SOPREMA SYSTEM on inverted roofs

Soprema advices:

  • Upstand variant: Alsan® FLASHING (European Technical Approval ETA-08/0114) will avoid the use of counter flashing protection on parapets. This no-flame system is easy to apply and saves application time.
  • Time saved: addition of silica on the fresh top coat of Alsan® FLASHING to be used with adhesive mortar.
  • In high frost-risk areas, 3cm thick ballast with the separating and protective geotextile NTS 170 is required.
