Frequently Asked Questions
How do acoustic panels work?
Acoustic panels absorb sound waves to reduce reverberation, preventing sound from bouncing off hard surfaces like walls and ceilings. This helps in managing noise levels, improving speech intelligibility, and providing a more comfortable acoustic environment.
What is NRC (Noise Reduction Coefficient)?
NRC measures the sound absorption properties of a material. An NRC rating of 0.0 means no absorption, while a rating of 1.0 indicates total sound absorption. Most acoustic panels, including PET panels, have NRC ratings ranging from 0.3 to 1.0, depending on material and thickness.
What is NRC (Noise Reduction Coefficient)?
What sizes are available for Non-Woven PET panels?
Panels are available in standard sizes of 2440mm x 1220mm, with custom sizes available on request.
What thicknesses are available?
Thicknesses range from 5mm to 150mm, depending on the acoustic performance and application. What densities are available for PET panels? Panels are available with densities ranging from 1500 GSM to 4000 GSM, offering different levels of impact resistance and sound absorption.

What are the benefits of using PET acoustic panels?
What are the benefits of using PET acoustic panels?
Not Soundproofing: PET panels absorb sound but do not block it from entering or leaving a space. UniVicoustic offers products that can do more than just sound absorption e.g. Uni-VicStrip that also has reflection and absorption.
Durability: PET panels are durable but can be punctured by sharp objects.
Environmental Conditions: PET panels can absorb and release moisture but are not affected by typical indoor conditions.
UniVicoustic PET panels do not fade under any normal indoor environment.

How do PET panels handle UV resistance?
- Recycled polyester fiber-made acoustic panels generally have “Moderate UV resistance”
- Polyester fibers, including recycled variants, are inherently more UV-resistant than natural fibers like wool or cotton, meaning they are less prone to fading or degrading when exposed to sunlight. However, prolonged or direct exposure to UV rays can still cause some discoloration or weakening over time.
- For indoor use with limited sunlight exposure, UV resistance is typically not a major concern.
- However, in spaces with significant natural light, opting for panels with additional UV protection may extend their lifespan and appearance. To improve UV resistance, manufacturers often add UV stabilizers or coatings to the panels, especially for outdoor or high-exposure applications. These treatments can help protect the panels from fading, yellowing, or becoming brittle due to UV exposure.
Do PET panels absorb odors?
- Polyester fiber-made acoustic panels are generally resistant to absorbing odours. Polyester, being a synthetic material, is less porous than natural fibers like wool or cotton, which makes it less prone to trapping and retaining odours. This property makes polyester acoustic panels a good choice for environments where odour control is important, such as restaurants, kitchens, or public spaces.
- However, if the panels are exposed to strong, persistent odour over a long period, they might absorb some smell, though this is typically minimal compared to other materials.
- Additionally, polyester panels can often be cleaned or aired out if odour become a concern
What type of sound frequencies do PET panels absorb best?
- PET panels are particularly effective at absorbing mid to high-frequency sounds (500 Hz to 4000 Hz), making them ideal for reducing speech-related noise. With proper installation, they can also absorb low-frequency sounds.
How does the air gap affect acoustic performance?
- Adding an air gap behind the panel enhances sound absorption, particularly for low-frequency sounds.
- With no air gap: NRC values range from 0.45 to 0.70.
- With a 50mm air gap: NRC values can reach 0.80 to 0.95.
Can PET panels be used in conjunction with insulation to improve sound absorption?
- Yes, combining Non-Woven PET panels with insulation (such as mineral wool) can further improve sound absorption, especially for low and mid-range frequencies.
How does PET compare to other acoustic materials?
- PET panels are more durable, eco-friendly, and moisture-resistant compared to foam or fiberglass materials. They also offer more design flexibility.
Are PET acoustic panels fire-resistant?
- Yes, PET panels typically comply with fire safety regulations and have fire ratings suitable for public and commercial spaces.
What is VMT Technology?
- VMT (Virtual Material Technology) enhances the aesthetic appeal and acoustic performance of PET panels, offering flexibility in design and sound absorption.
What CNC and laser operations are possible on PET?
- PET panels can undergo CNC and laser cutting, which allows for intricate designs and custom modifications without affecting performance.
How consistent is the color of PET acoustic panels?
- Base Color of Recycled Fibres: Since the base color of recycled polyester is typically not pure white, the final color of PET panels may vary slightly.
- Solution: To achieve better color consistency, manufacturers use color masterbatch or pigment additives, which is a more appropriate technology for recycled PET compared to dyeing the fibers.
Challenges with Recycled Polyester.
- Variability in Raw Materials: Recycled PET fibers come from diverse sources (such as plastic bottles), which may result in slight differences in color or transparency. This can affect the final appearance of the panels.
Are PET panels resistant to microorganisms?
- Synthetic Nature: Polyester fibers are synthetic and do not serve as a food source for most microorganisms like bacteria or fungi. Unlike natural fibers like wool or cotton, PET does not easily degrade and is less prone to microbial attack.
- Antimicrobial Treatments: Some manufacturers may apply antimicrobial treatments or coatings to further enhance the resistance of PET panels to microorganisms.
How do PET panels handle insect resistance?
- Non-Organic Material: As polyester fibers are non-organic, insects like termites, ants, or moths, which typically feed on natural materials, are not attracted to PET. This makes PET panels resistant to insect bites and infestations.
- Non-Organic Material: As polyester fibers are non-organic, insects like termites, ants, or moths, which typically feed on natural materials, are not attracted to PET. This makes PET panels resistant to insect bites and infestations.
What is a coffered ceiling?
- A coffered ceiling features a series of recessed panels in square, rectangular, or octagonal shapes, typically used for aesthetic and acoustic purposes.
Do you make custom-sized panels?
What are the largest panels you can make?
- Yes, we can manufacture panels in almost any size or shape, up to 9’x4’. For panels larger than 48”x24”, shipping may require LTL (less-than-truckload) freight services.
Are these panels stackable?
- Yes, the acoustic panels are stackable. The acoustic core holds pins and tacks without damage, and the fabric used often has self-healing properties. However, excessive paper coverage on the panels may reduce sound absorption efficiency.
Is there a recommended spacing between panels?
- No specific spacing is required as long as the minimum recommended acoustic coverage is achieved.
How do I install acoustic panels?
Acoustic panels can be installed using:
Tip: Always ensure the mounting surface is clean and dry before installation.
What is the recommended panel thickness for optimal sound absorption?
Panel thickness typically ranges from 10mm to 50mm. Thicker panels are more effective
at absorbing low-frequency sound, while thinner panels are ideal for higher frequencies.
What are the typical installation methods for PET panels?
Common installation methods include:
- Commercial spaces: Wall-mounted panels with adhesive or frame systems.
- Public spaces: Suspended baffles or ceiling clouds for open areas.
- Auditoriums and convention centers: Large, customized panels with higher NRC ratings and additional insulation for superior sound control.
Can Non-Woven PET panels be installed outdoors?
