Soundproof Drywall in Meridian, Idaho

Meridian Quality Drywall hangs soundproof drywall in Meridian as an assembly, not as a single specialty sheet. Mass, offset seams, a break in the stud path, and acoustic sealant are the job. Home theaters, offices over garages, and bedrooms on a busy wall are the usual rooms.

Call (208) 382-8431 with the room, the noise source, and how much thickness you can give the wall. We quote a stack.

Soundproof Drywall Options for Meridian Properties

Double 5/8-inch Type X, offset seams

Two layers of 5/8-inch, seams offset, perimeter sealed. More mass. Still a wood-stud path unless we add a break. Good when thickness is tight and the source is speech, not a subwoofer.

Resilient channel or clip-and-hat

A break between the sheet and the stud. The board hangs on channel or clips, not on the stud face. Screws that miss the channel and hit the stud short-circuit the break. That is the detail that makes or ruins this wall.

Staggered-stud or double-stud wall

Two rows of studs or staggered studs on a common plate. Insulation in the cavity. This is the quietest common wood build. It eats floor space. We frame or we hang on framing someone else built.

Retrofit second layer on an existing wall

Offset seams, damping compound between layers if specified, putty pads on boxes, sealant at the floor and lid. We do not leave a gap at the baseboard for sound to walk around.

How We Handle Soundproof Drywall in Meridian

1. Name the source. Speech, HVAC, garage door, or a media room. The source picks the stack.
2. Check thickness and outlets. A stack that buries a box without an extension is a leak.
3. Hang the first layer. Seal the perimeter. Insulation in the cavity if it is open.
4. Channel, clips, or the second layer with offset seams. Screws into the right member only.
5. Tape and finish. Acoustic sealant stays at the perimeter. Joint compound is not sealant.

Materials and Methods

Five-eighths Type X for mass. Specialty laminated sheets when the spec names them. Resilient channel or hat channel and clips. Acoustic sealant. Putty pads. Damping compound between layers when that is in the job. Paper tape and a normal finish on the face layer. ASTM C1396 still applies to the gypsum. STC is a lab number for an assembly, not a brand. We do not promise an STC from a sheet. We hang the stack you asked for.

Sound layers still hang to ASTM C840. Face board is ASTM C1396, often 5/8-inch Type X. Hat channel or resilient channel as the assembly names it. ASTM C475 paper tape on the face. Acoustic sealant at the perimeter. GA-216 fastener rules still apply. A second layer only when the bid says two layers. We do not claim an STC number we did not test.

Outlets are where sound assemblies fail. A box that sits proud, a gap around a ring, or a screw through channel into a stud will leak more noise than the sheet choice. We plan boxes, putty pads, and screw length before the first dense sheet goes up.

Media rooms with cans in the lid need a layout first. Every can is a hole in the mass. We can work around a planned grid. We cannot fix a lid that was punched full of holes after the stack was hung. Say the fixture plan when you call.

What Soundproof Drywall Costs in Meridian

Fixr lists soundproof drywall installed around three dollars fifty-five to seven dollars fifty a square foot, well above standard board. Angi and HomeAdvisor put soundproof material around 1.85 to 3 dollars per square foot for the sheet itself, before the extra labor of channel, a second layer, and sealing. Thickness, clips versus double stud, and fixture counts move a Meridian quote. We quote the assembly. A single dense sheet is a different, lower number.

A garage-to-office stack that ignores the man-door and the HVAC return will still sound like a garage. We seal what we hang. We tell you the door and the duct are still paths. Gypsum cannot close a door leak.

Damping compound between layers is messy and it works only if the second sheet is screwed on the right schedule. Too many screws into the first layer stiffens the sandwich. We follow the compound spec on screw pattern. That pattern is the product.

Baseboard and casing that get caulked to a sealed wall help. A gap at the floor after the carpenter leaves is a leak we can seal if we are still on the job. Tell us when trim is due so the perimeter seal is still accessible.

Soundproof Drywall Questions

Does one layer of dense board soundproof a room?

It helps. It is not a full assembly. Mass, a break in the stud path, insulation, and acoustic sealant at the perimeter do the work. We quote the stack, not a brand name.

Resilient channel or a double stud wall?

Channel is a thinner build. Double stud or staggered stud is a thicker, quieter wall. Access, thickness, and the noise source pick the method. HVAC and outlets can short-circuit either one if we ignore them.

Can you add a second layer on an existing wall?

Yes. Offset the seams, add damping compound if that is in the spec, and seal the perimeter. Outlets get putty pads or a box extension. A second layer that stops short of the floor leaks sound.

What about a media room ceiling?

The lid needs mass too. Channel or clips, a dense sheet, and a sealed perimeter. Recessed cans punch holes in the assembly. We plan fixtures before we hang.
