Soundproof Underlay for Wooden Flooring and Engineered Wood


Wooden flooring is a popular choice for the home as it can be very stylish and add value. There are so many different types of wooden flooring you can choose, all of which need different types of underlay.

For engineered wooden flooring, we recommend the Super Gold. This will provide excellent impact noise reduction and engineered wooden flooring is heavy enough to keep the underlay in place.

What is Soundproofing? – What to Consider When Blocking Noise


Sound is made up of vibrations that travel through the air in wave-like motions. They can travel through liquids, solids or gases and interact with our ear drums which is then interpreted by our brains.

In simple terms, soundproofing is any way of reducing sound travel from one place to another. There are lots of different ways to soundproof, all with different levels of effectiveness.

The features of the room and the type of sound are two major factors to consider when doing this, however you should also take into account:

  1. Distance – How far away you are from the noise.
  2. Materials – What materials are in the house which the noise will be travelling through.
  3. Loudness – You want to consider how loud the noise is. This is because you don’t want to overcompensate and put in place far too much soundproofing than you actually need, as this is a waste of money and can damage the quality of sounds.

For a more in depth explanation of the different approaches to soundproofing, read this post from 

How Can Underlay Reduce Sound and Loud Noises?

There are lots of different materials that can be used for sound reduction, all with their own list of benefits. Some materials that are effective include:

  • Acoustic Panels
  • Wooden Panels
  • Anti-Vibration Pads
  • Vibration Isolators

These are some good options for walls or furniture, but not for your flooring. If you put them under your floor they might achieve some soundproofing but would definitely not protect your floor or carpet. This is why underlay is needed.

There are two unique materials which are fantastic for your floor; foam and sponge. These materials will protect your carpet and do a great job at sound reduction. This is because they are porous materials, meaning they have tiny little holes in.

Tech Walla tells us that porous materials allow sound to pass through, converting it into a much smaller amount of friction energy. Sound is made up of vibrations and less friction energy means less vibrations, resulting in a much quieter sound.

However, not all foam and sponge products will be efficient at soundproofing. This is because they can have different cell structures, so it is best to opt for products that are made specifically for this task.

 Airbourne Sound and Impact Noise

What is Airbourne Soundproofing?


It is important to know that there are two types of sound reduction. The first is air borne noise reduction. This is the reduction of noises such as:

  1. Speech – talking, shouting, baby crying.
  2. Devices – Television, radio, computers.
  3. Animals – dogs barking, cats purring, birds squawking in the early hours of the morning.
  4. Transport – cars, buses, trains.

You will find in the underlay market that lots of companies claim their underlay products will completely block out air borne sounds. Unfortunately, this is not entirely accurate.

Underlay is not technically designed to block out air borne sounds. This is because if underlay was 100% air borne soundproof, it would be a completely solid material that has no comfort and wouldn’t protect your carpet.

At Underlay4U we have realised this through our extensive research. A small amount of sound reduction must be compromised to ensure maximum comfort and carpet protection, which is what underlay is intended for.

What is Impact Noise Reduction?


Impact noise reduction is exactly what underlay is designed for. This is generally the sound of footsteps, which can include:

  • Running
  • Walking
  • Jumping
  • Dropping objects


This is much easier to block out whilst keeping the comfort. The foam and sponge material are excellent at blocking out this kind of noise, which is why we use it in our underlay.

The higher the figure is for the impact noise reduction is best to purchase for impact noise reduction.

If you are wanting to stop noise from upstairs then an option is to block up any joists with Rock Wool and ensure any gaps that the noise can travel through has a deterrent then choose a high noise reduction underlay such as the Carpenter DeepStep 11mm or the Colours Red 11.4mm.

Where will I need Sound Reduction Underlay? – Which Rooms You Should Soundproof

Before you purchase underlay, it is really important to determine which room you are buying it for, especially when it comes to soundproofing. Although you should have underlay in every room in your house, you do not need soundproof underlay in every room.

It is usually unnecessary to fit it in any rooms on the ground floor. Unless you have rooms below the ground floor, we wouldn’t recommend soundproofing because there is nowhere for the sound to travel to underneath.

When it comes to the first floor of your home, it is still not necessary to soundproof every single room and it is down to the individual and their circumstances.

Soundproof Underlay for your Bathroom

When it comes to the bathroom, it really is down to personal preference. If hearing noise from other parts of the house in your bathroom bothers you, you may want to invest in soundproofing underlay.

However, it does not bother most people as you may be in the shower or have the radio on in the bathroom which will do a great job of blocking out noise.


Soundproof Underlay for your Bedroom

This is usually the most popular room of the house to soundproof. For many, the bedroom is their quiet place and a room of relaxation. If you have a floor above your bedroom or below it, it is a good idea to invest in soundproofing underlay.

There is nothing worse than trying to get to sleep at night and hearing constant footsteps and other people in your house still awake and moving around. Soundproof underlay will do a great job at reducing this noise and help you get a better night’s sleep.


Soundproof Underlay for the Office

Whatever kind of office you have, whether it’s at home, shared or in a city, it is usually a place of concentration. Other people walking around in your office above you can be an irritating distraction. Putting headphones in and listening to music could block some of this noise out, but music can also be a distraction from work.

Soundproof underlay is great for offices to block out foot traffic. Make your workspace a place of concentration and get rid of unnecessary distractions.
