Chimney Insulation

Chimney Insulation

Chimney insulation is an excellent solution if you are struggling with the effects of a cold chimney. This often happens if your chimney is built on an external wall, is too big for the flue liner you are using or your chimney stack is particularly tall. This can result in condensation forming on the liner which prevents a good draw of hot air and gases.

The good news is that installing flue insulation can also be incredibly easy! Here at Trade Price Flues we stock some of the best chimney liner insulation products, including fibre glass ThermaFlue sleeves and bags of vermiculite for insulating flexible flue liners.

So, don’t struggle with a cold chimney - shop chimney insulation materials online today at Trade Price Flues for the best deals!
