What is the best way to soundproof a wall?

Are you constructing a new home, considering remodeling or finishing a basement; adding improvement is a great value-added and the best is to soundproof a wall.

The soundproofed walls promote your living experience every day. The rooms that created irritating noise offers a relaxing treat as the noise is isolated. Soundproofing a wall need not be costly, but there is a need to set expectations. However, a professional touch is impossible, but you can always consider DIY soundproofing walls and save money.

Here are a few helpful steps to soundproof a wall and to enjoy pleasing results within budget.

Organize the wall cavity

Clearing the wall cavities is possible if you are ready to do the insulation and sealant job. Remodeling a room means you must take the existing drywall down and eliminate the insulation. Space should be cleared. This is to be done only to the room you wish to soundproof to have isolation of the room. 

Now note the electrical wires, boxes, pipes locations and also see if there is any other obstruction. Fit around these objects the required insulation.

 Choose proper materials for soundproofing

Choosing a quality material is essential to ensure soundproofing so that it fills all the cavities.  Consider using fiberglass products as they are a good option. You can also buy green glue sealant and noise proofing compound. This will decouple partially and bond the drywall dual- layer panels. Likewise, the sealant fills the open gaps or cracks so that sound does not leak out.  You may apply these products using a caulking gun.

 Seal air gaps

There is a need to look for air gaps carefully. On finding a gap enveloping an electrical outlet or so, you may apply the glue sealant and seal it. Also, do not miss the insulation edges and if you find any space, fill it with a sealant. Fill the air gaps so that the sound paths are eliminated. This will ensure no unwanted noise leaking in or from the room.

 Install insulation batts

When the walls and materials are ready, you may fill the cavities with insulation. Air gaps are noise transmitters and they weaken the soundproof walls performance.  Covering or filling the gaps is essential and you can press the insulation batts between studs so that there is no air gap.

Encountering obstructions are common such as electrical wires or outlets. If so, use a utility or bread knife and create cutouts. Once you do that you can see a gap, now seat it up tightly. The pipes and wires also should be checked to make a v notch. This will ensure a great fit.

 Put Up New Drywall

 There are several options and to consider soundproofing you may pursue as per your budget.

  • Firstly, you may put again standard drywall, but bear in mind the noise may not reduce dramatically.
  • Second, applying glue layer on the first drywall and sandwiching over it a second layer helps. The seams should be lined up or else it will create another pathway for the sound to enter. The compound works between the sheetrock two layers as a dampening agent.
  • Third, decouple from the stud wall the sheetrock to remove the vibrations and thus prevent noise transmissions. You may screw the glue clip to the studs and snap hat channels to the clips. Screw the sheetrock to the channel and complete it.
  • Fourth, buy soundproofing drywall engineered especially. These are composite panels of sheetrock having gypsum composition as outer layers sandwiched on the sheet metal. You can also consider other dense materials.

Finishing Touches

Check the drywall base that you have installed just now. Apply the soundproofing sealant as a bead. Also, apply in all the small spaces such as the window and door frames. This sealant will be slightly flexible and help the sound to stop from passing between sheetrock and frame.

You may create soundproofing walls by using the glue sealing compound in the sheetrock second layer. This compound will isolate noise and it is recommended to look for the best ways to soundproof a wall that need not be complicated or super expensive. Considering simple materials to install throughout the room walls is enough to get the job done.
