10mm Carpet Underlay: PU Foam, Underfloor Heating & More
An underlay of this thickness offers a wide range of benefits. It not only helps to smooth out the subfloor and make carpets feel softer underfoot, but also protects the flooring against premature wear and tear by reducing movement and absorbing pressure. This then helps to extend the lifetime of the flooring.
Some of the most popular items for sale in this product category include:
- 10mm carpet underlay – 42oz Wool Fibre, ThermalStream, Super, Heart n Soul, QA Breathe, Tredaire Palladium, Tredaire Zest, Tredaire Lifestyle
- 10mm acoustic underlay – Tredaire Palladium (43dB), Cosi 10 (44dB), Wilsons Plushwalk (45dB), ThermalStream (46dB)

While we don’t supply 10mm laminate underlay, as underlay for laminate, wood, or vinyl flooring tends to be thinner, the thickest laminate underlay options we sell are 7mm thick.
Maybe you’re looking for an insulating 10mm carpet underlay? The best products will have a Thermal Overall Grade of 2.5 or higher, such as Tredaire Zest (2.64 TOG), Cosi 10 (3.0 TOG), and Wilsons Plushwalk (3.2 TOG). The highest TOG rating currently available is our 3.4 TOG 42oz wool fibre underlay.
However, if you have an underfloor heating system, it’s important to choose a compatible 10mm thick underlay, such as ThermalStream.

Frequently Asked Questions
A 10mm thick carpet underlay is ideal for areas of the home or private offices where comfort and luxuriousness are a priority, such as lounges, living rooms, and bedrooms.
However, this thickness may not always be suitable for busy areas with heavy foot traffic, such as stairs and hallways, unless it’s also a high-density underlay. In these cases, it’s important to choose a hardwearing underlay that offers firm support, such as Cloud 9 Super Contract Underlay, which is also recommended for commercial installation.
While 12mm underlay may be too thick for stairs, 10mm should be stable enough to not round the edges and create a trip hazard.
Our 10mm acoustic underlay options are also a great choice for multi-storey buildings, such as flats or offices, to provide comfort while reducing noise transmission between floors.
Whether you’re looking for cheap 10mm underlay to suit a tight budget or just need to work out how much to buy regardless of the price, we can help make the process faster.
Carpet Underlay Shop has a handy flooring measurement calculator you can use to calculate the amount of flooring or underlay you need to cover the room. Once you’ve taken the measurements, you can enter them in either feet or metres to generate the area you’ll need to cover.
As we list underlay roll prices by square metre, we would recommend using metres to make it easy to calculate the number of rolls you need to buy.
Once you know the area, you can divide it by the amount in an underlay roll – which could be a full roll (15.07m2), a half roll (7.5m2), or even a mini roll (5m2). This will tell you how many rolls you need (we would recommend rounding to the nearest roll or half roll where possible).
Since we also show the price per roll, you can then see how much it will cost to buy the amount of underlay you need, depending on the individual product.
Our luxurious PU foam underlay can offer excellent thermal insulation as well as a softer underfoot feeling, which makes the room feel warmer and more comfortable.
We stock several luxury 10mm underlays at Carpet Underlay Shop. These include the Cosi 10 Underlay, made from thick PU sponge, and Tredaire Lifestyle Select Underlay, which is actually 10.2mm thick and made from durable yet bouncy sponge rubber.
However, if the maximum thickness you’re looking for is 10mm and you want the softest cushioning underfoot, we recommend Wilsons Plushwalk 10mm.
We believe Plushwalk 10mm underlay offers the best value for money for a premium product in this collection, as the memory foam retains its shape better than standard PU foam and sponge rubber alternatives, delivering a longer life for your underlay and flooring.
At Carpet Underlay Shop, our delivery timelines and charges depend on the service you choose when you place your order and the total order value. We offer economy and premium delivery services, which can take 2 to 3 working days and 1 working day, respectively.
Please note that this also depends on when we dispatch your order, not when you receive your order confirmation. We send out orders on the same day if they're placed on a working day before 2pm, but orders placed after 2pm won’t be dispatched until the next working day.
Additionally, while we typically deliver across the UK mainland within these timeframes, alternative arrangements and surcharges may be required for orders to be shipped to the Scottish Highlands, Offshore Islands, or Northern Ireland. Deliveries to these locations will therefore take longer.
If delivery to your address isn’t available when you try to check out after adding products to your basket, please contact us.
Customers are welcome to get in touch to discuss our delivery services, including the possibility of international shipping, and our team will do everything we can to help.
