Soundproofing a Loft Bedroom

In this blog, I will go through all the relevant details and processes through which you will be able to soundproof a loft bedroom effectively. Our guide will make you enable to decide easily a budget-friendly solution.

A loft bedroom is a terrific way to increase your living space, but it might be noisy down below. I decided to explore how to soundproof a loft bedroom when I transformed my loft. Here is a quick response:

The best technique for soundproofing a loft bedroom, unlike other rooms, is to concentrate on the floor. Impact noise transmission through the floor can be greatly reduced by using a lot of insulation and materials like mass loaded vinyl.

In this article, I’ll go through the many sorts of noise you’ll encounter when soundproofing a loft bedroom, as well as the best strategies to deal with them.

How to Soundproof a Loft Bedroom?

Before answering the question of soundproofing a loft bedroom we need to categorically explain the noise issues we generally face inside a loft bedroom.

Most Common Noise Problems in A Loft Bedroom

In a normal room, soundproofing materials are applied to the walls first, with the floor receiving less attention.

However, in a loft bedroom, soundproofing the floor is more vital. After all, the bedroom’s walls are the roof of the building, therefore there won’t be any sound transmission through them.

However, exterior noises such as birds and traffic must be blocked off, so don’t overlook the walls!

There are two different forms of sound waves. These are the following:

  • Impact Noise
  • Airborne Noise

Voices, TV, and music are examples of airborne noises. When sound waves collide with a solid surface, they move through the air and pass through it.

Impact noises, on the other hand, are generated when an object collides with a surface. Footsteps on the floor above and furniture being moved are two examples.

Vibrations flow through the object and generate sound waves when they reach the opposite side, causing impact noises.

Impact noises from the bedroom will be a significant issue in a loft bedroom, but airborne noises from outside and below will be a minor issue.

When it comes to soundproofing a loft bedroom, incorporating these materials during the construction stage will be considerably easier.

How to Soundproof A Loft Bedroom?

It’s important to focus on all locations available while soundproofing a loft bedroom to enhance the efficacy.

However, there is a clear hierarchy of importance for where you should begin. It goes like this, in my opinion:

  • Soundproofing Floor
  • Soundproofing Walls
  • Soundproofing Ceiling 
  • Soundproofing Windows 
  • Soundproofing Doors

Soundproofing Floor

You have a few alternatives when it comes to soundproofing the floor in a loft bedroom. These are the following:

  • Installing a floating floor 
  • Adding insulation 
  • Increasing mass

Installing a Floating Floor

This is the most time-consuming approach, but it will effectively eliminate any impact sounds. It works in the same way as disconnecting a wall does, however it’s done horizontally rather than vertically.

Sound waves cannot pass through a decoupled wall since both sides are supported on separate joists.

Building a suspended floor is similar in that the upper floor beams are laid on separate joists from the ceiling below.

In this procedure, you’ll lay the resilient channels along the existing ceiling joists and then attach the sound clips in the same way you’d decouple a wall.

Then, on top of that, you’ll need to place sheets of MDF, which will serve as the foundation for your bedroom’s floor. Acoustic caulk should be used to fill any gaps between the MDF sheets.

You can also lay a new set of floor joists completely apart from the existing ones. I’d suggest either stacking bricks or making holes in the walls to raise them.

The disadvantage of this choice is that it raises the floor significantly, which isn’t always a good thing in a loft bedroom. Because vertical space is frequently limited in this area, the resilient channel technique is probably preferable.

You’ll also need to insulate the cavity, which I’ll go over in more detail below.

Adding Insulation

When it comes to soundproofing, the floor hollow might be a major problem. Sound waves can reflect off the surfaces and reverberate in the empty area, which works like an echo chamber. This can make them appear to be louder than they are.

It is therefore critical to fill this hole with the proper material to reduce sound transmission.

This task is ideal for mineral wool insulation. It has an open construction that allows sound waves to pass through it. They become caught inside and have to exert all of their energy to move the threads. Sound waves are converted into thermal energy in this way.

Acoustic mineral wool is more effective at suppressing noise transmission than ordinary cavity insulation because it has a higher density.

Make sure it’s not packed too tightly in the floor hollow while placing it down. It works best when the sound waves are not compressed, as this permits them to get trapped inside.

Mineral wool is also an excellent thermal insulator, so this is a win-win situation.

Adding Mass

Finally, increasing the floor’s mass will help to limit noise transmission. Vibrations are the source of impact noises, hence making a structure heavier makes it more difficult to vibrate.

There are a few goods that would be great in this situation:

Apply one of these products to the floor’s surface, either under or over it. It doesn’t matter where you put them in the floor sandwich as long as you cover them with more appealing flooring.

