Floors do not exactly lead sheltered lives. They deal with wet shoes, dropped cookware, moving furniture, pets racing through the house, and children who apparently consider every room a playroom.

Then, just as you start looking for a floor tough enough to handle all of that, the acronyms arrive: LVP, LVT, rigid core, HDPC®. The terminology may sound technical, but the differences are easier to understand when you look at what each construction can mean in your home.

Traditional luxury vinyl plank works well in many residential spaces. Rigid core flooring adds greater dent resistance and a thicker, more solid construction. HDPC (High-density polymer core) takes rigid core performance further with an ultra-dense core designed to remain stable through wider temperature changes.

Rigid core is not exactly a niche choice anymore; it has actually become one of the most popular choices in residential flooring. According to Floor Covering News, rigid core accounted for about 75% of the entire residential resilient flooring market in 2024—and an even greater 83.4% of residential LVT sales. And the larger luxury vinyl plank market continues to grow: Fortune Business Insights valued the global LVP market at $8.81 billion in 2025 and projects it to reach $16.01 billion by 2034, with rigid flooring leading the product category.

What Is Rigid Core Flooring?

Rigid core flooring belongs to the luxury vinyl flooring family. Like traditional luxury vinyl plank, it is made in layers that include a protective wear layer, a printed design layer, a core, and a backing layer.

The difference is at the center of the plank. Traditional LVP has a more flexible construction, while rigid core flooring has a strong, solid center that helps it resist dents and maintain its shape.

The wear layer helps protect the floor against scratches, scuffs, and stains. Beneath it, the design layer creates the wood grain, color variation, and other details you see on the finished floor. Low-gloss finishes, wide planks, painted bevels, and realistic surface textures can bring the character of natural hardwood into rooms throughout the home.

Rigid core flooring from Armstrong Flooring® is also 100% waterproof.* The planks will not swell, buckle, or lose their integrity when exposed to water, making rigid core a practical option for kitchens, bathrooms, laundry rooms, basements, and other areas where spills and moisture are simply part of life.

How Is Rigid Core Different from Traditional LVP?

Traditional LVP and rigid core flooring share many benefits. Both are easy to maintain, available in realistic wood looks, and made to handle everyday household wear.

The biggest difference is dent resistance. The stronger center of a rigid core plank provides more protection against dropped objects, furniture, high heels, and other impacts that can leave marks on a more flexible floor.

Rigid core can also be a good option for a less-than-perfect subfloor. Its thick planks and attached cork underlayment make it more forgiving of minor subfloor imperfections.

Armstrong Flooring rigid core products, for example, use a floating installation system, allowing the planks to lock together over the subfloor. A full-spread adhesive is not generally required, although you or your installer may choose to use one in some circumstances. Certain collection instructions may also recommend adhesive where strong sunlight could increase the risk of expansion. Always follow the installation instructions for the specific Armstrong Flooring product.

Traditional LVP remains a smart choice for many residential spaces. Rigid core may be the better fit when resistance to dents or greater forgiveness over minor subfloor imperfections is a higher priority.

Is Rigid Core Flooring Waterproof?

Rigid core flooring is 100% waterproof.* The planks will not swell, buckle, or lose their integrity when exposed to water, making rigid core a practical choice for kitchens, bathrooms, laundry rooms, basements, mudrooms, and other spaces where spills, splashes, and wet shoes are part of everyday life.

Is Rigid Core Flooring Pet Friendly?

Rigid core flooring is a great fit for homes with pets. Its strong core helps resist dents, while the durable wear layer helps protect against scratches, scuffs, and stains. Waterproof construction also comes in handy for water-bowl splashes, muddy paws, and the occasional accident.

Add easy cleaning to the list, and rigid core can take a lot of the worry out of sharing your floors with four-legged family members.

Is Rigid Core Flooring Easy to Install? Is It DIY-Friendly?

Rigid core flooring is DIY-friendly thanks to its locking installation system. The planks lock together and float over the subfloor, so adhesive is generally not required. For homeowners comfortable measuring and cutting planks, it can be a manageable DIY flooring project.

What Is HDPC® Flooring?

