Vacuum insulation panels

Two notable methods to produce microcellular foams include gas supersaturation in combination with an extrusion process developed by MIT/Trexel [84-86] and the continuous extrusion process by Dow [87,88]. Super-insulating materials are made by the encapsulation of a filler material inside a barrier film, aluminum foil, or metallized film. These materials exhibit 5-7 times the R-value of typical nonvacuum insulating materials depending on vacuum level and barrier and filler type. Uses for these VIPs (vacuum insulation panels) include refrigeration and controlled-temperature shipping containers. 

Recent Developments in Open Cell Polyurethane-Filled Vacuum Insulated Panels for Super Insulation Applications... 

Vacuum Insulated Panels (VIP), having a thermal conductivity three to five times lower than conventional PU foams, allow the achievement of superior insulation performance. They can be used to partially replace the conventional insulation materials to provide a more efficient insulation structure, which allows energy saving without the need to increase the insulation thickness. Alternatively, VIP can be used in those applications where it is important to reduce the insulation thickness to a minimum value without loosing thermal performances.

Vacuum insulation panels age with time. As the pressure inside the evacuated element rises because of envelope permeability, so does the thermal conductivity of the assembly. Equivalent conductivity values of 30-year aged VIPs depend strongly on the product and materials used and are typically on...
