Glossary Architectural Mesh
„aw“, „as woven“
HAVER Architectural Mesh is manufactured from high-quality wires on weaving machines which were developed and assembled by Haver & Boecker’s engineering specialists.
Sound-absorbing material, which can be concealed with architectural mesh. Can also be integrated directly into cassette systems with architectural mesh.
Aperture Width (w)
Aperture width, w, is the distance between two adjacent warp or weft wires, measured in the projected plane at the mid-positions.
Woven wire mesh for the use in architecture. In the selection of the material, the production and the processing as well as the fastening, the demands of an optical application as well as the loads have to be taken into account.
Also known as: architectural wire mesh, architectural fabric, wire mesh, metal mesh, stainless steel mesh, mesh fabric, metal fabric
A wire mesh, which is made in the warp direction of rope, also called cable mesh. It is flexible in direction of the cables and robust in direction of the rods. Due to the flexibility in the direction of the cables, cable meshes can be deformed into narrow radii.
The woven wire mesh is rolled to a specified thickness, simultaneously producing a smooth surface. For fine mesh, this can also influence the filtration criteria of the mesh.
Ceiling Lining / ceiling cladding
Ceiling linings are non-load-bearing ceilings, which are attached to a substructure. With different ceiling systems, measures for thermal and sound insulations can be connected. Depending on the system you can distinguish between surfaces, sheets or grid structures.
Haver & Boecker's quality management system is certified according to DIN EN ISO 9001:2008. The company's automotive area is also certified according to the especially high standards of ISO TS 16949.
Wire mesh is often used in stainless steel look. However, there are also various possibilities available for individual coloring of stainless steel wire mesh.
Sequenced curvature of a wire as a result of pre-deformation or weaving.
The curtain wall carries only its own weight and no other static loads. It is fixed by of a substructure on the building.
Media façade systems are suitable for daylight, if the content can be presented in full daylight.
By digital printing, complex graphics and pictures can be applied to architectural wire mesh. Even photos and very detailed pictures can be displayed. The visibility depends always on the selected wire mesh as well as the viewing distance. For exterior applications (e.g. on facades) an additional UV-resistant protective coating is used to protect the images against environmental impact.
Standard of DIN (German Institute for Standardization).
DIN EN ISO 9001:2015
Standard related to quality management systems that contain the areas development, production, assembly and customer service.
Expanded metal or expanded metal mesh is cut material which is simultaneously stretched. It is neither braided nor welded and is formed from a single piece of metal.
The facade cladding is attached in front or to the supporting wall construction of a building. Different materials can be used so that a variety of design possibilities are available for the exterior wall cladding. The exterior envelope of a building has not only optical function, a façade cladding can also be important for thermal insulation, sun protection or fall protection.
Fine Wire Mesh
Fine wire meshes are mesh types which are produced from wires with a very small wire diameter. The classification as fine mesh is essentially dependent on the particular application. Whereas for industrial applications mesh types with an aperture < 0.2 mm are referred to as fine wire meshes. For architectural applications, clearly larger mesh types are also called fine mesh. For architectural applications, all types of wire meshes are classified as fine mesh, which are very sensitive to mechanical stresses. Due to their small mesh width and the filigree wires they are more suitable for indoor applications.
All preventive measures, which prevent formation or spreading of a fire, are summarized under the term fire protection. In this context, the use of a wire mesh is helpful because it can contribute to a smoke extraction with correspondingly large open area.
Flat Wire Mesh
Wire mesh, which is made of flat wires or split strip. Due to the width of the wire, flat wire meshes have a large surface area and a lighter weight compared to round wire meshes with the same open area.
= overall energy transmittance
The g-value represents the permeability of transparent components with regards to the energy transport. It indicates the percentage of solar energy, which penetrates through a component (e.g. window). For example: A g value of 0.6 means that 60 % of the solar energy enters the interior. The rest of the radiated energy is reflected or absorbed. The entire façade system has to be assessed for the use of wire mesh as sun protection in combination with a glass façade.
DIN EN ISO 9001:2015 specifies the requirements for a quality management system (QMS). A certification process provides proof of compliance. Haver & Boecker was one of the first companies to be certified according to DIN EN ISO 9001 as early as 1997.
The transparent media façade system IMAGIC WEAVE® a fusion of HAVER Architectural Mesh and state-of-the-art LED technology.
The maximum resulting loads on the substructure as well as the possible deflection of the mesh are reduced by intermediate fixings. Usually, an intermediate mounting is recommended at the height of a floor slab (about 3 - 4 m).
Distance of an image point within a media facade, measured in each case from the center of the image point. A pixel may here also consist of several individual LEDs.
Leadership in Energy and Environmental Design: 1998 Developed classification by the U.S. Green Building Council for ecologically construction. Defines standards for environmentally friendly and sustainable building.
Light Emitting Angle
The light emitting angle defines the emission range of an LED in which at least 50 % of the maximum brightness of the light source / LED is achieved.
A wire medium produced in a weaving process, which is used for technical and design applications.
Through different mesh widths and geometries as well as different weave types, different structures of a wire mesh can be achieved. That offers architects and designers a variety of design possibilities.
Geometry of the openings of a mesh, e.g. referred to as square mesh, long mesh, wide mesh or zero mesh.

Various fastening systems have been developed for the application of architectural mesh elements. For each project the suitability and feasibility of the selected solution has to be checked individually.
Copper and Copper based Alloys as copper, brass and tin bronze referred to as non-ferrous metals. Wire mesh can basically made of a wide variety of metals. Nevertheless, with many metals, you should be careful with their optical characteristics.
In the case of non-ferrous metals, it must be ensured that their surface can be tarnish under atmospheric conditions, so that a homogeneous appearance is no longer guaranteed. Furthermore, the strength of the material is limited according to the installation situation.
Alternatively, stainless steel mesh can be provided with a corresponding metallic painting.
In the planning of car parks, the opening proportion of the façade cladding plays an essential role in ensuring adequate ventilation of parking garages. In order to achieve an "open facade", a wire mesh is often used with a correspondingly matched open surface.
Open Area, Ao
The percentage of the area of all the apertures between the wires in relation to the total area.
Applying a colorless or colored lack to an object or a surface. Architectural mesh can be painted in almost any color. Customized individual logos and patterns can be realized on a façade or wall cladding. Also metallic effects can be achieved with a painting.
Perforated plates are made from, for example, stainless steel, aluminum, zinc, steel and brass. In practice often referred as perforated metal.
The distance between the middle point of two adjacent wires or the sum of the aperture size w and the wire diameter d.
Type of weave wherein each warp wire alternately crosses over and under each weft wire.
Process for protecting the metal surface from corrosion. Using an electrolytic process, dry powder is sprayed onto the grounded stainless steel mesh and melted in a kiln. The resulting uniform coating film is particularly robust and dirt-repellent. High quality powder coatings are available in almost all RAL colors. Due to its stability, this method “fixes” the wire mesh and thus the mesh loses its flexibility. For this reason, a painting is often used for designing wire mesh.
The preload is the initiated tension during the installation. For the interpretation of the substructure, the maximum occurring in operating load is decisive, which is to be determined individually for the needs of a project.
