Urethane insulating panel and method

DETAILED DESCRIPTION The present invention accomplishes the above-stated objectives, as well as others, as may be determined by a fair reading and interpretation of the entire specification.
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.
The frame members are preferably U-shaped channels and made of metal.
The face members may be secured to the frame members with sheet metal screws.
The face members may be made of stucco board, such as a product known as Densglass, of drywall, or of plywood decking.
The frame members may extend only along the perimeter of the face members of both along and within the perimeter of the face members.
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 at least one port is preferably created in at least one frame member.
Screws may be fitted through the frame into an object separate from the panel to secure the panel in position.
The frame members may be positioned and the face members cut to provide window and door openings through the panel.
