Tafficable roof under rolled asphalt


SOPREMA SYSTEM without thermal insulation

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.
  • A ≥ 2% slope will avoid water stagnation and the risk of foul odours.
  • With high SOPREMA adjustable support pads, upstands can be hidden to reduce the height to 10cm without mechanical protection.
  • The self-protected cap sheet provides further fire protection and easy maintenance (self-washing and non-adhered support pads).
  • SOPRAVAP® 3 IN 1 is an optimal solution combining three functions: primer, vapour barrier and insulation adhesive. Do not hesitate to contact our technical team for advice.
