Korniche Aluminium Flat Glass Rooflights

Advanced Weather Protection

Engineered to maximise unobstructed views of the sky. When viewed from the room below, the structural frame is designed to sit entirely hidden beneath the standard internal plaster line, creating a striking, frameless "open sky" look that expands the feel of the room.

For the trade, it represents the ultimate fit-and-forget solution. Delivered as a factory-prepared, fully configured kit, its intelligent design eliminates complex measuring, on-site adjustments, or messy adhesive applications, allowing installers to secure a perfect drop-in fit in record time.

Smarter Engineering

Supply-only Korniche Flat Glass rooflights. Features minimalist frameless internal sightlines, excellent weather protection, and factory pre-assembled installation tech.

Built to comfortably exceed modern UK Building Regulations (Document L compliance). The robust frame features an advanced polyamide multi-chamber thermal break paired with high-performance insulating gaskets. This completely eliminates cold-bridging, ensuring excellent heat retention during freezing winters while keeping extensions cool in summer.

Every unit features a microscopic self-cleaning surface coating as standard, using rainwater and UV rays to break down and cleanly wash away organic dirt. Externally, an elegant gloss black ceramic edge border beautifully conceals structural sealant lines for a refined, premium finish.

What is a U-Value?

This measures how effectively a glass unit prevents indoor heat from escaping. The lower the U-value number, the better insulated the property will be, keeping heating costs down during cold British winters.

What is Solar Heat Reflection?

The percentage of the sun's infrared heat energy that is bounced away before it can enter the room. Choosing a high percentage prevents the uncomfortable "greenhouse effect" during hot summer months.

What is Light Transmission?
The percentage of visible natural light that passes completely through the glazing. Higher numbers translate to a brighter, more naturally illuminated living area.
