Effect of Temperature on Long-Term Thermal Conductivity of Closed-Cell Insulation Materials

Round 1

Reviewer 1 Report

Dear Authors,

The study is very important while considering the fluctuations in the temperature over the year. It's well planned and executed. The following are some specific doubts:

1. Why is an increment of 30 degrees chosen, why not smaller intervals.
2. Will there be changes in behavior if smaller intervals are taken?
3. The explanation of extruded polystyrene behavior could be discussed a little more.

The paper could be accepted for publication in the journal Building Materials, and Repair and renovation in the current form.

Reviewer 2 Report

The authors presented an interesting study on the temperature-dependent variation of thermal conductivity in PIR and XPS materials. There are, however, a few minor things that must be addressed before the final approval of the manuscript:

1. It's interesting to learn about different standards in the introduction section, however, it would be even more interesting to see some comparison of studies in the literature.
2. On the first page, please indicate the type of paper.
3. On line 63, I believe there is an error in the unit representation; please correct it.
4. Some figures are not close to the mentioned point; please move the figures and tables closer to the mentioned point.
5. The results section, in my opinion, lacks proper reasoning for the variation in thermal conductivity for different conditions.
