About DWF Handel + Systembau
DWF Handel + Systembau GmbH, based in Ettenheim (Baden-Württemberg), has been active in roof, wall and facade technology for industrial and commercial buildings since 1989. As a full-service provider, the company offers everything from planning and design through delivery of roof, wall and facade elements to installation and acceptance. In the roof sector, the team realises trapezoidal sheet metal roofs in single- and double-shell designs, roofs with sandwich composite elements with PU foam or mineral fibre cores, and industrially prefabricated system and standing seam roofs. For walls, cassette profiles with facing shells as well as single-shell constructions made of trapezoidal and corrugated profiles are used; in the facade sector, system facades with panel profiles, trapezoidal and corrugated profile facades as well as individually manufactured special facade profiles, including panels from Trespa, Eternit or Fundamx, are installed. The range of services is complemented by the refurbishment of asbestos-containing roofs and facades in accordance with TRGS 519, roof sealing with plastic and bitumen membranes, green roofs, roof light strips, skylights, smoke and heat extraction systems (SHEVS), roof drainage, and a maintenance and support service. Projects are carried out throughout Germany as well as in neighbouring countries; since 2015, the group has consisted of DWF Handel + Systembau GmbH and DWF Dach + Fassadentechnik GmbH.
