Roof Lantern FAQs

What is ‘self-cleaning’ glass?

Self-cleaning glass integrates both solar control and self-cleaning features, making it a top choice for homeowners seeking the pinnacle in glass technology. The special coating on the glass not only decomposes organic grime but also minimises the stickiness of inorganic particles. Water forms a sheet on the surface, sweeping away the loosened dirt as it flows off. The outcome is strikingly effective, leading to visibly cleaner glass.

Like all metals, aluminium conducts heat. Without thermal breaks in our profiles, the warmth inside would be siphoned off to the colder exterior. We circumvent this ‘thermal bridge’ by integrating polyamide sections between the interior and exterior parts of the profile. Polyamide, a glass-filled plastic, serves as an insulator, effectively preventing almost any heat conduction through it.

Korniche roof lanterns are designed for straightforward installation and can be installed without a specialist tradesperson. They do not require any specialised tools and the components are engineered to be incredibly user-friendly.
