perimetre insulation

L driver

Hello,
When installing edge insulation strip is it best to leave it high and cut off the excess when the screed is dry, just in case the levels are a bit off?

Poor Uncle Tom

No, it is usual to cut it a couple of mm short to allow the screed to be levelled with the float screed on the leaf behind the edge insulation.

Thinking of going with a liquid self leveling screed so there won't be much floating

no, not really.... your wall insulation is a continuous layer at this point...

at the floor it stops and creates a thermal bridge.
