Foam insulation boards having an improved shiplap edge for interfacing with one another are disclosed.

Insulation boards with interlocking shiplap edges

Thermally laminated foam boards, methods for making thermally laminated foam boards, apparatus for making thermally laminated foam boards, smaller foam pieces made from thermally laminated foam boards, methods for making smaller foam pieces from thermally laminated foam boards, parts made from thermally laminated foam boards, methods for making parts from thermally laminated foam boards, and tools for making parts from thermally laminated foam boards are disclosed. The thermally laminated foam boards are made by thermally bonding at least two polystyrene boards together.

Laminated foam product and methods for making laminated foam products

A structural insulated sheathing including a rigid foam insulation board having a first face, a structural member having a second face, wherein the first face of the foam insulation board is laminated to the second face of the structural member over substantially 100% of the interface between the first face and the second face.

Structural insulated sheathing

A board with preformed seals. In an exemplary embodiment, a sealing material is applied to at least one edge of a board to form a preformed seal on that edge. The board is configured such that when the board is attached to a frame adjacent to a another board, at least a portion of the sealing material applied to the edge of the board seals against at least a portion of an edge another board. In one exemplary embodiment, the boards are configured to seal against edges of substantially identical boards. A plurality of the sheathing boards may be installed on a building frame to form a sheathing system that provides a moisture and/or gas barrier between and interior and exterior of a building.

Board with pre-applied sealing material

Foam board with pre-applied sealing material

A structural panel includes a rigid foam core, a spray foam on an exterior surface of the rigid foam core, and a first outer skin on the spray foam. The rigid foam core includes a tongue portion along a first longitudinal side face and a groove portion along a second longitudinal side face. A second outer skin is also on the spray foam.

Structural panel and method for making same

Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, a polystyrene/polyethylene oxide copolymer, and optionally, an infrared attenuating agent, are provided. In exemplary embodiments, the blowing agent includes at least one hydrofluorocarbon blowing agent. The maleic anhydride-styrene copolymer grafted with polyethylene oxide provides a water vapor permeability of 1.1 perm inch or greater in the extruded foam product without detrimentally affecting physical or thermal properties of the product. Additionally, the copolymer of maleic anhydride-styrene grafted with polyethylene oxide has a positive affect on the processability of the blowing agent(s) in the composition by both widening the process window and enhancing the solubility of the blowing agent in the polymer melt. Thus, the polystyrene/polyethylene oxide copolymer present in the inventive composition acts as a cell enlarger, a plasticizer, and a processing aid. A method of forming an extruded foam product is also provided.

Polystyrene/polyethylene oxide copolymer for enhancing water vapor permeability in thermoplastic foam

Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, an additive blend of polyethylene oxide and a copolymer of polystyrene and maleic anhydride, and optionally, an infrared attenuating agent, are provided. In exemplary embodiments, the polyethylene oxide is ethoxylated polyethylene oxide. Additionally, in at least one embodiment, the blowing agent includes at least one hydrofluorocarbon blowing agent. The blend of ethoxylated polyethylene oxide and copolymer of polystyrene and maleic anhydride provides a water vapor permeability of 1.1 perm inch or greater in the extruded foam product and increases the average cell size of the foam product without detrimentally affecting physical or thermal properties of the product. Additionally, the additive acts as a cell enlarger, a water vapor permeability enhancer, a plasticizer, and a processing aid. A method of forming an extruded foam product is also provided.
