Characteristics | |
va-Q-vip is an evacuated microporous thermal insulating panel with extremely low thermal conductivity, i.e. excellent insulating properties. The core of va-Q-vip comprises inorganic oxides, up to 80 % being fumed silica and the rest IR opacifiers and a small amount of organic fibres. The core itself is noncombustible, it is sealed in a high gas barrier film under vacuum. The high gas barrier film ensures that the va-Q-vip contains the necessary vacuum level for many years. In general we produce rectangular panels. Due to the special folding technique (va-Q-seam), va-Q-vip have a smooth and rectangular edge. Thus the panels can be put together almost without any gap. Other shapes are possible on demand. |  |
