Hearth design / insulation
Confused by all the options!
Do I need reinforced concrete slab, then vermiculite/concrete layer, then FB board or is that overkill for UK?
Some plans show 6" of FB board - is that an alternative for just concrete slab without the vermiculite/concrete?
All advice appreciated!
