How do you cap the outside wall where the thimble goes through?
By Kevin E. - Fireplace Specialist on December 22, 2011
Answer:This thimble is used when passing stovepipe through a combustible wall into a masonry chimney. The stovepipe will pass through the center of this thimble and terminate even with the inside of the masonry flue. It is not designed to provide passage from inside the home to the exterior.

Do you have a thimble that can be used in thicker walls than 8.5 in?
By Collin C. - NFI Master Hearth Professional on December 4, 2013
Answer:For passing through a single wall stovepipe, no. Our standard thimbles for Class A chimney can be split into two sections, but this thimble must not be split, as it will loose its insulating qualities.
