Vapour barrier adhesive tape for a roof ridge purlin

摘要

The vapor barrier strip(2) is NOTLESS 35cm wide and has a single-sided adhesive barrier strip(4) along both long edges(3). Each adhesive edge strip has a removable protective strip(7) to prevent premature adhesion to a surface. An Independent claim is made for a method for producing a vapor tight connection on a roof construction using the claimed vapor barrier strip(1) in which the strip is placed over the ridge purlin and the protective strips(7) removed to allow the adhesive edge barrier strips to bond to adjacent vapor barrier strips.
