Non-combustible building materials ensure that, when exposed to fire – especially an advanced or fully developed fire – the relevant parts of the structural works do not contribute to the fire. Reacti

The work area 'Strengthening of concrete structures with textile-reinforced concrete' comprises kits for retrofitting aimed at increasing the flexural strength of concrete structures (strengthening) w

The revised Construction Products Regulation (EU) 2024/3110 was published in the Official Journal of the European Union on 18 December 2024. It entered into force on 7 January 2025. English version cr

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

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

For penetration-free fixing of photovoltaic systems or fall protection to the roof, the fixings can be bonded or welded to the roof waterproofing membrane. The roof waterproofing thus takes on a struc

Walk-on glazing is designed for foot traffic. A vertical imposed load of maximum 5 kN/m 2 is assumed under normal use conditions. Glazing accessible for maintenance and glazing with fall-through prote

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

Overhead glazing (also known as 'horizontal glazing') is understood to be glazing with an angle of inclination of more than 10° with respect to the vertical plane. With overhead glazing, it is assumed

With point supported glazing, the glass pane is mechanically fixed to the substructure either via point fasteners installed in drilled holes or via clamps (edge clamps). Point supported glazing is use

Single-room ventilation units ensure a controlled air exchange between the building interior and the outside environment which is independent of the ventilation behaviour of the occupants. Ventilation

A prefabricated stair system consists, e.g., of steps, landings, stringers, handrails, balustrades and fasteners. The following stair systems are distinguished: stairs supported by load-bearing bolts,

Pipes, fittings and inspection chambers are parts of rainwater or waste water drains for property drainage. They serve to ensure the safe discharge of surface water and/or waste water from the propert

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

Sealants for drains serve to prevent, in connection with pipework parts such as pipes and fittings, the leakage of discharged waste water. In the case of underground drains, the sealant also ensures t

Trenchless rehabilitation techniques are increasingly being applied in wastewater engineering today. For the rehabilitation of underground supply pipes and drainage pipes, techniques such as lining wi

Inner linings are prefabricated elements used for on-site lining of drains and manholes. They usually serve to improve corrosion protection. Inner linings must be fixed durably and tightly to the drai

Infiltration elements form part of the property drainage system. They serve to store or retain rainwater. If infiltration elements are used on a property, it must be ensured that no dangers to the adj

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

Mastic or roller-compacted asphalt sealing layers are used in storage and filling facilities for manure, slurry and silage effluent (MSS facilities) and biogas storage and filling facilities (biogas S

Drainage channel systems and penetrations in retaining systems need to be designed in a way to ensure that no substances hazardous to water can escape from storage and filling facilities for manure, s

Joint sealing systems, e.g. sealing strips, sealing sheets, sealing tapes, coated sealing sheets and sealing compounds, serve to make construction joints in sealing surfaces or sealing systems of stor

Mastic or roller-compacted asphalt sealing layers are used in storage, filling and handling facilities for substances hazardous to water (SFH facilities) to create load-bearing, liquid-tight, sealed s

Semi-rigid sealing layers are used to create load-bearing surfaces in retaining systems, e.g. collecting rooms, collecting trays and surfaces, in storage, filling and handling facilities for substance
