Thermoblocker. The Thermoblocker takes the ‘space blanket’ concept a step further. The top reflective layer returns nearly 80% of the radiant heat from the animal. Any heat that passes through is slowed by insulating bubble wrap and kept in the material by the second reflective layer. Almost no heat passes through the Thermoblocker. The padding adds comfort and is designed to fit surgery tables. Easy to clean. Size: 115 x 60cm.
