Why choose S1 Roof Lantern...

Secure, sustainable, stylish, and thermally efficient aluminium roof lanterns. Thermally efficient, structurally safe and secure and installer friendly, our S1 roof lanterns are built on innovation with slim sightlines and maximum light. S1 features ultra low line aesthetics so rafter and hip top caps sit close to the glazing level on the exterior, creating a sleek modern look. Completing this refined architectural appearance our corner and rafter end caps run perfectly in line with the perimeter, so no unsightly angles jut out to spoil the perfect lines of this contemporary high-performance aluminium lantern.

​

Exceptional thermal performance and features our innovative Thermlock® multi-chamber technology to keep properties well insulated against the worst of the UK weather. This coupled to high performance 28mm glazing means our lantern roofs offer class leading thermal performance.

Available in 13 styles up to 3.2m x 6m without tie bars, and automation vent options are also available.
