This Small Business Innovation Research Phase I project will develop an ultra-thin high-R-value robust vacuum insulation panel (VIP). Thermal models indicate that with a ½" thick VIP an R-value of 50 can be achieved with an expected retail cost of ~$4.25/ft2. The technology uses tensile structural elements as thermal impedances and is based on a pending patent which has been licensed from the University of Illinois at Chicago. The VIP is expected to be suitable for installation in industrial and residential structures since it has a stainless steel foil exterior as opposed to current VIP technology, which uses a laminate of polyester and aluminum foil as its vacuum barrier. The aluminum foil creates a thermal short (edge losses) around the current VIPs which can greatly reduce their effective R-value. The use of stainless steel has the additional advantage of significantly reducing edge losses as well as increased puncture resistance. The broader impact/commercial potential of this project will be a drastic reduction in the energy required to heat and cool dwellings, or to refrigerate trucks used to transport perishable goods. In transportation, a refrigerated hi-cube trailer with 3? of polyurethane foam has an R-value of ~19, and could gain 9% more volume and carry 860 pounds less weight when using a ½" thick VIP with an R-value of 50. Most refrigerated trailers in the US consume up to 1.1 gallons of diesel fuel each hour to keep their loads cold. Since there are ~330,000 refrigerated trailers operating for ~3,000 hours/year, this translates into a fuel savings of 62%, or nearly 2% of the total diesel fuel consumption in this country each year. Compact and inexpensive thermal insulation can make better use of space inside new dwellings, and be used to retrofit existing dwellings with higher R-value insulation. In a 2002 review of VIPs for the residential market prepared by NAHB Research Center for the US Department of Housing and Urban Development Office, low puncture resistance was cited as a key factor slowing the adoption of vacuum insulation panels.

这个小企业创新研究第一阶段项目将开发超薄高r值坚固真空隔热板（VIP）。热模型表明，对于1 / 2英寸厚的VIP， r值为50，预期零售成本约为4.25美元/平方英尺。该技术使用拉伸结构元件作为热阻抗，基于一项正在申请中的专利，该专利已获得芝加哥伊利诺伊大学的许可。与目前使用聚酯和铝箔层压作为真空屏障的VIP技术不同，VIP的外部是不锈钢箔，因此预计适合安装在工业和住宅建筑中。铝箔在当前vip周围产生热短（边缘损耗），这可以大大降低其有效r值。使用不锈钢具有显著减少边缘损失以及增加抗穿刺的额外优势。这个项目更广泛的影响/商业潜力将是大大减少住宅供暖和制冷或用于运输易腐货物的冷藏卡车所需的能源。在运输方面，一辆装有3？聚氨酯泡沫的r值为19，当使用r值为50的1 / 2英寸厚的VIP时，可以增加9%的体积，减少860磅的重量。在美国，大多数冷藏拖车每小时消耗高达1.1加仑的柴油来保持货物的低温。由于每年约有33万辆冷藏拖车运行约3000小时，这意味着每年节省62%的燃料，或占该国柴油总消耗量的近2%。紧凑和廉价的隔热材料可以更好地利用新住宅内部的空间，并用于改造具有更高r值隔热材料的现有住宅。在2002年由NAHB研究中心为美国住房和城市发展部准备的住宅市场vip审查中，低穿刺阻力被认为是减缓真空隔热板采用的关键因素。
