Overview
EN 12236:2002 - "Ventilation for buildings - Ductwork hangers and supports - Requirements for strength" is a CEN standard that specifies strength, construction and application requirements for supports used with sheet‑metal ductwork in ventilation and air‑conditioning systems. It applies to all duct shapes (rectangular, circular, oval) and covers factors such as insulation loads, imposed loads (cleaning/maintenance), vibration isolation and corrosion resistance. The standard explicitly does not address earthquake loads or fire protection requirements.
Key topics and technical requirements
- Scope and function: Defines the principal function of hangers/supports - to provide secure connection to the building and accept ductwork loads without adversely affecting airflow or integrity.
- Load determination: Requires designers to account for duct weight, insulation and cladding, accessories (silencers, dampers), hanger self‑weight, imposed maintenance loads (personnel, ladders), and operating temperature.
- Attachment to structure: Fixings must be compatible with the building material, have defined permissible loads and appropriate corrosion resistance. Fixings shall provide a safety factor of at least 3 against the calculated load.
- Support construction:
- Vertical components: designed with a minimum safety factor of 1.5 related to material yield strength (including additional loads such as insulation or access allowances).
- Horizontal components: must support total calculated loads and limit deflection to 0.4% of the distance between vertical fixings.
- Connections between vertical and horizontal parts: also require a 1.5 safety factor and shall not rely solely on friction devices.
- Duct-to-support connection: Horizontal duct installations commonly rest on bearer supports; where brackets are fixed directly to duct walls or joints, the fixings must meet the same safety requirements as the support structure.
- Support spacing and special cases: Spacing must consider support strength, duct assembly strength and acceptable deflection to prevent leakage or aerodynamic degradation. Equipment (fans, heaters, mixing boxes) should be independently supported. Vibration and thermal movement must be considered individually.
Applications
- Designing and specifying ductwork hangers, brackets and support systems for commercial, institutional and residential ventilation and HVAC projects.
- Producing installation guidance and acceptance criteria for contractors, consultants and facility engineers.
- Verifying that retrofit or maintenance work (insulation additions, access for cleaning) does not compromise support capacity.
Who should use this standard
- MEP engineers and HVAC designers
- Mechanical services contractors and installers
- Building services consultants and specifiers
- Manufacturers of ductwork hangers, brackets and suspension systems
- Facilities and maintenance managers
