Please read this notice before relying on information published on EN1366.co.uk.
General guidance only
EN1366.co.uk provides general, plain-English information about fire and smoke ductwork standards. It is intended to help readers identify questions and evidence that may require closer review. It is not a design approval, compliance certificate, product certification or project-specific instruction.
Not an official standards body
EN1366.co.uk is not affiliated with BSI, CEN, UKAS, LPCB or any certification body. The website does not reproduce or replace British or European Standards. Users should obtain the relevant published standards and applicable test, classification, field-of-application and manufacturer documentation.
Project responsibility
Fire and smoke ductwork performance depends on the complete system, including its intended use, classification, materials, dimensions, joints, pressure, orientation, supports, penetrations, fire stopping, protection and installation. Project requirements should be reviewed by appropriately competent parties using current evidence.
Accuracy and updates
Reasonable care is taken when preparing the guidance, but standards, regulations, evidence and industry practice can change. No page should be treated as a substitute for checking the current source documents and project requirements.
Relationship with DuctFix
EN1366.co.uk is linked to DuctFix and may direct visitors to DuctFix for practical ductwork manufacturing enquiries and initial project discussions. Any supply or service is subject to separate project information, review and commercial terms.