HDPC stands for high-density polymer core. It is an advanced type of rigid core flooring built around an ultra-dense polymer center. The technology builds on traditional rigid core by increasing the density of the core for greater dent resistance and even better stability through temperature changes. In other words, HDPC takes the durability and stability that make rigid core appealing to homeowners and pushes that performance further.

HDPC is not a completely separate flooring category or visual style. It is a higher-performance construction within the rigid core luxury vinyl plank category. Homeowners still get the waterproof surface, hardwood visuals, locking installation, and easy maintenance associated with rigid core flooring, along with a core made for more demanding conditions.

Armstrong Flooring recently introduced DLuxe Plank HDPC™, a luxury vinyl plank collection built around its proprietary HDP core technology. The collection takes the familiar benefits of rigid core flooring—waterproof performance, dent resistance, and realistic wood looks—and adds the greater stability of an ultra-dense core for spaces that may face heavier use or wider temperature changes.

Armstrong Flooring DLuxe Plank HDPC Options

DLuxe Plank HDPC™ is available in Foundation and Signature collections. Both feature our proprietary HDPC® core for exceptional dent resistance and extreme stability, resisting expansion and contraction as temperatures change. DLuxe Plank HDPC can remain stable in temperatures from 0°F to 200°F without cupping or warping, making it a strong option for spaces that experience significant temperature swings. Both collections are also 100% waterproof*, require no acclimation before installation, and feature Diamond 10® Technology, our most durable coating, which provides superior scratch resistance to keep floors looking newer longer.

What Does the Difference Mean for Homeowners?

Traditional LVP, regular rigid core, and HDPC flooring can be installed in many of the same rooms. The best choice depends on the conditions in your home and the level of performance the floor needs to deliver.

Where to Install LVP, Rigid Core, & HDPC in Your Home

Where Traditional LVP May Work Well

Traditional luxury vinyl plank can be a practical choice for bedrooms, guest rooms, home offices, dining rooms, and other temperature-controlled spaces where the floor is less likely to face frequent moisture, dropped objects, or especially heavy household activity.

It remains an attractive, easy-care flooring option with a wide range of realistic wood visuals. Depending on the product, traditional LVP may be installed with adhesive or a locking system.

Where Rigid Core Makes Sense

Rigid core flooring can be used throughout a climate-controlled home. Its waterproof construction and greater dent resistance make it especially useful in kitchens, bathrooms, laundry rooms, basements, mudrooms, family rooms, hallways, playrooms, and homes with pets or children.

It also brings the look of hardwood into moisture-prone spaces where natural wood may not be the most practical choice. Homeowners dealing with minor subfloor imperfections may appreciate the thicker planks and attached cork underlayment as well.

Where HDPC Can Make a Difference

HDPC flooring is designed for the same types of residential spaces as regular rigid core, but its ultra-dense polymer core provides greater stability and added dent resistance.

The clearest reason to choose HDPC is a room that experiences wider temperature changes. Three-season rooms, sunrooms, unheated basements, and other spaces that may become considerably warmer or cooler than the rest of the house can benefit from its added resistance to expansion and contraction.

HDPC may also be worth considering for the hardest-working spaces in an active home. An extra-busy kitchen, mudroom, entryway, laundry room, or family room may regularly face dropped objects, heavy furniture, pets, children, and near-constant activity.

Regular rigid core flooring can perform well in those same rooms. HDPC simply adds another level of strength and stability when the space is likely to face tougher conditions.

Start with the Way You Live

The strongest flooring is not automatically necessary for every room. A quiet guest bedroom and a three-season room exposed to major temperature swings do not ask the same things of a floor.

Traditional LVP can handle many everyday residential spaces. Rigid core adds greater dent resistance and can be more forgiving of minor subfloor imperfections. HDPC builds on rigid core performance with added stability through temperature changes and strength for demanding areas of the home.

The acronyms may sound technical, but the decision is personal. Choose the construction that fits the room, your household, and the way you actually live.

*The flooring material itself is waterproof. Moisture and flooding can still affect the subfloor or substrate beneath the flooring. See the applicable warranty and installation instructions for complete details.
