Fire-retardants serve to improve the reaction-to-fire performance of solid timber or wood-based materials treated with them. Through treatment with the fire-retardant, the solid timber or wood-based m

Fire-protective fabrics coated with an intumescent material are used to wrap electrical cables and services to improve their reaction-to-fire performance and/or to impede the breakout and spread of a

Sanitary appliances refer to those parts of a sanitary installation through which accumulating rainwater, foul or waste water is fed into the property drainage system (e.g. WCs, urinals, showers, bath

Non-return valves serve to prevent backflow of rainwater or wastewater from the connected sewer system into the parts of the property drainage system lying below the backwater level. Equipment for dra

Sewage lift stations are used to pump sewage from below the backwater level upwards so it can be drained via the public sewer system. Sewage lift stations usually have cutting devices for reducing the

These special thermal insulation products may be used as thermal insulation or substitutes for masonry facing and thermal insulation on stationary heating appliances assembled on site (e.g. stoves and

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

Corrosion protection systems are applied to the surfaces of metallic materials of low corrosion resistance. The primary goal is to extend the fields of use of such materials to more corrosive environm

The construction products described here are metal components formed by welding or soldering metal parts together. The construction techniques described here are structural works or parts thereof whic

Construction products and construction techniques for airborne sound insulation ensure that airborne sound insulation requirements in buildings can be met. Thermal and sound insulation products

Impact sound insulation products are placed under floating screed or used as part of suitable floor systems to improve the impact sound insulation of the floors. Usual delivery forms for the products

Pipe insulation products are used to insulate heating distribution and hot water pipes as well as cooling distribution and cold water pipes in buildings in accordance with the Buildings Energy Act (GE

These fasteners are used for rear fixing facade panels to the subframes of external wall cladding systems. The load-bearing parts of the fastener are made of stainless steel. The deformation-controlle

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

For accessories in the field of heating appliances that due to their innovative functions have not yet been covered by technical specifications, regulatory verification of fitness for use/application

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

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

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

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,

Micropiles serve to transfer axial tensile and/or compressive forces into the ground. They are used, among other things, as foundation elements. Micropiles are driven into the ground using drilling or

Soil nailing is a measure used to increase the tensile and shear strength of the soil to such an extent that the nailed soil can be considered as a monolithic block for verification purposes. Soil nai
