Overview
FprEN 14732 - "Timber structures - Structural prefabricated wall, floor and roof elements - Requirements" (CEN) defines performance characteristics, production requirements and conformity procedures for structural prefabricated timber elements. It applies to load-bearing wall, floor and roof elements built from timber framing (solid, glued, glulam, LVL, structural wooden beams/columns) with sheeting of wood‑based panels or gypsum boards, intended for service class 1 or 2 per EN 1995-1-1. The standard also sets requirements for marking, delivery performance information (Declaration of Performance), factory production control (FPC) and Assessment and Verification of Constancy of Performance (AVCP).
Key topics and requirements
- Materials and components: framing members (structural timber, finger‑jointed, glued solid timber, glulam, LVL), wood‑based panels, gypsum boards, adhesives, mechanical fasteners and connectors.
- Element limits and types: maximum dimensions and build-ups are specified (e.g., wall elements up to 16.5 m length and 3.2 m height; glued floor/roof elements up to 12.5 m length with specified cross‑sectional thickness). Both glued and mechanically fixed elements are covered.
- Performance characteristics: mechanical resistance, bonding strength (bond shear tests and wood‑failure percentage), thermal insulation, water‑vapour permeability, moisture resistance, durability, tolerances and moisture content at assembly.
- Fire and health considerations: reaction to fire classification, fire resistance provisions (note: elements treated specifically to enhance fire performance are excluded), and release of dangerous substances (e.g., formaldehyde).
- Production and quality control: requirements for Factory Production Control (FPC), type testing, test reports, minimum production provisions, cramping and bonding requirements, and AVCP procedures aligned with the EU Construction Products Regulation.
- Documentation: element documentation, marking, labelling and provision of performance data at point of delivery (DoP).
Applications and who uses it
FprEN 14732 is intended for:
- Manufacturers of prefabricated timber wall, floor and roof elements to ensure design, production and delivery meet European performance requirements.
- Structural engineers and designers specifying load‑bearing timber prefab systems in compliance with EN 1995-1-1 (Eurocode 5).
- Architects and contractors integrating factory-made timber panels into building projects.
- Testing laboratories and certification bodies performing bond shear, mechanical and durability tests and overseeing AVCP/FPC.
- Compliance officers preparing Declarations of Performance and assessing conformity under the Construction Products Regulation.
Related standards
- EN 1995-1-1 (Eurocode 5) - design of timber structures (service classes referenced).
- EU Construction Products Regulation (CPR) - AVCP and DoP procedures referenced in the standard.
FprEN 14732 is essential for anyone involved in the manufacture, specification or certification of structural prefabricated timber elements, providing a consistent framework for performance, testing and factory quality control.

In this case the manufacturer has to declare the mechanical resistance and fire resistance performances of the structural elements by reference to dated drawings of the element, providing information on the geometrical data, and to the performance characteristics of the materials and/or the components (including dimensions) and allowing subsequent structural assessment by the purchaser. Method M2: This declaration method is applied when the final place of destination is not known but the manufacturer wishes to provide information on the mechanical and fire resistance performances, under certain assumptions, of the structural elements (e.g. off-the-shelf or catalogued structural products) and the calculation methods of the Eurocodes (with the relevant NDPs) are used.
In this case the manufacturer has to declare the mechanical resistance and fire resistance performances of the structural elements, expressed as characteristic or design values as relevant.
Method M3a: This declaration method is applied when the intended place of destination is known, the design documentation of the product is prepared by the designer of the works of destination and made available by the client and the manufacturing order requires the relevant production documentation to be prepared by the manufacturer for a specific works of destination. In this case the manufacturer has to declare the mechanical and fire resistance performances of the structural element by reference, in an unambiguous way, to both: — the design documentation of the structural element(s) (drawings, material specifications, etc) provided by the client; and — the production documentation prepared by the manufacturer on the basis of the relevant design documentation, including information on the materials and/or components used. In addition, reference has to be made in the declaration to the specific position of the structural element in the works. Method M3b: Declaration method that may be applied when the intended place of destination is known, and the manufacturing order requires design and production documentations of the product to be prepared by the manufacturer for a specific works of destination.
