Workshop Insulation

[Jamie]

To minimise damp and condensation in my new wooden garage, I am considering boarding it out and using foil backed bubble wrap between the wall and board. I shall do the same on the roof with some sort of rubber floor covering. Has anyone else done this and, if so, was it effective? There will still be air flow under the doors. I know that it will not be as effective as Kingspan or Rockwall.
