Double Wall Lining for 180mm Stove Pipe, 2mm, FIREFIX R180/WD (Ecost customer return)

Double wall lining for 180mm stove pipe, model FIREFIX R180/WD, is an internal sleeve intended for use in wood-burning stove flue systems. Manufactured with a 2 mm wall thickness, the lining fits pipes with a nominal diameter of 180 mm and serves as a durable inner surface to guide smoke and exhaust gases while contributing to thermal isolation and mechanical protection of the flue. This product is intended for residential chimney repairs, retrofits or where an internal lining is required to improve performance of existing stove pipe sections.

Advantages

The double wall construction and 2 mm material thickness provide enhanced resistance to mechanical wear and corrosion compared with single-thickness liners. As an internal lining, it helps maintain a smooth passage for flue gases, reducing areas where soot can accumulate and facilitating easier cleaning. The lining improves thermal isolation within the pipe assembly, which can contribute to more stable draft and more efficient combustion in wood-burning stoves. Its form factor is compatible with standard 180 mm stove pipe sections, enabling straightforward installation in many residential setups.

Suitable for

• Repairing damaged sections of 180 mm stove pipe
• Upgrading existing flue assemblies to a double wall internal lining
• Improving thermal isolation and exhaust flow in residential wood-burning stoves
• Providing a durable inner surface to reduce soot accumulation and ease cleaning

Key specifications

• Nominal pipe diameter: 180 mm compatible
• Material thickness: 2 mm
• Double wall design intended as internal lining/protective sleeve
• Use case: wood-burning stove flue systems, residential installations
• Function: thermal isolation, durable inner surface for smoke and exhaust

How to use

Measure the internal diameter of the existing stove pipe to confirm compatibility with a 180 mm lining, then slide the lining into the pipe section that requires repair or upgrade. Ensure ends align properly with adjacent pipe sections and maintain correct clearances to combustible materials as required by local building codes. Secure joints and connections according to the stove pipe system design, using suitable clamps, seals or connectors to prevent leaks of combustion gases. After installation, inspect the assembly visually for proper fit and perform a controlled firing to verify draft and function before regular use.

Usage recommendations

Follow local regulations and manufacturer instructions for stove and chimney installations. Have a qualified technician inspect the flue system after installation to confirm safe clearances, adequate draft and proper sealing. Regular visual inspections and routine cleaning of the flue are advised to maintain safety and performance.
