Understanding the importance of a solid foundation for your laminate flooring is crucial for its longevity and performance. The underlayment isn’t just there for aesthetics—it plays a critical role in how your floors feel, sound, and even how long they last. So, let’s explore the complexities of using cardboard in this crucial role.
Why Is Underlayment Important for Laminate Flooring?
Laminate flooring, while durable, relies on a good underlayment for optimal performance. Here’s why:
- Sound Absorption: Laminate flooring can be quite noisy, especially when walking on it. A good underlayment helps absorb sound, creating a quieter and more comfortable environment.
- Moisture Barrier: Laminate flooring is susceptible to moisture damage. An underlayment can act as a barrier, protecting your floor from potential water damage caused by spills or leaks.
- Leveling and Cushioning: Many subfloors are not perfectly level. A good underlayment can help smooth out imperfections and provide a more even surface for your laminate flooring, which can also help reduce the chances of squeaking.
- Installation Stability: The underlayment serves as a stable base for your laminate flooring, preventing movement and ensuring that your new floors stay secure.
The Limitations of Using Cardboard as Underlayment
While cardboard is readily available, it’s crucial to understand that it’s often not the best choice as an underlayment for laminate flooring. Here’s why:
- Inconsistent Surface: Cardboard is not a uniform material and can have uneven surfaces. This can lead to a less-than-perfect finish for your laminate flooring.
- Compression: Cardboard is prone to compression under foot traffic. Over time, it can become compacted, and this can lead to the laminate flooring becoming unstable and potentially even sagging.
- Moisture Sensitivity: Cardboard is highly susceptible to moisture damage. If spills occur or even if humidity levels are high, cardboard can easily absorb moisture, leading to warping, buckling, and ultimately, damage to your laminate flooring.
- Pest Issues: Cardboard can be a breeding ground for pests such as termites and cockroaches. As these pests can degrade wood, they pose a significant threat to your laminate flooring and even the structural integrity of your home.
Alternatives to Cardboard
Instead of using cardboard, consider these common and more suitable alternatives for your underlayment:
- Foam Underlayment: This is a popular and effective choice. It provides excellent sound absorption, cushioning, and moisture resistance. Foam underlayment is also affordable and easy to install.
- Cork Underlayment: Cork is known for its sound-absorbing qualities, natural moisture resistance, and resilience. It can be a bit pricier than foam, but if you prioritize a natural and eco-friendly option, cork is a great choice.
- Fiberboard Underlayment: Fiberboard is made from wood fibers and offers good moisture resistance. It is thicker than foam but is still relatively easy to install.

Choosing the Right Underlayment
Selecting the right underlayment is crucial. Here are factors to consider:
- Your Budget: Prices of underlayment vary significantly. Options like foam are generally affordable, whereas cork can be more expensive.
- The Thickness and Density: Thicker and denser underlayments offer more sound absorption and cushioning. Consider the thickness based on your subfloor’s condition and desired level of cushioning.
- Moisture Resistance: Opt for underlayment that is moisture-resistant, especially if you live in a humid climate or have potential water leaks.
- Installation Ease: Some underlayments are easier to install than others. Consider your DIY skills and the complexity of your project.
Installation of Underlayment
Before installing your laminate flooring, ensure your subfloor is cleaned and prepared. Then, carefully measure and cut the underlayment to fit your space. When installing, overlap seams by at least 6 inches to prevent gaps.
Can You Use Cardboard Under Laminate Flooring
The Bottom Line: Don’t Use Cardboard!
Using cardboard as an underlayment for laminate flooring is generally not recommended. While it might seem like a convenient and cheap option, the drawbacks outweigh the benefits. It can lead to uneven surfaces, compression, moisture damage, and even pest infestations. Invest in a quality underlayment, such as foam, cork, or fiberboard, to ensure your laminate flooring is properly supported and lasts for years to come.
Remember, choosing the right underlayment can significantly impact the performance and lifespan of your laminate flooring. So, it’s worth investing in a high-quality and appropriate option for a truly successful and long-lasting floor installation.
