In timber construction, screws are used to permanently connect timber elements to other elements or to reinforce timber elements. In this work area, you will also find threaded rods and screws for ext

Temporary structures are repeatedly erected and taken down. They include, for example, bleachers, tents and rides for fairgrounds. Temporary structures are special structures within the meaning of Sec

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

Gypsum plasterboards and gypsum fibre boards are used in timber construction as cladding for walls and floors. Roofs, walls, facades

A plastic fastener consists of a plastic sleeve and a steel or plastic expansion element. The plastic fastener is placed into a pre-drilled hole in the base material and anchored through expansion of

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

Wastewater treatment systems for compressor condensates serve to treat wastewater resulting from compressed-air generation in compressors to such an extent that the treated effluent can be introduced

Tanks and collecting devices made of plastic are especially suitable for liquids hazardous to water because they often have a more favourable corrosion behaviour than metal tanks and hence are resista

Headed bolts are made of round steel or reinforcing steel bars. The bars are headed at one end. A thread is rolled on or cut at the other end of the bar. The end can also be prepared for welding on of

Supply ventilation units serve to supply indoor spaces with filtered and possibly preheated outside air. Exhaust ventilation units serve to remove exhaust air from indoor spaces. Ventilation

Connectors (clamp connectors and/or couplings) for drains are designed to connect pipework parts such as pipes and fittings permanently such that no waste water can escape from the joints. In the case

Metal fasteners are post-installed mechanical fasteners for use in concrete. They are placed in pre-drilled holes and anchored in concrete through friction and/or an interference fit (mechanical inter

Punching shear reinforcements are special reinforcements used in place of stirrups or bent reinforcements to increase the punching shear resistance in the area of beam supports for reinforced concrete

Modular scaffolds are scaffolds in which standards, ledgers and diagonal braces are connected through special connections made of multiple components, called module nodes. Working scaffolds in accorda

A bonded fastener consists of a fastening element and a bonding material (mortar). Bonded fasteners are available as injection systems or cartridge systems. They are placed into pre-drilled holes and

Ancillary components and accessories comprise all construction products which, in addition to masonry units and mortar, are needed for the erection of masonry structures. These construction products a

Liquid applied roof waterproofing kits are usually multi-component systems and are applied in liquid form in multiple layers. After curing, they form the roof waterproofing. Waterproofing of buildings

With their very low thermal conductivities, insulation products play an important role in thermal insulation and in improving the energy performance of buildings. A multitude of different materials ar

Systems for restoring the leak tightness of sealing systems made of concrete in storage, filling and handling facilities for substances hazardous to water (SFH facilities) are used for the repair of d

Systems for restoring leak tightness of sealing systems made of concrete in storage and filling facilities for manure, slurry and silage effluent (MSS facilities) and biogas storage and filling facili

An electric panel forms part of the electrical wiring system for safety systems required under the Building Codes. The functions of these systems must be maintained in case of fire for the required du

In ventilation units using heat pump technology, the ambient heat, e.g. the heat from the earth or the heat from the outside air, is used for space heating. Common variants include: ventilation unit w

Ventilation units with heat recovery serve to supply and remove air from indoor spaces while transferring the residual heat from the exhaust air to the supply air via a heat exchanger. Ventilation

External thermal insulation composite systems, or ETICS for short, are multi-layer systems used to insulate the external wall of a building. The ETICS consists of insulation boards, a type of fixing a

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
