Hi Rob 1 st question is who have fitted hard board on walls and what was a reason to fit? I presume it is not fitted in a house;-) If it's in a garage or shed you can over boarded then skim over which will give you an extra insulation too;) For a cost of fitting please go to our main website then 3 trades will contact you to obtain a quote. I hope this can help Best regards Rafal Plumbing and Heating Solutions Wyke Bradford
