When considering floor installations or renovation projects, the visual and design aspects are highly valued. However, the underlayment, the layer of material applied between the concrete (or existing flooring in renovation) and the final flooring, is essential for long-term floor durability.

Durability: The Key to Choosing an Underlayment

In a recent online survey conducted by Amorim Cork Composites in the American market, consumers identified durability as the primary reason for installing an underlayment.

We gathered opinions from over 300 individuals who planned to install or had recently installed new flooring in their homes. The results indicated that consumers valued the durability that underlayments offer.

Cork vs. 100% Foam: Which Offers Greater Durability?

Considering the need for durability and the variety of options on the market, why should one choose a cork underlayment over a 100% foam-based solution? To answer this, we conducted two specific tests.

Dynamic Load Test

This test simulates the pressure exerted on the floor by foot traffic, trolleys, and office chairs with casters, among others. Effective underlayment must withstand this pressure without losing its absorption characteristics.

We subjected samples of both cork and foam (each 10mm thick) to 100,000 cycles at 75 KPa pressure. The results showed cork underlayments perform significantly better than 100% foam-based solutions, maintaining their characteristics. Cork only lost 5% of its thickness, while foam recorded a loss of 55%.

Creep Test

This test determines the weight that can be placed on a given floor over a 10-year period (e.g., furniture weight). Cork demonstrated higher resistance to compressive creep due to its resilience. Cork maintains its thickness over the years, whereas foams (PU, PE, or PP) lose density and effectiveness as pressure causes cell breakage.

In summary, tests indicate that cork-based underlayments ensure long-term flooring durability and performance, translating to consumer savings by avoiding early floor replacement. Additionally, cork solutions offer prolonged comfort akin to the first day of installation.

Performance and Sustainability

Besides performance, cork-based underlayments present a more sustainable alternative compared to foam-based solutions. According to independent studies by EY consultant, Amorim's underlayments have a negative carbon balance, with carbon capture exceeding production-related emissions.

Foam Back vs Cork Back Vinyl Flooring: What's the Difference?

When installing new vinyl flooring, selecting the right type of underlayment is crucial. Foam and cork are two popular options. Let's explore their differences and determine which is better for your needs.

Understanding Underlayment

Underlayment is a layer of material placed between the floor and the vinyl, serving to protect the flooring, insulate and soundproof the room, and ease the installation process.

Foam Back Underlayment

Foam core backing, made from polyurethane, provides thermal insulation and acoustic isolation, making it a residential favorite. It's effective at stopping heat flow and has a high R-value, making it ideal for warm climates or energy-efficient buildings. It reduces noise transmission between floors and rooms.

Advantages of Foam Core Backing

• Inexpensive: Foam is more affordable than cork.
• Thermal Performance: It keeps flooring warm in winter and cool in summer.
• Acoustic Isolation: Reduces noise transmission between floors.
• Softness: Comfortable for standing or walking and protects flooring from damage.

Disadvantages of Foam Core Backing

• Less Durable: Foam may not withstand heavy foot traffic.
• Moisture Traps: Foam can absorb moisture leading to mold and mildew.
• Heavy: Foam is heavy and challenging to handle and install.
• Environmental Impact: Made from non-renewable resources and can release harmful chemicals.

Cork Back Underlayment

Cork is a natural material from the bark of cork oak trees, known for acoustic and thermal insulation. It is sustainable and biodegradable. It effectively reduces noise transmission and is a superb insulator due to its poor heat conduction and high R-value.

Advantages of Cork Backing

• Thermal Performance: Keeps flooring warm in winter and cool in summer.
• Acoustic Performance: Reduces noise transmission between floors and rooms.
• Natural Material: Biodegradable and environmentally friendly.
• Sustainably Sourced: Harvested from trees without harm.
• Easy to Install: Lightweight and user-friendly.

Disadvantages of Cork Backing

• More Expensive: Costs more than foam core insulation.
• Moisture Traps: Can absorb moisture, leading to mold and mildew.

Foam Back vs Cork Back: Which is Better?

The choice between foam and cork underlayment depends on individual needs and preferences. Foam is budget-friendly and ideal for thermal and acoustic insulation, while cork is sustainable and effective at noise reduction but pricier.
