Hi. Quick question:
I have rigid insulation upstands around the concrete slab in my extension, and am using self-levelling compound on it before laying engineered wood.
Do I trim the insulation and level over it (creating a thin cold bridge to the masonry/bifold frame) or level first and trim at the new level?
I'm wondering how stable the wooden floor will feel at the edges if it's floated over a spongy bit of insulation... I'm not planning to put skirting on that wall, and it's not being plastered either, so the full 25mm will be exposed.
Thanks!
