Sheerline’s Inline Patio Glides Through Enhanced Security Testing

The image shows Sheerline’s SheerGlide® inline patio door with a banner in the top left corner that says ‘PAS 24 Approved’ reflecting the fact that PAS 24 is offered as standard alongside an optional Secured by Design upgrade.

SheerGlide®, the new inline patio from Sheerline, is now available with an enhanced security upgrade. The patio has achieved PAS 24 accreditation, which is offered as standard on all Sheerline products, however, homeowners can now request a Secured by Design (SBD) upgrade.

The rigorous testing process saw the inline patio subjected to physical security testing, a manual attack to check for weak spots, and mechanical load testing. The aim is to assess the product as a whole while also focusing on specific component parts.

Clever in-built innovations ensure SheerGlide® is secure. This includes TwinLock, which is the first single component interlock, combining both security and thermal efficiency. It’s strong and fully thermally broken, and at 38mm, it maintains the slim aesthetic homeowners expect.

Additionally, it’s non-bonded to make it easier to manufacture, transport, and install. Other security features including the modular ‘quad’ hooklock provided by Ingenious Locks & Hardware. This true PAS 24 lock delivers exceptional levels of reliable security and operation.

Security is a key feature of all Sheerline products, and the new inline patio is no different. Given the poor reputation inline sliders have had in terms of both security and thermal performance, it was key the in-house R&D team overcame these issues.

This doesn’t just reflect homeowner demand or the fact that standards have increased across the industry. It reflects Sheerline’s approach and commitment to having a 100% fully matched range in terms of refined aesthetics, high-performance U-values, and enhanced security, across its windows, doors, and roof-related products.

Ben Hartshorn, Sheerline’s Technical and Design Director, said: “When people see SheerGlide®, they see a stylish sliding patio door. But what they don’t see is the months of development and refinement that went into it. Being able to offer enhanced security as standard alongside an optional upgrade is a testament to our commitment to security.”

“We’re really proud of what we’ve achieved and we’re already working on the next stage of development – watch this space for updates,” he added.

Sheerline hasn’t just renewed its commitment to security and continuous development, but also the goal of making life easier for fabricators and installers. This is why SheerGlide® is available in bar length or as a time-saving kit requiring just three decisions.

In a previous post, it was announced that both Sheerline and Garnalex have achieved EPDs.
