Product Description

ICC Insulated Wall Thimble

The ICC insulated wall thimble allows a wood stove to be vented safely through a wall that has combustible materials in it.  IF the wall is pure masonry, then only a rigid piece of stainless steel liner is required.  IF the wall has any type of combustibles within proximity of the vent pipe, then the local building authority will probably want to see an Insulated Thimble installed.  One side of the thimble is black (part that goes in the room) whereas the other will connect to a stainless steel liner system OR the clay tile.
