A V-grooved composite insulation is provided with an adhesive coating and a protective jacketing material bonded to the adhesive. The protective jacketing material extends beyond the perimeter of the grooved insulation board and comprises at least one intact release layer at a location in which the protective jacketing is clear of contact with the bottom surface of the insulation member and a pressure sensitive adhesive between the portion of the protective jacketing material and the at least one release layer. The method also comprises preshaping the grooved insulation board around a pipe by bending the grooved insulation board, removing the release layer of the protective jacketing material, thereby exposing the pressure sensitive adhesive and securing the pressure sensitive adhesive to the protective jacketing to thereby surround the pipe in a vapor free manner. Grooved insulation boards with protective jacketing so constructed are also provided.

1. A method for installing a V-grooved composite insulation, comprising: providing a grooved insulation board coated with a board adhesive, wherein the adhesive is applied by spraying the board adhesive onto the grooved insulation board and brushing the sprayed grooved insulation board to ensure the entire grooved insulation board is coated with the board adhesive;providing a protective jacketing material that has an inner surface that includes a pre-applied first pressure sensitive adhesive, wherein the first pressure sensitive adhesive is disposed in direct contact with the board adhesive that is coated on the grooved insulation board to bond the protective jacketing material to the grooved insulation board, the pre-applied first pressure sensitive adhesive being separate from the board adhesive coated on the grooved insulation board, wherein substantially the entire surface of the pre-applied first adhesive opposite of the inner surface is in direct contact with substantially the entire surface of the board adhesive opposite of the grooved insulation board, wherein a portion of said protective jacketing material extends beyond the perimeter of the grooved insulation board and includes at least one intact release layer clear of contact with a bottom surface of the grooved insulation board and a second pressure sensitive adhesive between the portion of the protective jacketing material and the at least one release layer, wherein the grooved insulation board includes a plurality of V-grooves defined at spaced intervals in a top surface of the grooved insulation board and extending through the grooved insulation board, but not deep enough to penetrate the protective jacketing the protective jacketing material, each of said plurality of V-grooves being defined by a pair of opposed faces;positioning said grooved insulation board around a pipe by bending the grooved insulation board such that pair of the opposed faces abut one another to define at least one substantially curved portion along the outer surface of the protective jacketing material;removing the at least one release layer thereby exposing the second pressure sensitive adhesive; andsecuring the second pressure sensitive adhesive to the protective jacketing material to thereby surround the pipe in a vapor free manner. 2. The method of claim 1, wherein the grooved insulation board is comprised of mineral wool. 3. The method of claim 1, wherein the grooved insulation board is comprised of two adjacent dissimilar insulating materials. 4. The method of claim 1, wherein the grooved insulation board is comprised of two or more layered, dissimilar insulating materials. 5. The method of claim 1, further including the step of applying an adhesive coating to at least some of said V-grooves on at least one face of said V-grooves. 6. The method of claim 1, further including the step of spacing across and fixedly attaching a plurality of flexible bands to an outer surface of said protective jacketing material, the bands extending beyond the perimeter of said insulation member a length sufficient to permit attachment of the band ends together. 7. The method of claim 6, further including the step of applying an adhesive coating to all of the V-grooves except a center V-groove, the adhesive coating being applied to on one face of the V-groove, thereby forming a hinge at the center V-groove.
