Yes, but to get the panels truly hard, the freezer must maintain a temperature lower than -30°C. Otherwise, the panel will be at the temperature of the freezer (in a liquid state) and just won’t last as long.

Your freezer must be below at least -15°C. -25°C or below is recommended to get the panels solid (for maximum hold time). The colder the storage environment, the less time is needed to condition the panels for use.
