Technical Comparison: IXPE vs. EPE Underlayment
| Feature |
IXPE Underlayment |
Standard PE (EPE) Underlay |
Why it Matters |
| Manufacturing |
Irradiated Cross-linked |
Physical Foaming (Non-cross-linked) |
IXPE is much stronger |
| Cell Structure |
100% Micro-closed cell |
Large, open/semi-closed cells |
IXPE is a better vapor barrier |
| Longevity |
20+ Years (No collapse) |
2-5 Years (Flattens over time) |
EPE leads to "hollow" sounds |
| Acoustic Rating |
High (IIC 70+ dB) |
Low (IIC 50-55 dB) |
IXPE is much quieter |
| Moisture Proof |
Permanent Waterproofing |
Limited (Absorbs moisture) |
IXPE prevents subfloor mold |
| Odor/Safety |
Odorless & VOC Free |
May have chemical odors |
IXPE is safer for indoor air |
