Installation of dB-3™
Tools needed: razor knife, straight edge and measuring tape
Instructions: Click on each of the steps below
  • Step 1
  • Step 2
  • Step 3
  • Step 4
  • Step 5
Install dB-3™ horizontally
or vertically according to the installer's preference

Staple, nail or glue
to framing
Overlap seams by approximately 1” to 2”
to ensure minimal
noise leakage.

Nail, screw adhere to the sub-surface.
Add a layer of acoustical caulk / adhesive to further seam the layers together.

Goal is to avoid any and all leaks to maximize sound isolation.
Continue to overlap
and seam multiple dB-3™ sheets together
Complete job.

Note duct tape is not necessary as it is already seamed / adhered together. This was to outline the multiple sheets and to offer additional techniques to ensure limited leakage throughout the wall system.
* Note: There are two types of noise sources — structure-borne noise and airborne noise. dB-3™ Pro is designed to combat airborne noise. Although dB-3™ will help isolate the wallboard to the studs and reduce some of the structure-borne noise, the structure-borne paths may need special attention to reduce noise traveling from one wallboard, through screws and studs and radiating out the other side. Use of resilient channel (RS) will significantly improve this noise path, further increasing the overall value and noise isolation characteristics of dB-3™.
