The ‘next generation’ S1 roof lantern from Sheerline

Sheerline continues to expand its impressive range of innovative aluminium products with the launch of a next generation aluminium roof lantern. It combines sleek low-level styling and cutting-edge performance to create one of the most secure, thermally efficient and beautiful lanterns on the market.

The S1 roof lantern has been designed from scratch by Garnalex’ expert team, and the end result is ground-breaking. S1 is not only ultra-secure and energy efficient but stylish and modern, compared to clunky traditional systems. Available in three stocked colours across 10 different styles, with two and four-way options and designed around 28mm glazing, this advanced roof lantern has the options to suit any project.

Sheerline’s S1 redefines the product category’s security expectations, often a weak point in lantern roofs, with a number of unique innovations. Overlapping cast end caps prevent the bar and top caps from being removed and anti-tamper screws are provided to attach end caps to roof bars. High-security 2 and 4 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.

Designed with the same innovative Thermlock® multi-chambered thermal breaks as the Classic and Prestige systems, the S1 roof lantern offers maximum thermal performance throughout its design, from the eaves beam and ridge to each rafter assembly. Cold bridging is prevented by ensuring the aluminium is fully encapsulated below the glass line with a unique co-extruded perimeter seal creating a weathertight seal for enhanced performance and energy efficiency.

Slim, consistent 50mm rafter, hip and ridge sightlines maximise light flooding into homes, creating bright, airy interiors and banishing gloom. The S1 lantern also features ultra low line aesthetics, so rafter and hip top caps sit just 8mm above the glazing level on the exterior, creating a sleek modern look. Completing this refined architectural appearance, corner and rafter end caps run perfectly in line with its perimeter, so no unsightly angles jut out to spoil the perfect lines of this beautiful high-performance aluminium lantern. It creates the ideal balance of understated refinement, contemporary looks and exacting quality standards.

Roger Hartshorn, CEO of Garnalex, says: “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.”
