ADHESIVE-BACKED COMPOSITE INSULATION BOARDS WITH VACUUM-INSULATED CAPSULES
A method of constructing a roof assembly, the method comprising (i) mechanically affixing a construction board to a roof deck; (ii) providing a composite insulation board including (a) at least one vacuum-insulated capsule; (b) a foam body that encases said at least one vacuum-insulated capsule, said foam body having first and second opposed planar surfaces; (c) a layer of pressure-sensitive adhesive disposed, either directly or indirectly, on one of said first and second opposed planar surfaces; and (d) a release liner removably attached to the layer of pressure-sensitive adhesive; (iii) removing the release liner from the composite insulation board; (iv) mating the composite insulation board to the construction board that is mechanically affixed to the roof deck; and (v) installing a membrane system over the composite insulation board.
1 . A method of constructing a roof assembly, the method comprising:
i. mechanically affixing a construction board to a roof deck;
ii. providing a composite insulation board including:
(a) at least one vacuum-insulated capsule;
(b) a foam body that encases said at least one vacuum-insulated capsule, said foam body having first and second opposed planar surfaces;
(c) a layer of pressure-sensitive adhesive disposed, either directly or indirectly, on one of said first and second opposed planar surfaces; and
(d) a release liner removably attached to the layer of pressure-sensitive adhesive;
iii. removing the release liner from the composite insulation board;
iv. mating the composite insulation board to the construction board that is mechanically affixed to the roof deck; and
v. installing a membrane system over the composite insulation board.
2 . The method of claim 1 , further comprising the step of providing a membrane carrying a factory-applied adhesive system and a release liner removably attached over the adhesive system, where said step of installing includes removing the release liner from the membrane and mating the membrane to the composite insulation board.
3 . The method of claim 1 , further comprising the step of installing a coverboard over the composite insulation board.
4 . The method of claim 1 , where the pressure-sensitive adhesive is a UV-cured adhesive layer.
5 . The method of claim 1 , wherein said composite insulation board further includes a first facer secured to said first opposed planar surface and a second facer secured to said second opposed planar surface and wherein said layer of pressure-sensitive adhesive is disposed on said second facer.
6 . The method of claim 5 , wherein said composite insulation board has a thickness of from about 0.25 inches to about 12 inches.
7 . The method of claim 1 , wherein said foam body includes an insulating foam selected from polyurethane or polyisocyanurate.
8 . The method of claim 7 , wherein said step of providing a composite insulation board includes manufacturing the insulating foam by mixing a first stream that includes an isocyanate-containing compound with a second stream that includes an isocyanate-reactive compound.
9 . The method of claim 1 , wherein said foam body completely encases said at least one vacuum-insulated capsule.
10 . The method of claim 1 , wherein said foam body partially encases said at least one vacuum-insulated capsule.
11 . The method of claim 1 , wherein said step of providing a composite insulation board includes manufacturing the at least one vacuum-insulated capsule by providing a core material, surrounding the core material with a membrane material to form a chamber, and evacuating air from the chamber to form the at least one vacuum-insulated capsule.
