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.
