The innovative construction of the S1 system eliminates the security weaknesses of traditional lantern designs.
Features such as anti-tamper screws, enclosed anti-tamper glazing, security tape and our patent pending glass lock, alongside our unique high security ridge end, ensure there isn’t an easy way to enter your property via your flat roof lantern.
All of these innovative features combine to make Sheerline’s S1 system the UK’s most secure non-bonded aluminium lantern roof.
The UK’s most secure lantern, keeps you and your home safe.

Pair with the Flat Roof System
The Flat Roof System is a lightweight, off-site constructed solution that speeds up installation without compromising on quality. Designed to work effortlessly with S1 Lanterns, Flat Roof Lights, or as a standalone extension roof, it offers exceptional strength through engineered timber ‘I’ beams and warm roof construction. Pre-assembled cassettes, colour-coded parts, and easy-to-handle delivery pods minimise time on site, while bespoke structural calculations ensure complete compliance and confidence.
