Description
Part E Ceiling Soundproofing Kit
Use the Part E Ceiling Kit to comply with Building Regulations Part E. Using this system you will ensure your ceilings achieve the required level of sound insulation required in approved document Part E for the resistance to the passage of sound.
Part E ceiling kit combines all the necessary products you will need for new build and conversion projects to meet the current guidelines for airborne sound reduction.
Part E Building Regulation Requirements
| Value in dB | Dwellings formed by material change of use | ||
|---|---|---|---|
| Walls, floors and stairs | Airborne Sound Insulation DnT,w + Ctr (Minimum value) | 45 dB | 43 dB |
| Floors and Stairs | Impact Sound Insulation L’nT,w (Maximum values) | 62 dB | 64 dB |

Materials supplied with this kit include
- Acoustic Insulation 100mm/60kg/m³ 1200mm x 600mm slabs
- Soundbreaker bars 3m lengths
- 12.5mm Acoustic plasterboard 240mm x1200mm
This system of soundproofing ceilings is suitable for properties that have timber floor joists with a cavity. Insert the 100mm acoustic insulation slabs between the joists, ensure the area is completely filled. Soundbreaker bars are then attached perpendicular to the joists centred between 350-400mm apart. Finally attach the two layers of 12.5mm acoustic plasterboard to the soundbreraker bars.The double boarding the ceiling with two layers of 12.5mm acoustic plasterboard will give you one hour fire protection.

Ensure your project meets Part E requirements for airborne and impact noise
It is important to note that in a majority of developments the requirements will be for a sound test for airborne and impact sound. You will need to consider whether the separating structure will achieve the required sound insulation for both airborne as well as impact? Most properties would require to have not only the ceilings treated with this type of solution, but would also require a solution on the floor above.
The best way to treat impact sound is at the source, in most cases this means adding a resilient layer to the floor. the best methods of achieving this, and to ensure compliance with Part E is to use either an acoustic mat over the floor or install a floating floor. Floating floor solutions can be installed over an existing floor or as a direct to joist solution if the flooring has been removed.
Solutions to combine with the Part E Ceiling Kit to pass Building Regulations Part E
You can view our full range of floor soundproofing products here. The floor solution you use will be determined by factors such as the existing sub-floor, has the floor been removed as part of the work, what is the limit to the thickness of the soundproofing you can lay on the floor? knowing what the floor finish will be will also have a bearing on the type of soundproof flooring you can use.
