Applications

  • Roof waterproofing

  • Without ballast

  • Green roofs

  • Under wearing layers

  • All types of substructure

  • New construction and refurbishment

  • EN 13501-5 Broof (t1) for tested constructions

DA-F sheet: From plan to roof

Laying methods

  • With ballast

    The specified gravel, green roof or trafficable layer secures the loose-laid membrane.

  • Loose-laid

    The waterproofing is laid loose; the seams are joined with ThermoFast®.

  • Mechanically fastened without penetrations

    Mechanical fixing without penetrating the roof membrane.

Installation steps

  • Measure and calculate wind uplift Survey the roof and details. The project-specific calculation determines plate quantity and positions.
  • Prefabricate and prepare Integrate agreed connection details at the factory. Install specialist plates to the roof fixing plan.
  • Induction-bond Unroll the sheet and bond it to the plates. Close remaining seams and connections; inspect the area.

This sequence is for induction fixing. BROOF(t1) applies only to tested roof assemblies. Sheets are prefabricated to size at the factory. Hot-air weld ThermoFast® seams, weldable under site conditions down to approx. −10 °C; carry out trial welds first.
