Celotex insulation - used (Bear Flat)

I have just dismantled a garden building and this insulation was under the floor. It is a bit grubby but perfectly functional. 6 large pieces 240cm x 57cm x 2.5cm. Two have small bits cut out of the middle - see photos. Also 6 small pieces approx 57cm x 30cm x 2.5cm. Would be ideal to insulate a shed. If interested let me know when you can collect.
