ComfortTherm insulation is wrapped in plastic for dust-free, itch-free installation and can be used in a wide variety of wood frame, engineered wood and steel frame construction applications, including new construction and retrofit.

FSK-25 Batts

Johns Manville Formaldehyde-free FSK-25 thermal and acoustical fiberglass insulation is available in R-values up to R-30 and is offered in precut batts to fit standard wall cavities. FSK-25 faced batts combine fire resistance with excellent vapor resistance and can be used in a wide variety of wood frame, engineered wood and steel frame construction applications, including new construction and retrofit. FSK-25 batts are designed with a foil facer that can be left exposed where codes permit.

Unfaced Fiberglass

Johns Manville Formaldehyde-free unfaced thermal and acoustical insulation offers R-values of up to R-49. It is offered in precut batts to fit standard wall cavities or rolls for custom installation in any sized cavity. Unfaced insulation reduces sound transmission through walls, ceilings and floors and can be used in a variety of wood frame, engineered wood and steel frame construction applications, including new construction and retrofit.

Climate Pro® Blow-In

Johns Manville Climate Pro Formaldehyde-free blow-in fiberglass insulation offers thermal and sound control, along with fire-resistance. One bag of Climate Pro provides 73 square feet of R-30 coverage. Engineered for professional use with high-volume blowing machines, it’s ideal for attics, nonconforming spaces and hard-to-reach areas, making the job faster and easier.

AP™ Foil-Faced Polyisocyanurate Continuous Insulation

Johns Manville AP Foil-Faced Polyiso Continuous Insulation board consists of a uniform closed-cell polyisocyanurate foam core bonded on each side to a foil facer. One side has a reflective foil facer, and the other side has a white, non-reflective foil facer to suit your building needs. Polyiso provides one of the highest R-values per inch of any rigid insulation (R-6.0 at 1 inch). Furthermore, when properly installed, AP Foil-Faced Polyiso Continuous Insulation functions as a water-resistive barrier, vapor barrier and air barrier, eliminating the need to install additional components.

Curtainwall

Johns Manville Curtainwall insulation is available in a wide range of thicknesses and is available plain or with a foil facing vapor retarder. Providing superior fire resistance and acoustical properties, Curtainwall is designed for use in glass, metal and masonry curtain wall spandrel systems and can be placed between or over framing members.

Safing

Johns Manville Safing is available plain or with a foil facing vapor retarder on one face. Nonorganic and moisture-resistant, Safing prevents smoke and flames from passing through openings in fire-rated assemblies. It is designed to provide a fire-rated seal when installed between the spandrel panel and floor slab in commercial curtain wall systems.

Sound Attenuation Fire Batt (SAFB)

Johns Manville Sound Attenuation Fire Batt (SAFB) insulation is manufactured from inorganic fibers derived from volcanic rock. Noncombustible and moisture-resistant, the lightweight and flexible batts are designed to deliver excellent noise control in metal stud wall cavities of interior partitions, exterior walls and above suspended ceiling systems. As excellent sound absorbers, this batt insulation improves the wall assembly Sound Transmission Class (STC) ratings by up to 10dB.

JM CladStone™  Water & Fire Block Mineral Wool

Johns Manville CladStone Water & Fire Block insulation is manufactured from inorganic fibers that are derived from volcanic rock. Advanced manufacturing technology ensures consistent product quality with high-fiber density and low shot content for excellent performance. It is noncombustible with water-repellent properties, making it ideal for wall cavity and rainscreen applications. It is available in two densities, CladStone 45 (4.5 pcf) and CladStone 60 (6.0 pcf).
