Advice on ‘What’s the best underlay?’
Should I use the same underlay for the whole house?
We normally recommend using a different type in bedrooms and lounges to that used on stairs and landings. Although there are types that work as all-rounders (such as our Tredaire Softwalk 9mm and Tredaire Sensation 11mm) there will be a slight compromise on comfort in some rooms. You need something denser for stairs and landings so it can handle the foot traffic, whereas in bedrooms and living spaces the priority is comfort. To plan out the flooring for your house, have a look at our different options on the site, and please feel free to get in touch with any questions you might have that can’t be answered on this page.
What is the best carpet underlay to use?
As with any product there are a few important variables to consider when trying to decide which one will work best for you. The following all need to be considered:
Room – which room is the floor going in? Generally stairs, halls and landings need a denser product to cope with foot traffic, while bedrooms and living areas need warmth and comfort. Kitchens and other rooms also benefit from underlayment with moisture control that can work well with laminate or tile floors.
Floor type – under what sort of floor material will it be placed? This will determine what thickness and material will work best in the room, and there is more advice in these FAQs and elsewhere on the site to help you choose the best option.
Thickness – the thickness will be different for a variety of needs and purposes.
Tog rating – the higher the tog rating, the more thermal insulation it provides – keeping your rooms warmer.
Noise reduction level – if reducing noise of impacts and foot traffic is important, then make sure to pay attention to the noise reduction decibel level.
Delivery conditions – sometimes you need your delivery fast, and we offer a rapid courier delivery service that can deliver your product on the most suitable day for you.
Price – the all important one! Our prices are highly competitive and we do our best to pass on any savings to our customers. Take a look at our products today and see of you can find one that works for you.
What is the best underlay for a bedroom?
Bedrooms should be relaxing and comfortable places, so need one that makes the floor feel great in socks or bare feet. We usually recommend the Underlay4u Thick 12mm – it provides excellent softness at a great price. Alternatively, our Tredaire Dreamwalk 11mm offers excellent comfort, warmth and sound proofing qualities.
What is the best underlay for a living room?
We believe that the best kind for a lounge or living room is Underlay4u Thick 12mm. The living room is a place where we spend so much leisure time, and often entertain guests, that it deserves a comfortable floor that makes it easier to relax and unwind. Another great choice is our Tredaire Dreamwalk 11mm, which is a little thinner but still makes the floor of any living room warm and soft under foot and is one of our best sellers.
What is the best underlay for a kitchen?
Most kitchens have wooden, tile or laminate floors, and need a material that will be able to provide warmth and noise reduction through the hard materials, while handling moisture. For your kitchen we recommend Super Gold or DPM Combat Plus 3mm. Both materials are able to retain heat and reduce noise, and also have a built in vapour barrier in the form of a damp-proof membrane to handle dampness.
What is the best underlay for a hall, landing or stairs?
Landings and stairs see a lot of traffic in a day, but they aren’t usually rooms where people tend to hang around. People often ask what is the best for stairs as the choice isn’t an easy one. You need one that is durable, with high enough density to take the foot traffic, thick enough to feel warm and comfy, but thin enough to give a nice finish when it is shaped to fit over steps. To achieve this balance we recommend our 9mm Magic Carpet Underlay – it does the job, in style! Another premium option is our Ultra Step 9mm, which features dense foam and excellent durability.
What is the best underlay for a room on a budget?
We know that re-modelling a house can be an expensive time – costs can quickly add up when you start spotting all of the different things you would love to fix, change or buy! We often field customer queries from people who want to know what is the best and cheapest, and we like to help whenever we can. To save some of the financial headaches we think that you should be able to buy cheap but high quality that meets your needs. So, when it comes to picking for a room on a budget we recommend either Thick 12mm Carpet Underlay or our Magic Underlay 9mm – both offer excellent comfort at a fantastic price.
What is the best underlay for a concrete or tile floor?
For hard floors you need one that is able to provide warmth and noise reduction through thick flooring, while also being able to deal with dampness. For concrete and tile floors we reccomend Super Gold underlay. This material retains a large amount of heat and features a built-in damp-proof membrane (DPM) that acts as a vapour barrier. Another great option is the DPM Combat Plus 3mm. This is slightly thinner and is made from 100% recycled materials. It also features high levels of warmth, noise reduction and a built in DPM to handle moisture and spills.
What is the best underlay for a laminate floor?
Laminate flooring needs a membrane material that can retain heat, reduce noise and manage moisture effectively. For this floor material we recommend either thicker 5mm Super Gold or thinner Combat Plus 3mm, depending on the space available. Both types are high quality and feature in-built damp-proof membranes (DPM) to block moisture and vapour.
What is the best underlay for a luxury vinyl tile (LVT) floor?
Luxury vinyl tiles are very durable floor material and are available in a wide range of attractive styles. You can make the most of your LVTs with a product that is thin and protective. We recommend the Combat Plus 3mm which has a 3mm thickness and a built in damp proof membrane that provides a moisture and vapour barrier.
What is the best underlay for noise reduction?
