- the flap of each panel can be at least partially directly attached to a flap of an adjacent panel. It is also conceived that the end tab 212 can be located on the outside of the carton when assembled.
- system of inserts for insulating a carton includes a top insert
- a bottom insert 304 a frontal insert 306, a rear insert 308, a first side insert, and a second side insert 312.

- each inset includes a frontal layer including a reflective barrier
- the top side of the insert shown in Fig 5-5c includes two tabs 320 aligned asymmetrically with respect to a length L9 of the top side.
- the insert shown in Fig. 5-5c corresponds to the top 302 and bottom 304 inserts of Fig. 3.
- the insert shown in Fig. 6-6a includes two notches 322 symmetrically disposed along a length L12.

- the reflective barrier 314 of each first insert faces the interior space 401, and the reflective barrier 314 of each second insert 303 faces away from the interior space 401. This arrangement ensures that energyloss and gain are limited to the interior space 401. When assembled, the inserts minimize airflow into and out of the interior space. It is also conceived that the reflective barrier 314 faces the exterior, to provide further energy efficiency.
- the interior space can be airtight when folded the inserts are assemble properly.
