This chimney liner is not insulated. In order for a UL listing (safety testing) to be valid on any brand of chimney liner, it must be insulated when installed into the chimney. This means either purchasing a pre-insulated liner or insulating the liner on the job site. Insulating materials can be purchased separately from Obadiah's. You can also purchase a pre-insulated liner from Obadiah's. Please contact Obadiah's if you have questions on the various liners that are available.
