Introduction
When it comes to flooring, most of the attention goes to the visible surface — hardwood, laminate, or vinyl. But what lies beneath can be just as important. Flooring underlayment plays a crucial role in soundproofing, comfort, and structural longevity. At Oakel City, we've recently introduced IXPE 3mm underlayer along with detailed IIC and STC test reports to help our customers make informed decisions.
This guide will break down everything you need to know about acoustic ratings, test standards, and why IXPE 3mm is a game-changer in underlayment solutions.
What Is IXPE Underlayment?
Understanding IXPE Material in Flooring
IXPE stands for Irradiated Cross-Linked Polyethylene, a high-performance foam that’s become a preferred material in modern flooring underlayment. It is known for its resilience, closed-cell structure, and superior sound-dampening qualities. Unlike traditional underlays, IXPE does not absorb moisture and resists mold and mildew, making it ideal for both residential and commercial environments.
Benefits of IXPE 3mm as an Underlayer
- Exceptional sound absorption (as proven by STC & IIC tests)
- High thermal insulation for improved energy efficiency
- Anti-microbial and moisture-resistant properties
- Enhanced comfort and footfall cushioning
- Long-lasting performance without flattening over time
Acoustic Performance in Flooring
Why Soundproofing Matters in Residential & Commercial Spaces
Sound control is essential in multi-story homes, apartment buildings, offices, and retail environments. Proper underlayment minimizes noise transmission through floors, leading to quieter, more peaceful interiors — a key feature in real estate and tenant satisfaction.
Key Terms: What Are IIC and STC Ratings?
IIC (Impact Insulation Class) and STC (Sound Transmission Class) are standardized acoustic ratings that evaluate how well a flooring system reduces noise. IIC focuses on impact sounds like footsteps, while STC evaluates airborne sounds like voices or music. The higher the rating, the better the soundproofing performance.
IIC (Impact Insulation Class) Test Explained
What Is IIC and What Does It Measure?
IIC measures the ability of a floor system to absorb impact sounds — such as walking, dropping objects, or furniture movement. It is especially important in multi-level structures where noise transmission between floors is a concern. An IIC rating of 50+ is considered good, while 60+ is excellent for residential use.
IXPE 3mm IIC Test Report Highlights
According to Oakel City's official IIC test report, the IXPE 3mm underlayment achieved outstanding performance. Here are some highlights:
- IIC Rating: 72 (tested over 6” concrete slab with no suspended ceiling)
- Test Standard: ASTM E492-09
- Performance Summary: Significantly reduces footfall and impact noise
STC (Sound Transmission Class) Test Explained
What Is STC and How Is It Measured?
STC measures how well a floor blocks airborne noise like speech, TVs, or music. It’s a crucial metric for bedrooms, apartments, and offices where privacy is important. Higher STC ratings reflect better sound isolation.
IXPE 3mm STC Test Report Highlights
Our STC test report shows impressive results for IXPE 3mm:
- STC Rating: 66 (tested over 6” concrete slab)
- Test Standard: ASTM E90-09
- Performance Summary: Blocks airborne noise efficiently for greater privacy
Comparative Acoustic Benefits of IXPE 3mm
IIC vs. STC: Understanding the Difference
While both ratings measure sound control, they address different types of noise. IXPE 3mm performs well in both categories, making it a dual-purpose acoustic solution. Its balance between IIC and STC ratings ensures comprehensive soundproofing across various environments.
How IXPE Performs Compared to Other Underlayments
Compared to traditional EVA or cork underlays, IXPE offers:
- Higher IIC & STC ratings
- Better moisture resistance
- Longer lifespan
- Superior resilience under pressure
Enhancing Flooring Comfort and Durability
Thermal Insulation Properties of IXPE
Beyond acoustics, IXPE underlayments provide a thermal barrier, improving energy efficiency. It helps maintain room temperature and reduces cold transfer from subfloors, enhancing comfort especially in colder climates.
Added Cushioning and Surface Protection
With its cushioning effect, IXPE reduces foot fatigue and protects flooring from subfloor irregularities. It prevents minor surface imperfections from telegraphing through the flooring, ensuring a smooth, long-lasting finish.
Compatibility with Different Flooring Types
- Engineered Hardwood: IXPE provides moisture protection and cushioning for floating installations.
- Laminate Flooring: Ideal pairing due to its noise reduction and thermal insulation.
- Luxury Vinyl Plank (LVP): Enhances soundproofing and comfort, especially in high-traffic areas.
Installation Best Practices
Laying IXPE 3mm Underlayment: Step-by-Step Guide
- Ensure subfloor is clean, dry, and level
- Unroll IXPE underlayment with foam side facing up
- Align edge to wall, leaving a small expansion gap
- Tape seams with moisture-resistant tape
- Install flooring directly over underlayment
Mistakes to Avoid During Installation
- Do not overlap seams
- Do not install over wet or uneven subfloors
- Avoid puncturing the underlayment with staples or nails
