A true chimney is a configuration of usually bricks that go up from the house or business buildings. They will
pull the hot gases and or smoke from boilers, stoves, furnaces or a fireplace out into the air. Romans used tubes
inside the walls to draw smoke from a bakery. Real chimneys only started to pop up in northern Europe around the
twelve century. Then in the late eighteenth century the industrial chimneys were found on the large buildings. The
early chimneys were often made with a simple brick layering. Then the bricks were put around tile liners.
An old chimney can be a fire waiting to happen. If a fireplace does not have proper chimney liner insulation, it
can be disastrous. Most of the chimneys have either terracotta or clay liners and they make up the membrane of the
chimneys. Instead of the smoke and gases adhering to the fireplace wall itself, it goes up through the liner, which
is much safer. Creosote coats the walls of the fireplace and can ignite at any time. Some must and should either
rebuild the fireplace and put in a new liner or maybe just replace the liner.
Chimney liner insulation can be made of stainless steel because it is so flexible it can be turned in a way that
will fit any fireplace. The tubes are placed inside of the existing fireplace once the old one is taken out.
Stainless steel chimney liner insulation will last about twenty five years or so. Although it is cheaper to
install, many still go the way of the tile liners. Some fireplaces do not have these liners so the job would be a
bit easier. Many think that the terracotta liners are better but are expensive to install. But then they will last
up to seventy five to one hundred years.
The chimney liner insulation step is sometimes ignored and it should not be. With the proper insulation it will
allow the liner to heat correctly, permitting for a good draft or flow of air. People that install chimney liners
will use either vermiculite and concrete combination and it is then poured down the flue. This fills in any spaces
between the liner and flue. It is left to harden.
Another way to properly install chimney liner insulation is wrap the liner in a ceramic ‘wool blanket’. This
option requires a smaller liner and it might reduce the draft quality. Installing chimney liner insulation should
only be done by the professionals. Although it only takes an hour or so, if not done right it can lead to a fire.
Flue tiles are good chimney liner insulation. These are used in new constructions and are for the small, short,
straight chimneys.
There are many different styles and sizes of chimney liner insulations. Again this should be left to the
professional but many will do it themselves. There are even kits that can be purchased to help the homeowner to
install the liner properly.
