Soundproofing a Top Floor Flat

Soundproofing a top floor flat is not much different than any other house or flat. The biggest difference is that you may need to consider a few extra sounds usually coming from above. 

A top floor flat must consider the outdoor noises impacting the roof and transmitting into the room through the ceiling. That’s why besides all the usual things, you need to give a little extra attention to soundproofing the ceiling to prevent the sounds of the elements.

In a top-floor flat, you will hear everything from people strolling at the roof to falling objects. Not to forget, rain, snow, and hail will also make a lot of impact noises. Living at the top floor flat becomes a threatening experience particularly on stormy nights if your ceiling isn’t properly soundproofed. 

When you are trying to rest, getting work done, or when you just want to kick back and relax in your apartment, these noises can be a huge distraction.

If you want to cut out the blaring noises from your noisy neighbors below, or even if you’re the noisy one, there are ways you can dampen the sound that transmits through the floors.

Materials with good noise-reducing properties will be necessary for soundproofing a top floor flat to achieve optimal sound insulation. The quality of the soundproofing will also directly depend on the weight of the material used on the floor or under it.

Determining the Type of Noise 

It takes a simple test to determine the type of noise that passes through the floor of your apartment. Place your hand on the floor when you hear a sound; if you feel the floor vibrating, then it’s structure-borne noise, but if it doesn’t vibrate, then it’s airborne noise.

11 Ways to Soundproof a Top Floor Flat

You can easily soundproof a top-floor flat by one or more of the eleven techniques given below;

  • Insulate the Joists
  • Install Acoustic Insulation
  • Use Carpets & Rugs
  • Add Bookshelves
  • Install Soundproofing Floor Mats
  • Decorate the Walls
  • Seal the Cracks
  • Use Soundproof Windows
  • Add Extra Flooring
  • Add Deck Screws
  • Install Rubber Floor Mats

Insulate the Joists

This technique includes removing the roof, installing insulation, and fixing the ceiling between the joists. This is the second-best thing you can do, aside from installing false ceilings. It will give some degree of insulation, but will not effectively eliminate water pipe noise or footsteps.

The overall cost of insulating the joists is about £2,000 and this is for a ceiling of size 30’ x 30’. It is not an easy technique as you have to remove and replace the ceiling to do so. 

Install Acoustic Insulation

You can also use acoustic insulation panels to soundproof your top-floor flat ceiling. 

These can be purchased cheaply and are relatively simple to install. These panels simply function by placing them on your ceiling with the help of adhesive. In terms of soundproofing, they are perhaps the least effective, yet the cheapest.

Despite its low performance, it can still provide relatively better insulation than uninsulated ceilings. This is a good way to start your soundproofing and will let you know if you need to invest in more costly options such as insulating the joists and adding false ceilings.

Use Carpets & Rugs 

The addition of rugs or carpet to your floors will help prevent sounds from bouncing off the flooring. Rugs are also a perfect way to bind a room’s decor together, and your downstairs neighbor would certainly appreciate the muffled noises coming from your house.

Add Bookshelves

Bookshelves and their heavy, thick books provide outstanding sound insulation. They also give you extra storage space and are a cheap way to insulate your walls. 

Adding a bookshelf will help you dampen the sounds from the outside while also absorbing the internal sounds and reducing echo. 

Install Soundproofing Floor Mats

Soundproofing floor mats is one of the simplest ways to soundproof flooring and insulate the flat. These mats are often used as underlay and use the decoupling technique to dampen sounds.

You need to first measure the flooring size and buy mats that can adequately cover the flooring space. Available in different sizes, designs, and textures, they are similar to padded tiles.

They are often called interlocking mats as their edges are designed in such a way that they easily interlock with one another. This gives the flooring a sense of uniformity and consistency.

They are also highly durable, easy-to-clean, and can be installed on existing flooring with ease. 

Decorate the Walls

Wood and glass have an incredible ability to insulate the room and dampen sounds. They can absorb a lot of noises in a room as their soft surfaces cause minimal sound reverberation. 

Sound-absorbing materials such as cotton and foam are perfect for decorating the walls and insulating the room. If you desire more stylish alternatives, you can try using framed pictures, art pieces, wall decor, wallpapers, and wall tiles.

Hanging multi-layered and stylish curtains and blankets isn’t also a bad choice as they provide good insulation and are aesthetically pleasing. Nowadays, many sound deadening curtains are available in the market that enhances the aesthetics and deadens the sound. 

Seal the Cracks

Cracks, empty spaces, and holes may seem insignificant, yet plays a big part in insulating homes and blocking sounds. There are many spaces around the door and window frames from where sound waves can easily penetrate through. 

Using door guard, door sweep, and weatherstripping tape are some effective ways to seal the cracks and minimize sound transmission. In terms of a top-floor flat, you may also need to keep an eye on holes in the ceiling.

Some fixtures and lighting have spaces around them and these tiny spaces let in a lot of noise. So, it is best to keep an eye on these spaces and seal them appropriately. 

Use Soundproof Windows

Soundproof windows are designed to provide you better sound insulation by blocking out the outdoor noises and damping the echo from the inside ones. 

You can either opt for double or triple glazing windows to insulate your home and these window system often have multiple layers of glass pane separated by a gas-filled cavity. 

Add Extra Flooring 

Adding an extra layer of flooring can do you a world of good and soundproof your top-floor flat effectively. This will not only help you better absorb the home sounds and minimize echoing but will also transmit lesser noises to the floor below. 

Carpet, rugs, and other alternatives all fall under extra flooring options and help you perfectly soundproof the home on a minimal budget.

Add Deck Screws

Sometimes, the floor noise problem isn’t as big as it seems, and adding a few deck screws is all you need to resolve this issue. All you need is a drill, pencil, driver, and some deck screws. 

To add deck screws, you need to start with removing the existing hardwood flooring, linoleum, tile, or carpet. You have to remove the existing flooring to gain access to the subfloor. 

You don’t necessarily have to remove the entire flooring and revealing the squeaky flooring spaces is all you need to do. Afterward, identity the squeaky spaces, mark them with a pencil and drill pilot holes. 

Use the size of the screw to find the relative size of the drill bit and it is always best to choose one that’s just a little smaller than the screw.

Once you have drilled the holes, place a floorboard in the desired position per the drill holes. Insert the deck screw’s sharp tip into the drilled pilot hole. Using a bit driver, drive the screw through the board into the framing to hold it at its place.

These floorboards can help you fix the squeaky floors with relative ease and simplicity. Always apply a bit of pressure while fixing the floorboards to effectively remove any cavities in between. 

This will ultimately help you get a more soundproof and solid floor with no annoying squeaky sounds. 

Install Rubber Floor Mats

Rubber is the best soundproofing material and if a machine or appliance is the cause behind the noise problem, rubber floor mats can help you solve this with ease. 

These mats are perfect to dampen the vibrations and sounds of any machine or appliance from dishwasher and stereo system to refrigerators and dyers. 

The idea is to place these mats directly below the appliance to disconnect its connection with the hard flooring below it. Using the decoupling technique, mats dampen the sound and also minimizes flanking noises.
