Most homeowners spend weeks agonising over carpet samples only to spend thirty seconds choosing the underlay that actually supports them. It’s a common mistake that leads to expensive carpets flattening in less than five years or bedrooms that feel like ice boxes during a British winter. You likely want that deep, hotel-style comfort underfoot, but you’re probably also tired of hearing every footstep from the rooms upstairs. It’s frustrating when a new floor doesn’t deliver the quiet sanctuary you expected.

What is Cloud 9 Underlay and Why Does It Matter?
Cloud 9 is the UK’s leading brand of polyurethane (PU) foam underlay. You might recognise the name from the world of hair styling tools, but for flooring professionals, it’s the benchmark for quality beneath your feet. We should clear up that common mix-up immediately. While the name shares a title with a popular brand of straighteners, this product is strictly for your floors. We believe in being direct about your investment. Choosing a high-quality underlay is just as vital as the carpet itself.
It acts as a shock absorber. Without it, the friction between the carpet backing and the hard subfloor causes premature wear. A quality foam layer can increase the lifespan of your carpet by as much as 50 percent. This makes it a sensible financial choice rather than an optional extra. Professional fitters across the country prefer this brand because it offers a reliable balance of comfort and durability that cheaper alternatives simply cannot match.
The Origins of Cloud 9 by Ball & Young
Ball & Young, based in Corby, Northamptonshire, changed the industry when they introduced this foam technology in 1994. They moved the market away from the heavy, cumbersome rubber products that dominated the 1980s. Their British-based manufacturing facility operates under the ISO 9001 quality management system. For a homeowner, the “Made in Britain” label guarantees that the product meets strict safety standards and hasn’t been damaged by months of compression in a shipping container.
PU Foam vs. Traditional Rubber Underlay
The technical advantages of PU foam over traditional rubber are straightforward. A standard 11mm roll of cloud 9 weighs roughly 15kg, making it significantly easier to handle than a 30kg roll of crumb rubber. This lightness doesn’t sacrifice performance. Most cloud 9 products are manufactured using 80 percent recycled materials, such as furniture offcuts. While old rubber underlays often crumble and lose elasticity after a decade, PU foam retains its “bounce” and thermal insulation properties for much longer.
The Science of Comfort: Tog Ratings and Decibel Reduction
Tog rating is the thermal resistance measurement used to keep heat in a room. While many homeowners focus solely on how a carpet feels underfoot, the technical specifications behind the scenes determine how your home actually performs. A common mistake is assuming that a thicker underlay is automatically a better one. In reality, density plays a far more critical role in longevity and support. High-quality options like cloud 9 are engineered with specific densities to prevent the material from collapsing under heavy foot traffic over a 10 to 15-year period.
Thermal Insulation: Keeping Your Home Warm
Cloud 9 acts as a highly effective second layer of insulation beneath your carpet. Ground floors, particularly those with draughty floorboards or cold concrete slabs, require a higher tog rating to prevent heat loss. We typically recommend a rating of 2.5 to 3.1 togs for these areas. Upstairs rooms, which benefit from heat rising from below, can often manage with a lower rating of 1.5 to 2.0 togs. You must be careful with underfloor heating, though. Using a high-tog underlay on top of an underfloor system can act as a barrier, trapping the heat under the floor rather than letting it warm the room. For these systems, you’ll need a specialist low-tog underlay, usually below 1.0 tog, to ensure the system remains efficient.
Acoustic Performance: Peace and Quiet
Impact noise is the sound of footsteps or dropped objects travelling through the floor structure; air-borne noise refers to voices or television sounds. Cloud 9 underlays are a top choice for tackling impact noise, with many products in the range offering a significant reduction of 39dB to 43dB. This makes them the go-to choice for flats or busy multi-storey homes where silence is a priority. If you’re unsure which rating suits your specific subfloor, you can ask us for a straightforward recommendation based on your home’s layout. Choosing a high-decibel rating ensures that the thud of a heavy footstep on the landing doesn’t sound like a drum kit in the kitchen below. It’s about creating a living space that feels as quiet as it does comfortable.
