An asphaltic sheet comprising an asphaltic component including an asphalt binder and expandable graphite.

Asphaltic sheet materials including expandable graphite

A roof assembly comprising: a roof deck; a thermoplastic membrane covering the deck; and a fabric having disposed thereon expandable graphite.

Fire-resistant roof system and membrane composite

A method for preparing a roofing membrane in the form of a roll, comprising the steps of: providing a polymeric membrane; providing a fabric having a coating disposed thereon; attaching the polymeric membrane to the fabric to form a composite; and rolling the composite. Wherein the coating includes expandable graphite dispersed within a binder.

Coated fabrics including expandable graphite

A multi-layered membrane comprising a first thermoplastic layer and a second thermoplastic layer, where the second layer includes expandable graphite.

Thermoplastic membranes containing expandable graphite

A thermoplastic membrane composite comprising (i) a planar thermoplastic body having first and second opposed planar surfaces; (ii) a fabric backing fixedly attached to said first planar surface thereby forming an interface between said thermoplastic body and said fabric backing; and (iii) expandable graphite disposed at or near the interface.

Fire-resistant thermoplastic membrane composite and method of manufacturing the same

A method for producing an asphaltic sheet, the method comprising of providing an asphaltic sheet; and applying expandable graphite particles to the asphaltic sheet.

A method of preparing a seamless membrane over a flat or low-sloped roof, the method comprising applying multiple layers of a liquid coating composition over a roof surface, where said step of applying includes applying at least one layer of a liquid coating composition that includes expandable graphite.

Liquid coatings including expandable graphite

A multi-layered membrane comprising a first thermoplastic first layer and a second thermoplastic layer, where the second layer includes expandable graphite.

A roofing membrane comprising at least one layer of a cured rubber and expandable graphite dispersed within the cured rubber.

Roofing membranes with expandable graphite as flame retardant

A roofing article comprising (i) an asphaltic substrate; and (ii) a plurality of mullite-containing granules disposed on a surface of the substrate, where said mullite-containing granules include a mullite concentration of at least 35 wt % and at most 63 wt % as determined by quantitative x-ray diffraction.

Asphaltic membrane with mullite-containing granules

A building material comprising a substrate layer and a pressure-sensitive adhesive layer, where the pressure-sensitive adhesive layer includes expandable graphite.

Pressure-sensitive adhesives including expandable graphite

A method of preparing an EPDM roofing membrane panel, the method comprising preparing a vulcanizable composition including expandable graphite by mixing an EPDM rubber and expandable graphite, forming a sheet from said vulcanizable composition, preparing a green membrane panel using said sheet, and curing said green membrane panel to form the EPDM roofing membrane panel, where said steps of preparing a vulcanizable composition, said step of forming a sheet, said step of preparing a green membrane, an said step of curing each include a peak temperature at which each of said steps respectively take place, and where the expandable graphite has an onset temperature above said peak temperature of each respective step.
