| 摘要 |
The invention is directed to improvement in thermal covers used to protect piping, liquid transmission, backflow prevention systems, etc. The improved thermal cover includes an insulated pad, a heat barrier and wrapper to hold the insulated pad configured in a specific fashion so as to improve freezing resistance and/or reduction of damage due to excessive heat. Padlocks, ties, etc. secure a thermal cover by means of grommets to an underlying piping, liquid transmission, backflow prevention system, etc. component. Removal of a tie permits access to the underlying components. Padlocks provide security for the thermal cover simultaneously with the access afforded due to removal of a tie. One or more foil layers further enhance protection against radiant heat loss. The combination of the one or more components of foil backing attached to structurally strong foam contributes to the thermal cover's ability to maintain its shape and it's effectiveness over time.
