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.

Abstract: Described herein are non-halogenated flame resistant adhesive compositions, halogen-free vapor retarders, facings for insulation products, and more specifically to flexible, low permeance facings utilizing non halogenated flame retardant systems for insulation products, and processes for making such products. The non-halogenated flame resistant adhesives can comprise non-halogenated latexes and/or non-halogenated flame retardants. The insulation products described herein may include a base insulation layer composed of or including a composite or construction board, blanket, batt, pipes, or roll. An insulation product as provided includes a base insulation layer (e.g., a construction or composite board) and at least one halogen-free facer bonded with a non-halogenated flame resistant adhesive composition to one or more sides or surfaces of the base insulation layer.
