Abstract
Insulating the building envelope is a key strategic goal in the effort to reduce energy use in buildings. Most early buildings used no thermal insulation. Over the years traditional cellulose based materials have given way to mineral fiber insulation materials. Now a variety of foam plastic materials are used on their own or in conjunction with mineral fiber insulations. The most efficient foam plastic insulations are closed cell products containing low thermal conductivity gases. Unfortunately, many of those gases have been identified as ozone depleting substances or with relatively high global warming potential. These characteristics have resulted in current or potential future regulation of their supply and use. Creating super-insulating products that incorporte the benefit of laminated panel products with the thermal efficiency and benign environmental effects of vacuum panels is a possiblity. Using the installed capacity of closed cell boardstock plants to make a hybrid panel means a more rapid market entry. Discussion will focus on the general features of the existing plants but alos cover aspects of vacuum panel incorporation, installation in the field, and problems relating to product durability.
