FORMER PROCEDURES USED FOR CHIMNEY LINING |
FORMER PROCEDURES USED FOR CHIMNEY LINING
For decades the following methods have been used for lining chimneys:
 |
INTERNAL PLASTERING
Plastering the inside wall of the chimney
| + |
Corrosion resistant |
| - |
Cracks, not air-tight |
| - |
Not suitable for use in tall chimneys with a large diameter |
|
FLEXIBLE STAINLESS STEEL TUBES
| + |
Wall thickness 0,2-0,3 mm |
| - |
Corrodible |
| - |
Easy to damage during insertion |
| + |
Also available on long sizes |
| - |
Only circular cross-section |
| - |
Not manufactured in large diameters |
|
|
 |
| |
 |
RIGID, STAINLESS STEEL TUBES
| + - |
Corrosion resistance depends on the type |
| + - |
The period of guarantee is generally 10 years |
| - |
Manufactured in one-metre pieces |
| - |
When inserting into the chimney, the pieces must be pushed together |
| - |
Its air-tightness is uncertain because of the joints |
| - |
It can only be installed into distorted chimneys by demolishing the wall |
| - |
Only manufactured with circular diameters |
| - |
Not suitable for use in tall chimneys with a large diameter |
| + |
Its advantage is good heat resistance |
ALUMINIUM TUBES
Rigid and flexible type
| - |
Not corrosion resistant |
| - |
Unsuitable for chimney lining |
|
 |
|
|
|
|
| |
 |
CERAMIC TUBES
| - |
Manufactured in short pieces |
| + |
Excellent corrosion resistance and heat resistance |
| - |
Unstable at joints |
| - |
Not manufactured with large diameters |
| - |
Not suitable for subsequent lining |
| - |
Not suitable for distorted chimneys |
