What is PET Felt Acoustic Panel? Guide for Offices, Hotels & Commercial Spaces
Learn what PET felt acoustic panels are, how to choose density and thickness, and why designers and contractors love them. Real tips, installation insights, and FAQs included.
What is PET Felt Acoustic Panel?
If you are planning an office renovation, hotel interior, or commercial space, you might have heard about PET felt acoustic panels. But what exactly are they, and why are they becoming a top choice for designers and contractors worldwide?
I remember a project in Milan: the design changed the wall shape two times, and the contractor was worried about dust and frayed edges. With PET felt panels, we could adjust onsite without reordering, and the installation went smoothly. That experience taught me why these panels are more than decoration—they solve real-world problems.
Material Overview
PET felt panels are made from recycled polyester fibers (PET = polyethylene terephthalate). They are compressed and heat-bonded into dense, lightweight boards.
Key points:
- Eco-friendly, made from recycled materials
- Lightweight: 1.5~2.3 kg/m², depending on thickness and density
- Resistant to fraying, stains, and moisture
- Available in up to 58 colors
The felted surface absorbs sound naturally, reducing echo and noise, while providing a soft touch and modern aesthetic.
Acoustic Performance
PET felt panels are chosen for sound absorption.
- NRC range: 0.85–0.95
- Thickness options: 5mm, 9mm, 12mm, 18mm，24mm or customize
Examples:
- 12mm → offices, meeting rooms
- 24mm → auditoriums, hotels, high-ceiling spaces
Tip from experience: even premium panels perform poorly if installation is uneven or substrate isn’t flat.
Density and Application
Common densities:
- 1500 gsm – decorative walls, light acoustic use
- 2000 gsm – standard office or retail spaces
- 2400 gsm – high-traffic areas, deep acoustic demand
Higher density panels provide:
- Cleaner edges when cutting
- Better structural stability
- More solid feel on installation
For example, in a boutique hotel, using 2400 gsm panels prevented edge fraying during onsite trimming.
Installation Advantages
PET felt panels are lightweight and easy to install:
- Wall or cabinet mounting can be done by one person
- CNC cutting allows custom shapes, curves, or cut-outs
- Faster and safer than wood slats or mineral fiber panels
Story: A designer changed a geometric pattern the night before installation. With PET felt, the contractor re-cut panels onsite. No delays.
Durability and Maintenance
- Stain-resistant; clean with a damp cloth
- Stable, no warping
- Resistant to minor impacts
Commonly used in offices, schools, airports, retail stores, and hotels.
Reliable Production and Lead Time
- Production: 5–15 days
- Shipping to Europe, Australia, Middle East
Predictable supply helps reduce project delays and scheduling headaches.
One client come to us for PET U-shape baffles urgently, asked us to produce the 300pcs of U-shape baffles in 5days and send to his forwarder to catch the earliest plane, we confirm the CAD and pre-production sample in 1day, and arranged the current production schedule, finished the cutting and packing in 3days, finally give his forwarder 2extra days to arrange shipment smoothly.
PET Felt vs Traditional Acoustic Materials
Feature | PET Felt | Fabric Wrapped | Wood Slat | Mineral Fiber |
|---|---|---|---|---|
Density | 1500 / 2000 / 2400 gsm | Limited | Heavy | Fixed |
NRC | 0.85–0.95 | Medium | Medium | Medium |
Weight | 1.5~2.3 kg/m² | Medium | Heavy | Medium |
Installation | 1 person | 2+ people | Framing required | Fragile |
Cutting | Clean | Fray risk | Good | Dusty |
Conclusion
PET felt acoustic panels are eco-friendly, lightweight, durable, and versatile. They solve real-world problems: acoustic absorption, easy installation, low maintenance, and fast lead times.
If you are a designer, contractor, or wholesaler, consider requesting samples, color charts, or technical data sheets. Correct density, thickness, and installation details often decide whether a project finishes on time and within budget.
