The UK’s most secure, sustainable and stylish roof lantern
Choosing the right roof lantern for your home is an important decision. They should let in the maximum amount of light, yet keep heat in your home and would be intruders out. Letting you enjoy more natural light and amazing night time views of the stars, while bringing a sense of space and tranquillity to your home. This is why we have designed the S1 aluminium roof lantern from the ground up to meet your every need. Building on years of experience, we’ve incorporated many new innovative ideas to create a warmer, slimmer and much more secure roof lantern. Thermlock® multi-chamber thermal technology helps keep heating bills low, while deep internal bars create an ultra strong structure for spans up to 3.2 x 6m without tie bars. Ultra low line aesthetics give a stylish architectural appearance, enhanced with hardwearing powder coated aluminium inside and out. Security is also built into the heart of every S1 lantern, helping protect you and your home.
Secured by Design Upgrade Option
Sheerline’s award-winning aluminium S1 roof lantern is one of the most secure roof lanterns in the UK and now comes with a Secured by Design (SBD) upgrade option. SBD is a police-backed initiative that identifies products that offer increased levels of security. This optional security upgrade adds an extra layer of defence ensuring that your S1 aluminium roof lantern is secure enough to withstand opportunist criminals, providing extra peace of mind. The optional upgrade adds additional security clamping plates, locking the SBD lantern’s laminated glass panels in place, preventing them from being lifted and removed by would-be intruders* even if rafter top caps have been removed. These stainless steel components are held firmly in place by stainless steel security screws for added strength. This optional security upgrade is invisible on finished roofs and doesn’t compromise the stylish contemporary design or thermal performance that Sheerline is known for. *Based on SBD’s test criteria
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.
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.
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.
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.
Sheerline aluminium roof lanterns are available in a choice of 10 styles from square ‘pyramid’ designs to grander options suitable for larger ‘orangery’ style installations. Maximum sizes range from 2.4 up to an impressive 6m long, all set at a 25˚ pitch and all weather rated for the whole of the UK*. Rated for a snow load of 1.2 KN/m2. Covering the whole of the UK up to 200m altitude.
S1 lanterns also feature an integral LED light channel around the perimeter of the roof – giving you an easy way to add mood lighting and add the final touch of individuality to your interior.
Adding three more styles to the S1 roof lantern, our new 3 Way option allows for bigger spans to be catered for without the need for jack rafters. All with the same sleek aesthetics as our existing 2 and 4 way designs.
For S1 lanterns we are also introducing SheerVent
With a sleek minimalist design that sits perfectly flush with S1’s rafter bars, and using powered actuators that can be intelligently automated, Sheerline has reimagined roof vents, bringing them into the 21st century at last. Dispensing with the need for muntin bars, SheerVent® offers reliable ventilation without the risk of leaks. Fully thermally broken and using the same high-performance glazing as the rest of the S1 roof, SheerVent® is yet another feature that puts the S1 lantern ahead of the competition.
