Isokern Leca (50 Litre)
The Isokern Leca is a flue liner insulation, ideal for use with the Isokern Liners and for relining an existing masonry chimney.
Isokern Leca Insulation provides vastly improved draught and improved fuel economy.
The Isokern Leca Mix is the perfect backfill for chimneys and voids. The Leca insulation mix is poured down the chimney to surround the liners, giving them support and insulation.
