WhatsApp: +86 18221755073The reason perlite insulation is technically referred to as "expanded perlite" is because when it is heated during the manufacturing process (to approximately 1600°F/900°C) the moisture expands, causing it to pop like popcorn at 1600°F. This makes perlite a very low-density material that is light-weight, with low thermal conductivity values.
