JM Formaldehyde-free™ Insulation

Fiber glass insulation is made of two things; glass and a binder. The binder glues the thin glass threads together. This is “bonded” fiber glass insulation, found in batts and rolls. Johns Manville Formaldehyde-free fiber glass insulation utilizes a bio-based binder that eliminates binder-related formaldehyde emissions. Other manufacturers may use formaldehyde in their binder. 

Performance Advantages:

  • Formaldehyde Free: will not off-gas formaldehyde in the indoor environment.
  • Thermal Efficiency: provides effective resistance to heat transfer.
  • Sound Control: reduces transmission of sound through roofs and walls of metal buildings.
  • Noncorrosive: does not accelerate corrosion of metal studs, pipes or wiring.
  • Durable: will not rot, mildew or otherwise deteriorate.
  • Resilient: bonded glass fibers will not pull apart during normal applications and resist settling, breakdown and sagging from vibration.
  • Flexible: forms readily around corners and curved surfaces.

The U.S. Environmental Protection Agency recommends limiting exporsure to formaldehyde as much as possible.

Unfaced, Unlaminated Fiber Glass

The Simple Saver System® utilizes it's fabric liner as a continuous vapor retarder and requires unfaced and unlaminated fiber glass. This is an inherit difference between the Simple Saver System and “traditional” metal building insulation which has a laminated facing glued directly to the insulation.

Request Thermal Design to ship JM Formaldehyde-free fiber glass insulation directly to the job site. Insulation rolls are carefully packaged for savings in freight, ease of handling, protection of quality and have excellent recovery once opened on site.
