Staggered Stud Wall Vs. Double Stud Wall

Soundproofing is something that many individuals don’t comprehend that well until they begin investigating for a project. It may appear to be a natural cycle, yet there are a few methods to think about relying upon every circumstance. 

There are only two techniques to consider for the people attempting to save a smidgen of cash and make an effort not to pull anything excessively convoluted off. There is the choice to go with a staggered stud wall or a double wall. 

Specific individuals firmly support the two methods, and one may be better than the other by relying upon every individual circumstance. 

Which one is the ideal choice? Here is a more intensive glance at staggered stud wall and double wall choices for soundproofing. After comparing the two, you will be able to settle on a lovely significant choice on what to go with eventually. 

Staggered Stud Wall Construction

A typical wall will have two by four wood utilized for outlining separated by 16 inches. You will connect the 2x4s to the base and top plates. The base and top plates are 4 inches wide also. 

In a staggered wall, the top and base plates are typically 6 inches wide. The upward 24 studs are put then again on each side of the plate. The hole between two staggered studs is 12 inches. 

With a staggered stud wall construction, you will acquire an additional air hole of sluggish air, which is profoundly helpful for sound disconnection. 

Air pits have an enormous effect. Indeed, even an inch of additional air pit will have a ton of impact on soundproofing. 

Why Not Only Have Six Inch Wide Single Studs? 

That was our inquiry at first. The appropriate response is straightforward. 

Above all else, the air cavity of a staggered wall is essentially more extensive than an ordinary single stud wall. It is this hole that is helping us in soundproofing. 

Besides, there is some decoupling occurring in development. If you’ve known about the term decoupling, you realize it essentially implies diminishing the resources between the existing wall and the new wall. 

With decoupling occurring, the exchange of sound vibrations to the external wall is diminished.

Double Stud Wall Construction

It is easy to decide whether a double stud wall or a double wall is two standard outlines combined. 

However, rather than simply nailing them together, we leave a little hole between each wall distinction. We need as much decoupling to happen. 

Thus, we have two casings of 24 studs, each with a hole in the middle. The general thickness of the wall with a two-inch hole, for instance, would be 10 inches. 

Staggered Stud Wall Vs. Double Wall – Performance Comparison 

Having taken in the essential plan contrasts between the two, our next question is which is better for soundproofing? 

STC Of A Staggered Stud Wall 

According to the information, with one layer of 5/8 inch gypsum introduced at one or the other side of the staggered, you would accomplish an STC of 48. 

According to Wikipedia, at STC 45, a noisy speech won’t be perceptible. At 50 STC, you will faintly hear loud music (mid and high frequencies). Along these lines, a staggering wall with 48 STC will segregate loud noise and a touch of loud music. 

STC of Double Stud Wall 

With one layer of 5/8 inch gypsum introduced at one or the other side of the double stud wall, according to information by Soundproofing Company, we get an STC of 60. 

If you return to the Wikipedia page, it says that 60 STC and past is viewed as prevalent soundproofing and that most sounds won’t be discernible. 

Along these lines, the exhibition of a double stud wall is unrivaled. 

Adding Mass and Damping 

Higher STC can be accomplished by adding more drywall, mass, and a damping compound like Green Glue

For a staggered wall, if we somehow managed to include just drywall on every one of the sides, we could accomplish an STC of 58. Furthermore, with Green Glue in the middle of the layers of gypsum, it very well you may knock it up to 62, which is excellent. 

Then again, if we somehow happened to go for the double stud wall, with just the drywall, you can have the STC is 69. Also, Green Glue on the two sides can go up to 73, which is excellent.

Which One Did We Go For 

The double stud wall is unrivaled, no questions. Yet, it occupies a lot of space. The double stud wall would eat into right around two feet for each wall. That adds up to four feet decrease long and one more four feet in the room’s expansiveness. 

With the staggered, we would lose around 10 inches on each wall. That adds up to a deficiency of under two feet on each side. 

Staggered Stud Vs. Double Wall: Which One is Right For You 

If you have space, you ought to go for double-stud walls. The distinction in STC appraisals is a lot. 

A double-stud wall with just one layer of drywall will have about similar STC as a staggered wall with two layers of drywall and Green Glue. 

However, if you cannot stand to forfeit that much space, a staggered stud wall is the best way to go. 

Why Doesn’t Everybody Use Double Wall Construction for Soundproofing? 

It appears to be clear in the test that a double stud wall is a more practical approach for soundproofing. While the tests unquestionably don’t lie, there is the issue of this sort of wall taking up a lot of room. 

There is a cost to pay to shape that sort of room between the two walls. A commonplace double stud will take up around 2 feet, which can essentially lessen the size of a residing region in more modest spots. 

That measure of the room begins to add up, and it very well may be more than the vast majority will forfeit. 

With staggered stud wall development, the space is somewhere around 10 inches to 12 inches mostly. Saving with regards to a foot of the room is absolutely something a great many people can appreciate. 

It boils down to just choosing if that additional piece of soundproofing inclusion merits all that space being eaten up. 

Some Tips on Introducing Staggered Stud Walls or Double Stud Walls

We might want to give you some hints that we are aware of, which you want to remember while introducing a staggered or double stud wall. 

  • Do check with your nearby construction law to check whether you can have 24-inch framing for walls. In certain places, this isn’t permitted. 
  • Ensure that the timber is pressure treated. 
  • You ought to load cavities with free insulation and not firmly stuffed. The protection will keep the wall from resounding and assimilating sound. 
  • Utilize acoustical caulk to seal holes where the drywall meets the floor and roof. 
  • Dont disregard the floors and roofs. In case nothing is done with regards to them, you will, have issues inferable from flanking. 
  • Dont fail to remember the windows, entryways, and air vents. These are failure points, taking everything into account. 
  • Distinguish the trouble spots which are making sound release the most. It is the thing that you ought to take care of before undertaking any soundproofing project. 


To sum up, a double stud wall performs better compared to a staggered stud wall attributable to pit thickness and more decoupling. 

The double-wall has the disadvantage of taking an excessive amount of space which is an issue. It is one reason individuals go for staggered stud walls.

  1. “A commonplace double stud will take up around 2 feet”

    My math tells me that it only requires at most 12″. Each of the double stud walls are constructed with 2x4s and there should be approximately a 1″ gap between them. Install 2 layers of 5/8″ drywall plus green glue to the room facing sides of each of the two walls. Do not install any layers of drywall to the inside faces of the double stud walls. Since 2x4s are really 3.5 inches then you are looking at the following total wall width:

    5/8″ drywall + 5/8″ drywall + 3.5″ stud + 1″ air gap + 3.5″ stud + 5/8″ drywall + 5/8″ drywall = 10.5 inches

    Regarding staggered stud…

    “With staggered stud wall development, the space is somewhere around 10 inches to 12 inches”

    5/8″ drywall + 5/8″ drywall + 5.5″ (2×6 framing for staggering 2x4s) + 5/8″ drywall + 5/8″ drywall = 8″

    So the width difference between installing double stud vs. staggered stud can be as little as 2.5″, depending on the size of the double stud air gap.
