The system comprises an insulation support material and a metal frame. The metal frame comprises a plurality of metal members, wherein at least two opposing metal members have at least one portion thereof stamped out to protrude on one side. An exterior sheathing is attached to an opposing side of the metal frame. The stamped out protrusion engages the insulation support material. This system is particularly useful for steel frame construction and does not require the use of adhesives or additional tools. The method of the present invention involves providing a metal frame having a plurality of metal members wherein at least two opposing members have at least one portion thereof stamped out to protrude on one side and an exterior sheathing attached to an opposing side. An insulation support material is engaged and tensioned on the stamped out protruded portions of the opposing metal members forming a cavity between the insulation support material and the exterior sheathing. Insulation is blown into the cavity. This method allows for positive restraint of the insulation support material and high density insulation. Thus, a high "R" value is achieved. In addition, installation is independent of weather conditions, requires no additional tools, and is more efficient than those systems currently used. ## Claims ### Claim 1 A blown-in insulation support system for metal frame construction comprising: an insulation support material selected from the group consisting of: a nylon netting; a fabric; a reinforced material; and a thin translucent cloth material for holding insulation; and a metal frame comprising a plurality of metal members, wherein at least two opposing metal members have at least one portion thereof stamped out to protrude on one side and an exterior sheathing attached to an opposing side, and wherein each stamped out protrusion engages and tensions the insulation support material. ### Claim 2 (depends on 1) A blown-in insulation support system for metal frame construction according to claim 1, wherein the insulation support material is a nylon netting. ### Claim 3 (depends on 1) A blown-in insulation support system for metal frame construction according to claim 1, wherein the metal member is selected from the group consisting of: a primary metal member and a secondary metal member. ### Claim 4 (depends on 3) A blown-in insulation support system for metal frame construction according to claim 3, wherein the primary metal member is selected from the group consisting of: a stud and a joist; and the secondary metal member is selected from the group consisting of: a purlin; a channel; and a track. ### Claim 5 (depends on 1) A blown-in insulation support system for metal frame construction according to claim 1, wherein each metal member is formed from steel. ### Claim 6 (depends on 1) A blown-in insulation support system for metal frame construction according to claim 1, wherein each metal member has a longitudinal axis and wherein the stamped portion and the longitudinal axis form an acute angle. ### Claim 7 (depends on 6) A blown-in insulation support system for metal frame construction according to claim 6, wherein the stamped portion and the longitudinal axis form an angle of about 20 degrees. ### Claim 8 A blown-in support system for steel frame construction comprising: a nylon net; and a steel frame comprising spaced apart steel top and bottom tracks and a plurality of parallel elongate steel studs extending between the top track and the bottom track spaced at intervals along the length of each track, wherein the top track, the bottom track and the elongate studs each have a longitudinal axis and each has at least one portion thereof stamped out to protrude on one side at an angle of about 20 degrees between the protruded portion and the longitudinal axis and an exterior sheathing attached to an opposing side, and wherein each stamped out protrusion engages and tensions the nylon net. ### Claim 9 A method for installing blown-in insulation in metal frame construction, the method comprising the steps of: a) providing a metal frame having a plurality of metal members wherein at least two opposing metal members have at least one stamped portion thereof stamped out to protrude on one side and an exterior sheathing attached to an opposing side; b) engaging and tensioning an insulation support material on the stamped out protruded portions of the opposing metal members forming a cavity between the exterior sheathing and the insulation support material; and c) blowing insulation into the cavity. ### Claim 10 (depends on 9) A method for installing blown-in insulation in metal frame construction according to claim 9, wherein the metal members are selected from the group consisting of: primary metal members and secondary metal members. ### Claim 11 (depends on 10) A method for installing blown-in insulation in metal frame construction according to claim 10, wherein the primary metal members are selected from the group consisting of: a stud and a joist; and the secondary metal members are selected from the group consisting of: a purlin; a channel; and a track. ### Claim 12 (depends on 9) A method for installing blown-in insulation in metal frame construction according to claim 9, wherein the metal members are formed from steel. ### Claim 13 (depends on 12) A method for installing blown-in insulation in metal frame construction according to claim 12, wherein the metal members are selected from the group consisting of: primary metal members and secondary metal members. ### Claim 14 (depends on 13) A method for installing blown-in insulation in metal frame construction according to claim 13, wherein the primary metal members are selected from the group consisting of: a stud and a joist; and the secondary metal members are selected from the group consisting of: a purlin; a channel; and a track. ### Claim 15 (depends on 9) A method for installing blown-in insulation in metal frame construction according to claim 9, wherein the insulation support material is selected from the group consisting of: a nylon netting; a fabric; a reinforced material; and a thin translucent cloth material for holding insulation. ### Claim 16 (depends on 15) A method for installing blown-in insulation in metal frame construction according to claim 15, wherein the insulation support material is a nylon netting. ### Claim 17 (depends on 9) A method for installing blown-in insulation in metal frame construction according to claim 9, wherein the insulation support material is engaged by hooking the insulation support material on the stamped out protruded portions of the opposing metal members. ### Claim 18 A method for installing blown-in insulation in steel frame construction, the method comprising the steps of: a) providing a steel frame comprising spaced apart steel top and bottom tracks and a plurality of parallel elongate steel studs extending between the top track and the bottom track spaced at intervals along the length of each track, wherein the top track, the bottom track and the elongate studs each have a longitudinal axis and each has at least one portion thereof stamped out to protrude at an angle of about 20 degrees between the protruded portion and the longitudinal axis and an exterior sheathing attached to an opposing side; b) hooking and tensioning a nylon net onto the stamped out protruded portions of the steel frame forming a cavity between the exterior sheathing and the nylon net; and c) blowing insulation into the cavity.
