ABSTRACT:
An insulation system for pipes which includes segments of fiberglass insulation or other mineral fiber slit along their length for surrounding the pipe, a butt strip tape for sealing abutting ends of the segments of insulation, and means for sealing a flap on the insulation segment covering the slit after the pipe has been inserted therethrough. The butt strip tape is a laminated tape which includes a layer of paper, a layer of fiberglass, a layer of foil and a pressure sensitive acrylic adhesive. The means for sealing the slit may be either an adhesive film cast on a release liner and applied to the flap or a double sided adhesitve tape. The double sided tape is a laminate which has an adhesive layer on each side of a central, thin substrate. The adhesive used in all instances is an isooctyl acrylate polymer which is approximately a 100% acrylate compound having a solvent content no greater than 0.5%. The adhesive allows the tape to be applied at temperatures ranging frong -17.degree. F. to 158.degree. F.
