Octopus Furnaces & Duct Work

Older octopus furnaces &  ductwork, especially those installed before the mid-20th century, often contain asbestos materials. The type of asbestos used in these systems can vary, but the most common types found in heating systems, including furnaces and ductwork, are:

  1. Chrysotile (White Asbestos): Chrysotile is the most common type of asbestos and was widely used in various construction materials, including insulation around heating systems.  Its flexible and heat-resistant properties made it suitable for insulating pipes, furnaces and ductwork.
  2. Amosite (Brown Asbestos): Amosite was also used in some heating system insulation.  It has shorter, brittle fibers compared to chrysotile and was known for its durabilityand resistance to high temperatures.
  3. Crocidolite (Blue Asbestos): While less common, crocidolite was occasionally used in specific insulation products for its heat resistance.

Asbestos-Containing Heating systems


The use of asbestos in heating systems was prevalent until the late 20th century when the health risks associated with asbestos exposure became more widely recognized. If you are dealing with an older heating system, especially one that predates the 1980’s, it is prudent to assume that asbestos-containing materials may be present. 

Handling or disturbing asbestos-containing materials, including those in old furnaces and ductwork, without proper precautions can lead to the release of airborne fibers,  and can pose serious health risks.  Always follow safety guidelines and local regulations when dealing with potential asbestos-containing materials and how to safely remove and dispose of this material.
