In this blog, I’ll go through attic insulation with soundproofing in great depth. Insulation is frequently inefficient at dampening noise. Rather than insulating a loft, this blog concentrates on soundproofing one.
Celotex or an equivalent will be found in most lofts and attics as a component of the loft insulation. Insulation is frequently used to refer to thermal insulation, which keeps attics and loft areas warm in the winter and cool in the summer.
When investigating strategies to block the flow of sound, the terms acoustic insulation and soundproofing are frequently employed. Blocking both acoustic and vibrational impact disturbances is the best technique to soundproof an attic floor.
While acoustic sounds such as speaking, music, and echoes can be quickly blocked by inserting dense materials including mineral wool among joists, impact noises such as footsteps, bass tones, and dropping stuff will necessitate the installation of an impact absorption barrier between the sound as well as the bottom half of the floor.
How to install attic insulation with soundproofing?
Here are some methods for installing attic insulation with soundproofing to make your attic quieter while filtering out undesired noises. I’ll show you how to soundproof your attic floor effectively and efficiently so that no one on the lower levels of your home is bothered by loud footfall and other noises that carry.
- Use Floor Floaters beneath the Joists
- Fill the Space Between the Floor Joists with Insulation
- Use Soundproofing Tape
- Use Green Glue compound
- Add underlayment to the floor
- Add sound-absorbing flooring materials
- Soundproof the Ceiling below the Attic Floor
Use Floor Floaters beneath the Joists
Attic floor floaters are indeed an effective solution to reduce noise in the attic. This is because hard rubber is used to make these joist isolators. It will give extra support and limit vibration or undesired movement on your joists after it is installed between them.
Floor floaters will efficiently deal with those bothersome vibrations, harsh bass, or rhythms that can cause you to lose your mind.
When it comes to impact noise, floor floaters are one of the greatest options. They’re shockingly simple to set up. You may do it in a few hours on your own. Just make sure they’re positioned properly beneath each joist. You’ll generally get the best results if you keep the spacing between each floater around 16 and 24 inches. These are quite valuable things when you think about the amount you get and the pricing. Overall, for your attic floor, it’s an efficient construction choice.
Fill the Space Between the Floor Joists with Insulation
Understand that impact sound is the vibrational transfer of noises. Open space can also allow sound to travel across rooms. This is known as spatial sound, and it involves sound waves entering and reverberating in spaces. Consider how a guitar’s hollow body makes the chords sound louder than they are. Sounds from the attic will be amplified by the gaps among your attic floor joists.
Noise Insulation mats should be used to fill in the gaps between the joists. Rather than allowing sound to bounce around in these gaps, the insulation will collect and attenuate it, ensuring that it remains in the attic.
To experience the advantages of owning a less resonant attic floor, cut your insulation pieces to length and fit them in the spaces.
Mineral wool batts are also available. It will demonstrate exceptional ability to deal both with airborne and impact noise. You may easily muffle even the loudest noises with 2 inches of genuine soundproofing material.
- Fill the gaps between the joists with these batts, which you may cut to size with a knife and insert in between until there’s no more space.
- The more surface area you cover, the greater soundproofing you will achieve.

