Flooring - What materials are these?

[NewTo-HandyMan]

Years of leak found recently under the laminated floor. Part of them rotten and can't be used. I am trying to find all the layers above the concrete floor. This is my first attempt.

Any help would be appreciated.

Layer-1 : Fibreglass material ?? - Please hep with the name.
Layer-2: Floor matting ?? - Please help with the name
Layer-3.a : Swan treaded timber : https://www.wickes.co.uk/Wickes-Treated-Sawn-Timber---19-x-38-x-1800mm/p/235009 - Am I correct?
Layer-3.b : Polystyrene ?? - Please help with the name
Layer-4 : Floor Board ?? - Please help with the name
Layer-5 : Flooring Underlay - Am I correct?
Layer-6 : Laminated flooring

Thank you!

Reads like an exam!

Looks like someone’s laid a floating floor over the top of concrete...including the old carpet!

It doesn't look like carpet. I see some yellowish rubber / plastic bottom of the material (My door mat also have the yellowish bit). I am not tradesperson, so not sure carpet comes with yellowish rubber / plastic.

agreed.

I’d just rip out lay celotex and float 22mm chipboard on top
