Description Order dB-Bloc Online Now!
dB-Bloc is a thin mass loaded vinyl sound barrier material designed to layer behind drywall and other finished wall or ceiling surfaces to help combat against the bleed of noise transmitting through a common surface. It is shippedin rolls measuring 54" x 30', covering 135 sq feet per roll. This sound deadening material is designed as sound insulation for blocking noise transmitting through common walls. dB-Bloc measures just 1/8" thick, but weighs more than 1 pound per square foot to produce the density required for a soundproof wall. dB-Bloc will impair a wall's ability to vibrate to reduce sound transmission. An ideal treatment for combating sound bleed in thin walls between loud neighbors or room isolation in any residential or commercial setting. This mass loaded vinyl is shipped in 30' rolls measuring 54" in width. Each roll will cover 135 square feet and weigh nearly 150 pounds.
Note! Luxury grade ratings for sound bleed through a common wall will carry an STC rating of 55-60. A standard wall will carry an average STC rating of 38-40. By applying dB-Bloc and a disconnected framing technique to a standard wall, average STC ratings of 55-60 can be triggered. Also note that NetWell Noise Control is not responsible for the misuse or mis-installation of this prouduct. Mass loaded vinyl is designed to be layered behind a fire rated wall (drywall), and not surface mounted exposed to the room.
Tips
This is a thin, weighted mass loaded vinyl material designed to help deaden the transmission of noise through a common surface. The standard treatment is to layer this material behind wall or ceiling surfaces to serve as a weighted membrane that will help the surface resonate less and combat the bleed of noise. This product weighs 150 pounds for a 54" x 30' roll. Due to its weight, do not rely on adhesive when installing. Your best bet is to anchor the vinyl mechanically using a staple gun, sheetrock screw, etc. For larger and/or taller wall treatments, hang dB-Bloc vertically.
If you are applying this to a studded wall, follow the framing techniques outlined in the Walls section of our Applications Guide to create a disconnection in your assembly that will force your vibration to collapse structurally. For double wall or staggered studs, staple this material direct to the face of your studs and drywall over. For treating a finished surface, staple this material to your drywall, apply a set of horizontal firring strips or resilient channels, and a new layer of drywall. For wall treatments, your firring strips should run horizontal up the wall, for ceiling treatments, anchor the strips perpendicular to the direction of the ceiling joists. Both treatments are shown here:

Cover 100% of your common surface with this material. Remember that anywhere you leave exposed, the noise will know to travel the path of least resistance and bleed out, partially decaying your overall transmission loss results. Overlap the seams of this material by 2" to help combat the bleed through the seams. ISO Clips are available for those opting for mechanical hat channels to create a partial disconnect, otherwise standard wooden or metal firring strips will work fine. If you are treating a common wall made of concrete block, reverse the treatment and place the firring strips or channel system up first, then your dB-Bloc and your drywall. Remember that dB-Bloc is not designed to suspend by its own weight, and needs structure over the top of it to brace it in place. See our dB-Drapes if you're interested in the reinforced version that can suspend by its own weight.
