Sheerline Launches S3 Architectural Glazed Roof

After successfully previewing the S3 Architectural Glazed Roof at FIT Show 2025, Sheerline is pleased to announce 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 is set to shake up the glazed roof market. Aside from the launch of the S2 (an evolution of the well-known K2 system) at FIT Show 2023, it is fair to say there has been little innovation in the glazed roof market, until now.

The S3 has been developed from the ground up and reflects the needs and wants, not only of homeowners, but of fabricators and installers too. As with all Sheerline products, it 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.

Homeowners will appreciate the sleek aesthetic of the S3 as it perfectly matches with Sheerline’s aluminium windows and doors, creating beautiful fully glazed extensions for the ultimate in luxurious living.

Aside from the aesthetic appeal, there are other benefits for homeowners including thermal efficiency. Sheerline recognises that while this is important to those in the industry, it is even more important for homeowners who live with the products.

And not just in terms of keeping heat in during winter but also letting heat out during the summer to prevent overheating. Sheerline has the ideal solution for these concerns in the form of SheerVent®. This intelligent ventilation solution utilises powered actuators and can be enhanced with a discreet rain sensor.

In addition, to ensure the highest possible thermal efficiency, the S3’s rafter bars are 230% better insulated when compared to traditional conservatory roofs. This is thanks to the inclusion of Sheerline’s award-winning 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.
