A single-room heating appliance is a heating appliance which serves to heat the room in which it is placed or installed. Heating appliances, chimneys

A hold-open device is a system of devices or device combinations suitable for the controlled disabling of the function of closing devices. Hold-open devices may be used on fire doors, smoke control do

Concrete constituents

Leak detection linings serve to create a second skin within the meaning of water legislation in single-skin tanks or containers. For this purpose, an internal lining is inserted into a single-skin tan

Chimneys for solid fuels serve to discharge flue gases from the combustion of solid fuels into the outside atmosphere via an outlet above roof level. They can also be used to discharge flue gases from

Coatings for resilient floor coverings can consist of several layers and/or products and be one-, two- or multi-component systems. Polyacrylates, polyurethanes, epoxy and alkyd resins and others are u

Universal adhesives are used across large surface areas to bond floor coverings to the substrate. They can consist of one or two components. Acrylate dispersions, epoxides, polyurethanes, silane-modif

Floor coatings are applied to load-bearing substrates. Such coatings – for example, based on synthetic resin – can be used immediately after curing. They can be made up of multiple layers and differen

Masonry is made from masonry units bound by mortar or other bonding agents and possibly other accessories. Different techniques are used to produce masonry for different application areas. In many cas

Masonry wall elements are room-height and predominantly room-width prefabricated elements (including parapets and gables). The individual masonry wall elements are manufactured at the factory from mas

In timber construction, a large variety of glued timber and wood-based products are used for a wide range of uses. These include: glued laminated timber, glued solid timber, plywood, laminated veneer

Tension rod systems and cable tension members are used, for example, for trusses, suspensions, cross bracing and wind bracing, particularly in engineering works (new structures) but also in the repair

Flue gas heat exchangers transfer the thermal energy from the heating appliance flue gas to the heating water. This increases the efficiency of the heating system. Heating appliances, chimneys

Waterproofing sheets and membranes are available for various applications (e.g. for roofs or elements in contact with soil). Waterproofing sheets and membranes can be divided into plastic and bitumen

Barrier glazing is glazing designed to prevent people from falling to a lower level. In the event of impact on the glazing, the risk of injury is supposed to be low. Furthermore, the lower-lying traff

Masonry is made from masonry units using mortar or other bonding agents or not. Different techniques are used to produce masonry for different application areas. In many cases, the masonry units for t

Intumescent products are fire-stopping and fire-sealing products which foam up or expands permanently when exposed to high temperatures which creates a fire-sealing effect. The expanded product seals

Inner coatings (as partial or full surface coatings) are applied to the inner surfaces of stationary steel tanks for the storage of liquids hazardous to water to make them liquid-tight. Similarly, the

Wood floor coatings can consist of several layers and/or products and be one-, two- or multi-component systems. Polyacrylates, polyurethanes, epoxides, alkyd resins, curing oils, waxes and others are

Underlays are installed underneath the flooring or floor covering to provide insulation against noise, a barrier between the flooring and the substrate as well as to provide additional thermal insulat

Cross-sectional reductions for existing chimneys are used for renovation and/or modernisation. The purpose may be to upgrade the chimney for operation under wet conditions or adapt the cross section o

Catalysts are used in firing systems to optimise the combustion processes and reduce the amount of harmful flue gas substances produced. Heating appliances, chimneys

Dust separators are used in chimneys to reduce the dust particle content of flue gases resulting from the combustion of solid fuels. Heating appliances, chimneys

Structural bearings are components that allow for relative rotation of parts of structural works, transfer loads and permit or prevent displacements in one or more directions. The most common bearing

Thermoplastic tanks are especially suitable for storing certain liquids hazardous to water because they often have a more favourable corrosion behaviour than metal tanks and hence are resistant to var
