Abstract
A self-sealing insulated panel, comprising an insulating foam board adhered or attached to a manufactured wood structural panel (e.g., oriented-strand board (OSB), plywood, or the like). The corresponding opposing edges of the insulating foam board comprise the two corresponding elements (male and female) of a modified ship-lap joint. The self-sealing insulated panel provides a component of an air-resistant and weather/water-resistant barrier in addition to insulation for a wall structure when installed when the foam board is placed facing outward towards the exterior face of the wall. The foam board provides insulation value as a foam insulation layer if placed facing inwards towards the interior of the wall.
Claims13
A modified shiplap joint, comprising:
- an underlap element with a back face, a front face, a frontward-facing main face parallel to the underlap back face and underlap front face, an inner edge face extending from the underlap main face to the underlap back face, and an outer edge face extending at an obtuse angle from the main face to the front face;
- and
- an overlap element with a back face, a front face, a backward-facing main face parallel to the overlap back face and overlap front face, an inner edge face extending from the overlap main face to the overlap back face, and a three-part outer edge comprising a first portion orthogonal to the overlap main face and adjacent thereto, a second portion orthogonal to the front face of the overlap element and adjacent thereto, and a third portion extending between the first portion and the second portion, and parallel to the overlap main face.
