Why PET Polyester Acoustic Panels Are Becoming the Go-To Choice for Modern Interiors
Across schools, offices, and public buildings, acoustic performance is no longer optional. As spaces become more open and multi-purpose, controlling noise has become a practical necessity rather than a design extra.
At the same time, specifiers are paying closer attention to durability, safety, and environmental impact. This has led to a noticeable shift toward PET polyester acoustic panels as a reliable, long-term solution.
The changing requirements of modern spaces
Today’s interiors are expected to do more. A single room may be used for teaching, meetings, collaboration, or community events. Hard surfaces such as concrete, glass, and plasterboard are common — and acoustically unforgiving.
In these environments, traditional soft finishes alone are no longer enough. Designers are looking for acoustic treatments that:
- Perform consistently
- Are safe and robust
- Integrate easily into different layouts
- Meet environmental expectations
PET polyester panels respond well to these requirements.
What makes PET polyester panels different
PET acoustic panels are manufactured from recycled polyester fibres, pressed into dense, sound-absorbing boards. Unlike some traditional acoustic products, they do not rely on fabric wraps or fragile finishes.
In practical terms, PET panels:
- Absorb sound effectively to reduce echo
- Maintain their shape over time
- Do not fray, sag, or delaminate
- Are suitable for high-use environments
This makes them particularly well suited to education, commercial offices, corridors, and public spaces.
A practical approach to sustainability
Sustainability claims are common in the building industry, but PET panels offer a clear and measurable benefit. They are typically made using a high percentage of recycled material and are designed for long service life.
For specifiers, this means:
- Reduced reliance on virgin materials
- Panels that can be reused or relocated
- Fewer replacements over the life of the building
Rather than being a short-term solution, PET acoustic panels align with long-term building strategies.
Design flexibility without complexity
Another reason PET panels are gaining ground is their design flexibility. They can be used as:
- Wall panels
- Ceiling panels
- Hanging baffles or screens
- Pinboards and functional surfaces
Available in a wide colour range and multiple thicknesses, PET panels allow designers to control sound without complicating construction or maintenance.
Why Decrasound fits this shift
Decrasound PET Polyester Acoustic Panels are designed with these real-world requirements in mind. They provide reliable sound absorption, are suitable for demanding environments, and support responsible material choices.
Rather than chasing short-term trends, Decrasound focuses on products that are practical, durable, and proven — qualities that remain important as buildings evolve.

Frequently Asked Questions
What are PET polyester acoustic panels?
PET polyester acoustic panels are sound-absorbing panels made from compressed polyester fibres (often with a high recycled content). They are designed to reduce echo and improve speech clarity in rooms with hard surfaces.
Where are PET acoustic panels most commonly used?
PET panels are commonly used in classrooms, offices, meeting rooms, libraries, corridors, and multipurpose spaces — anywhere echo and background noise make communication harder.
Do PET panels work better on walls or ceilings?
Both can work well. Wall panels help control reflections at speaking height, while ceiling panels and baffles are effective in open-plan spaces and rooms with higher ceilings. The best approach depends on the room layout and finishes.
How do I know how many panels I need?
The required coverage depends on room size, ceiling height, and how many hard surfaces you have (glass, plasterboard, concrete, vinyl flooring, etc.). A simple room assessment will determine the right quantity and placement.
Are PET polyester acoustic panels durable enough for schools and high-traffic areas?
Yes. PET panels are well suited to busy environments because they are robust, hold their shape, and don’t rely on a fabric wrap that can sag or fray over time.
