SFL improve carbon footprint and UK-to-UK distribution with new Flexible liner manufacturing capabilities.

10 February 2025

SFL are proud to announce a significant expansion in their manufacturing capabilities with the introduction of flexible liner production at their 120,000 sq ft facility in Barnstable, Devon.

This new production line strengthens the Residential division of the business, allowing for the manufacture of flexible liners ranging from 80mm to 250mm in diameter, with multiple performance characteristics and advantages.

Jason Lee, Technical & Engineering Manager at SFL, commented on the development:

“The new flexible liner machines will enable SFL to produce 0.1mm and 0.12mm 316 stainless steel, as well as 0.1mm 904 stainless steel twin-wall flexible liners. This expansion complements our existing product range. Having the flex production line based here in the UK allows us to maintain strict quality control. Every time production begins, or when we adjust the diameter or introduce a new coil, we conduct a comprehensive series of tests in accordance with EN 1856 Part 2. These tests include leakage, torsion, tensile, and various dimensional checks, all of which are integral to our rigorous quality assurance process.”

Key Features of the New Flexible Liner Production Line:

• Production of double-wall flexible liners for chimney and ventilation systems
• Available in pre-coiled lengths ranging from 6m to 50m
• Suitable for positive pressure and condensing applications (P1 W)
• Manufactured from a single strip of material for optimal durability
• Fully computerised and programmable production process
• Diameters from 80mm to 250mm
• Tested and CE-marked in compliance with EN 1856 Part 2

Andy Dimond, National Sales and Marketing Manager for the UK & Ireland, remarked on the strategic investment:
“Being able to offer UK-based manufacturing is essential to our continued success, and reducing our carbon footprint is a vital part of our broader quality control strategy. At SFL, we are immensely proud of our British manufacturing heritage. This investment in state-of-the-art production equipment, alongside our extensive R&D capabilities, ensures that we are continuously innovating to meet the latest UK and European standards.”

In addition to the new production line, SFL boast a comprehensive R&D centre, dedicated to continuous product development and testing to ensure compliance with the most up-to-date regulatory requirements.
