Laminate Flooring Materials (Knaresborough HG5)

We've just taken up our old laminate flooring (approx 3m x 5m) and have some items which might be useful:

1) 8 rolls plus a few offcuts of underlay, approx 3mm thick
2) Fibre insulation board approx 5mm thick. Quite a few full sheets plus offcuts
3) The laminate flooring itself, pale wood effect. This has been down 20 years so not in the best shape and some pieces we "reluctant" to come up but might be good for something.

Probably going to the tip fairly soon so please respond quickly if any of this is any good to you
