Types of Underlayment Materials

When it comes to installing flooring, choosing the right underlayment material is crucial. Underlayment serves as a protective layer between the subfloor and the flooring material, providing stability, insulation, and soundproofing. There are several types of underlayment materials available in the market, each with its own benefits and drawbacks.

Felt Underlayment

Felt underlayment, also known as roofing felt, is one of the oldest and most common types of underlayment materials. It is made from recycled wood fibers that are compressed and saturated with asphalt. Felt underlayment is affordable and easy to install, making it a popular choice for many homeowners. It provides moderate moisture protection and helps smooth out minor imperfections in the subfloor. However, it does not provide much sound insulation and is not recommended for use in high-moisture areas.

Cork Underlayment

Cork underlayment is a natural and eco-friendly option that is gaining popularity in recent years. It is made from the bark of cork oak trees and is known for its excellent soundproofing properties. Cork underlayment also provides good insulation and is resistant to mold and mildew. Additionally, it is soft underfoot, making it comfortable to walk on. However, cork underlayment can be relatively expensive compared to other materials, and it may not be suitable for areas with heavy foot traffic or high moisture levels.

Rubber Underlayment

Rubber underlayment is a versatile material that offers both sound insulation and moisture protection. It is made from recycled rubber, such as old tires, which makes it an eco-friendly choice. Rubber underlayment is highly durable and can withstand heavy loads and foot traffic without deteriorating. It also provides excellent shock absorption, making it ideal for areas where impact resistance is important, such as gyms or playrooms. However, rubber underlayment can be more expensive than other options, and it may have a distinct odor during installation.

Foam Underlayment

Foam underlayment, also known as foam padding, is a popular choice for laminate flooring and floating floors. It is lightweight, affordable, and easy to install. Foam underlayment provides good insulation and soundproofing properties, helping to reduce noise transmission between floors. It also offers some moisture protection, although it is not completely waterproof. However, foam underlayment may compress over time, especially in high-traffic areas, and it may not be suitable for heavy loads or areas with moisture issues.

Fiberglass Underlayment

Fiberglass underlayment, also known as fiberglass mat, is a highly durable and moisture-resistant option. It is made from woven fiberglass fibers that are coated with asphalt. Fiberglass underlayment provides excellent moisture protection, making it suitable for areas with high humidity or potential water exposure, such as basements and bathrooms. It also offers good sound insulation and can help reduce noise transmission. However, fiberglass underlayment can be more expensive than other materials, and it may require special tools and expertise for installation.


Choosing the right underlayment material is essential to ensure the longevity and performance of your flooring. Each type of underlayment material has its own advantages and disadvantages, and the best choice depends on your specific needs and budget. Felt underlayment is a cost-effective option, while cork underlayment provides excellent soundproofing. Rubber underlayment offers durability and shock absorption, while foam underlayment is lightweight and easy to install. Fiberglass underlayment provides superior moisture protection. Consider the characteristics of each material and consult with a flooring professional to determine which underlayment material is best suited for your project.
