Choosing the right type of underlayment is crucial when installing new vinyl flooring. Google suggests there are significant differences between foam and cork underlayments. The main factors include insulation, durability, cost, and environmental impact.

In this blog post by the Virgin Carpets and Flooring team, we’ll break down the pros and cons of foam back vs cork back vinyl flooring so you can make the best decision for your home or business.

Understanding Underlayment

When putting down vinyl flooring, it’s important to use an underlayment. This layer sits between the subfloor and the vinyl flooring, serving several crucial purposes:

1. It protects the flooring from damage.
2. It helps to insulate and soundproof the room.
3. It makes the installation process easier and more stable.

There are two main types of underlayment: foam and cork. Below, we explore the characteristics of each to help you decide which fits your needs best.

Foam Back Underlayment

Foam core backing is a popular underlayment choice for vinyl flooring, offering thermal insulation and acoustic isolation. Typically made from polyurethane, foam core comes in both high and low-density varieties and is most commonly used in residential applications due to its affordability and good thermal performance.

Foam core is effective at thermal insulation and has a high R-value, resisting heat transfer effectively. This makes it ideal for floors in warm climates or energy-efficient buildings. It also acts as a good acoustic barrier, reducing noise transmission between floors and rooms.

Foam core backing is available in two varieties: closed-cell foam and open-cell foam. Closed-cell foam is dense and impermeable to moisture, making it suitable for high moisture areas. Open-cell foam is less dense and more absorbent, fitting low-moisture environments better.

Advantages of Foam Core Backing

• Inexpensive: More budget-friendly than cork backing.
• Thermal Performance: Helps keep flooring warm in winter and cool in summer.
• Acoustic Isolation: Reduces noise transmission between floors.
• Softness: Provides comfort and protects the flooring.

Disadvantages of Foam Core Backing

• Less Durable: Doesn’t withstand foot traffic as well as cork.
• May Trap Moisture: Can lead to mold and mildew growth.
• Heavy: Difficult to handle and install.
• Environmental Impact: Made from non-renewable resources and can release harmful chemicals.

Cork Back Underlayment

Cork is a natural insulation material derived from the bark of the cork oak tree. Known for its thermal and acoustic insulating properties, cork is a well-regarded choice for flooring underlayment.

Cork is a poor conductor of heat, which makes it effective for both thermal and acoustic insulation. With a high R-value, cork is one of the best insulating materials available. It also serves as an excellent sound absorber, reducing noise transmission effectively.

Advantages of Cork Backing

• Thermal Performance: Keeps flooring warm in winter and cool in summer.
• Acoustic Performance: Excellent sound absorber.
• Natural Material: Biodegradable and environmentally friendly.
• Sustainably Sourced: Harvested without harming cork oak trees.
• Easy to Install: Lightweight and user-friendly.

Disadvantages of Cork Backing

• More Expensive: Costs more than foam core insulation.
• May Trap Moisture: Like foam, can absorb moisture, leading to mold and mildew.

Foam Back vs Cork Back: Which is Better?

So, which underlayment is better: foam or cork? The answer depends on your specific needs and preferences.

If you are cost-conscious, foam core backing is an affordable alternative. It also performs well in extreme temperature or noise conditions because of its thermal and acoustic insulation properties.

For eco-friendly and sustainable material, cork is the superior choice. Its exceptional sound absorption makes it ideal for reducing noise transmission between floors. However, the higher cost is a consideration.

Should I Use Underlayment with Attached Pad Flooring?

Is Underlayment Necessary for Attached Pad Flooring?

Flooring stores are beginning to offer more floors with an attached pad instead of traditional ones. Attached pad flooring includes a padded material directly attached to the bottom side of the flooring plank, often made of foam or cork. This feature is common in specific types of luxury vinyl flooring, like SPC, WPC, and Rigid Core Flooring. Some manufacturers now offer this for laminate, cork, bamboo, and engineered wood as well.

Benefits of an Attached Pad

Attached pads help limit noise transfer between floors, improving the acoustic performance of the flooring system. They also offer some level of moisture protection.

Despite these benefits, the misconception persists that attached pads replace the need for traditional underlayment. Skipping the underlayment may save time, but it won't yield optimal floor performance and longevity.

Why Use Underlayment with Attached Pad Flooring?

Installing premium underlayment with attached pad flooring significantly improves performance. Premium underlayment enhances acoustics more effectively than the thinner low-quality padding attached to flooring.

The most crucial reason for underlayment is moisture protection. Attached pads do not form a complete moisture barrier because the pads of adjacent planks are separated by seams. Premium underlayments, with a moisture-proof lip and tape system, close these seams and prevent moisture damage.

Do I Need a Special Type of Underlayment?

Selecting the right underlayment involves considering several factors. First, check with the flooring manufacturer to ensure the chosen underlayment supports the flooring system's warranty.

Secondly, the underlayment's thickness and density matter. Avoid thick, spongy underlayments that compress under weight, damaging the flooring’s locking mechanism. Opt for thinner, high-density underlayments that provide a strong foundation.

Acoustic performance is essential. Premium underlayments include sound-dampening technology, reducing noise from foot traffic, chairs, music, and televisions. Verify the underlayment's acoustic capabilities before making a decision.

Finally, moisture protection is vital. Choose an underlayment with a complete moisture barrier. Be cautious with product packaging, as not all underlayments offer this. Ensure your choice includes a lip and tape system to prevent moisture through seams.
