Installing DA-S
Laying methods
Installation steps
- Assess the existing roof Establish which layers may remain and how to prepare the substrate. The thick fleece backing evens out an uneven substrate.
- Secure the membrane Bond, mechanically fix or lay under ballast to suit the roof assembly.
- Fix the edges Bonded or mechanically fixed: 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 ThermoFast® overlaps and complete connections.
Hot-air weld ThermoFast® seams, weldable under site conditions down to approx. −10 °C; carry out trial welds before welding. Rolls come with a ThermoFast® joining edge along the long side. Also for balconies and terraces.
