ABSTRACT:
FIELD OF THE INVENTION
This invention relates generally to structural panels for building construction and is particularly directed to a structural insulated panel with improved strength and weather resistance and which affords increased flexibility in installing the panel in a building structure.
BACKGROUND OF THE INVENTION
There is a need for a ready-to-install structural panel for building construction having a weather-resistant exterior surface, a finished interior surface, and an insulating layer between the exterior and interior surfaces which can be economically mass produced and easily installed. The structural panel should be weather-resistant not only when installed in the finished building, but also when initially installed prior to completion in the event inclement weather is encountered during construction. The structural insulated panel should also be adapted for selling in home improvement stores and be capable of being installed by an “amateur” carpenter without the need for additional installation components or special installation design considerations. Moreover, the panel should meet and hopefully surpass local fire codes and should also be insect resistant.
The present invention provides the aforementioned advantages in a structural insulated panel which is weather resistant, fire resistant, easily installed, and is of high strength.
OBJECTS AND SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a structural insulated panel having spaced studs attached to its outer surface or disposed within its insulating core which facilitate attachment of an exterior facing to the panel and increase the tensile and compressive strength of the panel.
It is another object of the present invention is to provide a structural insulated panel with a C-shaped channel disposed on one or more edges of the panel to facilitate installation of the panel in a building structure or attachment of the panel to other structural insulated panels.
A further object of the present invention is to provide a structural insulated panel for building construction having an inner metal spline which facilitates installation and attachment of the panel without conducting heat through the panel's insulating core.
Yet another object of the present invention to provide a structural insulated panel for building construction with improved weather resistance both during installation and after the panel is installed.
A still further object of the present invention is to provide a drainage plane for water between an outer facing of a structural insulated panel and the panel's inner insulating core.
This invention contemplates a generally planar structural insulated panel comprising an insulating core having inner and outer opposed surfaces; first and second weather resistant, high tensile strength plastic impregnated paper (PIP) facings respectively attached to the inner and outer opposed surfaces of the insulating core for protecting the insulating core from moisture and increasing the strength of the structural insulated panel; and a plurality of studs attached in a spaced manner to at least one of the first or second PIP facings for increasing the strength of the structural insulated panel and facilitating attachment of an outer facing to the structural insulated panel and installation of the structural insulated panel in a building structure.
This invention further contemplates a structural insulated panel for use in a building structure comprising a generally planar insulating core having first and second opposed surfaces; first and second plastic impregnated paper (PIP) facings respectively disposed on the first and second opposed surfaces of the insulating core; a first plurality of studs attached in a spaced manner to the first PIP facing and a second plurality of studs attached in a spaced manner to the second PIP facing; first and second outer facings respectively disposed on and attached to the first and second pluralities of studs; first and second spaced slots in an edge of the structural insulated panel, wherein the first and second slots are respectively disposed between the insulating core and the first and second pluralities of studs; a generally C-shaped channel inserted in the first and second slots and attached to the first and second pluralities of studs; and a coupler for securely connecting the C-shaped channel to the building structure or to another structural insulated panel.
