The answer, as with many things in the world of home improvement, is not so simple. Laying laminate flooring is a project that’s best tackled with careful planning and consideration. Choosing the right underlay is crucial for achieving that perfect, long-lasting finish, and knowing whether or not to use two layers is a question many DIYers ask themselves. In this comprehensive guide, we’ll delve into the ins and outs of using multiple layers of underlay, breaking down the benefits, drawbacks, and ultimately helping you determine if it’s the right choice for your unique flooring project.
Understanding the Purpose of Underlay
Before we get into the debate of single vs. double layers, it’s essential to understand the fundamental role of underlay in laminate flooring. Underlay is a cushioning material installed directly beneath the laminate planks, acting as a hidden layer of support and protection. It’s not simply an afterthought, but a vital component that contributes significantly to the overall success of your flooring project.
Here’s a closer look at the key functions of underlay:
- Sound Dampening: Think of it as a soundproof barrier. Underlay absorbs impact noise, reducing the amount of footfall and other sounds that travel through your floor. This is especially important in multi-level homes where noise can easily carry between floors.
- Subfloor Leveling: No subfloor is perfectly flat. Underlay helps create a consistent, even surface, minimizing any imperfections that could cause unevenness or instability in your laminate floor.
- Moisture Protection: While laminate is known for its water resistance, it’s not entirely impervious to moisture. Underlay acts as a barrier to minimize the risk of water damage, protecting your flooring from spills and everyday wear and tear.
- Comfort and Cushioning: Underlay adds a layer of comfort to your laminate flooring. It reduces the “hardness” of the floor, creating a more comfortable walking surface, especially for your feet and joints.
- Insulation: Some types of underlay, often referred to as “foam underlay,” can provide a slight level of insulation. This can help improve energy efficiency, especially in colder climates.
The Double Underlay Debate: Weighing the Pros and Cons
Now, let’s address the main question: when it comes to underlay, is more always better? While using two layers might seem like a way to enhance the benefits we just discussed, there are both pros and cons to consider.
The Case for Double Underlay:
- Enhanced Noise Reduction: Doubling up on underlay can significantly reduce noise levels, especially if you’re dealing with a particularly noisy subfloor or live in a multi-story home where minimizing sound transfer is crucial.
- Increased Comfort: Two layers create a more cushioned and comfortable walking surface, improving the overall feeling of your floor.
- Improved Subfloor Leveling: If your subfloor has substantial imperfections, using two layers of underlay can create a more even and consistent surface.
The Drawbacks of Double Underlay:
- Increased Thickness: Doubling up on underlay will inevitably increase the overall thickness of your floor. This could cause problems with doors, sliding appliances, or in spaces with limited clearance.
- Potential for Sagging: Too much underlay can lead to sagging or instability in your laminate floor. Make sure you use an underlay that’s specifically designed for double layering, as some underlays will become too compressed and lose their effectiveness.
- Added Cost: Of course, using two layers of underlay will naturally increase your project costs.
How to Decide: The Right Approach for Your Project
So, how do you decide if using two layers of underlay is the right choice for your project? Here’s a clear decision-making guide to help:
- Assess Your Subfloor: If you have a subfloor with significant imperfections or if you are installing the laminate over concrete, using two layers of underlay might be beneficial. However, if you have a relatively flat and stable subfloor, a single layer might be sufficient.
- Consider Noise Levels: Do you want maximum noise reduction? If you have a noisy subfloor or are concerned about noise traveling between floors, two layers could provide better sound dampening.
- Check for Clearance: Measure the height of your doors and any areas where appliances might slide. If you’re working with a limited headroom, two layers might not be feasible.
- Consult a Professional: If you’re unsure about whether or not to use two layers of underlay, consult a flooring professional. They can assess your specific situation and recommend the best approach for your project.

Expert Tips for Success:
- Choose the Right Underlay: Not all underlays are created equal. Choose an underlay specifically designed for laminate flooring and that’s compatible with double layering. Consult with a flooring expert for recommendations.
- Proper Installation is Key: Even with the best underlay, improper installation can lead to problems. Make sure to follow the manufacturer’s instructions carefully and consider seeking professional help if you’re unsure about any aspect of the installation process.
- Don’t Forget the Acoustical Pad: An acoustical pad can be another helpful layer beneath your underlay for extra noise reduction. However, make sure that the combined thickness of the acoustical pad and the underlay doesn’t exceed your clearance requirements.

Conclusion:
Choosing whether or not to use two layers of underlay is a personal decision based on your specific needs and the particularities of your project. By carefully considering factors like subfloor condition, noise levels, clearance, and your budget, you can make an informed decision. Remember, the goal is to create a beautiful and long-lasting laminate floor that you can enjoy for years to come. And don’t hesitate to consult with a flooring professional for expert guidance and advice. Your flooring will thank you!
