ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates, in general, to a wallboard or drywall system, and, in particular, to a wallboard or drywall system marked with a grid system to facilitate the installation of wallboard or drywall and utilizing two types of vapor barriers
DESCRIPTION OF THE PRIOR ART
In the prior art various types of wallboard or drywall have been proposed. For example, U.S. Pat. No. 3,798,854 to Hinojosa et al discloses prefinished wall board which has a layer of settable material on one side and a decorative pattern formed in relief in the settable material.
U.S. Pat. No. 4,397,123 to Parker discloses drywall board with widthwise extending tear-off strips on the back side of each butt end which allows the butt ends to bend when the strips are removed.
U.S. Pat. No. 4,944,124 to Armstrong discloses a panel used for skirting on a mobile home which has a raised masonry surface.
U.S. Pat. No. 5,729,934 to Ochoa discloses an L-shaped coping for drywall corners marked with indicia to facilitate the installation.
SUMMARY OF THE INVENTION
The present invention is directed to a wallboard or drywall system with two types of measuring indicia on on side of the wallboard or drywall, and an integral, transparent vapor barrier is applied to the back side of the wallboard or drywall. In addition, the system contains adhesive coated plastic tape which can be used to seal adjacent, mating edges of wallboard or drywall panels.
It is an object of the present invention to provide a new and improvedwallboard or drywall system.
It is an object of the present invention to provide a new and improved wallboard or drywall system which has a grid system to facilitate cutting of wallboard or drywall.
It is an object of the present invention to providea new and improved wallboard or drywall system which utilizes two types of vapor barriers to protect the drywall from the damaging effects of moisture.
These and other objects and advantages of the present invention will be fully apparent from the following description, when taken in connection with the annexed drawings.
