Quiet rock vs. Double Drywall: Which is Better?

When soundproofing walls, there’s one thing that you need to ask yourself. Which material is the best to use? Some people prefer quiet rock, while others consider double drywall. Although both have advantages, they also have disadvantages. Therefore, you need to weigh down which one will give more benefits: quiet rock vs. double drywall.

Quiet Rock

Quiet rock refers to a high-performance sound insulation material. You can use it for both interior and exterior walls since this material is lightweight, strong, and acoustically transparent. Not only that, but the quiet rock can reduce sound levels in homes and buildings, providing acoustic privacy between rooms in buildings.

Some of you might ask, how does quiet rock work? This material is a lightweight, high-performance acoustic panel. It is wood-based fibers that can be used to create an airtight, acoustically transparent fabric. The fiber’s density enables it to absorb sound while still allowing light and thermal flow through it.


Drywall refers to the building material which is used to create interior walls in homes and office buildings. It comprises two sheets of lightweight gypsum board. These are sandwiched together with a layer of mesh material in between the two sheets. 

Take note that the design of drywall panels is essential for soundproofing purposes. You can find drywall in many different thicknesses, ranging from ¼” thick to 11⁄2″ wide.

Quiet Rock vs. Double Drywall

Since quiet rock and drywall have different properties, some of you could be wondering which is better to use. Here are some things about them which can help you decide which is more ideal to use in your home:

  • Use quiet rock to protect any openings in your house from the sound. For example, you may use it around doorways to prevent sound from coming into the house.
  • Double drywall is highly recommended for interior soundproofing because its thickness can reduce the amount of noise that can pass through the walls in your home.
  • Quietrock can provide better sound attenuation. Meaning, it can reduce the need for additional layers, resilient or hat channels, and viscoelastic material. 
  • Quieteock on ceilings can block airborne sound. However, it doesn’t handle impact noise isolation which is quite similar to other drywall material.
  • Quietrock can be attached directly over the existing drywall, but it should be screwed through the current gypsum layer and into the joists. Note that this material is not recommended for 510 product use on ceilings because it may sag.

Quiet rock and drywall can both reduce the sound, which helps in making the environment more peaceful. But since they have different properties, each of them has advantages and disadvantages. It is up to you which one to use. To ensure that the material you will pick is suitable for your home, consider the pros and cons of each material.
