Chimney caulk

Chimney insulation is necessary to assure warm air doesn’t escape the home and cold air stays outside. This way you will save energy  and improve the effectiveness of the chimney. Using blankets, ready mix or wrap kit are all effective ways of insulating a chimney.

Probably the easiest insulating solution is the vermiculite-based insulation which must be mixed with water and poured down the chimney.

Assistance

Having someone to help you through the insulating process is crucial. When trying to hoist the insulation liner down the chimney, you must have an assistant at the bottom of the chimney that will guide you so that you don’t damage the liner or the chimney in the process.

Insulating

Check the house for drafts and cold air infiltration. Inspect pipes, windows, doors and crawl spaces. The overall effectiveness of the insulation will be affected by these gaps.

Measurements

The liner must be extended 1 foot to match the height of the chimney. Measure the right dimensions needed. Be sure to recheck the measurements before you cut the liner.

Foil tape

To tape the insulation seem you have to use one piece of tape for each foot of insulation fabric. When you are done taping, wrap the liner and insulation in mesh.

Caulk and brick

You have to caulk the chimney crown. Before securing the top plate of the liner at the top of the chimney, you must caulk it, then secure it in place. The liner at the bottom of the chimney must connect the fireplace with the chimney itself. To secure and insulate this connection, use metal bands, tar or bricks.
