Fireproof 25mm Thick PET Acoustic Panel 100% Polyester Fiber

Acoustic Panels Factory Soundproof Wall Sound Proof Fireproof 25mm Thick Pet Acoustic Panel Polyester Acoustical Panel

 
- Improves the energy efficiency of the building
- Reduces transmission of exterior sound to the interior of the building
- Absorbs reverberating sounds within the building
- Provides thermal efficiency, helping to keep heat inside the building in the winter and outside in summer

 
Advantages:
1. We only use high quality raw fiber material;
2. Considering of using sustainable material, we use 50% to 60% of prevous post-consume recycled PET bottle-flake;
3. It's a totally healthy material that's touchable and recyclable;

• Acoustic absorption is usually defined in terms of an absorption coefficient(usually denoted by the Greek letter alpha,,
• defined as the ratio of absorbed to incident sound energy from a single interaction between a sound wave and a certain material.
• Absorption coefficients range from 0 to 1 and vary with frequency,
• means that the material absorbs no sound and reflects all sound energy incident on it.
• means that the material absorbs all sound energy incident on it and reflects none.
• Absorption coefficients of 0 and 1 are ideal values that do not exist in reality because all materials reflect and absorb some sound.
• In general, materials having absorption coefficients less than 0.15 are considered to be reflective and those having absorption coefficients greater than 0.4 are considered to be absorptive.As you can see our Testing report show that our products have a very good performance in a large range of application.

Applications: Stadium ,auditorium, multifunction room ,studio and any other places where seek for high acoustic requirement
