Abstract
An integrated joint sealing system that is incorporated into the edges of a sheathing panel, which also may have a factory bonded weather resistive barrier. The edges of each panel are configured as a shiplap joint, or similarly functioning joint, that is present as either an overlap or underlap on each of the four panel edges. The arrangement of the joints are such that one edge will have an overlap and the opposite edge will have an underlap. A flexible gasket material (or materials) is factory applied to one or both sides (underlap and/or overlap) of the shiplap joint. This flexible gasket material, when overlapped with adjacent shiplap panels, provides a weather resistive seal to limit both water and air penetration.
Claims13
A method of making a self-sealing panel product, comprising:
- providing a sheathing panel comprising a wood-based material with a front face, a back face, first and second opposing edges, and third and fourth opposing edge;
- machining a first joint section in the first edge and the third edge;
- machining a second joint section in the second edge and the fourth edge, wherein the second joint section and the first joint section are configured to mate and form a joint;
- bonding, in a factory, a first self-sealing material to and completely, evenly and contiguously covering one or more faces of the first joint sections;
- bonding, in a factory, a second self-sealing material to and completely, evenly and contiguously covering one or more faces of the second joint sections;
- and
- bonding, in a factory, a portion of the front face adjacent to the first edge and the third edge with a third self-sealing material;
- wherein the first self-sealing material and the second self-sealing material form a water-resistant and air-resistant bond when placed in contact.

- bonding, in a factory, a second self-sealing material to and completely, evenly and contiguously covering one or more faces of the second joint sections;
- and
- extending the first self-sealing material or the second self-sealing material over a weather resistive barrier on the front face proximate to at least one of the first, second, third and fourth edges;
- wherein the first self-sealing material comprises one or more of rubber, silicone, polyurethane foam, urethane foam, acrylic, polyvinyl acetate, and polyvinyl ester.
