The new Korniche Roof Lantern from trade-supplier Made For Trade represents a major step forward for aluminium roof lanterns — and is a strong option for installers and homeowners working with Martindale windows. Described as “stronger, warmer, slimmer and faster to install than ever before,” it is built to meet both aesthetic and performance expectations.

Here’s what makes it stand out — and how it fits into a Martindale windows project.

Key Features & Benefits

1. Engineered for trade, built for speed

  • It’s billed as the “fastest-to-fit aluminium roof lantern on the market,” thanks to fewer components and pre-assembled elements.
  • No on-site cutting or messy silicone required — the base-seal injection system keeps things cleaner and quicker.
  • Ideal for installers working on extensions, conversions or replacement roof lanterns where speed and precision matter.

2. Slimmer profiles, larger glass spans

  • The structural redesign supports wider glass spans with narrower frame components — giving more daylight, less visual interruption.
  • For homeowners this means the lantern becomes more of a transparent ceiling element rather than a bulky frame.
  • Excellent for high-end aesthetics that match well with premium Martindale windows.

3. Enhanced thermal performance & weather resistance

  • Advanced polymer thermal breaks, insulated joints, argon-filled units and a warm-edge spacer help reduce heat loss.
  • It is designed to exceed current Building Regulations standards.
  • Gasket systems, pre-tensioning and other structural refinements improve both strength and weather-proofing.

4. Bespoke and flexible finishes

  • Multiple configurations: pyramid or rectangular lanterns, a range of sizes up to 6 m × 4 m external.
  • Colour options: Matt Black, Gloss White, Matt Grey as standard; dual-colour and full bespoke RAL/BS finishes available.
  • Glazing options: self-cleaning, solar-control, laminated/privacy glass.
  • Optional fully integrated dimmable LED lighting and flush-fit diffuser for night-time ambience.

5. Low maintenance and long term support

  • UK-fabricated, CNC-machined components and precision manufacturing ensure a high-quality finish.
  • Minimal maintenance required when installed according to guidelines.
  • Made For Trade emphasises a 10-year warranty and strong customer service track record. 

Why it pairs well with Martindale windows

If you’re already specifying or using Martindale windows in a project, the new Korniche lantern is a complementary choice for several reasons:

  • High-end aesthetic match: Martindale windows often serve premium builds where detailing, colour choice and finish quality matter. The Korniche lantern’s slim lines, bespoke colour finishes and modern profile align with that level.
  • Thermal performance consistency: Installing a high-performing roof lantern ensures you’re not undermining the insulation or weather-tightness of the rest of the fenestration package.
  • Installation efficiency: Martindale-fenestration installers will appreciate the reduced on-site complexity of the Korniche system. Faster installs reduce labour time and potential site disruption.
  • Customisation: Many Martindale projects involve bespoke sizes, finishes or glazing requirements. The Korniche’s flexibility in size, pitch, colour and glazing is a strong fit.

Key Specification Highlights

  • Lantern sizes up to 6 m × 4 m external.
  • Fixed pitch of 25° for standard models.
  • 28 mm double glazed units as standard.
  • Colour-finish options: three stock RAL/BS, dual-colour at no extra cost, bespoke colours available.
  • Glazing options include self-cleaning glass, solar control coatings, privacy/laminated glass.

Considerations for Specification & Installation

  • Check structural support & up-stand: Larger spans (e.g., up to 6 m width) will impose load requirements; ensure the supporting structure and up-stand comply with spec.
  • Glazing orientation: If the lantern is south-facing with direct sun, solar-control glass may be advisable to reduce solar gain.
  • Colour coordination: Dual-colour finish (e.g., anthracite external, white internal) can tie in with Martindale window frames and internal décor.
  • LED lighting integration: If specifying the integrated lighting option, coordinate with lighting controls and power supply early in the design stage.
  • Maintenance & warranty: Follow the manufacturer’s installation guidelines carefully to maintain the warranty and ensure optimum performance.
  • Compatibility: Though the lantern is described generically, ensure that if you’re combining with Martindale windows, the details (flashing, interface, roof junctions) are properly specified so all elements work together seamlessly.

Conclusion

The new Korniche Roof Lantern from Made For Trade is a compelling upgrade for anyone specifying or installing premium aluminium fenestration like Martindale windows. With its refined appearance, improved thermal performance, installation efficiency and customisation options, it offers a modern solution for rooms where you want daylight, style and performance in one.

If you’re working on an extension, orangery or renovation project and already using Martindale windows, specifying this lantern could elevate the project’s finish and value.
