Sheerline has launched the S1 roof lantern with a number of security innovations. Overlapping cast end caps prevent the bar and top caps from being removed and anti-tamper screws to attach end caps to roof bars. Two and four way top caps are also bolted through from the inside, preventing easy removal. The arrangement of the interlocking eaves beam means that the glass cannot be removed from the outside and features a unique patent pending glass lock, lowering the risk of break-ins even further.
The S1 roof lantern is designed with the same Thermlock multi-chambered thermal breaks as the Classic and Prestige systems. Cold bridging is prevented by ensuring the aluminium is fully encapsulated below the glass line with a co-extruded perimeter seal creating a weathertight seal for enhanced performance and energy efficiency.
50mm rafter, hip and ridge sightlines maximise light. Rafter and hip top caps sit just 8mm above the glazing level on the exterior. Completing this refined architectural appearance, corner and rafter end caps run perfectly in line with its perimeter.
Garnalex CEO Roger Hartshorn said: “We expect the S1 roof lantern to transform the aluminium roof lantern market, much like Classic and Prestige have done for aluminium windows and doors. Not only is it beautiful, but it also tackles some of the security issues that customers face with existing products. Our team of experts have reinvented aluminium roof lanterns into something that is ultra-secure and thermally efficient as well as being stylish and contemporary. The latest addition to the Sheerline family is fabricator friendly and offers easy, trouble-free installation. And it’s available on short, reliable lead times.”
The S1 is available in three stocked colours across 10 styles, with two and four-way options and designed around 28mm glazing.
