SECURE, SUSTAINABLE AND STYLISH – THE SHEERLINE S1 ROOF LANTERN

Designed to be easy to manufacture and fit, Sheerline’s S1 Roof Lantern delivers truly modern aesthetics coupled to highly efficient thermal performance, and heightened security. Resulting in a roof lantern that stands head and shoulders above the competition and raises standards in the sector.

Made in Britain and manufactured at our energy-efficient aluminium extrusion facility, the S1 Lantern is supplied on short lead-times, letting customers react quickly to customer demand and convert more enquiries into sales. Styled to co-ordinate with the rest of the Sheerline range of windows, doors, and bi-folds, S1 is the perfect finishing touch for modern kitchen/diner extensions.

STYLISHLY DIFFERENT

Meticulous care was taken during the design process to create a product that offered clean and ultra-low sightlines with a contemporary appearance to set it apart from the competition. Rafter, hip, and ridge beams are designed with consistent 50mm sightlines, creating the refined proportions homeowners are looking for, while also maximising the amount of light flooding into interiors.

Corner and rafter cappings run perfectly in line with the perimeter, creating a sleek, almost seamless exterior aesthetic that gives the product a uniquely ‘architectural’ look. While top caps sit just 8mm above the glazing, accentuating the clean and understated look by visually blending in the glass and rafters.

The S1 is available in ten style variations, from pyramids to jack rafter designs that accommodate spans up to 3.2 x 6m and comes stocked in three standard colours: Pure White, Anthracite Grey or Jet Black, with other bespoke single or dual sided RAL colours available to special order.

SUSTAINABLE INNOVATION

Sheerline’s unique Thermlock® technology sits at the heart of all our products, designed to reduce levels of cold bridging and provide excellent thermal performance. Thermlock® offers improved performance over the polyamide used in other systems as it integrates a closed-cell, multi-chamber construction. As we manufacture it on site, supply is also far more reliable and not prone to the chronic supply issues polyamide has recently experienced.

This assembly considerably reduces U-value across the whole roof lantern and using 28mm glazing enables laminated or acoustic IGU’s to be specified without hampering thermal efficiency. S1 provides a centre pane U-value of 1.0W/(m2K), and we’ve totally eliminated any aluminium bridging from the interior to the exterior, so there are no cold spots, helping eliminate condensation issues.

Co-extruded perimeter seals on the eaves beam provides excellent watertightness and protection against air and wind ingress, with attention being paid to ensure water is prevented from travelling back up and around glass units. Fully compliant with weather performance standards, the S1 can withstand snow loads of up to 1.2KN/m, covering the whole of the UK up to 200m altitudes.

SECURITY INNOVATION

In the absence of any formal security standards, there has been little attention paid to developing a truly secure roof lantern. However, the Sheerline S1 seeks to rectify that, bringing together unique design innovations to provide the industry with the most secure ‘non-bonded’ mainstream roof lantern on the market.

Firstly, a unique glass lock incorporated into the end of the eaves beam locks in glass units securely, with high-performance glazing tape adding an extra layer of security. Anti-tamper screws are used externally across the entire roof lantern, helping keep the roof eaves, all adjoining rafters, hips, and corner end caps secure. Two- or four-way crown top caps are also fixed internally using strong metal M8 screw to prevent unwanted access from intruders.

ATTENTION TO DETAIL

The S1 Roof Lantern also uses Sheerline’s unique patented corner jointing method, reducing misalignment during installation. These unique corner connectors cleverly pull together mitred corners, providing a strong eaves beam to assemble the rest of the roof from.

For protection during fitting rafter beams are fitted with internal end caps, helping to eliminate any scuff marks as they are positioned, preventing damage and ensuring a trouble-free installation.

Finally, a shallow channel has been incorporated in the eaves beam and ridge to allow LED lighting strips to be installed, bringing a personal and individual feel to the inside of the roof lantern.

CUSTOMER TESTIMONIAL

Titan Aluminium, based in Hampshire was an early adopter of the S1 system and John Jones, Managing Director, comments:  ‘We supply shatterproof, flat glass roofing systems alongside roof lanterns and aim to offer the very best options in both to our customers. We were excited when we learnt about the S1 lantern as it was obvious it was designed to overcome many of the issues we’d encountered with traditional lanterns in the past.

Sheerline’s products fall perfectly in line with our own manufacturing and installation standards and we received outstanding support from the Sheerline sales and technical teams from day-one, with one-to-one guidance and training when needed alongside a full catalogue of marketing material to help us lead customers through the buying process.

S1 has gone down extremely well with our customer network, their installers, and ultimately the homeowner, who instantly recognise what the product has to offer. Discreet and slim stylish aesthetics, exceptional thermal performance, and fantastic high levels of security are just some of the benefits that allow us to present a very attractive proposition to customers.’
