The Final Touch for Your Extension

A Korniche Roof Lantern isn’t just functional—it’s the stunning centerpiece that completes your flat-roof extension with elegance and precision.

Superior Thermal Efficiency

Thermally Broken Eaves Beam
The foundation of our roof lantern’s energy efficiency starts at the base. The eaves beam features a full thermal break, creating an insulated barrier between aluminum sections to minimize heat transfer.

Innovative Insulating T-Bar
Our exclusive high-performance T-bar bridges the gap between profiles and aluminum finishing caps, delivering the largest possible thermal break for maximum insulation.

Premium Glazing Options

Choose from a selection of high-performance self-cleaning glass options to match your style and needs. With U-values ranging from 1.0 to 1.2, our glazing ensures exceptional thermal efficiency without compromising on clarity or aesthetics.

Unmatched Strength & Stability

Engineered for resilience, the Korniche Roof Lantern offers unparalleled structural integrity while maintaining a sleek, minimalist design.

• Supports extreme loads—a 6m x 4m unit can bear over 8 tonnes.

• Optimized framework ensures maximum glass area with minimal rafters, providing unobstructed views and abundant natural light.

Ultimate Weather & Security Protection

Advanced Weatherproofing
Built to withstand the harshest conditions, our roof lantern uses premium seals and gaskets throughout, guaranteeing a watertight and draught-proof finish.

Tamper-Proof Security
