Johns Manville Fiberglass Batts


JM Formaldehyde Free™ Fiberglass building insulation offers superior thermal and acoustical performance - and it improves indoor air quality because it's made without formaldehyde.


Product Description: Johns Manville unfaced insulation is a lightweight thermal and acoustical fiber glass insulation made of long, resilient glass fibers bonded with an acrylic thermosetting binder. Where vapor control is required, a separate vapor retainer can be used.


Performance Advantage:

• Improves indoor air quality - because it’s made without formaldehyde.

• Thermally efficient - provides effective resistance to heat transfer with R-values up to R-38 (RSI-6.7).

• Controls sound - reduces transmission of sound through exterior and interior walls and floor/ceiling assemblies.

• Fire-resistant and noncombustible - see Specification Compliance.

• Noncorrosive - does not accelerate corrosion of pipes, wiring or metal studs.
