Abstract

An insulation product may include an insulation material. The insulation material may include at least one material selected from the group consisting of nonwoven insulation, aerogel insulation, mineral insulation, and foam insulation. The insulation material may include a first end and a second end positioned opposite the first end. The first end may include a protrusion. At least a portion of the protrusion may widen in a direction opposite the second end. The second end may define a cutout that substantially matches a size and shape of the protrusion. The cutout and the protrusion may be aligned with one another along a length of the insulation material.

First claim

What is claimed is:

1. An insulation product, comprising:
a first insulation material comprising at least one material selected from the group consisting of nonwoven insulation, aerogel insulation, mineral insulation, and foam insulation;
and a second insulation material comprising at least one material selected from the group consisting of nonwoven insulation, aerogel insulation, mineral insulation, and foam insulation, wherein:
each of the first insulation material and the second insulation material comprises a first end, a second end opposite the first end, and lateral edges that extend between the first end and the second end;
the lateral edges are substantially linear;
the first end of each of the first insulation material and the second insulation material comprises a protrusion;
the second end of each of the first insulation material and the second insulation material defines a cutout that has a size and shape that substantially matches a size and shape of the protrusion; and
the protrusion of the first insulation material is insertable within the cutout of the second insulation material to couple the first insulation material and second insulation material in an end to end fashion and to align the lateral edges of the first insulation material and the second insulation material are aligned with one another.

2. The insulation product of claim 1 , wherein:
the protrusion of the first insulation material is inserted within the cutout of the second insulation material, thereby securing the first insulation material and second insulation material together in an end-to-end configuration.

3. The insulation product of claim 2 , further comprising:
a reinforcement member positioned over a seam formed between the first insulation material and the second insulation material.

4. The insulation product of claim 3 , wherein:
the reinforcement member comprises one or both of a glass mat facer and adhesive tape.

5. The insulation product of claim 1 , further comprising:
a splice insert positioned between the first insulation material and the second insulation material, the splice insert comprising interlocking features that receive the protrusions of each of the first ends or that are insertable within the cutouts of each of the second ends to secure the first insulation material and second insulation material together in an end-to-end configuration.

6. The insulation product of claim 5 , further comprising:
a reinforcement member positioned over seams formed between the first insulation material, the splice insert, and the second insulation material.

7. The insulation product of claim 5 , further comprising:
a first reinforcement member positioned over a first seam formed between the first insulation material and the splice insert; and
a second reinforcement member positioned over a second seam formed between the splice insert and the second insulation material.

8. The insulation product of claim 5 , wherein:
the splice insert extends an entire distance between the lateral ends of the first insulation material and the second insulation material.
