The multi-layered facer including a first foil layer, a first paper layer, a glass fabric layer, a second paper layer, and a second foil layer.

Construction boards with foil-containing facers

Embodiments of the present invention are based, at least in part, on the discovery of methods for encapsulating fragile insulation materials within polyisocyanurate foam to thereby provide a construction board having an advantageous balance of insulating properties and mechanical durability.

Process for encapsulating fragile insulation materials within polyisocyanurate

A construction board comprising (i) a foam body having a generally planar shape with first and second planar surfaces, where said foam body is a closed-cell foam body including pentane and a blowing agent additive that has a Hansen Solubility Parameter that is greater than 17 MPacontained within the foam body; and (ii) first and second facers attached to said first and second planar surfaces, respectively.

Isocyanate-based foam construction boards

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 of reroofing, the method comprising of applying to an existing roof surface a membrane composite including a pre-applied adhesive layer by mating the adhesive layer to the existing membrane.

Method of reroofing

A method of continuously manufacturing a cured membrane includes continuously compounding and mixing a vulcanizable rubber composition in a mixing extruder while continuously removing gasses from the vulcanizable rubber composition during mixing with a vacuum. The vulcanizable rubber composition may be continuously extruded to form an extrudate, which may be continuously calendered to form a green membrane. The green membrane may be continuously cured, such as by a hot air conveyor curing system, to form a cured membrane.

System and method for continuously manufacturing cured membranes

A multi-layered thermoplastic roofing membrane comprising a planar body including at least three layers, said at least three layers including (i) a top layer that includes magnesium hydroxide dispersed within a thermoplastic resin, (ii) an upper middle layer disposed below said top layer and including magnesium hydroxide and calcium carbonate dispersed within a thermoplastic resin, and (iii) a lower layer disposed below said upper middle layer and including magnesium hydroxide and calcium carbonate dispersed within a thermoplastic resin.

Polyolefin thermoplastic roofing membranes with improved burn resistivity

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 roof system comprising a roof substrate, a first membrane including first and second opposed planar surfaces, and a second membrane including opposed first and second planar surfaces, where said second membrane is adhered to said roof substrate through an adhesive disposed on said roof-substrate contacting portion of the first membrane, and where said second membrane is adhered to said first membrane through said adhesive disposed on a lap portion of said second membrane.
