L FELT – PET Acoustic Panel

L FELT is part of DECIBEL’s collection of PET acoustic panels made from recyclable felt materials. The panels are designed to improve the acoustic comfort of a room while adding clean and functional design elements. With its elongated “L” shape, L FELT allows more flexible layouts that adapt to both large and small spaces.

Made from polyester felt with 65% recycled content, the panels absorb mid- and high-frequency sounds, reducing echo and improving speech clarity. They are lightweight, durable, and easy to integrate into new or existing interiors, making them a suitable solution for offices, schools, and residential buildings.

How It Works

The soft PET felt structure absorbs airborne sound waves that reflect off hard surfaces such as walls and ceilings. Installed in repeating or offset patterns, the L-shaped geometry helps break up reflections and balance sound throughout the room. This improves the acoustic comfort and overall sound quality in shared spaces.

Acoustic and Environmental Performance

• Made from 100% polyester (65% recycled) material
• Provides effective sound absorption (NRC up to 1.00 depending on configuration)
• Fire classification: B–s1, d0 (EN 13501-1)
• Fully recyclable and made using low-emission, sustainable processes

Design and Application Options

L FELT panels can be customised in size, thickness, shape, and colour, making them suitable for different types of interiors. They can be used as:

• Wall-mounted acoustic panels
• Ceiling baffles or hanging clouds
• Desk dividers and free-standing partitions
• Full-surface acoustic wall coverings

Available in standard 500 × 750 mm dimensions (custom options available) and 6 / 9 / 12 / 18 / 24 mm thicknesses, L FELT can be adapted to the design and acoustic needs of any space. Panels are available in a full range of RAL colours.
