Insulation system and method for buildings

Abstract

An apparatus, method and system of insulating a building such as a poultry barn uses netting structurally of the type to hold sod together. The netting is stapled to the bottom of trusses making up the ceiling of a barn and the attic of the barn. Ceiling material is superimposed below the netting to form a ceiling. Loose insulation, typically fiberglass, is blown onto the netting to be held thereby and to form an insulation layer in the attic of the barn.

Claims

1. An apparatus for providing insulation in an attic of a building having a plurality of trusses with bottom surfaces making up a bottom surface of the attic of the building, comprising: mesh netting attached to the bottom surfaces of the plurality of trusses making up the bottom surface of an the attic of the building; ceiling material installed below the mesh netting, the ceiling material comprising a woven ceiling material, and further comprising the woven ceiling material stapled to the plurality of trusses to which the mesh netting is attached; and loose blown insulation distributed uniformly over the mesh netting within the attic of the building to a depth required for an insulation value desired, said mesh netting having openings sufficiently small to prevent the loose blown insulation from passing through the mesh netting and capturing the loose insulation to prevent the loose insulation from migrating.

2. The apparatus of claim 1, wherein said loose blown insulation comprises fiberglass wool.

3. The apparatus of claim 1, wherein said mesh netting has a strand count which comprises: 13.2+/2 per 10 MD, 7.0+/0.5 per 10 TD.

4. The apparatus of claim 1, wherein said building comprises a poultry barn.

5. The apparatus of claim 1, wherein said mesh netting is stapled to the plurality of trusses in a manner that said loose blown insulation is retained thereon while allowing the installed ceiling material to function as a ceiling.

6. The apparatus of claim 1, wherein said mesh netting is non-biodegradable.

7. The apparatus of claim 6, wherein about 10 percent of mesh netting overage is provided to achieve controlled sagging of the mesh netting when stapled to the plurality of trusses.

8. The apparatus of claim 7, wherein when said ceiling material is installed, the mesh netting is exposed to the attic of the building.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Having thus briefly described the invention, the same will become better understood from the following detailed description made with reference to the drawings wherein:

(2) FIG. 1 is a cross-sectional view of a standard poultry barn or house truss with a pitched roof line;

(3) FIG. 2 is an enlarged view of a portion of a poultry barn truss showing the arrangement of blown insulation, netting and ceiling material in assembled form; and

(4) FIG. 3 is an exploded view of the structure of FIG. 1 showing the arrangement of insulation, netting and ceiling material in relationship to trusses of the attic.

DETAILED DESCRIPTION OF EMBODIMENTS

(5) In accordance with the invention an improved apparatus, method and system of providing insulation in a building attic, such as a poultry barn attic is provided.

(6) The system of the invention involves the use of netting of the type which is similar to that which is used, for example, as a sod matrix to hold sod together. The type of netting used in sod is however biodegradable which is not desirable. By using conventional manufacturing techniques, a similarly structured netting can be manufactured to be non-biodegradable so it maintains its structure when used in the system of the invention, and is preferred for such use.

(7) In accordance with the invention the size of the mesh in the netting has some significance, but is not critical and can be of a variety of different sizes so long as it is sufficient to hold the insulation, which is blown onto the netting in place over time.

(8) Thus, as shown in FIG. 1, a truss structure 11 of a building such as a standard poultry barn is constructed and is pitched in a manner well known to those of ordinary skill in the art. As the poultry barn is constructed, mesh netting 13 is stapled to the bottom of the trusses 18 making up the lower part of the attic truss structure 11 facing the building's interior space. Thereafter, ceiling material such as triple ply woven ceiling material 15 is typically stapled below the netting 13 as shown in FIG. 2, to form the ceiling for the structure.

(9) As further illustrated in the enlarged portion 17 shown in greater detail in FIG. 2, once the netting 13 and the ceiling material 15 are assembled together to form the lower portion of the attic and the ceiling of the structure, fiberglass insulation 19 is blown from the top onto the netting 13 within the attic and is retained thereon in a stable manner with little or no migration of insulation.

(10) FIG. 3 shows the system of the invention in which the fiberglass insulation 19, the mesh netting 13, and the ceiling paper 15 are shown in exploded form. The mesh netting 13 is first attached to truss 18 by being moved in the direction of arrow A. The ceiling paper 15 is then attached to the truss 18 by being moved in the direction of arrow B. The insulation 19 is then blown from above in the direction of arrow C onto the mesh netting 13 between the trusses 18.

(11) By way of further explanation, the netting used in the invention, which is typically similar in structure to that used to hold sod together, but in this case preferably being non-biodegradable to ensure longevity, is fastened securely but loosely to the underside of trusses or rafters with approximately ten percent (10%) overage of netting to achieve mild sagging or bagging. Thus, for example, for every one thousand (1,000) square feet covered one would need one thousand one hundred (1,100) square feet of netting. Standard ceiling material required for the project is then installed under the netting so that the netting is exposed toward the attic area. A required thickness of standard fiberglass blowing wool is then blown over the netting to be deposited therein in a manner in which it does not migrate.

(12) The netting should be of a size in which enough netting is provided to adequately go from front to back of a house or building in one piece with overlapping two (2) to three (3) inches from side to side of width of the house or building until the entire ceiling or what is to be the ceiling for the attic is covered. To install the netting, the installer starts at the peak and works their way towards the side walls and if there is a lap at the peak, a twelve (12) inch or thereabouts overlap is provided. Typically, for every four (4) feet from peak or center down the remainder of the structure, the netting should be lapped back onto itself to create migration cavities. The netting should be fastened about every twenty four (24) inches to the bottom of trusses. Thus, fastening to every other truss should be sufficient in most structures. The ceiling material is then installed under the netting in a normal and conventional manner, and the fastening of the ceiling material will also further secure the netting in place. When the blowing wool is installed, it should be installed carefully, since it is not going to slide as it normally does without the presence of the netting.
