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 self-sealing insulated panel, comprising:
- a manufactured-wood structural panel;
- a foam insulation board with a back face and a front face, the inner face affixed to a face of the manufactured-wood structural panel;
- wherein opposing edges of the foam insulation board comprise corresponding joint elements of a modified ship-lap joint, said joint elements comprising an underlap element with an outward-facing main face and an angled face extending therefrom to the outer face of the foam insulation board, and an overlap element with an inward-facing main face and a drip edge along the outermost edge, wherein the drip edge is not in contact with any part of the underlap element when the joint is formed, and the angled face is not in contact with any part of the overlap element when the joint is formed.
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.
