Performance Features

  • Not a Food Source for Pests
  • Mold-Resistant — does not support mold or mildew
  • Formaldehyde-Free™ — promotes better indoor air quality
  • Poly-Encapsulated — wrapped in plastic for cleaner, more comfortable installation with less itch irritation, and dust
  • Thermally Efficient — provides effective resistance to heat or cold transfer with a variety of R-values
  • Acoustically Efficient — reduces sound transmission through floor systems
  • Fire-Resistant and Noncombustible
  • Controls Moisture — the plastic facing is a vapor retarder that resists water vapor transmission. In hot, humid areas, ComfortTherm comes with a perforated plastic facing that does not act as a vapor retarder
  • Noncorrosive — does not promote corrosion of pipes, wiring, or metal studs
  • Damage Resistant — ComfortTherm’s poly sheathing protects it in harsh underfloor environments


ComfortTherm batts cut easily with an ordinary utility knife and are sized to fit standard cavities. The batts are placed between joists and secured with Tiger Teeth (wire hangers) pressed between the floor joists and against the insulation. Once installed, ComfortTherm should be in contact with the subfloor, leaving no gaps. The plastic facing of standard ComfortTherm is a vapor retarder, and in colder climates, is placed toward the heated or conditioned side of the floor. In predominantly hot, humid climates, many codes make vapor retarder use optional. ComfortTherm with a non-vapor retarder facing is available for these areas.

Product Description

ComfortTherm Crawlspace Insulation is a preferred high-permeability product with perforated top and bottom to help prevent moisture accumulation against the subfloor in humid environments (drier climates will get non-perforated vapor retarder product). Each batt is wrapped in a poly film, totally encapsulated with only the ends exposed resulting in easier installation and very little itch or irritation. Additionally, ComfortTherm is formaldehyde-free! Please note that ComfortTherm is NOT a pest control insulation.
