I see what you mean. The roof and walls are insulated with a combination of polystyrene sheeting and bubblewrap, I was on a tight budget, but it seems to have worked. The wall cavity was about 2 1/2 inches which was jam packed with insulation.

I dont want to overspend on floor insulation if its not necessary, the cheapest option would be the best for me, ive already spent way too much on the workshop as it is.

This insulated MDF sounds good, i will have to look out for that. It would be ideal.
