Abstract
An edge of a moisture barrier membrane, such as of a roof assembly, is attached and sealed using a moisture-impermeable sealing tape. The membrane has a fibrous surface and a non-fibrous surface. The tap is secured to a surface to which the edge of the membrane is to be attached, and positioned to underlie and extend along the edge of the membrane. The tape has a first edge width carrying a field of discrete touch fastener elements, and a second edge width carrying a layer of adhesive. The fibrous surface of the moisture barrier membrane is engaged against the field of touch fastener elements, such that the moisture barrier membrane overlaps the first edge width of the tape, and then the sealing tape is folded over the edge of the moisture barrier membrane, such that the adhesive engages the non-fibrous surface of the moisture barrier membrane.
