When planning your hardwood floor installation in Kernersville, NC, choosing the right underlayment is just as important as selecting the material itself. The underlayment acts as a foundation beneath your hardwood, improving stability, comfort, and even sound insulation. 

It also helps protect your flooring from moisture, which is especially important in areas with varying humidity levels. So, if you’re wondering which material to use, this guide will help you understand your options and choose the perfect underlayment for your space.

What is best to put under a hardwood floor?

Underlayment is a thin layer of material placed below hardwood flooring. It may seem like a minor detail, but it can make a big difference in how the final result feels, looks, and lasts. A proper underlayment absorbs sound, evens out minor imperfections, and prevents squeaks or shifting. In some cases, it can even help with insulation—keeping your home quieter and more energy efficient.

The best underlayment depends on your specific needs, materials that will go over, and the room’s environment. For most homes, foam or cork underlayment provides an excellent balance of comfort and affordability. In high-traffic or noise-sensitive areas, rubber or felt underlayment offers better sound insulation and stability. And for rooms where moisture is a concern, always opt for an underlayment with a built-in vapor barrier. Here are 5 choices for your space:

1. Foam underlayment

Foam underlayment is one of the most popular and affordable options for wooden floors. It provides a soft cushion that makes floors more comfortable underfoot and helps reduce noise. Many foam products also come with a built-in moisture barrier, making them suitable for rooms above ground level. However, foam isn’t ideal for high-moisture areas like basements, as it may not provide enough protection against humidity.

2. Cork underlayment

Cork is a natural, eco-friendly choice that offers excellent sound absorption and cushioning. It’s also resistant to mold, mildew, and bacteria, making it ideal for allergy-conscious homeowners. Cork underlayment works well in both floating and glue-down installations, though it’s most commonly used under engineered hardwood.

3. Rubber underlayment

Rubber underlayment provides superior sound insulation and durability. It’s denser than foam or cork, offering great stability and long-lasting support. Rubber also resists mold, mildew, and moisture, which makes it a solid choice for areas that may experience some humidity. While it’s typically more expensive, it delivers premium results in both comfort and longevity.

4. Felt underlayment

Felt underlayment, made from recycled fibers, is a great option for homeowners who want both comfort and environmental sustainability. It’s thicker than foam and cork, providing a warm, cushioned feel underfoot. Felt is also excellent at absorbing sound and offering slight thermal insulation, keeping your floors quieter and more comfortable year-round.

5. Combination (Foam + Film) underlayment

For homeowners who want the best of both worlds, a foam-and-film combination underlayment offers cushioning, sound reduction, and moisture protection. The foam provides softness and noise control, while the attached film acts as a vapor barrier, preventing moisture from damaging your hardwood. This type is often used in floor installations for added protection and peace of mind.
