In those cases, adding another layer isn\u2019t just unnecessary\u2014it can sometimes interfere with the locking system or make the floor feel unstable.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, when LVT comes without that built-in padding, <\/span><a href=\"https:\/\/kofflersales.com\/category\/floor-underlayment\"><span style=\"font-weight: 400;\">underlayment<\/span><\/a><span style=\"font-weight: 400;\"> can be valuable. It cushions each step, reduces echo in the room, and can serve as a moisture barrier if installed over concrete. The need for underlayment ultimately depends on the product and the environment where it\u2019s being installed.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span style=\"font-weight: 400;\">Key Takeaways<\/span><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Not all LVT requires underlayment; it depends on the product and subfloor.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Built-in pads often replace the need for separate underlayment.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Underlayment can improve comfort, sound, and moisture protection.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Manufacturer guidelines should always guide your decision.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The right choice protects both your floor\u2019s performance and your warranty.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2><span style=\"font-weight: 400;\">Factors That Influence the Need for Underlayment<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">One of the biggest considerations is the type of subfloor. If you\u2019re working over concrete, an underlayment with a moisture barrier is often recommended to prevent water vapor from damaging your new flooring. For wood subfloors, the focus is usually on smoothing out imperfections and reducing creaks.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Another important factor is whether your LVT already includes a pre-attached pad. If it does, you\u2019re generally covered. Adding another layer could compromise the installation. If it doesn\u2019t, then underlayment may be worth the investment.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Finally, think about the room\u2019s purpose. Bedrooms and living rooms benefit most from the added comfort and quiet feel of underlayment, while spaces like basements often require it to control moisture.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span style=\"font-weight: 400;\">Manufacturer Guidelines and Warranties<\/span><\/h2>\n<p><a href=\"https:\/\/kofflersales.com\/category\/luxury-vinyl-tile\"><span style=\"font-weight: 400;\">Every luxury vinyl tile brand<\/span><\/a><span style=\"font-weight: 400;\"> provides installation instructions, and those guidelines are crucial.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some will specify that no additional underlayment should be used, while others may recommend or even require it. Ignoring these directions can risk your warranty, leaving you without coverage if problems like warping or separation occur later on.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Checking the manufacturer\u2019s requirements before installation is always the best way to protect your investment.<\/span><\/p>\n<p><a href=\"https:\/\/kofflersales.com\/blog\/top-luxury-vinyl-tile-lvt-brands\/\"><span style=\"font-weight: 400;\">You can read about the top 5 LVT brands here.<\/span><\/a><\/p>\n<p>&nbsp;<\/p>\n<h2><span style=\"font-weight: 400;\">Types of Underlayment That Work with LVT<\/span><\/h2>\n<p><a href=\"https:\/\/kofflersales.com\/product\/cork-underlayment-quiet-comfort\"><span style=\"font-weight: 400;\">Cork underlayment<\/span><\/a><span style=\"font-weight: 400;\"> is a natural option that especially excels in sound absorption and comfort, though less suited for moisture-prone areas.<\/span><\/p>\n<p><a href=\"https:\/\/kofflersales.com\/product\/rubber-cork-underlayment-sound-control\"><span style=\"font-weight: 400;\">Rubber and cork-rubber combo underlayments <\/span><\/a><span style=\"font-weight: 400;\">are denser and more durable, providing superior sound control and impact resistance. The combination of rubber and cork delivers the best of both worlds\u2014rubber\u2019s moisture resistance and cork\u2019s cushioning comfort\u2014making it suitable for both residential and light commercial spaces.<\/span><\/p>\n<p><a href=\"https:\/\/kofflersales.com\/product\/foam-underlayment-ez-floor\"><span style=\"font-weight: 400;\">Foam underlayment<\/span><\/a><span style=\"font-weight: 400;\"> is a lightweight choice that provides a modest cushion and basic noise reduction. It\u2019s easy to install and commonly used in residential applications where cost and simplicity are key considerations.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In areas with potential moisture exposure, look for underlayments with an integrated vapor barrier to protect your flooring investment. And when in doubt, choose an underlayment specifically designed for LVT or LVP flooring to ensure proper support for the locking system and long-term performance.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span style=\"font-weight: 400;\">When Underlayment Is Essential<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Underlayment is essential when you\u2019re installing LVT over concrete without a built-in pad, especially in moisture-prone areas. It also makes sense when your subfloor has slight unevenness that needs smoothing, or in high-traffic spaces where sound reduction is a priority.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On the other hand, if your LVT already comes with a pre-attached pad, extra underlayment isn\u2019t just optional\u2014it may cause more harm than good (e.g., causing issues with stability). Similarly, if your subfloor is clean, smooth, and dry, you can sometimes install directly without any issues.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span style=\"font-weight: 400;\">LVT Performance With and Without Underlayment<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The difference is most noticeable underfoot and in how the room sounds.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">With underlayment, each step feels softer and more cushioned, creating a more pleasant walking experience. The room may also feel quieter, since the underlayment absorbs impact noise and reduces echo. In colder climates, you\u2019ll also notice a bit more insulation underfoot, which can make a room feel warmer.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Without underlayment, the floor still performs well\u2014particularly when the product already has a pre-attached pad. The installation process is faster and more budget-friendly. You\u2019ll still have a durable, attractive floor\u2014just without those extra benefits.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span style=\"font-weight: 400;\">The Value of Adding Underlayment<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">While underlayment does add a bit of cost to the project, the value it provides often outweighs the price. A modest investment per square foot can deliver years of added comfort, quieter spaces, and added protection against moisture or uneven subfloors.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Think of it as more than just an accessory, as an extra layer of insurance for your floor. For many homeowners, it\u2019s worth considering underlayment as an insurance policy. You may not always need it, but when you do, it pays off.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Above all, follow the manufacturer\u2019s guidelines for your specific brand to protect your warranty and get the best results. Pair that with proper subfloor preparation, and you\u2019ll have a floor that looks great, feels comfortable, and stands the test of time.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When you\u2019re ready to get started, <\/span><a href=\"https:\/\/kofflersales.com\/category\/floor-underlayment\"><span style=\"font-weight: 400;\">shop Koffler\u2019s premium selection of underlayment<\/span><\/a><span style=\"font-weight: 400;\"> to find the perfect fit for your project.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span style=\"font-weight: 400;\">FAQs<\/span><\/h2>\n<h3><span style=\"font-weight: 400;\">Can I use carpet padding under LVT?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">No\u2014carpet padding is too thick and soft, and it will interfere with the locking system of your floor.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><span style=\"font-weight: 400;\">Do I need underlayment on a plywood subfloor?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Not always.
