Insulated trim for windows and doors

Abstract

A trim product with integrated rigid foam insulation attached thereto. The foam insulation portion is trimmed flush to the back of the trim product. When installed, the insulation on the trim product forms a substantially continuous insulation envelope with similar foam insulation installed on the adjacent insulated panels of the construction. The trim product may be used to form the header, sill, or jambs for a window or a door or similar structure.

What is claimed is: 
     
         1 . A system for trimming windows, doors and other openings in a wall of a building structure, comprising:
 a plurality of integrated trim pieces with a length, a width, a thickness, a front face, a back face, a first edge, and a second edge, each of said plurality of trim pieces comprising a first section and a second section, the first section comprising a wood-based substrate and the second section comprising a foam insulation attached to and integrated with the first section;   wherein the first section forms a L-shape in cross-section, and the second section forms a rectilinear-shape in cross-section to fit with the L-shape of the first section, so that when integrated, the first section and second section are rectilinear in cross-section;   wherein the second section extends the length of the respective trim piece, and across part of the back face and across part of the first edge thereof;   wherein a particular trim piece is configured to be placed with the second edge adjacent to a window or door or other opening in a wall of a building structure.   
     
     
         2 . The system of  claim 1 , wherein said particular trim piece is configured to be placed with the first edge facing away from the window or door or other opening, and adjacent or proximate to one or more insulated siding panels. 
     
     
         3 . The system of  claim 2 , wherein said particular trim piece is a header trim piece. 
     
     
         4 . The system of  claim 2 , wherein the particular trim piece is a sill trim piece. 
     
     
         5 . The system of  claim 2 , wherein the particular trim piece is a jamb trim piece. 
     
     
         6 . The system of  claim 1 , wherein the wood-based substrate is oriented strand board. 
     
     
         7 . The system of  claim 1 , wherein the wood-based substrate is engineered or manufactured wood. 
     
     
         8 . The system of  claim 1 , wherein the foam insulation is rigid foam insulation. 
     
     
         9 . The system of  claim 2 , wherein the insulated siding panel comprises a wood-based substrate and a foam insulation layer adhered thereo. 
     
     
         10 . The system of  claim 9 , wherein the foam insulation layer of the insulated siding panel and the foam insulation of the trim piece are the same type of foam insulation. 
     
     
         11 . The system of  claim 10 , wherein the foam insulation layer of the insulated siding panel and the foam insulation of the trim piece are the same type thickness. 
     
     
         12 . The system of  claim 1 , wherein the wall of a building structure comprises a plurality of wood-based structural panels, a weather/water resistant barrier overlaying the plurality of wood-based structure panels, and a plurality of insulated siding panels overlaying the weather/water resistant barrier;
 wherein the window or door or other opening extends through these layers of the wall.   
     
     
         13 . The system of  claim 12 , wherein the window or door or other opening has a top side, a bottom side, a right side, and a left side; and four particular trim pieces are affixed adjacent to a corresponding side, each with the back side facing the wood-based structural panels, and the first edge facing away facing away from the window or door or other opening. 
     
     
         14 . The system of  claim 13 , wherein the four particular trim pieces comprise:
 a header trim piece affixed along the top side;   a sill trim piece affixed along the bottom side;   a right side trim piece affixed along the right side; and   a left side trim piece affixed along the left side.   
     
     
         15 . The system of  claim 14 , wherein each end of the sill trim piece forms a 45-degree angled joint with the adjacent end of the corresponding right side trim piece and the corresponding left side trim piece. 
     
     
         16 . The system of  claim 14 , wherein each end of the header trim piece forms a flat or butt joint with the adjacent end of the corresponding right side trim piece and the corresponding left side trim piece.
