Timber structures - Prefabricated wall, floor and roof elements - Structural elements with mechanically fixed sheeting made of wood-based boards/panels or gypsum boards/panels on both faces (EN 14732-1) cen:proj:77986

Scope

This European Standard sets out provisions regarding the performance and characteristics of structural (load-bearing) factory prefabricated wall, floor and roof elements consisting of framing members of structural timber, structural finger jointed timber, glued solid timber, glued laminated timber, laminated veneer lumber (LVL), composite wood based beams and columns, and sheeting made of wood-based boards/panels, gypsum boards/panels or insulation material fixed mechanically on both faces, for use in service class 1 or 2 in accordance with EN 1995-1-1. At least one sheeting may contribute to the structural capacity of an element.
The cavities of the prefabricated elements may be filled entirely or partially with insulating materials. The exterior faces of the elements may also be covered with insulation material. The elements may contain water vapour control layers.
This European Standard specifies characteristics of load bearing and non-load bearing components for the prefabricated elements.
This European Standard applies to elements and components treated or untreated with a preservative against biological attack. This European Standard applies to prefabricated elements that may have openings, e. g. for windows, doors etc. It does not apply to the characteristics of incorporated doors or windows.
The elements may be used in seismic areas with adequate design and materials.
This European standard covers wall, floor and roof elements with unlimited sizes.
This European Standard does not cover curved elements
This European Standard does not cover elements intended for use in fatigue actions.
This European Standard does not cover elements with framing members with holes except for round holes at mid-depth with a diameter  1/10 of the framing member depth.
This European Standard does not cover components and prefabricated elements treated with fire retardants.
This European Standard can also be used to specify the performance and characteristics of non-load bearing elements.
This European Standard also specifies marking and labelling of the elements.
