Spray insulation shield apparatus and application method

A method for applying insulation dispensed as a curable liquid having a blowing agent or an insulation material with a curable adhesive to a plurality of spaces between a plurality of structural framing members in a wall or ceiling with an insulation confining shield, the shield comprising a sheet of elongated material having a center web section and a pair of opposed flanges extending substantially perpendicular from said center web section defining an insulation confining volume, said web section and said flanges being constructed and arranged to fit between the structural framing members in the wall or ceiling to form a confining volume and retain said insulation when applied against said web section and said flanges, comprising the steps of:

• (a) placing said shield between two adjacent structural framing members in the wall or ceiling;
• (b) attaching said flanges of said shield to said two adjacent structural framing members, respectively, with a means for fastening said flanges to said structural framing members to form said confining volume;
• and
• (c) spraying said insulation against said confining volume under a suitable pressure and in a quantity sufficient to fill said confining volume to a desired amount and an area of said structural framing members outside of said confining volume.

A method for applying insulation dispensed as a curable liquid having a blowing agent or an insulation material with a curable adhesive to a plurality of spaces between a plurality of structural framing members in a wall or ceiling with an insulation confining shield, the shield comprising a sheet of elongated material having a center web section and a pair of opposed flanges extending substantially perpendicular from said center web section defining a blowable insulation confining volume, said web section and said flanges being constructed and arranged to fit between the structural framing members in the wall or ceiling to retain said insulation when applied against said web section and said flanges, said flanges having a plurality of vent apertures defined therethrough, wherein said vent apertures are a minimum of about 7/16 inch wide, comprising the steps of:

• (a) placing said shield between two adjacent structural framing members in the wall or ceiling such that said vent apertures in said flanges are unobstructed by said structural framing members to communicate said confining volume with an area outside of said confining volume;
• (b) attaching said flanges of said shield to said two adjacent structural framing members, respectively, with a means for fastening said flanges to said structural framing members;
• and
• (c) spraying said insulation against said confining volume under a suitable pressure and in a quantity sufficient to fill said confining volume to a desired amount and to cause a quantity of said insulation to pass through said vent apertures in said flanges and adhere to an area of said structural framing members outside of said confining volume.

A method for applying insulation dispensed as a curable liquid having a blowing agent or an insulation material with a curable adhesive to a plurality of spaces between a plurality of structural framing members adjacent to an eave of a building with an insulation confining shield, the shield comprising a sheet of elongated material having a center web section and a pair of opposed flanges, an upper and lower flange, extending from said center web section defining an insulation confining volume, said web section and said flanges being constructed and arranged to fit between the structural framing members to retain said insulation when applied against said web section, said upper flange forming a vent, comprising the steps of:

• (a) placing said shield between two adjacent structural framing members and adjacent to the eave;
• (b) attaching said flanges of said shield to a roof portion and a ceiling portion, respectively, with a means for fastening said flanges to said roof and said ceiling;
• and
• (c) spraying said insulation against said confining volume under a suitable pressure and in a quantity sufficient to fill said confining volume to a desired amount.

A method for applying insulation dispensed as a curable liquid having a blowing agent to a confined area defined by a space between floor joists, flooring, a top plate, and an insulation confining shield, the shield comprising a sheet of elongated material having a central web section, a pair of side flanges, and a pair of top and bottom flanges extending substantially perpendicular from said center web section, said web section and said side, top and bottom flanges constructed to fit between the floor joists, the flooring, and the top plate of a building, the central web section having a centrally located aperture for injecting said insulation and perforations where said central web section meet said pair of side flanges and said top and bottom flanges, comprising the steps of:

• (a) placing the shield between two adjacent floor joists, adjacent to rim board;
• (b) attaching said bottom flange, of said shield to the top plate of the building with a means for fastening said shield to said top plate;
• (c) attaching the side flanges to said floor joists with a means for fastening said shield to said floor joists;
• (d) attaching the top flange of said shield to the flooring with a means for fastening said shield to said flooring;
• and
• (e) spraying said insulation through said centrally located aperture, filling said confined area to a desired amount, said insulation migrating through said perforations.
