up to approximately 3000mm × 6000mm

  • 4-Way: up to approximately 2000mm × 2000mm

  • Contemporary Style: up to approximately 1500mm × 3000mm

These versatile sizing options allow the Stratus Lantern Roof system to accommodate everything from compact extensions to expansive open-plan spaces, ensuring the perfect balance of light, proportion, and structural performance.

The Stratus Lantern Roof is engineered for outstanding thermal performance as standard.

It features 24mm high-performance glazing, combined with a fully thermally broken aluminium frame. This means the inner and outer aluminium profiles are separated by a low-conductivity barrier, significantly reducing heat transfer and improving overall energy efficiency.

Compared to conventional aluminium roof lantern systems, Stratus can be up to approximately 65% more thermally efficient, helping to lower energy consumption while maintaining a comfortable indoor environment year-round.

Building Regulations Guidance

  • In most cases, glazing with a U-value of 1.2 W/m²K or better will meet requirements for typical lantern sizes.

  • For lanterns with a projection under 0.6m, glazing with a U-value of approximately 1.0 W/m²K may be required.

This combination of advanced glazing and thermally broken framing ensures the Stratus Lantern Roof not only delivers exceptional aesthetics but also meets modern performance and compliance standards.

Stratus Lantern Roofs are finished with high-quality, powder-coated aluminium external cappings, ensuring long-lasting durability and a refined appearance. They are available in standard colours—White, Grey, and Black—or can be specified in any bespoke RAL colour to seamlessly coordinate with existing windows, doors, or overall project styling.

Internally, cappings can be supplied in either aluminium or uPVC, depending on the chosen specification, allowing flexibility in both performance and interior finish.

Yes—Stratus Lantern Roofs can be specified with integrated roof vents, subject to minimum lantern dimensions. For vented configurations, the minimum size is approximately 500 mm × 500 mm, ensuring proper functionality and airflow while maintaining the roof’s structural integrity and aesthetic appeal.

Yes—Stratus was designed with installers in mind. Its fixed 20° pitch, minimalist frame featuring a slim ridge and discreet rafters, and purpose-engineered components all contribute to a smooth, efficient installation. The result is a clean, professional finish that highlights the roof’s refined architectural design.

Key Advantages of the Stratus Lantern Roof:

  • Enhanced thermal efficiency: Superior insulation reduces heat loss and improves energy performance.

  • Sleek, modern design: Slim ridge and discreet rafters create a clean, minimalist architectural look.

  • Maximum natural light: Large glazed areas and minimal framework flood interiors with daylight.

  • Fully customisable: Choose size, configuration, and colour to suit any extension or orangery design.

  • Durable and weather-resistant: Robust aluminium frame built to withstand the UK climate for long-lasting performance.

To install a Stratus Lantern Roof, you’ll need a timber or suitable upstand/kerb prepared for the lantern to sit on. All ordering measurements should be taken from the external face of the upstand, including any waterproof membrane.

The system is designed around fixed rafter spacing (maximum 1500 mm) and a fixed 20° pitch, so planning should accommodate these specifications to ensure a perfect fit and optimal performance.

Yes—while frequently specified for residential extensions and orangeries, Stratus Lantern Roofs are equally suitable for both domestic and commercial projects, wherever a premium aluminium lantern roof with exceptional performance and aesthetics is required.

Stratus Lantern Roofs offer competitive pricing and relatively short lead times—typically around 5 working days for standard configurations, depending on specifications. For bespoke projects, a wide range of options is available, including custom RAL colours, mixed internal/external finishes, and various lantern configurations to perfectly suit your design requirements.
