In this blog, I discuss the best methods for soundproofing a Hollow Door, as well as other possibilities. Soundproofing Hollow Doors in your home can assist create a quieter, comfortable environment.
Your home should provide you with a level of comfort that you won’t find anywhere else. Nothing should stand in the way of your personal space in your own home. When it comes to noises, the entrance is the most notorious element of your house. It has a lot of air spaces in it. The noise emanating from your door may be hollow. Nowadays, most homes have hollow internal doors, which are great for saving money but terrible for soundproofing. I’m always looking for solutions to soundproof a Hollow Door because it’s usually the weakest portion of a room.
The majority of Hollow Doors are composed of MDF or cardboard. Between these two materials, there is a space. They allow for greater noise to cause disruption in the home than any other material. It takes a lot of effort to soundproof a Hollow Door, but it is better to improve its noise-blocking capability.
How to soundproof a Hollow Door?
Soundproofing the Hollow Door can be done in a variety of ways. The following are simple techniques to soundproof the Hollow Door.
- Add mass to the Hollow Door
- Seal the cracks in the door
- Soundproof the Door Frame
- Install a Draft Stopper underneath the Door
- Use soundproof curtains
- Dampen the noises
Add mass to the Hollow Door
First and foremost, you want to give the door as much weight as feasible. The only mass can efficiently block sound waves.
Attaching large and bulky objects to a door, on the other hand, can make it harder to open and close it.
You have a few alternatives for adding mass to your door.
Sound deadening foam
Sound deadening foam, such as Dynamat or Hushmat for automobile interiors, is the greatest thing to consider when soundproofing Hollow Doors. This is a simple installation that is usually less than an inch thick, allowing your door to open and close normally.
If you go with one of these options, I propose adhering it to a sheet of wood or drywall, which you can then screw to your door. This is due to the sound deadening mats’ self-adhesive backing, which is simple to apply but difficult to remove. Furthermore, it will very certainly leave some glue on the door.
Acoustic Foam Panels
Acoustic foam panels are foam sheets that can be used for a variety of soundproofing projects. Acoustic foam panels are sound-absorbing instead of soundproofing options. They reduce reverberation by gathering sound waves that bounce off hard objects such as wood. Furthermore, these panels keep the room’s interior sounds from escaping.
These panels can be installed on the door’s surface or, if you’re handy and want more involved DIY projects, the foam material can be installed inside the door for sound absorption. To do so, you’d detach the Hollow Door from its hinges, disassemble it, and put the foam material inside.
MLV (Mass Loaded Vinyl)
This is a limp mass, which means sound waves just evaporate against their surface. It’s not too pricey, and it’s also not too thick. However, depending on how solid your hinges are, it may be too hefty to put on a door.
Mass loaded vinyl soundproofing barriers are constructed of salts, sands, and microscopic metal particles, and are a greener alternative to traditional soundproofing materials. MLV barriers are typically installed in drywall and plywood assemblies.
In general, you can use a peel-and-place application or a soundproofing adhesive to increase mass to your door.
Seal the cracks in the door
When doors are in the frame, they have a tiny space surrounding them by their sheer nature. This required gap, meanwhile, is great for allowing in noise, thus finding measures to close it as much as possible can make a significant impact on noise pollution.
Consider using a soundproof door strip, such as a fire-resistant door gasket. Because many of the same principles apply to soundproofing, many insulation and fire-control solutions work well. When the door is closed, these door gaskets will aid to create an airtight seal.
Weather-stripping, which simply goes around the edge of the door to close the gap, is another option. Weather-stripping is much less invasive than a door gasket, and it leaves no trace, making it ideal for soundproofing an apartment door.
Soundproof the Door Frame
Examine your doorframe in great detail. A slight gap may be seen around the perimeter. Excess noise transfer is easily caused by sound waves travelling through this air-filled space, however, there are solutions. There are only a few things you can do to make it more soundproof except replace the door frame with solid metal. I’d start by adding as much mass as possible, such as tearing up some sound deadening rugs and glueing them to the door frame.
This, however, will be limited because it may prevent the door from opening. Another option is to use acoustic caulk, such as Green Glue, to fill any cracks or gaps in the door frame. Acoustic caulk, unlike conventional sealant, is silicone-based, which means it won’t crack if the home moves.
Install a Draft Stopper underneath the Door
Move on to the bottom of the door now that you’ve taken care of the gaps in and around the door frame.
The soundproofing of any room is compromised by the distance between the door and the floor.
