To stand the best possible chance of passing your sound test in compliance with Approved Document E, it is important not only that you use the right products but also you fit them correctly.

The list below highlights some of the major causes of sound test failure. Please check the read through the list, and where required check off the items one by one so that problems can be solved at the earliest opportunity during the construction phase.

(Some items may not be applicable to your type of construction).

1. Do not directly nail or screw through an Acoustic Floor.
2. If using a Resilient Bar construction ensure that they are installed as per manufacturers recommendations Ensure the insulation fills the whole width of void, also pack around pipe work.
3. Do not directly screw plaster board into joists when using Resilient Bar construction.
4. Ensure that Acoustic floors are fitted with staggered joints.
5. Ensure Acoustic floors are sealed around heating pipes.
6. Ensure all isolation joints are over lapped and taped to floating screed floors.
7. Do not fit carpets or laminated flooring before you have passed the test as this may need to be pulled up prior to the sound test.
8. Ensure that any plasterboard to walls is down to the sub-floor and any gaps sealed with acoustic mastic.
9. Ensure that isolation tape is used around the wall of each room.
10. Ensure plasterboard is installed with staggered layers and all joints are sealed.

16. No building work can take place during tests.
