EN 15319:2007

General principles of design of fibrous (gypsum) plaster works

This European Standard defines the principles for the design of works carried out using fibrous (gypsum) plaster products as defined in EN 13815.
Fibrous (gypsum) plaster casts from the three categories of production below (see Clause 4 of
EN 13815:2006) should be involved:
a)   ”cpp” allowing regulatory marking CE;
b)   “cppv” allowing regulatory marking CE;
c)   “ipp” either when CE marking is required;
or without CE marking (see Annex D – Note 2 of EN 13815:2006).
This European Standard applies to both new constructions and to the refurbishment, restructuring or conversion of existing buildings.
The common fields of application of fibrous plaster are as set out in Table 1 below.
Table 1 — Common fields of application of fibrous plaster
Fields of application   Examples
Architectural effects      decorating: cornices, pilasters, columns (see exception vii below);
   on the ceiling: flat or shaped ceilings (included suspended ceilings), coffered ceilings, vaults, domes;
   in a vertical position : flat or shaped surfaces (partitions, linings);
   encasements, casings;
   embellishments for direct or concealed lighting;
   structures to improve acoustical performance (insulation, absorption, diffusion).
Technical functions      shafts and ducts for ventilation, air conditioning, smoke extraction;
   ceiling voids and chambers for pressurization;
   structures to enhance fire safety.
NOTE 1   This classification is not exclusive, as the same fibrous plaster work can have several functions.
NOTE 2   Table 1 does not mention the use of fibrous plaster externally; as it can only be used under certain conditions (see 4.3.1.2).
Fibrous plastering work should be capable of having the usual finishes applied directly to them (e.g. paint, wallpaper) subject to the normal preparatory work applicable for the type of finish.

Overview - EN 15319:2007 (fibrous gypsum plaster design principles)

EN 15319:2007, published by CEN, defines the general principles for design of fibrous (gypsum) plaster works (products as defined in EN 13815). It applies to fibrous plaster casts from the production categories “cpp”, “cppv” and “ipp” (CE‑marked where required) and is intended for both new construction and refurbishment, restructuring or conversion of existing buildings. Typical uses include architectural decoration (cornices, mouldings, coffered ceilings) and technical functions (ducts, ceiling plenum, fire‑protection structures).

Key topics and technical requirements

EN 15319 sets out the design framework rather than prescriptive product details. Major topics covered include:

• Design principles for installation and integration of fibrous plaster casts (thin reinforced gypsum mouldings).
• Functions - architectural effects (ceilings, mouldings, linings) and technical functions (ventilation shafts, ceiling voids, fire enhancement).
• Technical requirements for fixings, anchors, hangers, intermediate frameworks, sealed and screwed systems, and handling on site.
• Essential requirements and performance considerations (fire classification, acoustics, thermal behaviour referenced to relevant standards).
• Site arrangements - preparatory conditions before installation, materials, equipment and accessories (wads, fibrous ropes, anchors).
• Characteristics of completed works - surface appearance, flatness, verticality, suitability for direct finishes (paint, wallpaper) after normal preparation.
• Maintenance and repair guidance and informative annexes covering separations at abutments, thermal conductivity design values and painting works.

The standard also lists what it does not cover (e.g., fibre‑reinforced gypsum sheet products covered by prEN 15283, certain suspended ceilings covered by EN 14246, run‑moulded in‑situ plaster, external use under limited conditions).

Practical applications and who uses EN 15319

EN 15319 is practical for:

• Architects and interior designers specifying decorative plaster elements (domes, coffers, pilasters).
• Structural and MEP designers coordinating ceiling voids, ducts and service plenums.
• Contractors and installers selecting fixings and implementing sealed or screwed installation systems.
• Manufacturer and product specifiers ensuring conformity with EN 13815 categories and CE marking rules.
• Fire, acoustics and building performance consultants referencing complementary standards for classification and testing.

Using EN 15319 helps ensure fibrous plaster works are designed for durability, finish quality and integration with building services and safety requirements.

NOTE The column a "Decorating" concerns works consisting of casts set forward from background or supporting structure (see 3.1.16 and Figure 4). This European Standard should not apply to works consisting of casts and embellishments when they are to be applied directly to either new or existing wall or ceiling surfaces, for purely decorative applications (see scope-exclusion 7 and Figures 3 and 4).

f) Backgrounds consisting of existing ceilings: The use of these old ceilings or of their frame as a background should only be permitted, after investigation and testing, depending on their construction and provided that they are stable. Examples of such ceilings include:  reinforced in situ plaster ceilings; NOTE 1 These are ceilings formed from in situ plaster applied to elements fixed by nailing or stapling to a background or to elements which may be: - timber or reed laths - metal mesh or laths.  fibrous plaster ceilings;  plasterboard ceilings (cardboard faced boards). NOTE 2 In general, these old ceilings should only be retained in cases such as:  structural need;  need or choice to contribute to thermal resistance;  reasons of architectural and/or know-how preservation. g) Backgrounds not to be used: The use as a background of the following three types of old ceilings, including their framework, is not allowed:  suspended ceilings formed from terra cotta units;  suspended ceilings formed from plaster panels or tiles, laid dry in a special frame;  suspended ceilings in materials of mineral or vegetable origin or metallic or artificial materials. 4.3.2 Particular construction requirements 4.3.2.1 Passage of services equipment The contract documents, together with the working drawings and details should indicate where services equipment (e.g. ducts, lines, cables, pipework) pass through voids in the fibrous plaster work. The information relating to this equipment shall be given to the fibrous plastering contractor in tender documents and shall contain:  nature of the equipment;  size;  method of fixing;  location;  characteristics (e.g. temperature);