Comparing the Cloud 9 Range: Cirrus, Cumulus, and Beyond
Selecting the right cloud 9 underlay involves more than just picking the thickest foam available. To be frank, putting an 11mm luxury underlay on a steep staircase is a mistake we see too often; it makes the carpet difficult to fit and can create a safety risk. The range is designed with specific rooms in mind, using recycled PU foam to balance environmental impact with home comfort. Most homeowners will find their ideal match between the 7mm and 11mm options, depending on the traffic levels of the room.
- Price vs. Performance: You don’t need luxury underlay in every room. Splurge on the areas where you sit and relax, but choose durability over depth for the “motorways” of your home, like the landing and stairs.
- Thickness Levels: A 2mm difference might sound small, but it changes the Tog rating and sound impact significantly.
Cloud 9 Cumulus: The Luxury Standard
The 11mm Cumulus is currently the UK’s best-selling luxury underlay. It is designed for maximum comfort in lounges and bedrooms. With a high 3.10 Tog rating, it acts as a brilliant insulator for cold subfloors. It also offers a 43dB impact sound reduction, which is perfect for silencing heavy footsteps in upstairs rooms. It’s the right choice when you want that “sinking into the floor” sensation after a long day.
Cloud 9 Cirrus: The Versatile All-Rounder
The 9mm Cirrus is our top recommendation for high-traffic areas. It feels slightly firmer than the Cumulus, which is exactly what you want on stairs and hallways. It provides a 39dB sound reduction and a 2.60 Tog rating. Because it is denser, it supports the carpet backing better in areas where people walk most frequently. This prevents the carpet from stretching or “rucking” over time, ensuring your fitting stays crisp and professional.
Specialist Options: Super Contract and Radiance
Standard underlay can act like a thermal blanket, which is a disaster if you have underfloor heating. In these cases, we recommend Cloud 9 Radiance. It is 7mm thick with a low 1.10 Tog rating, allowing heat to circulate into the room rather than being trapped. For commercial spaces or home offices with heavy castor chairs, the 10mm Super Contract is the best bet. It is engineered to withstand extreme pressure without losing its shape, providing a reliable foundation for years of heavy use.
Fitting Cloud 9 Underlay: A Guide for Homeowners
Frankly, skipping the subfloor preparation is the quickest way to ruin a premium product. Before you even think about unrolling your cloud 9 underlay, the floor beneath must be spotless. A single 2mm piece of grit or a stray staple can eventually wear a hole through the foam and the carpet above. Ensure the surface is dry, level, and free of old adhesive. If you’re fitting over floorboards, check for any that are loose or protruding, as these will cause squeaks that no underlay can fully silence.
The debate over which way up to lay the material is a common one. For most cloud 9 products, you should lay the branded, film-covered side facing upwards. This isn’t just for marketing. The film allows the carpet to slide easily into position during the final stretch, preventing the foam from snagging or tearing. Laying it upside down makes the fitter’s job significantly harder and can lead to an uneven finish.
You’ll need a specific kit to achieve a professional result. Avoid using kitchen scissors; instead, invest in a heavy-duty utility knife and a pack of fresh blades. A sharp bolster is also vital for tucking edges into the grippers. To prevent the underlay from shifting, use a staple hammer for timber floors or a high-quality spray adhesive for concrete. Using the wrong fixative can lead to the underlay “creeping” over time, which often voids the 10-year manufacturer warranties provided by many carpet brands.
Preparation and Layout
Accurate measurements are your best friend. Add a 10cm margin to every wall to ensure you aren’t left short after trimming. Secure your carpet grippers roughly 6mm away from the skirting boards before laying the underlay. When you lay the rolls, ensure they butt up tightly against each other without overlapping. An overlap as small as 3mm will create a visible ridge through the carpet that you’ll feel every time you walk across the room.
