Insulated floor boarding?

[AGT]

What’s the sub floor?

Self levelling compound may be an easy solution?

Wouldn't that have almost zero insulating properties?

Bit thick for self-levelling ?

You can layer it up.

Will it upset the last riser? Like, was it left because of that different first/last step?

Will 20mm upset the front door clearance?

Thanks lads, we are good up to give or take a mm, 20mm across the whole hall. Front door will clear too at that height. We are off up to see a carpet fella tomorrow and I'll get the underlay and carpet heights.

I am thinking 6mm xps insulation boards, 5mm engineered board screwed thru to fix , then 5mm underlay, 5mm carpet. The main thing is the compressive strength of the lowest poly board. The engineered board on top should spread the load well (I hope).

Insulation between a home and the outside world including ventilated voids in my opinion needs to be a few hundred millimetres thick.

Sadly that's not practical in this case. Although we have noticed the difference in the newer build and being surrounded on 5 sides of the apartment box shape by other properties. Only one face is externally exposed.

When we were there over Christmas one bathroom towel rail was on and that pretty much heated the whole place to an acceptable lower limit with spot heating later in evening. Amazing how the 'kids' suddenly develop frugality when the bill is theirs to pay!

We are going to be boring and use underlays to bring the hallway up to the level of the surrounding rooms. In the lounge we are going for a quality carpet with thick underlay built in and that will be glued down. This will save me the job of bursting off the lounge edging beading for grippers and repainting the skirting boards. I'm all for that!
