A double-skin tank is a tank in which there is a second skin at least up to the height of the maximum permitted filling level and the interstitial space between the inner and outer skin is suitable as

Staples are used in timber construction to permanently connect elements (e.g. wood-based panels, gypsum boards, wood-fibre insulation products) with timber elements. Mechanical fasteners in timber con

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

Systems for limiting hydrocarbons in mineral oil containing wastewater with biodiesel, bio heating oil and ethanol contents are systems for treating wastewater containing up to 100% biodiesel and bio

Prestressing steel bars are used in various prestressing systems for concrete structures. Prestressing steel bars are manufactured in hot rolling mills (by quenching, cold-drawing or additional temper

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

The construction products described here are components made of metallic materials with special properties in comparison to commonly used materials of the same type. The construction techniques descri

With structural sealant glazing, glass panes are bonded to frame profiles at the factory (primarily using silicone adhesive and with a linear adhesive bead). This prefabricated structural sealant glaz

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

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

Liquid-tight collecting trays and devices are enclosures serving to meet the requirement for secondary containment under water law. They are used to collect and retain substances hazardous to water le
