Specification
The Sheerline S1 roof lantern is engineered for strength, performance, and streamlined installation, making it an ideal solution for modern flat roof projects.
Performance
The Sheerline S1 roof lantern is engineered to deliver industry-leading performance, combining advanced thermal efficiency with enhanced security and long-term reliability.
The Sheerline S1 roof lantern is designed with security at its core, eliminating common weak points found in traditional roof lantern systems.
A combination of anti-tamper screws, fully enclosed glazing, security tape, and a high-security ridge system creates a robust barrier against intrusion. For projects requiring enhanced protection, an optional Secured by Design (SBD) upgrade provides additional reinforcement, making it a strong selling point for security-conscious homeowners.
Built around innovative Thermlock® multi-chamber technology, the S1 roof lantern delivers exceptional insulation performance. Combined with high-performance 28mm glazing and a co-extruded perimeter seal, it helps retain heat while protecting against the elements.
For homeowners, this means improved comfort, reduced heat loss, and greater energy efficiency, making it ideal for modern extensions and living spaces.
