Chimney Liner Options Part Eight

This is because the moisture created in wood burning fireplaces mixes with the creosote and this becomes a gas which rises out of the chimney. However – it really can’t hurt and can benefit you in other ways.
Finally there’s one more reason that insulation is a good idea for your chimney liner – and that’s that having a hot fire and a cold chimney will cause down drafts. This is because air rises – meaning that the air pressure around your fire is lower. In other words there’s a ‘pocket’ of air around your fire where much of the air has risen away, and if you don’t have insulation for your liner, the cold air will rush in to fill this gap (this is the same process that causes wind – wherein the warm earth heated by the sun has the same effect as a fireplace).
If you don’t get insulation and good flue liners then, you will find that the wind rushes in and blows the fire while also making your room colder. Again this will also create a lot of noise and be upsetting for you to listen too.

Thus when it is cold it will get very cold and that will mean that it will attract condensation – which is a by-product of the burning of your fires (hence the term ‘non condensing furnace’). This will attach onto your chimney liner and this is a serious problem as condensation is acidic and highly corrosive – meaning it would eat away at the liner and eventually completely deteriorate it.
Worse, if you get condensation on your chimney liner, then you will likely also get creosote on your liner and this is very danger as creosote is a dangerously flammable substance which can cause chimney fires. The colder your chimney is, the more creosote will stick to it, and the more creosote is on your chimney, the colder it will become.
However bear in mind that this insulation is more crucial for wood burning chimney liner or coal chimney liner. For gas or oil burning fireplaces you will usually be fine with the flue liner on its own.

Chimney Liner Options Part Six

However if you really want chimney liner that you can rely on then it is important to put a little extra work into it yourself, and specifically this means getting insulation for your chimney sweep liner.
But bearing in mind that the role of the chimney liner is essentially to provide insulation, why do you also need insulation for that itself? Well chimney sweep liner is actually a highly essential example of chimney supplies for several reasons.
First of all, if you have stainless steel chimney liners you might find that when the wind blows very heavily the liners rattle and shape and this can make an awful racket – in fact it will be enough to wake you up and it won’t be particularly conducive to rest or relaxation which is what most of us use our fireplaces for.
Another reason you need insulation is to protect your liner. Whether you use foil liners, stainless steel liners or ceramic the problem with this is that it is a conductor and not an insulator.
