Vacuum insulation article

摘要

A vacuum insulation article is provided which includes a core comprised of multiple plies of glass fibre mats and a vacuum sealed enclosure containing the core. The glass fibres in the mats are highly oriented and have a diameter of less than about 5.0 microns which allows the core to superinsulate at moderate vacuum levels of between about 13.3 Pa and 133.3 Pa (0.1 and 1.0 Torr) as well as in the high vacuum range. The cores may be formed into flat or three-dimensional shapes. The vacuum insulation article is preferably formed by inserting the core into the enclosure, and evacuating and sealing the enclosure.
