3M™ Expantrol Flexible Intumescent Strip E-FIS is an intumescent tape designed to seal the air spaces between doors, frames and glass to help prevent the spread of fire, smoke, toxic gases and other byproducts from penetrating into adjacent areas. Intumescent material expands and forms a hard char when exposed to heat. This flexible, conformable strip can be quickly cut to required sizes.
