Insulation is a barrier material to resist/reduce substance (water, vapor, etc. ) /energy (sound, heat, electric, etc.) to transfer from one side to another. Heat/ Thermal Insulation is a barrier material to resist / block / reflect the heat energy (either one or more of the Conduction, Convection or Radiation) to transfer from one side to another.
Cork, plywood, hardboard, drywall, and foam insulation are common alternatives to Homasote. Homasote is used for blocking knit or crochet pieces. "Homosote (sic) is sturdy, and incredibly absorbent. It will wick water away from your garment so it dries more quickly. And it's like a bulletin board—you can stick pins in it easily." [10]
Common products such as paint, insulation, rigid foam, particle board, plywood, duct liners, exhaust fumes and other chemical contaminants from indoor or outdoor sources, and biological contaminants can be trapped inside by the HVAC AC system. As this air is recycled using fan coils the overall oxygenation ratio drops and becomes harmful.

Spray foam insulation has been used to stop heat escaping from roofs, lofts and attics for decades and comes in two forms. Closed cell spray foam is rigid once set. It is a better thermal ...
The generalised chemical structure of polyisocyanurate showing the isocyanurate group. The polyols are abbreviated as R-groups.. Polyisocyanurate (/ ˌ p ɒ l ɪ ˌ aɪ s oʊ s aɪ ˈ æ nj ʊər eɪ t /), also referred to as PIR, polyol, or ISO, is a thermoset plastic [1] typically produced as a foam and used as rigid thermal insulation.
The foam is typically used for preventing leaks, filling gaps during construction and holding items in place. The items are typically stronger than human hair, though.
A cancer syndrome or family cancer syndrome is a genetic disorder in which inherited genetic mutations in one or more genes predisposes the affected individuals to the development of cancers and may also cause the early onset of these cancers. Although cancer syndromes exhibit an increased risk of cancer, the risk varies.
