37. New Build - Scotland BPC

38. New Build - Scotland BPC Sound insulation testing (PCT) is not compulsory Robust Details Scheme is not yet used in Scotland Some BCBs (few of the 32 LAs) ask for PCT

39. New Build – Scotland (FUTURE) BPC What new build regulations we create for sound insulation will impact on our future housing stock and future generations?
