Roof insulation systems

Abstract

An insulation system includes insulation support wires connected to wooden structural members that support roof sheathing. Insulation batts are disposed between the wooden structural members and on the insulation support wire. Portions of the insulation batts are disposed directly under bottommost surfaces of the wooden structural members.

         23 . The insulation system of  claim 21  wherein the insulation bats engage the sheathing panels. 
     
     
         24 . The insulation system of  claim 21  wherein the insulation support wires are connected directly to the wooden structural members. 
     
     
         25 . The insulation system of  claim 21  wherein the insulation support wires are connected to the wooden structural members by standoffs. 
     
     
         26 . The insulation system of  claim 21  wherein the insulation support wires run parallel to the wooden structural members. 
     
     
         27 . The insulation system of  claim 21  wherein the insulation support wires run perpendicular to the wooden structural members. 
     
     
         28 . The insulation system of  claim 21  wherein the insulation support wires run at different angles relative to the wooden structural members to form a wire insulation support web. 
     
     
         29 . An insulation system comprising:
 wooden structural members that are spaced apart;   sheathing panels disposed on top of the wooden structural members;   insulation batts disposed between the wooden structural members;   pins extending through the insulation batts that secure the insulation batts to the sheathing panel.   
     
     
         30 . The insulation system of  claim 29  wherein portions of the insulation batts are disposed directly under bottommost surfaces of the wooden structural members. 
     
     
         31 . The insulation system of  claim 29  wherein the pins are made from a flexible material. 
     
     
         32 . The insulation system of  claim 29  wherein the insulation batts are compressed to fit between the wooden structural members. 
     
     
         33 . The insulation system of  claim 29  wherein the insulation batts engage the sheathing panels. 
     
     
         34 . An insulation system comprising:
 spaced apart wooden trusses, wherein each spaced apart wooden truss comprises a pair of truss chords that are connected together at an angle by a plurality of wooden truss webs;   sheathing panels disposed on top of the spaced apart wooden trusses;   a plurality of support members attached to the truss webs below the truss chords;   insulation supported by the support members.   
     
     
         35 . The insulation system of  claim 34  further comprising insulation support material attached to the support members and loosefill insulation disposed on the insulation support material directly below the truss chords. 
     
     
         36 . The insulation system of  claim 34  further wherein the insulation comprises insulation batts disposed on the support members and portions of the insulation batts are disposed directly below the truss chords. 
     
     
         37 . The insulation system of  claim 34  wherein the insulation batts engage the sheathing panels. 
     
     
         38 . The insulation system of  claim 34  wherein the plurality of support members are parallel to the truss chords. 
     
     
         39 . The insulation system of  claim 34  wherein the plurality of support members are attached to sides of the truss webs. 
     
     
         40 . The insulation system of  claim 34  wherein the plurality of support members are attached to ends of the truss webs.
