Prefabricated composite insulation board

摘要

A prefabricated composite insulation board comprises a facing of a flexible sheet material and a plurality of vacuum insulation panels (VIP) adhesive bonded thereto. A body of insulating foam overlies the vacuum insulating panels and the carrier. There are gaps between adjacent vacuum insulation panels and these gaps are filled with the foam. Alternatively, groups of VIP's may be positioned close to one another and gaps left at defined locations. These gaps may be used to provide regions at which the panel may be cut to a desired length without cutting through and VIP's. External markings such as cut-lines may be provided to indicated the location of these gaps.

主权项

1. A method for manufacturing an insulating panel comprising the steps of:
providing a first facer, wherein the facer comprises a laminate; adhesively bonding a plurality of separate vacuum insulation panels to the facer, at least some of the vacuum insulation panels being spaced-apart on the facer to define gaps therebetween, wherein the adhesive is a layer of the facer to which the separate vacuum insulation panels are directly attached, and wherein the adhesive is activated prior to attachment of the vacuum insulation panels; leading the facer with the vacuum insulation panels bonded thereto to a lay-down station; laying down liquid foam reactants over the vacuum insulation panels; and allowing the foam to expand to form an insulating body.
