Sheerline launches S3 Architectural glazed roof

After successfully previewing the S3 Architectural glazed roof at FIT Show 2025, Sheerline has announced it is now available to order. In addition, it is on permanent display at the National Self Build & Renovation Centre (NSBRC) in Swindon.

Sharing a similar design ethos to the award-winning S1 Roof Lantern, the S3 has been developed from the ground up and according to Sheerline combines a refined sleek aesthetic with performance and ease of installation.

For example, there are fewer components required for the S3 when compared to traditional ‘lean-to’ systems, which is a benefit to installers as it simplifies on-site assembly. Plus, the pitch is set in the factory during fabrication, which reduces the time required on site.

A standout feature that gained attention during FIT Show 2025 was the gutter and downpipe system, which are fully aluminium so there’s no warping or fading over time. The S3 on the stand featured the contemporary square gutter, but there’s also a traditional Ogee option too.

The S3 also suites with Sheerline’s existing range of aluminium windows and doors and is compatible with the SheerVent intelligent ventilation solution that utilises powered actuators and can be enhanced with a discreet rain sensor.

In addition, to ensure the highest possible thermal efficiency, Sheerline says that the S3’s rafter bars are 230% better insulated when compared to traditional conservatory roofs, thanks to Thermlock technology.

Jon Crohill, Sheerline’s technical and design office manager, said: “In typical Sheerline fashion, we’ve spent a lot of time working on the detail, ensuring that this premium product sits perfectly alongside our existing range.

“Designed from the ground up, the S3 is aimed at those consumers who want to transform their homes. But it’s not about simply adding space, it’s about extending the luxurious setting they have already created within their home,” he added.