Get yourself a door sweep or a door draught stopper to solve the problem. It will not only help to close the bottom gap and prevent undesirable outside noise, but it will also help to increase the room’s thermal insulation.
Furthermore, a door sweep will keep bugs and other small animals out. There are numerous options available that come with a self-adhesive strip which are very easy to install if you don’t want to drill holes in the door to screw the door sweep in.
Use soundproof curtains
It’s simple to install a curtains rail above your door, and it’ll allow you to hang acoustic curtains in front of it. When you close the door, pull these shut to reduce the amount of noise that comes through.
You might also use heavier draperies, such as velvet, as an option. Because curtains are frequently composed of dense material that lessens sound waves, they do a fantastic job of soundproofing. Acoustic curtains across a door will also assist keep heat in, which can be a plus and a minus.

Consider using a soundproof blanket
Soundproofing blankets are very effective. They are dense and sound and air cannot pass through them. You can set them up on your own. So, when it comes to soundproofing blankets, you don’t have to be concerned.
The blankets should be pinned to the doors. This should be done from the interior of the bathroom. Alternatively, you can drape the blankets like curtains. To attach the blankets to the door, you can use glue or nails.
Acoustic blankets with grommets are also available. These blankets can be hung on the front door. Use curtain rods or rails to hang them. Attach the conventional curtains in the same manner. Invest in the thick blankets for maximum effectiveness. If you hang your blankets over the door, though, vacuum them regularly. Dust is easily absorbed by blankets. If you prefer to hang them as curtains, keep in mind that they will need to be washed occasionally.
If you put blankets on both sides of the Hollow Door, this solution will be considerably more effective in soundproofing it.
Dampen the noises
Instead of soundproofing a Hollow Door, regulate noises closer to their sources, which should limit the quantity of noise pollution that reaches the entrance. However, I’d at least attempt this approach in conjunction with some form of soundproofing for the door.
Consider putting rugs on the ground to help soundproof a door to a corridor, as this will assist reduce echo and vibration. To lessen echo even further, hang paintings or frames on the walls.
Consider placing heavy furniture, like bookcases, near the door within the room. While this won’t enhance soundproofing, it will assist with things like echo, and the dense books will absorb sound waves as well.
I’ve found that using any thin but dense mass, such as sound-deadening car mats or mass laden vinyl, is the best approach to soundproof a hollow door. These choices, however, can be more costly and need some DIY skills to complete.
Fortunately, soundproofing a hollow door with common home goods is possible. If you choose one of them, keep in mind that it will not be as effective as a soundproofing product. It’ll be impossible to soundproof a hollow door in either case, but there are techniques you can do to make a significant difference.
Frequently Asked Questions (FAQs): How to soundproof a Hollow Door?
What Is Inside a Hollow-Core Door?
Assume you split a hollow-core door in two vertically. Two layers of veneer or outside panelling and an inside honeycomb-patterned cardboard layer are visible on the inside. A wooden frame connects these three levels.
Hollow-core doors are less expensive and easier to install because of the honeycomb-patterned cardboard layers. However, because it is air-filled, it is more susceptible to noise transfer than solid-core or wooden doors.
What Signs Do You Have That Your Door Is Hollow?
Knocking on your door is one technique to discover if it’s hollow. When you compare the sounds of banging on a solid-core and hollow-core door, you’ll notice that hollow-core doors are, as you might expect, hollow. However, not all hollow-core doors sound hollow. Look for additional telling signals, like whether your door is veneer or lightweight, in these situations.
Is It Possible to Fill a Hollow Door With Foam?
Filling a hollow door with foam is possible, but it takes practice and time. Spending in one or more of your other soundproofing alternatives is the best way to soundproof your hollow inside door.
What is the best way to reinforce a hollow door?
Add a high-security steel striker plate with four screws that go deep into the stud framing and longer screws to the hinges to strengthen the door. This style of reinforced door is practically impenetrable to kicks.
Is it true that solid doors are more soundproof?
Solid doors are more soundproof than hollow-core doors. The honeycomb-patterned cardboard inside fills a hollow-core door with air, making it easier for sound to pass through. Furthermore, the veneer or panelling outside layers are thinner than solid wood doors, allowing sound waves to flow through more easily.
Are Hollow-Core Doors Beneficial?
The fact that solid doors are more soundproof than hollow-core doors does not imply that one is superior to the other. Hollow-core doors offer their own set of advantages: they’re less expensive and easier to transport and install than solid doors. Fortunately, there are ways to improve hollow-core doors so that you can have the best of both worlds.
