KNAUF GYPSUM PLASTERBOARDS Type A, Type H, Type DF, Type DFH2 and type DFH2IR
Use advice for data set Scope: This is an EPD for an average product of the following products: - KNAUF gypsum plasterboard type A; - KNAUF gypsum plasterboard type H; - KNAUF gypsum plasterboard type DF - KNAUF gypsum plasterboard type DFH2; - KNAUF gypsum plasterboard type DFH2IR. These plasterboards are produced by: KNAUF Bulgaria EOOD Gypsum Plasterboards Plant 6294 Mednikarovo Galabovo municipality, Bulgaria The LCA considers specific information provided by the manufacturer and suppliers of components exclusively for the cradle-to-gate production stage. The owner of the declaration shall be liable for the underlying information and evidence; the IBU shall not be liable with respect to manufacturer information, life cycle assessment data and evidences. System boundary: This EPD covers the production stage in accordance with /EN 15804/, i.e. the scope is cradle-to-gate (Modules A1-A3). This includes the production of raw materials and their transport to the manufacturing site, the production processes, the packaging and the preparation for delivery, as well as the use of electricity, fuels and water.
Technical purpose of product or process Gypsum plasterboards are directly placed in drywall systems. The specific recommended applications of the products are as follows: - KNAUF plasterboard type A – interior drywall systems without special requirements: wall and ceiling panelling on metal framing construction, wall liner systems, partition walls and suspended ceilings; - KNAUF plasterboard type H – interior drywall systems in rooms with moderate humidity (kitchens, bathrooms): wall and ceiling panelling on metal framing construction and as a base layer for tiles; - KNAUF plasterboard type DF – interior drywall systems with requirements for fire resistance: wall and ceiling panelling on metal framing construction, wall liner systems, partition walls and suspended ceilings; - KNAUF plasterboard type DFH2 – interior drywall systems with requirements for fire resistance in humid rooms: wall and ceiling panelling on metal framing construction particularly (e.g. bathrooms in residential buildings); - KNAUF plasterboard type DFH2IR – partition shaft walls, wall panelling, suspended ceilings with increased requirements for sound insulation and fire resistance both in dry and humid rooms (kitchens, bathrooms, toilets). This plasterboard is appropriate in case of requirements for high mechanical resistance, higher walls and buildings with large people flow.

General comment on data set The plasterboard consists of gypsum core wrapped around and tightly glued to a durable and resistant paper layer. The paper surfaces are different depending on the specific type and use of the plasterboard and the core might include additives for improved properties. The declaration refers to the declared unit of 1 m2 of an average plasterboard product with a thickness 12.5 mm and average surface mass of < 10 kg/m2. This product in this EPD is a weighted average of the following products: - KNAUF gypsum plasterboard type A; - KNAUF gypsum plasterboard type H; - KNAUF gypsum plasterboard type DF - KNAUF gypsum plasterboard type DFH2; - KNAUF gypsum plasterboard type DFH2IR. The life cycle assessment results can be applied approximately to other board thicknesses, too.

Technology description including background system The manufacturing process is illustrated on the following figure. A gypsum slurry is made up from dehydrated FGD gypsum, raw FGD gypsum, water and other additives, in a continuous mixer (1). Rolled cardboard is supplied to a conveyor line (2). This slurry is spread (3), in a uniform stream, from multiple outlet hoses onto a moving rolled paper. The back layer (4) of paper is then laid from above and applied to the slurry. The front face paper is folded at the edges and the gypsum slurry is fully enclosed in paper. After that, the board is moved along the length of the production line on a series of setting belts, and sections of rollers (5). The plasterboard is then delivered at the shear (6) and is cut into panels with specific length. The panels are then turned over (7) and processed to a multi-level dryer (8). After the drying process is finished, the boards are trimmed (9) and arranged onto pallets (10). The pallets are covered with plastic foil and are placed for storage in the warehouse or they are sent for direct distribution (11). Technical data: /Regulation (EU) No.305/2011/ applies for placing of the declared products on the market within European union/European Free Trade Association EU/EFTA. KNAUF plasterboards are required to have declarations of performance and CE marking. Declared unit: The declared unit is 1m2 of KNAUF plasterboard with thickness 12.5 mm as an average of KNAUF plasterboard type A, KNAUF plasterboard type H, KNAUF plasterboard type DF, KNAUF plasterboard type DFH2 and KNAUF plasterboard type DFH2IR. Average surface mass of the plasterboard is 8.31 kg/m2 and is calculated as a weighted average value from the annually produced quantities of each plasterboard type.
