Aluminium foil coated high silica cloth is coating on silica cloth which is with acid treatment and calcination with the silver color aluminium foil coating. High silica cloth is made of fiber glass cloth and it has more than 96% SiO2 because of the post treatment. Meanwhile the melting point of this silica cloth is also higher a lot than before by acid treatment and calcination. 600gsm high silica cloth can be used below 800℃ continuously. However, it can be used under 1200℃ in short time. The aluminium foil coating can withstand 260 to 300℃. Except for fire resistance, the coating can also reflect most heat. It is an ideal material for heat insulation.
The base fabric is 600g/m2 high silica cloth. Including silver coating 100g/m2 on its single side, total weight per square meter will be 700g. Then final thickness is 0.8mm. Yarn count per centimeters is 18/13. High silica cloth is woven in 8 harness satin weaving. In this pattern, there is a weft yarn floats over seven warp yarns and under one warp. In fact satin weave is a very stable weave.
