Hi-Temp Pumice Flue Liner


RCP Hi-Temp Pumice Flue Liners out-perform other flue liners in any comparison you care to make. These flue liners weigh considerably less than clay (1/3 less on a per foot basis). This aspect will lead to faster finishing and easier handling.

Hi-Temp Pumice Flue Liners also have the physical characteristics that make them the superior choice for fireplaces. They have exceptional resistance to thermal shock and extremely low thermal conductivity. They offer good resistance to acids and other flue gases. They cause little soot build-up since the inside surface heats and cools quickly.

  •  A superior choice for fireplaces 
  • Out-perform other flu liners in any comparison you can make
  • 1/3 less weight than clay flue liners
