Abstract

A duct insulation product may include an insulation material and a moisture barrier material coupled with the insulation material. The moisture barrier material may form an outer surface of the duct insulation product. The moisture barrier material may include at least one closure flap along at least one side of the moisture barrier material. The closure flap may extend beyond a periphery of the insulation material along at least one side of the insulation material. At least a portion of an inner surface of the closure flap may include an adhesive material.

First claim

What is claimed is:

1. A duct insulation product comprising:
an insulation material;
a moisture barrier material coupled with the insulation material, the moisture barrier material forming an outer surface of the duct insulation product and covering an entire exterior surface of the insulation material, wherein the outer surface of the moisture barrier material comprises a foil facing or a poly facing, wherein:
the moisture barrier material extends continuously between a first edge and an opposed second edge, and comprises at least one closure flap along the first edge, the second edge, or both the first edge and the second edge of the moisture barrier material, the closure flap extending beyond a periphery of the insulation material along at least two adjacent edges of the insulation material; and
at least a portion of an inner surface of the closure flap comprises an adhesive material disposed along the at least two adjacent edges of the insulation material; and

a release liner applied atop the adhesive material along the at least two adjacent edges of the insulation material.

2. The duct insulation product of claim 1 , wherein:
the duct insulation product is flexible.

3. The duct insulation product of claim 1 , wherein:
the insulation material comprises fiberglass.

4. The duct insulation product of claim 1 , wherein:
the moisture barrier material comprises a foil scrim kraft paper laminate, fiberglass reinforced faces, a poly facing, polyisocyanurate, an all service jacketing facing.

5. The duct insulation product of claim 1 , wherein:
the adhesive material is characterized by a thickness of greater than or about 0.01 mm.

6. The duct insulation product of claim 1 , wherein:
the adhesive material is characterized by a peel strength of greater than or about 60 ounces per inch.

7. The duct insulation product of claim 1 , wherein:
the adhesive material is disposed along substantially an entire length of the moisture barrier material.

8. The duct insulation product of claim 1 , wherein:
the adhesive material comprises double-sided tape.

9. The duct insulation product of claim 1 , wherein:
the duct insulation product is rolled up prior to installation; and
the adhesive material is applied to the closure flap prior to rolling up the insulation material.

10. A duct insulation system comprising:
a plurality of duct insulation products, each duct insulation product comprising an insulation material and a moisture barrier material coupled with the insulation material, wherein:
the moisture barrier material of each duct insulation product covers an entire exterior surface of the insulation material of the respective duct insulation product;
the moisture barrier material extends continuously between a first edge and an opposed second edge, and beyond a periphery of the insulation material along the first edge, the second edge, or both the first edge and the second edge of the insulation material to form a closure flap that extends beyond a periphery of the insulation material along at least two adjacent edges of the insulation material;
at least a portion of an inner surface of the closure flap along both of the at least two adjacent edges of the insulation material comprises an adhesive material; and
the adhesive material of the closure flap of a first duct insulation product couples with and secures a second duct insulation product.

11. The duct insulation system of claim 10 , wherein: the duct insulation system is positioned around one or more ducts.

12. The duct insulation system of claim 10 , wherein:
the adhesive material is characterized by a thickness of greater than or about 0.01 mm; and
the adhesive material is characterized by a width of less than or about 8.0 inches.

13. The duct insulation system of claim 10 , wherein:
the moisture barrier material comprises a length at least double a width of the moisture barrier material.

14. The duct insulation system of claim 10 , wherein:
the adhesive material is disposed along substantially an entire length of the moisture barrier material.

15. The duct insulation system of claim 10 , wherein:
the first edge of each duct insulation product is defined by a male shiplap profile; and
the second edge of each duct insulation product is defined by a female shiplap profile, wherein the closure flap and the adhesive material are defined on at least one inner surface of the second edge.

16. A duct insulation manufacturing method comprising:
coupling an insulation material to a moisture barrier material to form an insulation product, the moisture barrier material forming an outer surface of the duct insulation, wherein:
the insulation material comprises a plurality of planar segments that are pivotable relative to one another;
the outer surface of the moisture barrier material comprises a foil facing or a poly facing;
the moisture barrier material extends continuously between a first edge and an opposed second edge, and beyond a periphery of the insulation material along the first edge, the second edge, or both the first edge and the second edge to form at least one closure flap;
the at least one closure flap extending beyond a periphery of the insulation material along at least two adjacent edges of the insulation material; and
the moisture barrier material covers an entire exterior surface of the insulation material;
disposing an adhesive material on the at least one closure flap along the at least two adjacent edges of the insulation material; and
applying a release liner to the adhesive material along the at least two adjacent edges of the insulation material, wherein the release liner protects the adhesive material prior to application.

17. The duct insulation manufacturing method of claim 16 , further comprising:
rolling the insulation material and the moisture barrier material for storage after applying release liner.

18. The duct insulation manufacturing method of claim 16 , wherein:
the moisture barrier material extends beyond the insulation material along two or more edges to form two or more closure flaps; and
further comprising disposing the adhesive material on two or more closure flaps.

19. The duct insulation manufacturing method of claim 16 , wherein:
the adhesive material is characterized by a thickness of between about 0.01 mm and about 200.0 mm; and
the adhesive material is characterized by a width of between about 0.5 inches and about 8.0 inches.

20. The duct insulation manufacturing method of claim 16 , wherein:
the adhesive material is disposed along substantially an entire length of the at least one closure flap.
