The estimated soundproofing performance of the stud partitions shown above are for partitions with no holes and all joints properly sealed. The sound insulation performance indicated may vary from site to site and should only be used as a guide.
The soundproofed wall shown in the detail below has an approx 87% reduction in sound transmission and complies with the requirements of the latest Building Regulations. It is therefore, ideal for insulating walls separating stairs and hallways where space is at a premium.
