Polymer batten with adhesive backing

A self-contained composite roofing batten bar has a layer of adhesive material secured to the bottom or undersurface portion of a roofing batten bar or strip. The adhesive material is tacky or sticky at room temperature and preferably comprises a butyl rubber composition. In view of the inherent tackiness or stickiness of the butyl rubber adhesive composition, one surface of the adhesive material layer is inherently adhered to the bottom or undersurface portion of the roofing batten bar or strip, and the other lower or undersurface portion of the adhesive layer is covered by a releasable paper backing strip. When it is desired to use the composite batten bar in order to secure, for example, a roofing membrane to underlying roofing structure, the releasably paper backing strip is simply removed thereby exposing the lower or undersurface portion of the adhesive layer. The batten bar or strip is then able to be mounted upon or atop the roofing membrane at predetermined locations as dictated by the overall roofing installation requirements. The batten bar or strip may be provided with preformed apertures or holes for the reception of suitable fasteners such that the batten bar and roofing membrane assembly may be fixedly secured to the underlying roofing structure or decking.
