- Store panels in an ultra-low freezer* so PCM is solid (i.e. 48 hrs. @ -30°C).
- Before assembly, shake panels to verify PCM is solid. If liquid is heard, restart at step 2a to ensure longest hold time. Using liquid panels, or panels with a solid/liquid combination, decreases hold time
Store in the coldest area of the freezer; space out panels for good air flow; if stacking, insert a spacer (pencil, tongue depressor, etc.) in between each.
