When it comes to a laminate flooring installation, most homeowners focus on the appearance, durability, and cost of the flooring itself. But one key component often overlooked is the underlayment. The type of underlayment you choose can significantly affect how your floor sounds when walked on. At Acuario Flooring in Alpharetta, GA, we know that great flooring doesn’t just look good—it should feel and sound good too.
Let’s explore how underlayment choices impact the acoustics of laminate flooring and what options are best suited for your space.
Why underlayment matters in laminate flooring installation
Laminate flooring is a floating floor system, which means it is not glued or nailed down to the subfloor. Instead, it "floats" above the subfloor with the help of a locking mechanism between planks. This creates a small air gap that can result in hollow or clicking noises if not properly addressed with a quality underlayment.
Underlayment acts as a buffer between the subfloor and the laminate planks, providing support, stability, and—most importantly in this case—sound insulation. During a laminate flooring installation, choosing the right underlayment can make a noticeable difference in how quiet and comfortable your floors feel underfoot.
Types of underlayment and their acoustic properties
Different types of underlayment materials offer various levels of sound control. Here are the most common options:
Foam underlayment
Standard foam underlayment is one of the most affordable and widely used options for laminate flooring. While it provides basic cushioning and minor sound reduction, it may not be the best choice for sound-sensitive areas like bedrooms or multi-level homes.
Felt underlayment
Felt underlayment is a step up from foam in terms of acoustic performance. It’s denser and absorbs more sound, making it ideal for rooms where foot traffic noise is a concern. Felt also offers good thermal insulation, which is a bonus in cooler months.
Rubber underlayment
Rubber is one of the most effective materials for reducing impact sound and vibrations. It is often used in commercial settings or in multi-family homes where noise control is critical. Though it is more expensive than foam or felt, its superior acoustic performance can be worth the investment.
Cork underlayment
Cork is a natural material that offers both thermal and acoustic benefits. It’s antimicrobial, eco-friendly, and provides excellent sound absorption. Cork underlayment is especially good at muffling footfall noise and reducing transmission between floors in multi-story homes.
Sound rating systems to consider
When selecting underlayment for a laminate flooring installation, it's useful to understand the sound rating systems:
-
Impact Insulation Class (IIC): Measures how well a material reduces impact sounds, like footsteps.
-
Sound Transmission Class (STC): Measures how well a material reduces airborne sounds, like voices or music.
Higher IIC and STC ratings indicate better sound performance. At Acuario Flooring, we can help you compare underlayments based on these metrics to choose the best option for your needs.
Choosing the right underlayment for your space
If you live in a multi-level home or have high-traffic areas like hallways and kitchens, investing in higher-performance underlayment can drastically reduce noise and improve overall comfort. For ground-level rooms or basements, moisture resistance may also be a deciding factor, which can influence both acoustics and longevity.
It’s also important to consider your subfloor type—concrete and plywood react differently to sound, so the right underlayment can help balance that.
