Quietrock Vs Double Drywall: A Detailed Comparison

Here is a detailed guide between Quietrock vs double drywall and how effective each material is in soundproofing.

I have always recommended drywall in most previous projects, such as an excellent soundproofing material when soundproofing bass noise coming through a wall.

While double layer drywall is highly effective in dealing with airborne and impact noises, how does it compare with Quietrock?

Let’s dig deeper.

Quietrock Vs Double Drywall Detailed Comparison

Quietrock is sound-reducing drywall manufactured by PABCO Gypsum.

In other words, Quietrock is a brand that produces a wide range of sound-reducing materials.

Among these materials is Quietrock Drywall that offers state-of-the-art acoustic performance without eating up the valuable floor space.

The main difference between Quietrock and double drywall is that- Quietrock drywall is developed with patented thin-wall technology.

This helps improve sound transmission class performance at the same time without using too much materials.

In simple terms, you end up saving your valuable floor or wall space.

Quietrock easily outperforms double gypsum drywall.

It also often exceeds the sound transmission class for most wall applications and is also more reliable than resilient channels.

Why Quietrock Is Better Than Double Drywall?

As we’ve already seen so far, Quietrock and double drywall are equally the same materials, with Quietrock taking on some advantages.

Let’s see why you’d be better off choosing Quietrock drywall over the traditional gypsum drywall.

Easy Installation

When using regular drywall materials, double drywall, you will need to add other products such as Green Glue Sealant in this case.

This can be quite tricky and, at times, require experts or someone with technical experience.

On the other hand, Quietrock soundproofing panels are quite simple to install.

In most cases, they don’t require additional products to improve their soundproofing performance as they are already designed with acoustical insulation in mind.

Space Saver

Using regular double drywall not only translates into thicker walls but also results in space reduction.

However, since Quietrock drywalls use thin-wall technology, you never have to worry about space.

The sheets are thinner compared to traditional drywall sheets.

Better Sound Transmission Class (STC) Value

Drywalls are rated according to the sound transmission class (STC).

The higher the value, the better the product is in terms of soundproofing.

According to the Quietrock manufacturer, a single layer of Quietrock drywall sheet gives the same soundproofing properties as 8 layers of regular drywall materials.

Quietrock Can Be Used Alongside Regular Drywall

If you already have regular drywall materials installed in your room, then you’ll be glad to know that you don’t have to remove them to install Quietrock sheets.

You can simply install Quietrock over them to improve the room’s acoustic properties.

Quietrock vs. Green Glue

Before we get to look at Quietrock versus green glue, let’s look at some of the disadvantages of using Quietrock.

  • Not for Ceilings: You can never use Quietrock sheets to soundproof the ceiling. Luckily, you can use regular drywall panels to soundproof your ceiling.
  • Quietrock sheets are costly. One sheet will cost you about 7 times the price of regular drywall sheets.

Quietrock brand has come up with an acoustical sealant that works as same as Green Glue Sealant.

The QuietSeal Pro is a perfect and one of my most recommended Green Glue Alternative Products on the market today.

In my experience, both products are pretty effective when it comes to soundproofing against impact sounds.

Additionally, they never dry up, therefore, providing all year through soundproofing.

While QuietSeal is quite affordable, on the other hand, Green Glue is more versatile, provides greater coverage, and can be used on ceilings.

Final thoughts on Quietrock vs Double Drywall

Quietrock and double drywall are designed for soundproofing purposes.

Luckily, Quietrock takes the lead as an effective sound dampening material even though it’s quite expensive and not ideal for ceilings.

These materials require some slight structural modification to your apartment/home, and I would not recommend them to anyone living in a rented unit.

If you live in a rental unit where the landlord doesn’t allow any structural changes to the house, I recommend you try soundproofing using acoustic foam panels.
