You’ve finally chosen the perfect laminate flooring for your home – it’s stylish, durable, and within your budget. Now, you’re facing the final hurdle before installation: the underlay. But a thought crosses your mind: can you double up on underlay for a more comfortable and secure floor?

This is a question many homeowners grapple with, particularly those seeking the ultimate comfort and stability for their laminate floors. The answer, however, isn’t a simple yes or no. It depends on a number of factors, including the type of underlay you’re considering, the condition of your subfloor, and the overall performance expectations for your new floor. This article delves into the world of underlay for laminate flooring, exploring the pros and cons of doubling up, and helping you make an informed decision for your project.
The Importance of Underlay for Laminate Flooring
Foundation for Sound and Comfort
Underlay serves as the foundation for laminate flooring, acting as a buffer between the subfloor and the click-lock planks. It plays a crucial role in determining the overall sound absorption, comfort, and longevity of your new floor. By adding a layer of cushioning, underlay minimizes noise transmission, enhances walking comfort, and protects the laminate from wear and tear.
Subfloor Imperfections
Subfloors are rarely perfectly smooth and level. Underlay helps bridge these imperfections, providing a stable and even surface for the laminate to rest upon. This not only prevents unevenness in the final floor but also reduces stress on the laminate planks, preventing damage from shifting or warping.

Moisture Control
While laminate flooring is relatively water-resistant, it’s not waterproof. Underlay, especially moisture-resistant types, further protects the flooring from moisture damage by creating a barrier against spills and leaks. This is particularly important in areas prone to humidity or spills, such as kitchens and bathrooms.
The Case for Doubling Underlay
Enhanced Sound Reduction
Doubling up on underlay can significantly enhance sound reduction, especially in areas where noise control is paramount. By creating a thicker layer of cushioning, you effectively muffle footfall and prevent noise from travelling between floors. This is particularly beneficial in apartments or homes with open floor plans.
Increased Comfort underfoot
For those seeking superior comfort underfoot, doubling up on underlay can make a noticeable difference. The additional layer of cushioning provides a more luxurious and forgiving surface, reducing fatigue during extended periods of standing or walking.
Improved Insulation
Certain underlay materials, such as foam, inherently provide insulation. Doubling up can create a thicker layer of insulation, enhancing thermal comfort and potentially reducing heating and cooling costs.
The Risks of Doubling Underlay
Increased Thickness and Potential Issues
Adding extra underlay can significantly increase the thickness of your flooring, potentially creating issues with doors opening and closing, furniture fitting under cabinetry, or uneven transitions between floor surfaces.
Impact on Stability
Excessive thickness can lead to a less stable floor, especially if the subfloor is not level. The added cushion can allow for more movement and bounce, affecting the overall stability of your laminate flooring.
Warranty Concerns
Most laminate flooring manufacturers have specific recommendations regarding underlay thickness. Exceeding these recommendations may void your warranty, leaving you responsible for any potential future problems.
Choosing the Right Underlay
Matching Underlay Type to Your Needs
The best way to determine whether doubling up on underlay is right for you is to consider the specific underlay materials you’re working with. Some underlay types are more prone to compressing or buckling under extra weight, while others are more resilient and designed for greater thickness.
Foam Underlay
Foam underlay is a popular choice for its affordability and sound-absorbing properties. However, it can compress over time, especially with additional weight. This makes it less ideal for doubling up, as it might lead to instability and unevenness in the floor.
Cork Underlay
Cork underlay is known for its excellent sound absorption, insulation, and natural properties. It’s more resilient than foam, making it a better option for doubling up. However, cork is generally more expensive than other underlay types.
Rubber Underlay
Rubber underlay is highly durable and offers superior noise reduction and moisture resistance. It’s a good choice for doubling up, as it tends to maintain its shape and provides a stable surface for the laminate flooring.
Underlay for Subfloor Conditions
The condition of your subfloor is another crucial factor in deciding whether to double up. If your subfloor is relatively smooth and level, doubling up might be unnecessary. However, if you have noticeable unevenness or significant subfloor imperfections, adding extra underlay might be beneficial.
Alternative Solutions for Enhanced Comfort and Sound Reduction
If you’re concerned about the risks associated with doubling up on underlay, there are alternative solutions to enhance comfort and sound reduction without compromising the stability of your floor:
Thicker Underlay
Instead of doubling up, consider using a thicker underlay that meets the recommended thickness for your laminate flooring. Several manufacturers offer thicker underlay options designed to provide superior sound reduction and comfort.
Additional Soundproofing
For enhanced soundproofing, you can install sound-absorbing materials underneath the subfloor. This is particularly effective in areas separating living spaces from bedrooms or other areas requiring sound isolation.
Can You Double Up On Underlay For Laminate Flooring
Conclusion
Doubling up on underlay for laminate flooring can enhance comfort, sound reduction, and even insulation, but it’s not always the optimal solution. You should carefully assess the type of underlay, the condition of your subfloor, the potential risks, and alternative solutions before deciding. Ultimately, the best choice depends on your specific needs, budget, and the overall goals for your flooring project. Consulting with a flooring professional can help you make an informed decision and ensure a successful installation.
