Perlite heat insulation
- the ideal heat insulator
A huge advance in coldroom technology
The mineral perlite forms the base material for a production process developed and patented by Viessmann which, for the very first time, enables the manufacture of heat insulating plates.
Perlite forms an ideal insulation medium for floors, walls and ceilings in refrigeration and cleanroom technology - the first choice in building areas where no additional fire load my be introduced.

Perlite advantages
Not only does it offer good heat insulation, it does not burn, is chemically clean and resistant to fungi. It is unaffected by acids or alkalis, and with oils and grease. It contains no fibreas of any kind and there are no health hazards in its processing. It is ecologically safe and recyclable.
