  • Profiles shall be extruded from EN AW-6060 (AlMgSi0.5 F22) aluminium alloy to comply with EN 573 – parts 3 and 4.
  • The assembly of suspension profiles and transoms is done by positioning the transoms partly forward of the suspension profiles. This method allows drainage of the transoms into the suspension profiles without interrupting the vertical drainage chamber. The sealing channels are provided with an EPDM end gasket that seals both suspension profile and transom without using any silicones. The applied transoms are fixed by means of stainless steel screws.
  • Dry glazed and weather-stripping with EPDM extruded synthetic rubber gaskets to DIN 7863 and ISO 3934, set in undercut grooves in the mullion and transom.
