DASATOP® an air resistive barrier for installation over rafters and across sarking in roof renovation projects. The DASATOP® air and vapour control layer system has been specially developed for roof restoration and is installed from the outside over existing rafters, sarking boards or structure. DASATOP® protects structures from rain wetting during construction while cladding is removed.
- Airtightness installed from the outside
- Specifically developed for roof restoration
- Humidity-variable MVTR
- No additional airtight joints required at the rafters
- High tear-resistance due to fleece reinforcement’
APPLICATION: DASATOP® is a humidity-variable vapour control membrane for installation over rafters and across sarking in roof renovation projects. The DASATOP® air and vapour control layer system has been specially developed for roof restoration and is installed from the outside over existing rafters, sarking boards or structure.
ADVANTAGES: Sub-and-top: The humidity-variable MVTR value protects the supporting structure and insulation layer; no difficult airtight joints required at the rafters; particularly tear-resistant thanks to fleece reinforcement.
