Abstract: A barrier laminate for attachment to the outer surface of a structure, such as a house prior to attachment of its siding, to cover joints between structural members assembled to form the structure. The barrier laminate comprises a flexible elongate barrier layer having minute passageways between its major surfaces affording passage of water vapor while restricting the passage of liquid water and air between its major surfaces. A portable carrier having a pair of hubs engaging a roll of the barrier laminate and having a pair of trailing rollers which may be used to adhere exposed layers of pressure sensitive adhesive along each of the opposite edges of the barrier layer to structural members on opposite sides of a joint therebetween.