Here are some more suggestions for improving the soundproofing of your floor:

  • Impact noise is effectively muffled by thick carpet. • A high-quality carpet underlay will provide another layer of sound dampening to the structure, so avoid hardwood flooring if at all possible.
  • MDF is a good choice for a building material because it is far less rigid than plywood or wood.
  • EVA foam gym tiles are a good option if you need an extra layer of dampening material. They can also be readily buried under the carpet.
  • Rugs may not make a significant impact, but they can help if you’re still having issues.

Soundproofing Walls

As I previously stated, walls aren’t a significant issue in loft conversions. While you’ll still hear road-noise, it won’t be as awful as it would be on the street.

When you’re on the 3rd or 4th floor of a building, airborne noises are generally less strong.

As a result, soundproofing the walls of a loft bedroom won’t require as much effort.

We would advise the following solutions:

  • Insulate Walls
  • Decouple Walls
  • Add Mass

Pipes run through the lofts of many older buildings, or in the ceiling cavity above the top level. This is usually due to the installation of hot water tanks in lofts.

Depending on the configuration of your building, you may also have HVAC pipes or other plumbing work running throughout the loft.

Keep an eye out for pipes if you’re putting up new walls in your loft bedroom. Because noise travels well via pipes, this can be a significant source of unwanted noise.

Fibreglass pipe wrap is the most effective way to insulate them. Polystyrene or rubber pipe insulation should be avoided. While these are wonderful for thermal insulation, they aren’t very good for sound insulation.

Soundproofing Ceiling

Soundproofing the ceiling works similarly to soundproofing the floors and walls. In reality, the walls and ceiling in many loft bedrooms may be the same thing.

If you can, decouple, but if that’s not possible, focus on adding as much mass and insulation as possible. This effectively prevents sound from leaking in from the outside.

Make a point of focusing on minor gaps and filling them with something like Green Glue.

Soundproofing Windows

Because most lofts were built without windows, you’ll often find very recent windows in a loft conversion. This is a fantastic place to start when it comes to soundproofing because it almost always indicates they’re double-glazed.

Consider triple glazing if you have the financial means to do so. Although it isn’t a major improvement over double glazing, it does add another layer of glass, and therefore another air cavity, which helps to lessen noise transmission.

Weatherstripping should also be used to seal the margins of the windows where they meet the frame.

Although weatherstripping is primarily used for thermal insulation, heat and sound can also pass through minor holes. It will make a difference if you close any little gaps.

You should also use acoustic caulk to seal around the glass. Acoustic caulk, unlike regular caulk, is more elastic and will stretch if the structure shifts.

Material Needed
Weather Stripping

Soundproof Door

Doors, like windows, are a common source of soundproofing problems. The advantage of a loft bedroom is that the doors are usually at the bottom of the second-story stairwell.

Above all, this means that any sound that passes through them won’t be a major issue in the bedroom.

Even yet, there are a few things you can do to make them more soundproof.

Finally, make sure all gaps around the door and its frame are sealed. Use a door sweep to seal any gaps at the bottom of the door, and weather stripping around the frame.

Acoustic caulk, like window caulk, is useful for any small gaps around the doorframe. You might also replace the door with a solid soundproof door, though these can be quite costly.


The method of soundproofing a loft bedroom isn’t particularly complicated. You should be able to accomplish a decent job if you have some DIY experience.

My best recommendation is to concentrate on the floor, as that will be the most difficult to deal with. You might not need to proceed any farther if you can properly stop the sound transfer from below through the floor.

Frequently Asked Questions (FAQs)

How to soundproof a loft bedroom?

We have discussed all the procedures and possible solutions to soundproof a loft bedroom in this blog here is the summary:

Here is a quick response: The best technique for soundproofing a loft bedroom, unlike other rooms, is to concentrate on the floor. Impact noise transmission through the floor can be greatly reduced by using a lot of insulation and materials like mass loaded vinyl.

How do I reduce the noise in my loft room?

Here are the things to follow:

  • Increase the floor’s bulk.
  • Enhance the floor’s ability to absorb sound energy and vibration.
  • To prevent sound from reverberating and amplifying in this sealed chamber, use acoustic insulation between the timber joists.
  • Make use of a variety of high-mass materials.

How do you soundproof a loft open?

With exposed rafters, loft ceilings are sometimes left unfinished. If this is the case, fill the ceiling area with a blanket or spray foam insulation for rapid soundproofing. To boost the level of sound suppression, cover the ceiling with drywall or another material.

Are lofts more soundproof?

A condo or an apartment is neither more nor less soundproof than each other. As a result, you can’t pick one over the other based on noise levels.

Can you soundproof a roof?

Soundproofing panels are used to reduce noise. Adding soundproofing ceiling panels is an excellent alternative to installing acoustic insulation slabs in the ceiling to reduce sound transfer. You can make it more difficult for sound to move through the structure with clarity by adding mass to the ceiling.

Does attic insulation reduce noise?

One of the major advantages of attic insulation is lower energy expenses. Soundproofing and noise reduction, on the other hand, are significant advantages. By restricting sound transmission, attic insulation acts as a noise barrier.
