The Top Insert Sleeve Ø 150 is an essential component in the MI-FLEX range of chimney accessories. Specifically designed for use with MI-FLEX 316 and 904 flexible flue liners, this sleeve ensures a secure and stable fit at the top of your chimney. The product complies with Building Regulations Document J, requiring that flexible flue liners be enclosed within masonry chimneys, and supports appliances with temperatures up to 600°C (T600 designation).
Suitable for use with wood (less than 20% moisture), smokeless coal, gas, and oil appliances, the sleeve provides a reliable, durable, and weatherproof solution. When used in conjunction with the Top Plate and Top Clamp, it effectively distributes the vertical weight of the flue liner, maintaining the integrity of the chimney system. Easy to maintain, the system should be swept at least twice a year to ensure ongoing efficiency and safety.
