Underlayment Options for Hardwood Floors
When installing hardwood floors, selecting the appropriate underlayment is crucial for performance and longevity. Underlayment serves multiple functions, including sound absorption, moisture protection, and additional insulation. Here are some common options:
- Foam Underlayment: Lightweight and easy to install, foam underlayment provides excellent sound absorption and cushioning. It is often recommended for engineered hardwood floors.
- Felt Underlayment: Made from recycled paper or fiber, felt offers superior moisture control and durability. It is typically used for solid hardwood floors and can help in leveling minor imperfections in the subfloor.
- Cork Underlayment: This eco-friendly option is highly effective in sound dampening and thermal insulation. Cork is naturally resistant to mold and mildew, making it suitable for areas with higher humidity.
- Rubber Underlayment: Extremely durable, rubber underlayment is ideal for high-traffic areas. It provides excellent sound reduction and shock absorption, making it suitable for both residential and commercial applications.
- Moisture Barrier: In areas prone to moisture, a moisture barrier underlayment is essential. This barrier prevents water vapor from seeping into the hardwood, which could lead to warping and other damage.
Factors to Consider When Choosing Underlayment
Selecting the right underlayment for hardwood floors involves several considerations. The following table summarizes key factors to keep in mind:
| Factor | Considerations |
|---|---|
| Type of Hardwood | Engineered vs. solid hardwood may require different underlayment types. |
| Subfloor Condition | Assess if the subfloor is level, dry, and clean to determine if a thicker underlayment is necessary. |
| Moisture Levels | In humid environments, choose underlayment with a moisture barrier to prevent damage. |
| Noise Reduction | Consider sound-absorbing materials if sound insulation is a priority. |
| Installation Method | Some underlayments are more compatible with specific installation types (nail-down, glue-down, or floating). |
Installation Tips for Underlayment
Proper installation of underlayment is key to the performance of hardwood flooring. Here are some essential tips:
- Roll Out the Underlayment: Ensure the underlayment is rolled out in the same direction as the hardwood planks. This alignment aids in moisture management and provides consistent support.
- Seal Seams: Use tape to seal seams between underlayment pieces to prevent moisture penetration and ensure a smoother surface.
- Trim Excess Material: After rolling out the underlayment, trim any excess around the edges of the room to prevent buckling.
- Overlap Edges: If using a moisture barrier, make sure the edges overlap to create a continuous barrier against moisture.
- Check for Flatness: Before laying down the hardwood, ensure the underlayment is flat and free from lumps or debris, which can affect the final floor surface.
Choosing the right underlayment and following proper installation techniques will contribute significantly to the durability and comfort of hardwood floors.

Essential Considerations for Underlayment in Hardwood Flooring
Dr. Emily Carter (Flooring Specialist, National Wood Flooring Association). “Choosing the right underlayment is crucial for hardwood floors. It provides sound insulation, moisture protection, and can enhance the overall comfort of the flooring. A foam or cork underlayment is often recommended for its ability to absorb sound and provide a slight cushioning effect.”
Mark Jensen (Certified Home Inspector, HomeSafe Inspections). “When installing hardwood floors, it is essential to consider the subfloor condition. A vapor barrier may be necessary, especially in areas with high humidity. This prevents moisture from damaging the hardwood, ensuring longevity and stability of the flooring.”
Susan Lee (Interior Designer, Design Innovations). “Aesthetic considerations should not be overlooked when selecting what to put under hardwood floors. The underlayment can influence the feel and sound of the floor. For instance, a thicker underlayment can create a softer feel underfoot, which is particularly beneficial in living spaces.”
Frequently Asked Questions (FAQs)
What do you put under hardwood floors for moisture protection?
A moisture barrier, typically a polyethylene sheet or specialized underlayment, is essential to prevent moisture from the subfloor affecting the hardwood. This is particularly important in basements or areas with high humidity.
Is underlayment necessary for hardwood floors?
While not always mandatory, underlayment provides cushioning, sound absorption, and moisture protection, enhancing the overall performance and comfort of hardwood floors.
What type of underlayment is best for hardwood floors?
Foam or cork underlayment is commonly recommended, as they offer sound insulation and cushioning. For engineered hardwood, a thinner underlayment may be suitable, while solid hardwood may require a thicker option.
Can you install hardwood floors directly on concrete?
Yes, but it is advisable to use a moisture barrier and an appropriate underlayment to prevent moisture issues and ensure proper installation.
How thick should the underlayment be for hardwood floors?
The thickness of the underlayment typically ranges from 1/8 inch to 1/4 inch, depending on the type of hardwood and the specific needs for sound absorption and cushioning.
What happens if you don’t use underlayment under hardwood floors?
Not using underlayment can lead to increased noise, discomfort underfoot, and potential moisture damage, which may compromise the integrity and lifespan of the hardwood flooring.
In summary, the choice of what to put under hardwood floors is crucial for ensuring the longevity and performance of the flooring. The primary options include underlayment materials such as foam, cork, and felt, each providing different benefits. Foam underlayment is popular for its affordability and sound-dampening properties, while cork offers excellent thermal insulation and moisture resistance. Felt underlayment is another option that provides cushioning and sound absorption, contributing to a more comfortable walking experience.
Additionally, it is important to consider the specific conditions of the installation area. For example, if the hardwood floors are being installed over concrete, a moisture barrier is essential to prevent water damage. In contrast, when installing over a wooden subfloor, a simpler underlayment may suffice. Understanding the subfloor type and the environment will guide homeowners in selecting the appropriate underlayment that meets their needs.
Ultimately, the right underlayment can enhance the performance of hardwood floors by improving insulation, reducing noise, and providing a stable foundation. Homeowners should weigh the pros and cons of each material and consider their specific circumstances to make an informed decision. This careful consideration will lead to a successful flooring installation that not only looks great but also stands the test of time.
