Flooring query

Hi all

Hoping someone can assist...

I have a lounge that is currently wooden floorboards & I need to add insulation, raise floor level and create floating floor for LVT to be fitted.

Builder has suggested the following:
DPC (black membrane)
40mm Celotex
22mm Chipboard
5.5mm Ply
LVT finish

I am just wondering, in terms of fixings, how would I go about fixing the chipboard to the celotex insulation (should this be glued) and how would I then fix the ply to the chipboard (would my best bet be 15 or 20mm staples)?

Thanks in advance for any guidance

If its a floating floor make sure the celotex is laid completely flat and its self weight should suffice with the chipboard above. Thin ply should be glued and nailed to let it set.

Thanks for the response.

Is that glue and nail the the ply to the chipboard or do you mean glue ply joints and then nail to the chipboard?

Thin ply needs to be completely glued to the chipboard, the nails will keep it in place as it dries, a nail gun is probably quickest. Thin square edged ply can't effectively be glued together.

Thank you. I assume standard wood glue is fine for this?

Would probably use pva, this vid is a helpful overview.
