Characteristics | |
Since the thermal conductivity of VIPs produced by va-Q-tec is of the order of one tenth of the conductivity of conventional insulation materials there is greater opportunity to rationalise a space saving design. va-Q-mic is an evacuated thermal insulating panel with extremely low thermal conductivity. The core of va-Q-mic comprises an open cell micro fleece. The micro fleece core is sealed in a ultra low permeation gas barrier film under vacuum. The barrier film ensures that the va-Q-mic contains the necessary vacuum level for a long time. In general, rectangular panels are produced. Other shapes are available on request. |  |
Applications | |
va-Q-mic is especially developed for applications in a cool environment, when extremely little space is available. The lifetime of va-Q-mic depends very much on environmental conditions e.g. temperature and humidity. Please discuss your application with va-Q-tec AG. |  |
