The UK's most secure aluminium lantern roof

The Sheerline S1 roof lantern has been designed to eliminate the security weaknesses associated with traditional lantern designs, and features anti-tamper screws, anti-tamper glazing, security tape and a pending glass block, as well as a high security ridge end to ensure there is no easy way to enter a property through the lantern roof. A laminated glass upgrade is also available for additional security.
