This article explains which installation method fits your project budget, space condition, and performance expectation.
How to Install PET Felt Acoustic Panels for Better Acoustic Results
Why Installation Matters More Than People Think
Same material.
Different installation.
Very different acoustic result.
Many performance complaints come from incorrect mounting.
1. Direct Glue Installation
Simple and cost-effective.
Best for:
- Small rooms
- Decorative applications
Limitation:
- Reduced mid-frequency absorption
2. Air Gap Installation (Recommended)
Adding 20–50mm cavity behind the panel:
- Improves mid-frequency absorption
- Increases effective absorption coefficient
- Reduces reverberation more efficiently
This method is strongly recommended for offices.
For understanding why this improves absorption, refer to our article explaining sound absorption vs soundproofing.
3. Suspended Baffles or Ceiling Systems
Best for:
- High ceiling spaces
- Large reverberant rooms
Benefits:
- Dual-side absorption
- Better surface coverage efficiency
Common Installation Mistakes
- Uneven substrate
- No expansion gap
- Overuse of air nails
- Ignoring reflective surfaces like glass
Proper installation can improve acoustic result more than increasing thickness.
