Rigid foam insulation

To have an energy efficient house and operate the chimney safer you need to insulate it. Because usually builders don’t make insulated chimneys you will need to install an insulated chimney liner inside your flue.

The buildings are usually built having the chimney on an outside wall.

The problem lies with older chimneys that are not properly insulated. Having the chimney on an outside wall is sucking the heat from the house, in the case of a bricks and mortar chimney with a clay tile flue liner.
To have an adequately insulated chimney you need to have it in the building’s interior, this way avoiding all the energy loss that occurs when you have it on the exterior. Still, you have to deal with draft and creosote buildup. Because of the cold air that gets in contact with the top of the chimney, combustion products will condensate and produce a risky creosote buildup. On the other side, getting in contact with warm air also produces downdrafts, difficulty lighting fire, and smoke access in the interior of the building.

The easiest insulation method is using a metal chimney liner inside the flue. You can wither wrap the liner with fireproof insulation first or you can install the liner first. For wood, oil and coal it is recommended to use stainless steel and for gas you can use aluminum.

The insulation is immediately recognized, with an easier lightning fire or cleaner wood burning. The most important thing is that heat won’t leave the house as it used to, and you will feel the warmth a longer period, even when the chimney is not working.

The investment you make on this will repay itself in time.
