RapidTHAW™ ground thawing blankets are the most economical heated blankets available on the market today. Wattage = HEAT. These electrically heated blankets (in some cases) are double the wattage per sq. ft. of other brands. RapidTHAW™ is offered exclusively by Heat Authority and is also the most affordable heated construction blanket available. RapidTHAW™ blankets are superior in every detail. Weather-proof, Water-resistant, Tough-Rugged Construction helps them to stand out from the pack.


RapidTHAW™ blankets will heat up to 150°F, making them the ideal choice for thawing quickly and safely. Additional insulation placed on top of the blanket will reduce the effects of wind and cold and give maximum results.
