Vinyl floor underlayment is the silent hero beneath every beautiful floor, providing that extra layer of support and protection you need to maintain long-lasting beauty and enduring performance of your new flooring. The correct underlayment can reduce footfall and airborne noise, both common challenges for LVT; in a click-lock format it offers a durable level surface to support the joints from stress and potential early failure. Sheet vinyl might be able to ignore it, but LVT benefits from being able to get angry. Here, at 2ndflooring we demystify what to select and why it pays off.
Does vinyl flooring need underlayment
It varies a lot depending on the kind of vinyl you are installing and how your subfloor is laid out. In fact, most vinyl flooring does not require an underlayment but it will still provide a number of benefits from adding cushioning to reducing noise and moisture protection, especially in the case of our Armor Core and Elemental styles or with floating click-lock LVT/LVP.

The true decider: your vinyl type
1) Click-lock LVT/LVP (floating planks/tiles)
A common question is “Do I need underlayment for vinyl plank flooring? “Floating floors and attached floors feel and sound different.” Underlayment is typically recommended (and sometimes even required!) for click-lock vinyl because it:
- cushions the floor underfoot
- helps quiet footfall and echoes
- can serve as moisture shield (in particular on concrete)
- for stability and helps support the locking mechanism by providing a uniform base
2) Sheet vinyl
Sheet vinyl usually does not require an underlayment in the “roll-out foam” sense. Instead, what it typically requires is a smooth, steady and very clean surface. For many contractors, the smoother the subfloor is (either with a suitable panel underlayment or skim coat), the better — not necessarily adding more cushion.
3) Glue-Down Vinyl (LVT/LVP glued to subfloor)
Glue-down products are generally not recommended to be installed over soft foam cushion because it can affect adhesion. For us, the priority is a correctly prepared subfloor — flat, dry and sound.
Luxury vinyl plank flooring underlayment
The LVP underlayment will be the last layer that lays between the subfloor and your LVP planks, which can impact how well your flooring adheres and how it operates on a day-to-day basis. As luxury vinyl has taken off as the go-to flooring option that’s waterproof, pet proof, and life proof, homeowners and property managers have started paying more attention to what’s going on under the planks—because moisture vapor, noise transfer, and long-term durability still matter.

What is underlayment for LVP?
Underlayment: The underlayment consists of a thin layer of foam, cork or felt that’s laid down on the subfloor before the vinyl is installed. It can also add cushion underfoot, minimize echo and footstep noise, and offer moisture protection — especially with concrete.
Even if your LVP has an attached pad, you can still benefit from installing a luxury vinyl plank flooring underlayment. Many attached pads are pretty basic and more about convenience than performance, so an underlayment specifically made for LVP can help you to upgrade sound control and stability when it’s approved by the manufacturer.
Plywood underlayment for vinyl flooring
Many vinyl flooring installation projects can benefit from bontrup agent avoiding rough conditions and the need to replace the subfloor due 53/32 aspx Plywood Underlayment Many circumstances exist when you might need to use plywood as an underlayment. As installed over a structural subfloor, plywood underlayment provides an excellent foundation and helps to minimize any contour irregularities in the existing subfloor to avoid telegraphing. Usually made from sanded face, exterior grade plywood, it comes in various thicknesses between ¼ inch and ½ inch depending on the floor system and condition of the subfloor. If secured, ready-leveled, and moisture tested when installed, plywood underlayment will enhance the life of both new and old floors by reducing wear, which in turn minimizes scratching as well as early failure on joints making it a great substrate for luxury vinyl tile.
Do you need underlayment for vinyl flooring
Most contemporary types of vinyl flooring such as glue-down and sheet vinyl do not need an underlayment. these floors are made to be installed on a clean, dry and smooth subfloor that is free from moisture. But for click-lock or floating vinyl plank flooring, underlayment is usually not only a recommendation, but also preferred as it offers sound reduction and in most cases will be needed to prevent your subfloor from getting any wavy areas over time. Certain vinyl planks are directly backed with pad and may not require an additional underlayment. Instruction of installing is not included.
Best underlayment for vinyl plank flooring
Vinyl flooring underlayment is essential for many different aspects of your floor, even if you’ve already been provided with an attached pad. Placed between the subfloor and your vinyl floor covering, underlayment is successful in managing moisture vapor, dampening impact and airborne noise as well as added cushion (with a slight giving/flex beneath the flooring so surface does not make contact with underlying subfloor) and reducing deflection (the up/down movement or “bouncy” feeling when walking on the floor; if within specification of product). Though certain vinyl products can be laid directly on a smooth surface, the right underlayment- lightweight, thin, and rubberised for product specific-layers is especially useful over concrete and in two-story homes where sound may carry. But whether the wrong kind or too many, the wrong combination of layers can potentially damage locking systems and floorsiles while also voiding a product warranty so it is crucial that owners adequately consider which pad to purchase.
Foam vs cork underlayment for vinyl flooring
| Feature | Foam Underlayment | Cork Underlayment |
| Sound Absorption | Moderate sound reduction, better for soft impact noise | Excellent sound reduction, especially for impact noise |
| Moisture Resistance | Not a moisture barrier, can trap water and cause mold | Not ideal for moisture-prone areas, but offers moderate resistance to water when properly sealed |
| Comfort/Cushioning | Adds cushioning, but can feel soft and spongy over time | Offers a firm cushion, but not too soft for better stability |
| Durability | Can compress over time, losing effectiveness | Durable, resists compression, and lasts longer with proper installation |
| Environmental Impact | Typically made from synthetic materials | Made from natural, renewable resources, more eco-friendly |

Best soundproof underlayment for vinyl flooring
The Importance of Soundproof Underlayment in Residential and Commercial Spaces Soundproof underlayment is an essential material for decreasing noise to provide comfort whether dealing with a residential or commercial space, particularly those with multiple floors. Fitted beneath floor coverings, it will reduce impact noise, such as footsteps, and airborne sound transmission between stores. When it comes to all possible alternatives, rubber underlayment soundproofing would definitely top the list due to its density as well as staying power. It has excellent sound-absorbing properties, it’s non-crush design maintains its plushness in high traffic areas and being made of polypropylene makes treated with good water-, stain- and fade-resistant; even provides protection against mildew. With recycled material content increasing, rubber underlayment can help contribute to LEED certification and a healthy indoor environment And better indoor air quality is made easier with rubber Underlayment’s They offer a clever, long-term, eco-responsible solution for outstanding acoustical control.
