Abstract

The invention comprises a product. The product comprises a first foam panel having an edge, a first primary surface and an opposite second primary surface and a second foam panel having an edge, a first primary surface and an opposite second primary surface, wherein the first and second foam panels are disposed such that their edges are adjacent each other and define a joint therebetween. The product also comprises an elongate metal strip having a body portion and a projection extending outwardly from the body portion, the metal strip being disposed such that at least a portion of the projection is disposed in the joint between the foam panels and at least a portion of the body portion covers a portion of the second primary surface of the first foam panel and a portion of the second primary surface of the second foam panel. A method of making and using the composite panel is also disclosed.

First claim

What is claimed is:

1. A wall structure comprising:
a plurality of vertical stud members horizontally spaced from each other to form a wall framing structure;
an elongate metal strip having a body member and a projection extending outwardly from the body member, the metal strip being attached to at least two adjacent vertical stud members;
a first sheathing panel having an edge;
a second sheathing panel having an edge, wherein the first and second sheathing panels are disposed such that the edges of the first and second sheathing panels are adjacent each other and define a joint therebetween, wherein the metal strip is disposed such that at least a portion of the projection is disposed in the joint between the first and second sheathing panels, and
wherein each of the first and second sheathing panels consist essentially of:
a vapor permeable insulating panel having a primary surface opposite the plurality of vertical stud members;
a layer of porous reinforcing material substantially covering and adhered to the primary surface of the vapor permeable insulating panel; and
wherein the layer of reinforcing material is adhered to the primary surface of the vapor permeable insulating panel with and at least partially embedded in a water-resistant, polymeric elastomeric material that is a vapor permeable air barrier material having a water vapor transmission rating of at least 1 perm and an air permeance of less than 0.004 cfm/sq.ft. under a pressure differential of 0.3 inches of water.

2. A method of insulating a structure comprising:
securing an elongate metal strip to adjacent wall studs, the elongate metal strip having a body member and a projection extending outwardly from the body member;
securing a sheathing panel to a portion of the elongate metal strip, wherein the sheathing panel has an edge, a first primary surface and an opposite second primary surface, wherein the sheathing panel is disposed such that the projection is adjacent the edge of the sheathing panel and at least a portion of the second primary surface covers at least a portion of the body member;
wherein the sheathing panel consist essentially of:
a vapor permeable insulating panel having a primary surface opposite the plurality of vertical stud members;
a layer of reinforcing material substantially covering and adhered to the primary surface of the vapor permeable insulating panel; and
wherein the layer of porous reinforcing material is adhered to the primary surface of the vapor permeable insulating panel with and at least partially embedded in a water-resistant, polymeric elastomeric material that is a vapor permeable air barrier material having a water vapor transmission rating of at least 1 perm and an air permeance of less than 0.004 cfm/sq.ft. under a pressure differential of 0.3 inches of water.

3. The wall structure of claim 1 , wherein the layer of reinforcing material is a porous fabric, a web, a mesh or a lath.

4. The wall structure of claim 1 , wherein the layer of reinforcing material is a nonwoven plastic sheet, a nonwoven fiberglass mat, a nonwoven fiberglass mesh or a nonwoven fiberglass grid.

5. The method of insulating a structure of claim 2 , wherein the layer of reinforcing material is a porous fabric, a web, a mesh or a lath.

6. The method of insulating a structure of claim 2 , wherein the layer of reinforcing material is a nonwoven plastic sheet, a nonwoven fiberglass mat, a nonwoven fiberglass mesh or a nonwoven fiberglass grid.

7. The wall structure of claim 1 , wherein the insulating panel is made from polystyrene foam, polyisocyanurate foam or polyurethane foam.

8. The method of insulating a structure of claim 2 , wherein the insulating panel is made from polystyrene foam, polyisocyanurate foam or polyurethane foam.
