Item# EFS005C

Equipment-less Foam Sealant™, or EFS™, shaft bags are generally 1/3rd cubic yard, self-contained two-part bags of our flagship 24-005 system.
This 100% water blown system contains no HFCs, CFCs or HCFCs and has a global warming potential (GWP) of 1.
This size, weighing about 25 pounds when packaged, has proven over the years to be the optimum size for transportation,
handling and mixing, including moving by back pack, pack animal or helicopter.

EFS™ bags can be stored at virtually any temperature and altitude, just keep them dry and out of direct sunlight.
Caching EFS™ in the winter for spring/early summer use can greatly ease transportation costs
