Abstract: 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 reinforce-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.

Abstract: A panel is configured for attachment to a mounting surface of a building structure. The panel includes a first end surface and a second end surface, spaced from each other along a longitudinal axis; a top edge surface and a bottom edge surface, spaced from each other and offset from the longitudinal axis; and an inner surface and an outer surface, opposed to each other and extending from the first end surface and the second end surface. The inner surface includes a contact portion and a contour portion. The contact portion is disposed on a reference plane. The contour portion is contoured toward the outer surface, away from the reference plane, such that the contour portion defines a channel. The channel extends along at least a portion of a length of the panel, between the first end surface and the second end surface.

Abstract: Polyurethane foams and methods of manufacturing are described herein. The foam can include (a) a polyurethane formed by the reaction of (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, and (ii) one or more polyols; and (b) a filler. The amount of filler in the foam can be from 50 to 90% by weight, based on the total weight of the foam. The filler can include a plurality of fibers and/or a particulate filler. The polyurethane foams described herein are made without adding a surfactant to the reaction mixture. The density of the polyurethane foam can be at least 5 lb/ft3.
