DESCRIPTION Double layered flexible flue liner composed by a corrugated outer wall and a smooth inner wall with circular cross-section; material is AISI 316L and thickness 0,10+0,10 mm or 0,12+0,12 mm. Its manufacture is accomplished by a process of quadruple seaming and contemporary shaping of a single superimposed sheet, ensuring an increased resistance to tightness and acid condensate if compared to conventional 2 seams flexible systems. Thanks to its 4 seams security is doubled thus making the flue liner resistant to helical disjunction during cutting and lining. Good mechanical and functional characteristics both in terms of resistance to traction and compression are ensured by its structure.

USE Gas exhausts release to atmosphere from thermal appliances. Installation of flue pipes, liners, collectors and chimneys for relining for blow, pressurized or natural draught heaters and boilers. Suitable for type “B” appliances fireplaces and wood stoves.
