Abstract
Abstract A panel for providing walls, roofs and floors with thermal insulation and fire retardance includes at least two essentially parallel face members separated to form a space between the face members and urethane within the space to provide the thermal insulation and fire retardance. The panel may additionally include frame members extending between the face members for providing support and for enclosing the urethane. At least one of the frame members has at least one port through which urethane foam can enter between the face members. A method for creating a panel for providing insulated and fire retardant walls, floors and roofs, includes the steps of joining frame members together to form a panel frame of the desired dimensions, attaching face members to either side of the panel frame so that at least one enclosed space is formed within the face members and frame members, creating at least one port leading into the at least one enclosed space, and injecting urethane foam through the at least one port into the at least one enclosed space. The frame members may be positioned and the face members cut to provide window and door openings through the panel.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
129 words
A panel for providing walls, roofs, and floors having thermal insulation and fire retardance, comprising: at least two essentially parallel face members separated to form a cavity between said face members; urethane disposed within said cavity to provide thermal insulation and fire retardance; fixed frame members disposed at the periphery of said face members to provide support for the panel and to enclose said cavity; port means provided in at least one of said fixed frame members to permit the introduction of urethane into said cavity; at least one adjustable frame member selectively disposed across said cavity to divide said cavity into discrete sub-cavities; and additional port means provided in at least one of said fixed frame members to permit the introduction of urethane into each of said sub-cavities.
Claim 2
Dependent Claim
129 words
A panel for providing walls, roofs, and floors having thermal insulation and fire retardance, comprising: at least two essentially parallel face members separated to form a cavity between said face members; urethane disposed within said cavity to provide thermal insulation and fire retardance; fixed frame members disposed at the periphery of said face members to provide support for the panel and to enclose said cavity; port means provided in at least one of said fixed frame members to permit the introduction of urethane into said cavity; at least one adjustable frame member selectively disposed across said cavity to divide said cavity into discrete sub-cavities; and additional port means provided in at least one of said fixed frame members to permit the introduction of urethane into each of said sub-cavities.
Claim 3
Dependent Claim
17 words
A panel as in claim 1, wherein at least one face member is made of stucco board.
Claim 4
Dependent Claim
16 words
A panel as in claim 1, wherein at least one face member is made of drywall.
Claim 5
Dependent Claim
17 words
A panel as in claim 1, wherein at least one face member is made of plywood decking.
Claim 6
Dependent Claim
22 words
A panel as in claim 1 for forming a roof, additionally comprising a drip edge for deflecting flowing water off the panel.
Claim 7
Independent Claim
106 words
A method for creating a panel for providing insulating and fire retardant walls, floors and roofs, comprising the steps of: joining frame members together to form a panel frame of the desired panel dimensions, attaching face members to either side pf the panel frame so that at least one enclosed space is formedd within the face members and frame members, creating at least one part leading into the at least one enclosed space, injecting urethane foam through the at least one port into the at least one enclosed space, providing the panel with an adjustable frame member dividing said enclosed space into at least two sub-spaces.
Claim 8
Independent Claim
106 words
A method for creating a panel for providing insulating and fire retardant walls, floors and roofs, comprising the steps of: joining frame members together to form a panel frame of the desired panel dimensions, attaching face members to either side pf the panel frame so that at least one enclosed space is formedd within the face members and frame members, creating at least one part leading into the at least one enclosed space, injecting urethane foam through the at least one port into the at least one enclosed space, providing the panel with an adjustable frame member dividing said enclosed space into at least two sub-spaces.
