Accreditations
Independently audited. Manufactured to the standard the industry expects.
BSI
Accreditation
British Standards Institution
Our sealed unit production is audited by BSI — the UK's national standards body. That audit is not a certificate you hang on a wall; it's an ongoing programme of surveillance, process controls and testing that keeps us honest year after year.
Manufacturing standard
BS EN 1279
BS EN 1279 is the European standard for insulating glass units. It covers everything from long-term seal performance and gas leakage to moisture penetration and edge-seal integrity — the things that determine whether a unit lasts a decade or fails inside 24 months.
Our quality process
Traceable materials
Every batch of glass, spacer, desiccant and sealant is logged and traceable.
Continuous monitoring
Cavity, gas fill and seal parameters checked continuously through the line.
