ADHESIVE VAPOUR BARRIER TAPE FOR A RIDGE PURLIN

摘要

The present invention relates to a single-sided adhesive vapour barrier tape 1 having a vapour barrier strip 2 which has a width BD between 40 cm and 100 cm and, on each of its two long edges 3, has a single-sided adhesive vapour barrier strip 4, each adhesive vapour barrier strip 4 being provided on its adhesive side with a protective means 7 which can be pulled off separately and prevents inadvertent adhesion of the adhesive strips 4. This adhesive vapour barrier tape is particularly suitable when producing a vapour-tight joint at a ridge purlin. In addition, the invention relates to a method of producing such a vapour-tight joint when finishing a roof at a ridge purlin.
