The correct envelope decision depends on one core question: cold storage shell or temperature-controlled operation.
01
profiled sheet
best for cold use
lowest capex option
02
sandwich panel
for insulated use
standard warehouse choice
03
PIR core
max efficiency
high-performance thermal option
04
fire class
critical filter
must match facility category
Material options
- Profiled sheet: minimal upfront cost, no intrinsic insulation.
- EPS sandwich panel: balanced budget/performance for typical heated facilities.
- Mineral wool sandwich panel: selected where non-combustible core is required.
- PIR panel: premium thermal efficiency and reduced panel thickness.
Practical selection logic
| Scenario | Recommended envelope |
|---|---|
| Unheated storage | Profiled sheet |
| Standard heated warehouse | Sandwich panel (EPS/PIR depending on target) |
| Fire-sensitive storage category | Mineral wool core panel |
| Energy-critical operation | PIR panel |
Common mistake
Trying to retrofit insulation behind profiled sheet without proper envelope engineering often leads to thermal bridges, condensation, and higher lifecycle costs.

Ключевой вывод
Profiled sheet is a capex-first solution for cold storage. For heated and operationally controlled warehouses, sandwich systems are typically the correct engineering baseline.
