Sheerline Product Guarantee
Posted on 23/04/2026
The Sheerline Product Guarantee from Sheerline Bespoke provides clear, long-term cover across its aluminium roofing and glazing systems, giving fabricators and installers a practical tool to build trust during the sales process.
The guarantee is focused on manufactured aluminium components, covering performance, durability and finish quality across the full product range, including roof lanterns, conservatory roofs and bespoke frames.
Key coverage includes 25 years on powder-coated finishes and aluminium profile integrity, alongside 10 years on laminated foils and gaskets. This ensures long-term protection against issues such as structural degradation, loss of finish quality and weather sealing failure.
Thermal performance is also supported through the durability of Thermlock® thermal break technology, which is designed to maintain insulation performance over time and reduce the risk of cold bridging within the system.
The guarantee is clearly defined to avoid ambiguity. It applies to Sheerline-manufactured components only, excluding installation, fabrication and third-party elements such as glazing or hardware. In the event of a valid claim, coverage is limited to the replacement of the affected components.
For installers, this clarity is important. It allows them to explain coverage confidently, set realistic expectations with homeowners and reduce the risk of disputes after installation.
From a commercial perspective, the guarantee supports sales by addressing key homeowner concerns around longevity, reliability and maintenance, particularly when investing in high-value glazing or extension projects.
In practical terms, the Sheerline Product Guarantee provides a straightforward, transparent level of protection, helping installers specify aluminium systems with confidence while reinforcing trust at the point of sale.
