About Us
The UK’s most secure lantern, keeps you and your home safe
The innovative construction of the S1 system eliminates the security weaknesses of traditional lantern designs. Features such as anti-tamper screws, enclosed anti-tamper glazing, security tape and our patent pending glass lock, alongside our unique high security ridge end, ensure there isn’t an easy way to enter your property via your flat roof lantern. All of these innovative features combine to make Sheerline’s S1 system the UK’s most secure aluminium lantern roof*. A laminate glass upgrade is also available for extra security if required. So if you are looking for a lantern that comes with extra peace of mind as standard – then we have you covered.
*Mainstream residential roof lantern - not utilising bonded glass.
Whatever the weather Thermlock® technology helps keep you comfortable and heating bills lower
The S1 lantern combines aluminium’s clean lines with exceptional thermal performance and features our innovative Thermlock® multi-chamber technology to keep you and your property 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, far superior to traditional polyamide systems based around 24mm glazing. A unique co-extruded perimeter seal also ensures draughts and rain are kept safely outside. 28mm glazing also allows acoustic dampening glass to be fitted if required.
28mm glazing 1.0 U-value W/(m²K)*
Thermal transmittance, also known as a U-value, measures the rate of transfer of heat. The better-insulated a window is, the lower the U-value will be. *Centre pane U-value. Subject to glass specification.
With great looks from every angle – due to our unique ultra low line aesthetics
Slim, consistent 50mm rafter, hip and ridge sightlines maximise the light flooding into your home, creating bright, airy interiors and banishing gloom. The S1 lantern also 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 of the lantern, so no unsightly angles jut out to spoil the perfect lines of this outstandingly beautiful high-performance aluminium lantern. Leaving you with the ideal balance of understated refinement, contemporary looks and exacting quality standards.