As you’ll see, this is a very low-cost answer to your issues. The size of your floor has a role.
Use Soundproofing Tape
Soundproofing tape should be applied to the tops of the joists before laying the subfloor. This is a very cost-effective method of noise reduction.
It will effectively muffle the noise created by stepping between the subfloor and the joists. Yes, you could be the main source of the noise at times.
It can be uncomfortable for your ears to walk on the floor when there is a gap between them and the subfloor. Nevertheless, here is the solution, and once you’ve completed it, you won’t have any more issues.
Use Green Glue compound
The best impact noise blocker is green glue. Reverberations and bass will be reduced by half. If you are using green glue on the subfloor, for instance, the vibrations will be reduced. Nails are commonly used to attach flooring panels in most building projects.
Although this method works, nails can loosen with time. As people walk on the wood, it squeaks and flexes, which anyone underneath may hear. With the help of Green Glue Noise-Reducing Compound, you can solve this problem.
Before laying down the flooring panels, apply Green Glue to the tops of your attic floor joists. The panels can be nailed as usual, but the Green Glue will produce a tight seal to prevent the panels from shifting or flexing while people move about. Green Glue can also aid with soundproofing by absorbing some of the vibrations that occur between the flooring panels as well as the joists.
Use an underlayment to the floor
Add a soundproofing floor underlayment to your attic floor to improve its sound-absorbing properties. They’re ideal for suppressing sound transmission and vibrations up from the ground. They can be used beneath any type of flooring, including tile, laminate, carpet, hardwood, and stone.
There are numerous materials to choose from when selecting a robust underlay, including fibre, rubber, foam, and cork.
A shredded rubber mat is one of the greatest options for sound absorption. Because it is thicker than cork or foam, it has better soundproofing properties.
You may usually apply the damping material immediately to the current subfloor layer if your subfloor isn’t too thick and is composed of a material that can be screwed into. Because the damping compound must exist among two hard floors to function properly, it must have a strong layer above it.
A cement board is a viable option. Choose a thicker sheet of oriented strand board or moderate fiberboard if the thickness isn’t an issue and you need even more sound insulation. When it’s time to put your wooden flooring down on top of the underlay, do so in a floating raft. This implies that no screws, nails, or adhesive will be used to secure the wooden flooring to the layer beneath them.

Add sound-absorbing flooring materials
After you’ve soundproofed your attic floor and done everything you can, there’s only one thing left to do to eliminate any noise.
You must avoid echo noise from yourself as well as footsteps sounds. Simply get a soft rug, such as this one, or interlocking floor tiles.
Both are excellent echo deadeners, or which you choose is solely a matter of personal preference.
Many people are familiar with soft carpets, but few are familiar with interlocking floor tiles.
These tiles are thick wood mats with a high density, that will not only block noise but also keep the temperature a little higher than it otherwise would be.
Installing them is a breeze because they are similar to puzzles. The most basic puzzles I’ve ever seen.
You should try to cover as much ground as possible. The more ground you traverse, the less echoing and footstep noise you’ll hear. Nonetheless, they are excellent thermal isolators that will save a significant amount of energy.

These are the soundproofing options for your attic floor. You may not like some of them because they are somewhat extreme, but if you want to see results, you will have to put in some work. These are, however, some techniques that you can learn now and apply later when building your attic floor.
The majority of the options are noise reduction measures.
As a result, once you’ve completed the structure correctly, you won’t have to worry about the noise.
This blog should have given you some insight into how soundproofing attic floors operate.
Frequently Asked Questions (FAQs): Attic insulation with soundproofing.
Is soundproofing possible with attic insulation?
Yes, insulation reduces noise from the outside as well as inside your home between different levels and rooms. If outside noises are greater than they should be, it could indicate a lack of insulation. The greatest types of insulation for sound suppression are loose-fill cellulose and fibreglass insulation.
What is the finest soundproofing ceiling insulation?
Because of its mass, drywall is the finest soundproofing material for a ceiling. Insulation, green glue, and noise proofing clips, in addition to drywall, are good soundproofing materials.
How effective is soundproofing insulation?
Some people believe that adding insulation to their home will soundproof it, but the truth is that insulation and soundproofing materials are not designed to work together. Although foam insulation can reduce sound transmission by up to 80%, some sounds will still be transmitted.
Is it true that lofts are soundproof?
One of the draws of a loft is the open space. Open spaces, on the other hand, are notoriously difficult to soundproof. While you won’t be able to transform your loft into a perfect acoustic bubble, you can muffle it with a little creativity.
When it comes to insulation, what’s the difference between thermal and acoustic?
Thermal insulation prevents heat transfer, while acoustic insulation prevents sound transmission or reverberation. The resulting product is thermal acoustic insulation, which reduces both heat and noise transfer.
Is Rockwool a better sound absorber than fibreglass?
When compared to similar products, Roxul and fibreglass have similar acoustic qualities.
Rockwool is less difficult to deal with than fibreglass, and it is better for acoustic panels. It also absorbs lower-frequency sounds better than equivalent fibreglass.
