Abstract

Embodiments of the invention provide methods and systems for insulating a cavity of a structure. A system may include an insulation machine having an insulation blower that blows insulation into the cavity and a hose having a lumen throughwhich the loose fill insulation is blown. The system may also include a cover positionable atop the cavity of the structure. The cover may include an aperture throughwhich the distal end of the hose is inserted to blow the loose fill insulation into the cavity and an electrically conductive material or layer. The electrically conductive material or layer may electrically contact the hose when the hose is inserted through the aperture. The system may further include a ground wire electrically coupled with the cover to dissipate a charge from the hose by providing an electric path for the charge.

Claims (61)

1. A method for insulating a cavity comprising:

providing a blowing machine configured to blow loose fill insulation material into a cavity of a structure;

providing a hose having a proximal end, a distal end, and a lumen throughwhich the loose fill insulation material is blown;

connecting the proximal end of the hose to the blowing machine;

positioning a cover atop the cavity of the structure, the cover being electrically conductive and having at least one aperture;

connecting a ground wire to the cover;

inserting the distal end of the hose through the aperture of the cover;

operating the blowing machine to blow the loose fill insulation material into the cavity; and

dissipating a charge from the hose via the electrically conductive cover and ground wire, the charge being generated as the loose fill insulation material is blown through the hose.

2. The method of claim 1 , wherein the distal end of the hose comprises an electrically conductive material, and wherein the method further comprises connecting a second ground wire to the distal end of the hose.

3. The method of claim 2 , wherein the electrically conductive material comprises a metallic tubing positioned over the distal end of the hose.

4. The method of claim 2 , wherein the hose comprises metallic tubing.

5. The method of claim 1 , further comprising positioning an electrically conductive material on one side of the cover so that the cover comprises an electrically conductive layer.

6. The method of claim 1 , wherein the cover comprises a plurality of apertures spaced across an opening of the cavity when the cover is positioned atop the cavity, and wherein the method further comprises:

blowing a first amount of loose fill insulation material into the cavity through the aperture;

withdrawing the distal end of the hose from the aperture;

inserting the distal end of the hose through an additional aperture; and

blowing a second amount of loose fill insulation material into the cavity through the additional aperture.

7. The method of claim 1 , wherein positioning the cover atop the cavity of the structure comprises positioning the cover atop a cavity of a spa or a wall of a manufactured home.

8. The method of claim 1 , further comprising connecting an opposite end of the ground wire to an electrically conductive column of a building or a ground spike.

9. The method of claim 1 , further comprising dissipating a second charge from the cavity of the structure via the electrically conductive cover and ground wire, the second charge being generated as the loose fill insulation material is blown into the cavity.

10. An apparatus for dissipating a charge during application of loose fill insulation to a cavity of a structure, the apparatus comprising:

a cover positionable atop a cavity of a structure to be filled with the loose fill insulation, the cover having a plurality of apertures throughwhich a distal end of an insulation hose is positioned to blow the loose fill insulation into the cavity of the structure; and

an electrically conductive material positioned on one side of the cover, the electrically conductive material contacting the insulation hose when the insulation hose is positioned through the aperture,

wherein the electrically conductive material is electrically coupled with a ground wire so as to dissipate a charge from the insulation hose by providing an electric path for the charge, the charge being generated as the loose fill insulation is blown through the insulation hose.

11. The apparatus of claim 10 , wherein the cover is configured to fit atop a cavity of a spa.

12. The apparatus of claim 10 , wherein the cover is configured to fit atop a cavity of a manufactured home wall.

13. The apparatus of claim 10 , wherein the structure comprises one or more structures selected from the group consisting of:

a spa;

a component of a manufactured home;

an appliance;

a rail car;

a wall of a transportation vehicle;

a storage tank; and

a pipe.

14. The apparatus of claim 12 , wherein one or more of the plurality of apertures are spaced on opposite sides of a stud of the manufactured home wall.

15. A system for dissipating a charge during application of loose fill insulation to a cavity of a structure, the system comprising:

an insulation application machine comprising:

an insulation blower configured to blow the loose fill insulation into the cavity of the structure; and

a hose having a proximal end, a distal end, and a lumen throughwhich the loose fill insulation is blown, the proximal end of the hose being coupled with the insulation blower;

a cover positionable atop the cavity of the structure, the cover comprising:

one or more apertures throughwhich the distal end of the hose is positioned to blow the loose fill insulation into the cavity, and

an electrically conductive material, wherein the electrically conductive material contacts the hose when the hose is positioned through the aperture; and

a ground wire electrically coupled with the cover so as to dissipate a charge from the hose by providing an electric path for the charge, the charge being generated as the loose fill insulation is blown through the hose.

16. The system of claim 15 , wherein the hose comprises an electrically conductive material, and wherein a second ground wire is electrically coupled with the hose so as to dissipate the charge from the hose by providing a second electric path for the charge.

17. The system of claim 16 , wherein the hose comprises a metallic tubing positioned over the distal end of the hose, and wherein the second ground wire is electrically coupled with the metallic tubing.

18. The system of claim 15 , wherein the cover comprises an electrically conductive layer of material positioned on one side of the cover.

19. The system of claim 18 , wherein the cover comprises a second electrically conductive layer of material positioned on an opposite side of the cover.

20. The system of claim 15 , further comprising a grounding member electrically coupled with the ground wire.

21. The system of claim 20 , wherein the grounding member comprising an electrically conductive column of a building or a ground spike.

22. The system of claim 15 , wherein the cover is configured to dissipate a second charge from the cavity of the structure, the second charge being generated as the loose fill insulation material is blown within the cavity.

23. A method for insulating a cavity comprising:

providing a blowing machine configured to blow loose fill insulation into a cavity of a structure;

providing a hose having a proximal end, a distal end, and a lumen throughwhich the loose fill insulation is blown, the hose having an electrically conductive distal end;

connecting the proximal end of the hose to the blowing machine;

connecting a ground wire to the electrically conductive distal end;

operating the blowing machine to blow the loose fill insulation into the cavity;
