Box defining walls with insulation cavities

A method of assembling a box, the method comprising:

• obtaining a blank comprising an outer side panel comprising an outer fold line, an outer bottom panel joined to the outer side panel by a fold line, a connecting strip joined to the outer side panel by a fold line, an inner side panel connected to the connecting strip by a fold line and defining a plane and comprising an inner fold line positioned parallel to the outer fold line of the outer side panel, and an inner bottom panel joined to the inner side panel by a fold line;
• obtaining a first insulator pad;
• folding the outer bottom panel such that the outer bottom panel is perpendicular to the outer side panel;
• folding the inner bottom panel such that the inner bottom panel faces the outer bottom panel;
• positioning the first insulator pad between the outer bottom panel and the inner bottom panel;
• obtaining a second insulator pad, the second insulator pad comprising an angled cut defining an edge of the second insulator pad that is angled relative to the plane of the inner side panel;
• folding the inner side panel such that the inner side panel faces the outer side panel;
• and
• positioning the second insulator pad between the outer side panel and the inner side panel such that the edge of the second insulator pad is positioned at the inner fold line;
• wherein the second insulator pad is coupled to the inner side panel and covers the inner side panel and the angled cut of the second insulator pad is at most 45-degrees.
