JM’s Revolutionary Insulation

Johns Manville has revolutionized the building industry by introducing an entire line of certified Formaldehyde-free™ glasswool building insulation. JM Formaldehyde-free™ insulation provides the same high-quality thermal and acoustical properties as conventional glasswool—just without the formaldehyde-based binder. Why? Because it’s a smart thing to do for our customers and the environment. Formaldehyde has traditionally been used as part of the binder in glasswool insulation. Although there is no health risk with the traditional product, formaldehyde at higher levels may cause irritation and sensitivity.

We pioneered the development of Formaldehyde-free™ fiber glass building insulation over a decade ago and have never stopped looking for new ways to create healthier, more comfortable and energy efficient indoor environments throughout Australia and New Zealand. Our latest is the introduction of a bio-based binder into our proven Formaldehyde-free™ insulation to further demonstrate our belief that, in every detail, materials matter.

Johns Manville unfaced residential and commercial insulation batts is a lightweight thermal and acoustical glasswool insulation made of long, resilient biosoluble glass fibers bonded with a bio-based thermosetting binder. Johns Manville building blanket is a general purpose insulation made without formaldehyde for use in commercial partition and roofing. Roofing blanket is used in most cases under metal roofing of residential and commercial projects meet Basic and BCA requirements and to control condensation, provide thermal and acoustic benefits.
