A spacer is used in IGU’s to physically separate the individual glass panes. Spacer can be of different material such as for example:

  • Metal spacers out of aluminum or stainless steel
  • Carbon based spacers either rigid or flexible
  • TPS (Thermoplastic spacer): a gel like liquid that is formed to spacer size when applied to the glass.
  • Other (e.g. elastic spacer)
