Aluminum Gas Relining

Selkirk Flexi-Liner

Selkirk Flexi-Liner is super flexible which makes installation easy, even in challenging chimneys.  We recommend insulating this liner with Flexi-Sleeve to further minimize condensation or contact with chimney contaminants. 

The outside diameter is approximately 3/8" larger than its inside diameter.
