Title: Development and thermal performance verification of composite insulation boards containing foam-encapsulated vacuum insulation panels

High-performance thermal insulation is a critical need for buildings. This article presents the development and thermal characterization of composite foam insulation boards containing low-cost vacuum insulation cores. The composite foam-vacuum insulation boards were created in a semi-automatic operation in a foam insulation manufacturing plant. The low-cost vacuum insulation is a new technology called modified atmosphere insulation. The production process of modified atmosphere insulation is much simpler than traditional vacuum insulation manufacturing, and it has the potential for significant cost reduction at the same thermal performance. Prototypes of small- and full-scale composite insulation boards were created for testing and evaluation under laboratory and natural weatherization conditions. The laboratory tests showed that the overall thermal resistance of the composite insulation board is at least twice that of current rigid foam insulation used in building envelope. Lastly, ongoing test of the composite insulation in a natural exposure test facility indicates that the high thermal performance was retained through handling and installation as well as natural aging over a period of one and a half years.