Taping and Securing
Joining the sections requires professional-grade 50mm wide underlay tape. Don’t rely on standard packing tape; it lacks the longevity to withstand years of foot traffic. Tape every single seam to create a single, unified cushion. This prevents dust from rising through the floorboards and keeps the underlay from moving. When trimming around radiator pipes, cut a small ‘V’ shape to allow the material to sit flush against the floor without bunching up. If you’d prefer an expert to handle the technicalities, you can book a professional fitting service to ensure your home’s foundation is perfect.
Is Cloud 9 Worth the Investment? The Final Verdict
The short answer is yes. While budget sponge or felt alternatives might save you £40 on a standard room today, they often lose their bounce within 36 months, leaving your carpet looking tired and flat. High quality underlay acts as a vital shock absorber for your flooring. It specifically prevents carpet pile reversal, a common issue where heavy foot traffic crushes the fibres permanently and creates unsightly shading. By maintaining this resilience, cloud 9 underlay can extend the aesthetic life of a £1,200 carpet by up to 50%.

Frequently Asked Questions
Can I use Cloud 9 underlay with underfloor heating?
Yes, you can use specific cloud 9 products like the Radiance range for underfloor heating. It has a low 0.8 TOG rating, which allows heat to pass through into your room efficiently. Standard 11mm versions have a 3.1 TOG rating. This is far too insulating and would prevent your heating system from warming the space effectively, potentially leading to higher energy costs and a cold room.
Which Cloud 9 underlay is best for stairs?
Cloud 9 Cirrus is the most reliable choice for your staircase. It is 9mm thick and has a high density that prevents the material from collapsing over the stair nosing. This density ensures the carpet remains taut for the long term. Using a thinner, firmer product prevents the carpet from loosening over time, which is a primary cause of trip hazards on stairs in busy UK homes.
Which side of the Cloud 9 underlay should face up?
You should always lay the underlay with the printed or film side facing upwards towards the ceiling. This side is designed to let the carpet move slightly during the fitting process, making the job much easier. The flatter, plain side grips the subfloor. This prevents the carpet from shifting once you start walking on it, ensuring a stable and long-lasting finish that won’t require early correction.
How long does Cloud 9 underlay last compared to rubber?
Cloud 9 underlay typically lasts for the entire lifespan of your carpet, which is usually 12 to 15 years. Unlike old-fashioned crumb rubber that can start to perish and turn to dust after 7 or 8 years, PU foam remains resilient. It keeps its spring and structure throughout its service life, meaning you won’t need to replace it until you buy a new carpet for your home.
Does Cloud 9 underlay help with cold floors?
It’s a brilliant solution for cold floors because of its high thermal resistance. Frankly, using an 11mm cloud 9 underlay can improve heat retention by approximately 15% compared to laying carpet directly on a cold concrete subfloor. It acts like a thermal blanket for your room, helping to lower your energy bills while making the floor feel significantly warmer underfoot during the winter months.
Is 11mm Cloud 9 underlay too thick for some carpets?
Yes, 11mm can be too thick for very deep pile carpets or rooms with low-hanging doors. If your carpet is 18mm thick, the total height reaches 29mm. You’ll likely need to trim 10mm off the bottom of your doors to ensure they swing freely without catching. For areas with limited clearance, we often suggest a 9mm alternative to avoid the need for extra joinery work on your doors.
Can I fit Cloud 9 underlay myself or do I need a pro?
You can fit it yourself, but we recommend a professional for a seamless finish. A professional fitter usually charges around £4 per square metre and possesses the specialist tools required for proper stretching. If you attempt it yourself, you risk leaving small bumps or loose areas. These mistakes can cause your carpet to wear out prematurely within just 24 months, leading to a much higher cost in the long run.
Is Cloud 9 underlay made from recycled materials?
Every roll is manufactured from 100% recycled scrap PU foam. This material is salvaged from the furniture and automotive industries, preventing thousands of tonnes of waste from entering the system. It’s also 100% recyclable at the end of its life. This makes it a responsible, sustainable choice for UK homeowners looking to reduce their environmental impact during a renovation while still enjoying high-quality comfort underfoot.
