Pipes for the conveyance of liquids hazardous to water are executed with special inner coatings or linings to make them liquid-tight. Inner coatings and linings for pipes and tanks for liquids hazardo

for filling ducts for internal bonded tendons or sheaths for external tendons. It serves to establish a form and interference fit between the concrete and the prestressing wires and to provide corrosion

Adhesives are used in timber construction for the manufacture of glued elements and for the bonding of elements, including glued-in threaded rods or sheets, or for screw-press bonding. This page addre

for solid fuels must be designed to be resistant to soot fire. The chimneys must be designed in such a way that no flue gases can escape into living areas and surrounding building components are not exposed [...] as system chimneys or as custom-built chimneys. System chimneys are characterised by the fact that a single manufacturer is responsible for all of the different components included in the modular design

tanks or pipes into the collecting device. In this case, a visual and/or acoustic signal is triggered. Leakage indication systems are based on a wide variety of detection mechanisms, from pure liquid level

Pile couplers are used for connecting segments of prefabricated foundation piles when the required pile length exceeds the maximum as-delivered lengths. Earth work and foundation engineering

made of stainless steel. The deformation-controlled or torque-controlled fastener is inserted into a drilled hole or an undercut hole in the facade panel. The anchoring is achieved by mechanical interlock

fire-sealing products which foam up or expands permanently when exposed to high temperatures which creates a fire-sealing effect. The expanded product seals gaps, voids and cavities and restricts the passage of

Translucent roof or wall systems are composed of single- or multi-layer flat or curved plastic sheets generally supported by aluminium support profiles and their fasteners. They are used both for roof

An inverted roof is an arrangement in which the thermal insulation system is positioned above the roof waterproofing. Due to this special 'upside down' arrangement, both the insulation products (XPS a

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

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

mechanically fixed directly to the load-bearing wall as external wall cladding. A composite insulation element consists of a thermal insulation layer and an outer weather protection layer. Thermal and sound

Ablation coatings are fire-stopping and fire-sealing products which are activated when exposed to high temperatures due to their chemical compositions. Chemical and/or physical reactions are triggered

Separator systems for light liquids serve to separate light liquids of mineral origin from commercial wastewater. Separator systems

A power-actuated fastener is a bolt made of steel with a bolt head or threaded connection also made of steel. It is driven into the concrete with the help of a power-actuated fastening tool with or without [...] systems) to concrete members. One advantage of power-actuated fasteners is that they can be installed in a simple and time-saving manner using cartridge-fired bolts. Post-installed fastening systems

Liquid polymers are used for waterproofing of buildings. The waterproofing system can feature other components (e.g. reinforcing inserts, sealing tapes and collars) in addition to the liquid polymer.

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

A fire-resistant partition with opaque and/or glazed panels is a non-load-bearing internal wall, usually consisting of a subframe (mullion and transom) clad on both sides (usually with mineral boards and [...] and panels) and/or a fire-resistant glazing, joint sealing materials and fasteners meeting certain requirements related to fire resistance (class F ...). Fire resistance of walls, ceilings and special

Fire-resistant glazing is a non-load-bearing building component, usually consisting of one or more translucent elements, a frame and fixings, seals and fasteners which meet specific fire-resistance re

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