Plenty of our customers want to reduce the noise that their floors generate. Perhaps your upstairs rooms are being stamped all over by noisy kids, or maybe you live in a flat and want to reduce the noise for downstairs neighbours. For the best noise reduction performance we recommend Tredaire Colours Red. This is a sponge rubber carpet underlay with a thickness of 11.4mm. It has a sound proofing capability of 46db, for the highest levels of noise reduction. An alternative option at a lower price is the Trediare Dreamwalk, which also acts as an excellent barrier to excess noise.
Which underlay is best to cover a ceramic tile floor?
Properly covering over ceramic tile floors with new carpets or other kinds of flooring can be tricky. Tiles may not have been originally fixed all at exactly the same height and sometimes the grout lines can show through a newly laid carpet that is supposed to cover them, making the floor uneven or lumpy. In order to give your floor a comfortable and even finish over ceramic tiles we recommend our Tredaire Dreamwalk 11mm. The thickness and high quality material will help ensure the ceramic tiles are covered consistently across the room.
How much underlay do I need?
Make sure you order just the right amount by calculating the area of your floors. We offer a simple calculator on our home page that will show you how to do just that. The calculator can be used in metres, centimetres or feet. Calculating how much you need for stairs is a bit trickier. On this blog post we walk you through exactly how to work out the amount you need so you can save time and money.
What’s the easiest way to fit my underlay?
There are a few different ways (and we recommend speaking to experienced carpet fitters if possible) but the easiest, depending on what sort of flooring you have, is to use double-sided tape.
Do you sell carpets?
Unfortunately we do not sell carpets. It may be something we offer in teh future, but right now, we consider ourselves underlay specialists and work hard to seek out the best possible products to fit with carpets as well as with all other kinds of flooring that might be used around the home.
What is underlay?
It is a piece of material that is placed under different types of flooring. The characteristics of the material, such as what it’s made from, thermal properties, sound reduction and density all vary from product to product.
The different characteristics are all suited to different types of flooring and environments.
Why should I buy underlay?
Many of our customers first came to us asking “do I need underlay”? Well, we’re obviously a bit biased, but we think that purchasing underlay is a great choice for many different room and floor types. Primarily, we think you should consider buying underlay for the following reasons:
It absorbs the pressure of foot traffic, and reduce wear and tear on floors and carpets,
Underlay provides thermal insulation to help keep your rooms warm and comfy,
It can reduce foot traffic and impact noise,
Underlay can smooth out any inconsistencies or imperfections below your flooring,
It can help provide your home with a real luxury feeling,
Underlay helps floors retain their appearance by reducing flattening.
Why is underlay needed?
It’s primarily needed to protect your flooring, as it absorbs shock from foot traffic. However, other than prolonging the life of your carpet, there are other benefits such as:
• Sound reduction
• Heat insulation
• Under foot comfort
What are the different types of underlay?
There are many different types to suit every environment. Here are some of the areas you should be using it:
• Hotel lobby
• Function room
• And much more!
When it comes to what underlay is made from, here are some of the top ones:
• PU foam
• Sponge rubber
• Crumb rubber
What is the difference between PU foam and sponge rubber underlay?
There are a few notable differences between PU foam and sponge rubber, and both are suited to different rooms and types of flooring. To find a full breakdown of these two materials, you can read our PU foam vs Sponge Rubber comparison.
Can underlay be soundproof?
Technically, it can not be soundproof. There are two types of noise: airbourne and impact noise. It can reduce impact noise reduction, but is not designed to reduce airbourne noise.
To find out what airbourne and impact noise is and how to reduce sound in your home, you can find more information on our Guide to Sound Reduction with Underlay.
What should I consider before purchasing underlay?
There are a few important factors to consider before purchasing, here’s a few things to clear up before making your decision:
• What is my budget?
• Where is the underlay going?
• What is most important to me; comfort, heat insulation, sound reduction, durability or all of the above?
Can underlay be used for laminate flooring?
Yes, it can, and we recommend using it with laminate flooring to prolong the life of the laminate, to provide comfort and it also helps to smooth out an uneven subfloor. You can read more about laminate flooring underlay here.
Can underlay be used for wood flooring?
Yes. It will provide many benefits to your wood flooring such as:
• Even out sub floor imperfections
• Reduces sound
• Offers heat insulation
• Provides comfort
• Aids in moisture resistance
Can I use old carpet as underlay?
We don’t recommend using old carpet or re-using old underlay. This is because carpet is not designed to protect flooring and won’t absorb shock from foot traffic, which is what ultimately damages flooring. It’s also not a good idea as it may have deteriorated with age and be unable to protect your carpet the same way a new one would.
What can I use for underfloor heating?
There are a few options here for underfloor heating. We recommend using a good one as the heat can damage your new flooring by drying it out. You can find the best products on our guide to underlay for underfloor heating.

The one with the highest tog rating (and hence the highest thermal performance) is the Tredaire Dreamwalk with a rating of 3.13. This makes the Dreamwalk an excellent choice for colder rooms or dealing with those winter months.
What is the best underlay to cover old and draughty floorboards?
If you are renovating an old cottage or house with wooden floorboards then you know about the importance of ensuring a warm floor. Draughts can enter the room through gaps in the floorboards which need to be covered with a thermally insulating and comfortable product that doesn’t break the bank. For this purpose we recommend the Super Gold 5mm. In addition, it can also help if you put a layer of lining paper over the boards for a little extra protection.
