Aluminium high-vacuum coating, AHV for short, applies a wafer-thin layer of aluminium to a fabric. This happens in a chamber with almost no air. The layer has a silver sheen, repels water and oil and reflects heat. The FireMat Silk-A Edition also has such a layer.<\/p>\n\n\n\n

How does aluminium high-vacuum coating work?<\/h2>\n\n\n\n
    \n
  1. First, specialists clean the material so that the aluminium adheres well later.<\/li>\n\n\n\n
  2. Then machines pump almost all the air out of a chamber.<\/li>\n\n\n\n
  3. Next, they heat aluminium until it evaporates. The vapour settles evenly on the fabric.<\/li>\n\n\n\n
  4. Finally, they check that the layer is equally thick everywhere.<\/li>\n<\/ol>\n\n\n\n

    Specialists also call the process vapour deposition. Wikipedia<\/a> explains more.<\/p>\n\n\n\n

    What is the coating used for?<\/h2>\n\n\n\n

    It is found in many everyday items, for example in emergency blankets and food packaging films. On technical fabrics it offers several advantages:<\/p>\n\n\n\n
