Materials Johns Manville makes

17 material categories stocked by commercial suppliers.

TPO Single-Ply Membrane

Thermoplastic polyolefin single-ply roofing membrane installed with heat-welded seams over low-slope roofs. Used on commercial buildings for its reflectivity and resistance to weathering, and applied in mechanically attached, adhered, or ballasted systems.

EPDM Single-Ply Membrane

Ethylene propylene diene monomer single-ply rubber roofing membrane installed on low-slope commercial roofs in ballasted, mechanically fastened, or fully adhered systems. Valued for weathering resistance and long service life on flat and low-slope decks.

PVC Single-Ply Membrane

Heat-weldable thermoplastic single-ply roofing membrane made of polyvinyl chloride, offering chemical and fire resistance. Used on commercial low-slope roofs, particularly where grease or chemical exposure is a concern.

Modified Bitumen Membrane

Modified bitumen membrane is a factory-fabricated asphalt-based roofing sheet reinforced with polyester or fiberglass, applied by torch, cold adhesive, hot asphalt, or self-adhesion. It is used in commercial construction on low-slope roofs, typically in multi-ply systems.

Built-Up Roofing (BUR)

A low-slope roofing system constructed from alternating layers of bitumen and reinforcing ply felts, typically finished with a gravel or mineral surfacing. Used on commercial and industrial buildings to provide a durable, multi-ply waterproof membrane.

Polyiso Roof Insulation

Rigid polyisocyanurate foam board with facers, providing high thermal resistance per unit thickness for low-slope roofing. Installed over roof decks in commercial systems as continuous insulation and tapered assemblies for drainage.

Roof Cover Board

Roof cover board is a rigid substrate installed over insulation to provide a durable surface for membrane attachment and resistance to impact, fire, and wind uplift. It is used in commercial low-slope roofing assemblies beneath single-ply and modified bitumen membranes.

Roofing Fasteners & Plates

Screws, nails, and stress-distribution plates used to secure insulation, membrane, and cover boards to roof decks. Selected by deck type and pull-out resistance for mechanically attached commercial roofing systems.

Fiberglass Batt Insulation

Preformed blanket insulation made of spun glass fibers, sized to fit between wall studs, floor joists, and ceiling framing. Used for thermal and acoustic insulation in commercial wall and ceiling assemblies, available faced or unfaced.

Mineral Wool Batt Insulation

Mineral wool batt insulation is a semi-rigid fibrous product made from stone or slag, installed in wall and floor/ceiling cavities for thermal and acoustic performance. It is noncombustible and used in commercial construction for fire-rated assemblies, sound control, and continuous insulation applications.

Polyiso Rigid Board Insulation

Rigid polyisocyanurate foam board with facers, providing high thermal resistance per inch. Used as continuous insulation in commercial roofing assemblies and wall systems to meet energy performance requirements.

Spray Polyurethane Foam

Two-component polyurethane foam applied on site that expands and cures in place to provide insulation and air sealing, available in open-cell and closed-cell formulations. Used in commercial walls, roofs, and cavities for thermal resistance and air barrier continuity.

Mechanical & Pipe Insulation

Preformed fiberglass, mineral wool, or elastomeric insulation applied to piping, ducts, and equipment. Used in commercial mechanical systems to control heat loss and gain, prevent condensation, and meet energy code requirements.

Acoustic & Thermal Partition Insulation

Mineral wool or fiberglass batt insulation installed within interior partition wall cavities to reduce sound transmission and provide thermal resistance. Commonly specified in commercial interiors to meet STC acoustic ratings between office, tenant, and demising walls.

Pipe Insulation

Thermal insulation applied to piping to limit heat loss or gain, control condensation, and provide freeze and personnel protection. Available in fiberglass, elastomeric, mineral wool, and cellular glass forms for commercial mechanical and plumbing systems.

Acoustic / Sound Insulation

Acoustic insulation is a fibrous or foam material installed in wall cavities, floor/ceiling assemblies, and around ductwork to reduce airborne and structure-borne sound transmission. It is used in commercial construction to improve STC ratings in partitions between offices, hotel rooms, multifamily units, and mechanical spaces.

Roof Flashing

Sheet-metal or membrane components installed at roof transitions, penetrations, and edges to direct water away from joints. Used in commercial roofing to seal parapets, curbs, valleys, and terminations against leakage.
