Choosing Pumped Masonry Versus Stainless Steel Liners

Pumped Masonry
Stainless Steel
  • Is centered in the flue to assure complete coverage throughout the chimney.
  • Is very difficult to center in the flue, resulting in areas with little or no insulating protection.
  • Provides structural strength to deteriorated or cracked casings, fills open joints, seals crumbling mortar.
  • Provides no significant structural strength to the casing.
  • Golden flue installers line fireplace smoke chambers, protecting the flue for its entire length.
  • Stainless steel liners do not extend into the smoke chamber; often do not directly connect to the stove.
  • Masonry liners experience minimal expansion and contraction from flue heat.
  • Stainless steel expands and contracts dramatically, often stressing casing and tearing insulation.
  • Golden Flue masonry liners have been tested by Underwriter's laboratories and Warnock Hershey to withstand temperatures in excess of 2100 degrees.
  • Stainless steel, subjected to the heat of a chimney fire, loses its "stainless" properties, opening the door to rust and corrosion.
  • Golden Flue is the only lining system tested and approved for safety after multiple chimney fires.
  • Building code requires that any metal components in a chimney be inspected after a fire for possible replacement.
  • Pumped masonry is certified for use with all fuels: oil, gas, wood, coal.
  • Different grades of stainless steel and aluminum must be used for different fuels. A future change in fuel may require a relining.
