The Mi-Flexwrap 10m Kit is an essential insulation solution designed for flue liners, particularly useful in large, open chimneys or exposed positions. It significantly reduces the likelihood of condensation by maintaining the internal temperature of the flue. Constructed from non-combustible material, Mi-Flexwrap can operate continuously at temperatures up to 550°C, ensuring durability and safety.

The 12mm thick blanket easily conforms to bends and can be adapted for liners up to 200mm in diameter. Installation is a breeze: just wrap the flue liner with the Mi-Flexwrap, seal the joints with the included 12m aluminium tape, and secure with the 20 aluminium bands spaced every 500mm. For those precise cuts, a Stanley knife does the job perfectly.
