    One of the remaining jobs on our build is to lay a reclaimed parquet floor. I left a healthy amount of floor zone so that we could achieve a polished screed elsewhere, which means I'm now left with 60mm between structural slab and FFL.

    The parquet units are fairly worn so range between 15-20mm. This variance, plus the old tar on the back mean I'm intending to run them through a thicknesser in an attempt to standardise the depth.

    Either way that leaves at least 40mm to make up. We have below-slab insulation to achieve a slab performance of 0.1 W/m²K, so there's no requirement for extra underfloor insulation or heating for that matter, but this is one (albeit expensive) way to make up the levels.

    Does anyone have any other suggestions?

    I'm thinking a liquid applied solution might be best since we have a joint around the perimeter between the CLT walls and floor which has shrunk slightly in places. It's been air tested already (taped on the outer face), but filling this and taking out the grout 'step' would be an extra bonus.

    How about 1 or 2 layers of either flooring grade chipboard or OSB using different thicknesses to make up to the required thickness
