Composite panels and methods of preparation are described herein. In some embodiments, the composite panel can include a first fiber reinforcement, a polyurethane composite having a first surface and a second surface opposite the first surface, wherein the first surface is in contact with the first fiber reinforcement; and a cementitious material adjacent the first fiber reinforcement opposite the polyurethane composite. The polyurethane composite can be formed from (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, (ii) one or more polyols, and (iii) a particulate filler. The fiber reinforcement can be formed from a woven or non-woven material, such as glass fibers. The composite panel can further include a material, such as a second fiber reinforcement and a cementitious layer, in contact with the second surface of the polyurethane composite. Articles comprising the composite panels are also disclosed.

One aspect of the disclosure is roofing shingle including a shim layer having a top surface, a first side edge, and a second side edge positioned opposite the first side edge. The roofing shingle also includes a top shingle layer at least partially laminated to the top surface of the shim layer, where the top shingle layer includes a first side edge offset a sidelap distance from the first side edge of the shim layer such that a side portion of the top surface of the shim layer is exposed, and a second side edge extending beyond the second side edge of the shim layer so as to overlap the second side edge of the shim layer by the sidelap distance.

A composite board comprising (i) a first foam region; (ii) at least one fragile insulating material; and (iii) a second foam region, where said second foam region is substantially devoid of hydrocarbons.

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.

A resin composition includes: a copolymer including a fluoroolefin unit and a monomer unit having a hydroxy group; and an esterified cellulose resin; in which the amount of the esterified cellulose resin is from 0.2 to 9 parts by mass with respect to 100 parts by mass of the copolymer including a fluoroolefin unit and a monomer unit having a hydroxy group. A layered body includes a coating film formed from the resin composition.

Roof covering (I) for flat roofs, comprises (A) a polymeric sealing layer and (C) a self-adhesive layer, separated by a soft elastomeric intermediate layer (B).

A dual-reinforced construction board is disclosed comprising a core having an upper surface and an opposing lower surface, a first reinforced fibrous facer adhered to the upper surface of the core and a second fibrous facer adhered to the lower surface of the core. Each of the first and second fibrous facer comprise a non-woven mat coated on a first surface with a coating composition. The first fibrous facer and optionally the second fibrous facer further include a reinforcement layer adhered to at least a portion of the first surface of the non-woven mat. The dual-reinforced construction board has a fastener pull-through strength of at least 400 lbf.

A fiber-reinforced resin composite sheet of the present invention contains: a polyamide resin film containing a dicarboxylic acid component (a) and a diamine component (b); and a plurality of reinforcing fibers laminated in a state of being oriented in the same direction on the polyamide resin film, the reinforcing fibers being obtained by opening a reinforcing fiber bundle. The dicarboxylic acid component (a) contains 60 mol % or more and 100 mol % or less of terephthalic acid. The diamine component (b) contains 60 mol % or more and 100 mol % or less of 1,9-nonanediamine and 2-methyl-1,8 octanediamine. The fiber-reinforced resin composite sheet has a volume content rate Vf of the reinforcing fibers of 20% or more and 70% or less and a thickness of 20 μm or more and 70 μm or less.

Some embodiments relate to a roofing material. The roofing material may comprise, consist of, or consist essentially of a substrate and a coating on the substrate. In some embodiments, the coating may comprise, consist of, or consist essentially of a polymer blend and at least one filler. In some embodiments, the polymer blend may comprise, consist of, or consist essentially of at least one hydrocarbon oil, at least one resin, at least one polymer, or any combination thereof. In some embodiments, the at least one hydrocarbon oil, the at least one resin, the at least one polymer, or any combination thereof may be present in an amount or in amounts sufficient to result in the polymer blend or the coating having a select softening point, a select viscosity, or any combination thereof.
