TOPVQ® GFB-C Vacuum Insulation Panel (VIP) is an ultra-thin thermal insulation material with extremely low thermal conductivity basing on the chopped glass fibers. Under the same thickness, the thermal insulation effect of vacuum insulation board is 5-10 times higher than that of traditional thermal insulation materials. It is an excellent choice for the thermal insulation needs of construction, refrigeration, cold chain, medical package, household appliances, and other industries.
