Closed Cell for Cold Storage

Cold storage is unforgiving — get the envelope wrong and the whole room fails.

We start with the physics: dew point, vapor drive, and why any gap in a cold envelope turns into frost, ice, and a burned-out compressor.

Then depth strategy: how to calculate closed-cell thickness for the temperature split, so the dew point stays inside the foam, not on the wall.

We cover the details that kill cold rooms: thermal bridges, joints, penetrations, and the seal around doors and refrigeration lines.

We finish with reefer trucks and trailers: spraying moving boxes, vibration, condensation in transit, and the envelope that holds the cold on the road.

This is the course for crews bidding freezers, coolers, and refrigerated transport.
