ABSTRACT
This chapter provides information on the need to prevent sound transmission through areas which include the existing structure, separating wall, new floor and new internal walls. Although not all the proposals within the Building Regulations are compulsory with regard to sound transmission, when you are creating a loft conversion the materials required to achieve the standards are normally already on site and, if they are installed correctly, the end result improves the living environment once the work is completed. There are not many alterations that can be made to the existing structure to improve impact and airborne sound without extensive refurbishment work taking place. If the property that is being converted was built post July 2003 the separating wall will have been constructed in accordance with the regulations and no further action is required. The guidance below is divided into two sections according to whether or not a separating wall is present.
