Product Q&A

Q:What is the difference between temperature control and temperature protection?

Thermal covers provide temperature protection rather than control. Unlike temperature controlled packaging that uses phase change materials to hold temperature for a validated duration, thermal covers simply slow down temperature exchange.

Q:Do thermal covers work effectively in cold weather?

Yes, they often perform better in cold weather than in hot conditions. Testing shows it takes longer for freight temperature to drop in cold weather than it does to rise.

Q:How easy is it to fit and remove thermal covers?

Preformed covers fit like a hat and seal with tape in a few minutes. Removal is equally quick, though silver-backed bubble rolls may take up to 20 minutes for two people.

Q:Does adding a second cover double the performance?

No, but it improves performance considerably by an estimated 40-60% depending on conditions. A third cover adds only around 5-15% performance.

Q:Will using gel packs or phase change materials help performance?

Potentially yes. Gel packs can be placed on top of the product or in stitched pockets on reusable blankets to provide an additional barrier against direct sunlight.
