Insulation backfill for flexible flue liners UK - is used to insulate around a flexible chimney liner where you do not want to use Lintertherm. 


This insulation is similar to vermiculite insulation in that the chimney is blocked from the bottom using a register plate and the insulation is then poured around the flexible chimney liner from the top of the chimney. Unlike vermiculite, it will not compress if it gets damp/wet. I much prefer using the linertherm if possible as it is far easier to use and carry.
