Double-sided bitumen tape 50 mm – DSK nail sealing tape for permanently sealed nail penetrations
The double-sided self-adhesive DSK nail sealing tape is a cold-applied, carrier-free sealing tape for sealing nail penetrations in roof areas. It is applied between the underlay membrane and the counter batten and ensures that nail penetrations are reliably sealed afterwards thanks to its permanently elastic properties. The tape can also be used for sealing glass panels in greenhouses and conservatories as well as for sealing aluminum and plastic profiles.
