Sound Insulation for Timber Frame Building
Part E Floors • Walls • Optional Floors • Ceilings

  
 

Part E Building Regulation Compliance

  

For general floor improvement options see Soundproofing Floors

Flanking Details:
All acoustic floors and walls are susceptible to flanking noise via flanking paths which may need treating, particularly lightweight block walls.

Floor and Wall Assembly


  
 

Walls
(Min. 50dB with Phonewell® directly to stud on one side only)

  
For general Wall improvement options see Soundproofing Walls
 

Timber Frame Wall
Single Stud Wall
One Phonewell® layer on one side only brings 36dB (Rw, -4Ctr) and an overall reduction of 50dB!
An Airborne reduction of 60dB+ is achievable when Phonewell is on both sides.
Easy fitting and easy services installation.

 Timber Frame Twin Wall
Twin Stud Wall (50mm min. gap)
One Phonewell® layer to one side only brings 36dB (Rw, -4Ctr) insulation and 1200kg/m3 density.
Isolated twin frames are only necessary for acoustically critical applications.		  
  Decoupled on Resilient Bars
 Additional Plasterboard Layer
  
 


Floors

  
For general floor improvement options see Soundproofing Floors
  Timber Floor with No Cavity Insulation
The Open Cavity System
For applications not requiring Thermal Cavity Insulation.
For simple retrofitting over the sub-deck
with an unknown cavity.

 Timber Floor with Cavity Insulation
The Thermal Cavity System
For applications requiring additional
Thermal Cavity Insulation. The standard first floor in England. *Tests undertaken with 7mm hard laminate floor covering!
Airborne (Rw + Ctr)
Impact (Lnw)
58dB
60dB
 
 

Timber Floor with Double Impact

Timber Floor Batten System

  
  The Dual Impact & Airborne System
For applications requiring additional
Impact Insulation down to 56dB (Lnw).
The lower the result the better!		 The Batten System
For applications requiring extensive
sound insulation and ease of fitting services. Phonewell® strips can be laid under the battens to provide dual impact. Note standard inexpensive kiln dried timber can be used for the battens.		  

Ceilings
For general Ceiling improvement options see Soundproofing Ceilings
 


Timber Ceiling
Retrofitting
Used when retrofitting where access to the floor above is not possible, eg. multi storey apartments. One Phonewell® layer brings 36dB (Rw, -4Ctr) insulation.
