A double-wall container, comprising:
- an inner wall;
- an outer wall attached to the inner wall;
- a single layer of expanded insulation arranged in a plurality of bands between and in contact with both the inner wall and the outer wall to create a plurality of air channels between the inner wall and the outer wall, the expanded insulation being formed from an insulating material including expandable microspheres having an activation temperature not exceeding 190° F., the plurality of bands of expanded insulation include expanded, non-ruptured microspheres.
A double-wall container, comprising:
- an inner wall;
- an outer wall attached to the inner wall;
- a single layer of expanded insulation arranged between the inner wall and the outer wall to create air gaps between the inner wall and the outer wall, the single layer of expanded insulation engaging both the inner wall and the outer wall, the single layer of expanded insulation being formed from an insulating material including expandable microspheres having an activation temperature not exceeding 190° F. such that the single layer of expanded insulation includes expanded, non-ruptured microspheres between the inner wall and the outer wall.
