A segmented insulative device and related kit for insulating components of a thermal distribution system, and particularly chilled fluid systems. The kit includes a sheet of segmented insulation formed by a composite layer of segmented, flexible, pre-sewn insulation that is easily cut to size in the field using scissors, utility knives or other simple, hand-held cutting devices. The composite layer includes at least one outer layer of low permeance laminate devoid of stitching and adhered to the pre-sewn insulation. The kit also includes low permeance pressure-sensitive adhesive tape as fasteners, also easily cut to length, using hand-held devices. The low permeance laminate and the low permeance pressure-sensitive adhesive tape form a contiguous outer water vapor barrier free of stitching that would otherwise compromise low permeance. The segmented insulation and the fasteners are attached to one another in the field. This provides an installation kit that an installer can use to provide a versatile insulation in the form of the assembled segmented insulative device that insulates against heat gain to the chilled surface and retards the intrusion of water vapor into the insulation as well as to the chilled surface. The segmented insulative device lends itself to quick customization on-site rather than requiring costly off-site manufacture or pre-assembly and subsequent quick installation on the pipe component requiring thermal installation.
