COVERiT NovoProof®

DA-SK

Self-adhesive EPDM roll membrane

No separate field adhesive application.

The COVERiT NovoProof® DA-SK membrane comes with its own adhesive layer: it is fully bonded, so no separate field adhesive application is required. It can be laid directly on unfaced EPS (DAA dm/dh) and faced PUR/PIR (DAA dh). Bonding is also possible below +5 °C after a preliminary adhesion trial.

  • Press down the membrane Bond across the full prepared surface.
  • Fix the edges Also fix roof edges, valleys, upstands and roof penetrations linearly with suitable, approved fixings, 4 per metre (see the installation guide).
  • Close the seams Hot-air weld the ThermoFast® edges; the adhesive layer does not replace seam welding.

Hot-air weld ThermoFast® seams, weldable under site conditions down to approx. −10 °C; carry out trial welds first. Follow the bonding and welding conditions separately. Rolls come with a ThermoFast® joining edge along the long side. Unfaced EPS: DAA dm/dh.
