This booklet gives practical guidance to housebuilders on how to avoid the 'top ten' faults which can affect the sound insulation of party walls, party floors and their flanking constructions. Such faults can and often do lead to failure when constructions are tested to show compliance with Part E of the Building Regulations.

It is therefore important to follow the guidance given. It applies equally to building conversions and new build projects. The various issues dealt with are as follows:

- Precast Concrete Planks
- Plasterboard Partition Head Detail
- Building the Right Thing
- Timber Separating Floors - Floating Floors
- Cavity Masonry Separating Walls - Wall Ties
- Cavity Masonry Walls - Cavity Bridging
