What Exactly is Drywall?

What Is Drywall

Drywall is a building material used to cover interior walls and ceilings, and it’s the most common application in modern homes and buildings.

Traditionally, walls were covered with plaster that was made of various materials like sand, lime, and even animal hair, and applied in a smooth paste to make interior walls.

When gypsum was discovered for its quick-drying abilities, it was added to the plaster, and eventually became the norm.

A drywall sheet or panel today consists of plaster in the middle and with thick sheets of paper and facer on either side, with some variants being additives that make the water-resistant or made with a higher density to block sound.

Drywall is sold in panels or sheets and it varies in thickness and materials. These sheets can be applied by builders and home DIYers as they can be easily cut down to the size needed and then stuck wherever needed.

Even those without experience in building and construction will usually be able to hang drywall, and it can be a quick fix to a soundproofing problem that you’ve been waiting to solve.

How Is Soundproof Drywall Made?

How Is Soundproof Drywall Made

Drywall is the most common way to build an interior wall these days, and although this modern variant of timber and masonry is easier to install, cheaper, and lighter, it falls flat in the sound department.

However, manufacturers of drywall have heard the calls of builders and homeowners and developed panels that are better at keeping sound contained than others.

Soundproof drywall features different materials like polymer and noise control gypsum boards that are layered uniquely.

These sheets then dampen the sound waves that are sent through the walls and turn them into heat, as they cause vibrations and friction, and can then convert that friction into thermal energy.

To get this effect, a standard sheet of soundproofing drywall might feature a middle layer of polymer and then multiple layers of noise control gypsum on either side. These convert the sound waves into thermal energy, so whoever is on the other side gets a muffled version of the noise.

In some cases, it may be cheaper to install two or more layers of basic drywall with just as good of a result as the soundproofing type, but only if your sound requirements are moderate to minimal.

There are downsides to doing this though, like losing floor space, having to smooth out any bumps, added weight on the walls and ceilings, and more work, but this is only the case if you’re applying more than two layers.

The Correct Installation of Soundproof Drywall

Before you can go ahead and install your new layers of soundproof drywall in your home, you’ll first need to assess the area.

A few questions to ask would be: what type of drywall do you need, are you going to add any other layers of insulation or sound blocking, and how much of it is required to adequately do the job.

Once you have the sheets ready, soundproof drywall is just as easy to install as regular types. To start, you might want to add a layer of soundproofing insulation that can provide a further barrier against sound, as well as assist with insulation to keep temperatures regulated in your home.

Apply the drywall sheets one at a time but be sure to use the right screws to attach them to the studs. For metal studs, a fine threaded screw is best, and for wooden studs, a coarse threaded screw should be used.

If you have greater needs for soundproofing, you might use a special resilient channel that attaches to the studs of the wall, with the drywall then attaching to them.

Once everything has been screwed in, apply soundproof glue to seal up any cracks, seams, power outlets, and light switches, as sound can easily escape from areas like this. Cover with whatever finish you want, like plaster, and smooth it out before painting or covering as you choose.
