Best Underlayment For Every Floor

Dealing with a floor that’s annoyingly loud or constantly creaks underfoot? 

Picking the right underlayment can solve those problems before they start. It’s not glamorous, but it’s needed. 

Think of underlayment as the foundation that ensures everything above it works seamlessly—quiet, comfortable, and durable. 

It’s time to stop walking on eggshells. Let’s get your floors in top shape from the ground up.

Key Notes

  • The right underlayment can silence creaks and block moisture, boosting floor durability.
  • Hardwood, laminate, vinyl, and tile all require different underlayments for optimal performance.
  • Cork and rubber offer superior soundproofing for noisy, high-traffic areas while foam underlayments often include built-in moisture barriers for extra protection.
  • Choosing the wrong underlayment risks warping, cracking, and discomfort underfoot.

    Why Underlayment Matters More Than You Think

    You wouldn’t build a house without a strong foundation, would you? Similarly, a floor without a good underlayment is a recipe for disaster. 

    Let’s break it down:

    Sound Reduction

    The right underlayment, especially cork or felt, can significantly reduce noise from footsteps and echoes in a room. 

    This helps create a quieter, more peaceful home environment by dampening sound transmission through the floor.

    Moisture Protection

    The right underlayment, especially cork or felt, can significantly reduce noise from footsteps and echoes in a room. 

    This helps create a quieter, more peaceful home environment by dampening sound transmission through the floor.

    Thermal Insulation

    Don’t you love it when your floor is cozy beneath your feet? Underlayment can help with that too, especially if you’re living in a colder climate or have floors directly above an unheated garage. 

    Cork, foam, and rubber underlayments offer some thermal protection, making your space warmer and more comfortable.

    The Best Underlayment for Every Type of Floor

    Now that we know why underlayment is so important, let’s figure out which type is best for the different floors in your home. 

    Spoiler: There’s no one-size-fits-all. 

    Each flooring type has its own needs, and the wrong underlayment can cause a whole mess of problems, from squeaks to moisture damage.

    1. Hardwood Floors: The Classics Need Special Care

    Hardwood is the floor we all dream of—timeless, elegant, and beautiful. But, like all beauties, it’s a bit high-maintenance. The underlayment you choose here can make or break the longevity of your wood floors.

    Solid Hardwood Floors

    Solid hardwood floors are a bit fussy when it comes to moisture. They’ll expand, contract, and warp if exposed to too much of it. 

    So, the underlayment you choose needs to provide both cushion and moisture protection. Felt, cork, and foam are popular options. 

    Cork is especially good if you want to reduce noise—it absorbs sound like a dream, making it ideal for upper floors. But felt is no slouch either. It offers excellent moisture protection, especially when paired with a separate vapor barrier.

    Engineered Hardwood Floors

    Engineered hardwood is like solid hardwood’s low-maintenance cousin. It’s more resistant to moisture, thanks to its layered construction, but that doesn’t mean it doesn’t need a little help. 

    Cork and felt underlayments are again your best bet here, providing soundproofing and a bit of extra comfort underfoot.

    2. Laminate Flooring: Affordable and Stylish, But Needs Some TLC

    Laminate flooring has come a long way from the tacky faux-wood look of the past. Nowadays, it can mimic hardwood so convincingly that even flooring snobs have to do a double-take. 

    But without the right underlayment, laminate floors can be noisy, hollow, and uncomfortable to walk on.

    Foam Underlayment

    Foam is the go-to underlayment for laminate floors because it’s affordable, lightweight, and gets the job done. 

    High-density foam underlayment helps reduce the hollow, echoey sound that laminate floors can produce. It also provides a cushion that makes walking on laminate feel softer and more comfortable.

    Cork Underlayment

    If you’re looking for something a bit more eco-friendly (and luxurious), cork is a fantastic option. It’s naturally antimicrobial, which means it can help resist mold and mildew in slightly damp areas like kitchens. 

    Plus, cork is excellent for soundproofing. If you have kids running around, this will save you from that constant "thud, thud, thud" of tiny feet.

    3. Vinyl Plank Flooring: The Durable, Do-It-All Floor

    Vinyl plank flooring has become a favorite for high-traffic areas because it’s durable, water-resistant, and stylish. But it needs the right underlayment to stay that way.

    Foam or Rubber Underlayment

    Foam is often the first choice for vinyl planks. It’s affordable, easy to install, and helps with noise reduction. Plus, foam underlayments usually come with moisture barriers, which are crucial for keeping water from seeping into your subfloor. 

    Rubber is another solid choice, especially if you’re installing vinyl in a high-traffic area like a kitchen or hallway. It’s tougher than foam and provides better soundproofing.

    Cork Underlayment

    Want an underlayment that’s good for the environment and good for your home? Go with cork. It’s naturally resistant to mold and mildew, which makes it perfect for areas where water might be a problem. 

    Plus, it’s fantastic at absorbing sound, so your vinyl plank floors won’t sound hollow underfoot.

    4. Tile Flooring: Tough as Nails, But Needs Support

    Tile is the heavyweight champ of flooring—durable, stylish, and practically indestructible. But even tiles need a little help from underlayment, especially when it comes to preventing cracks and ensuring long-term stability.

    Cement Board or Plywood

    For tile floors, you want something that can take the weight. Cement boards and plywood are the perfect partners here. They provide a rigid, stable surface for the tiles, preventing them from shifting or cracking. 

    Cement board is especially useful in moisture-heavy areas like bathrooms and kitchens, as it’s mold-resistant and water-repellent.

    Uncoupling Membranes

    If you live in an area where the foundation might shift a little (or if you’re just worried about cracks), uncoupling membranes are a game-changer. 

    These nifty underlayments allow a bit of movement between the subfloor and the tiles, which means fewer cracks and a longer-lasting installation.

    The Case for Moisture Barriers: Do You Really Need One?

    Let’s cut to the chase—yes, you do. 

    If your floor is anywhere near moisture (think bathrooms, kitchens, basements), you need an underlayment with a moisture barrier. 

    For wood floors, this is especially important. Even engineered hardwood can warp if exposed to too much water. In high-humidity areas, a vapor barrier is non-negotiable.

    Frequently Asked Questions

    Can I install underlayment on top of existing flooring?

    Yes, in many cases you can, but it depends on the type of flooring and the underlayment material. Foam and cork can usually be installed over old floors, but rigid options like plywood or cement board may require removal of the existing floor.

    Does underlayment affect floor height?

    Yes, underlayment can slightly raise the floor height. This is important to consider in rooms where doors may need to be trimmed or thresholds adjusted.

    Is it necessary to use underlayment with attached pad flooring?

    If your flooring already has an attached underlayment, adding another layer isn’t usually necessary and could cause issues like trapping moisture or creating an overly soft surface.

    Can underlayment help with uneven subfloors?

    Underlayment can smooth out minor imperfections, but for larger issues, you may need to level the subfloor first to avoid problems like floor sagging or buckling.

    What’s the best underlayment for heated floors?

    For heated floors, look for underlayments that are designed to withstand heat transfer, such as specialized foam or cork. These will ensure that the heat distributes evenly without causing damage.

    Conclusion

    In the end, your choice of underlayment will make a world of difference to your floors. It controls moisture, reduces noise, and even improves comfort underfoot. 

    Each type of flooring—whether hardwood, laminate, vinyl, or tile—has specific underlayment needs that shouldn’t be overlooked. The right choice will protect your investment and extend the life of your floors.
