Chimney Lining

Why chimney lining?


1) The liner protects the house from heat transfer to combustibles. In the NBS tests, unlined chimneys allowed heat to move through the chimney so rapidly that the adjacent woodwork caught fire in only 3 1/2 hours.

2) Liners protect the masonry from the corrosive byproducts of combustion.
In the tests it was determined that if the flue gases were allowed to penetrate to the brick and mortar, the result would be a reduction in the usable life of the chimney.
The flue gases are acidic in nature and literally eat away at the mortar joints from inside the chimney. As the mortar joints erode, heat transfers more rapidly to the nearby combustibles and dangerous gases such as carbon monoxide can leak into the living areas of the home.

3) Liners provide a correctly sized flue for optimum efficiency of appliances.
Modern wood stoves and gas or oil furnaces require a correctly sized flue to perform properly.
