  • Preferred Installation
  • Alternative Installation
The preferred installation procedure is to add dB-3® PRO to the backside of the drywall and install as per typical drywall installation techniques.

STEP 1: Apply acoustical caulk on top and bottom of wall system to prevent noise leakage through the frame wall system.

Step 2: Staple or glue dB-3® PRO to the backside of the drywall.

STEP 3: Hang and install drywall as per standard installation techniques

STEP 4: Apply acoustical caulk along the joints to ensure a proper seal once drywall is installed.

STEP 5: Add adjacent layer of drywall and repeat.
Alternative Installation Technique (apply on wall framing)

STEP 1: Apply acoustical caulk on top and bottom of wall system to prevent noise leakage through the frame wall system.

Step 2: Staple or adhere dB-3® PRO to the wall framing. For wood studs, nails or staples can be used. For metal wall systems, use a double sided tape on both the horizontal and vertical studs to adhere dB-3® .

STEP 3: Align dB-3® on the VERTICAL stud. Position the edge of dB-3® Pro in the center of the stud 48” away from the corner. Nail, staple or use adhesive to secure dB-3® in vertical alignment.

STEP 4: continue to nail, staple or adhere this dB-3® layer until it is secured and flush to the wall system.

STEP 5: On the adjacent sheet, position the dB-3® PRO layer along the exposed surface of the vertical stud where the other sheet resides on. DO NOT OVERLAP THE SEAMS. This will enable the finished drywall layer to have a flush finish.

STEP 6: Apply acoustical sealant on all exposed joints and electrical outlets to prevent any noise leakage from one room to another.
* 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®.
