Gypsum boards with fibrous reinforcement

Gypsum boards with fibrous reinforcement (gypsum boards with mat reinforcement) is a flat panel material with a plaster core and a woven or non-woven coating made of organic and/or inorganic fibers. The core can also contain fibers, additives and fillers in order to achieve additional properties. According to EN 15283-1, fiber-reinforced plasterboards are to be identified with the type designation “GM”. Depending on the performance features, specific letters must be added to this type designation, similar to those of the plasterboard. They are primarily used as wall and ceiling cladding in rooms with increased requirements in terms of moisture resistance and fire protection.

Fibre-cement flat sheets

Fibre-cement flat sheets essentially consist of cement or calcium silicate, fiber material and water. The mostly synthetic, organic reinforcement fibers made of polyvinyl alcohol or polyacrylonitrile and process fibers (cellulose) can be added in different forms (fiber bundles, ribbons, nets, etc.). The small-format to large-format panels - the usual thicknesses of which are between 3 - 30 mm - are regulated in the european standard EN 12467. Due to their very good fire protection, moisture-related and mechanical properties, these panels can be used in a wide range of applications - they are used as wall and ceiling cladding both for interiors (e.g. in dry lining) and for outside (e.g. as plaster base panels). The smooth or structured fiber-cement sheets can be colored, left in their natural color and provided with coatings on their surface.

Gypsum plasterboards

Gypsum plasterboards are flat, rectangular panels made of a gypsum core and a cladding made of strong, resistant cardboard that is firmly adhered to it. They are regulated in the European standard EN 520. With regard to their application, plasterboards are selected according to their type, shape, thickness and edge formation. The cardboard surfaces can vary depending on the intended use of the respective type of board and the core can contain additives that give the board additional properties, e.g. with regard to fire and sound insulation. Gypsum boards are given a type designation for their performance features. Plasterboard can have several performance characteristics. Gypsum boards are used for wall and ceiling systems, as cladding for stud walls and cladding, and for the manufacture of prefabricated components.

Gypsum fibre board

A gypsum fibre board is a reinforced material consisting of gypsum and cellulose fibres. These two raw materials are mixed and after the addition of water (no other binding agents) they are pressed under high pressure to form panel sheets. Subsequent to drying, the panels are impregnated with a hydrophobic agent and cut into the desired sizes. With the exception of exterior applications, gypsum fibre boards can be used in all areas of dry wall and timber construction as panelling and lining in walls, ceilings, vaulted ceilings and floors. Gypsum fibreboards are inflammable and are classified A1 or A2 according to EN 13501-2.

Cement-bonded reinforced lightweight concrete board

A cement-bonded reinforced lightweight concrete board is a cementitious building board, which due to the addition of different additives such as foamclay or granulated recycled foamed glass have a reduced density (approximately 1000 kg/m³). These panels are reinforced on both faces with a woven glass fibre fabric. It exhibits high strength and stiffness values and is inflammable (Euroclass A1). Due to its water repellent treatment, which eliminates water uptake, this panel is particularly suited for applications in domestic wet rooms (bathrooms). This type of panel can also be used in exterior applications as lining and as a plaster baseboard.
