GLL™ – Geometry Live Line Acoustic Panel

GLL™ acoustic panels are distinctive triangular 3D panels that combine sculptural form with exceptional sound absorption. The GLL™ series is a statement of acoustic design innovation, offering both functional performance and visual artistry.

Created to improve sound quality in offices, conference halls, schools, studios, restaurants, and hospitality interiors, these acoustic panels transform reverberant environments into calm, acoustically balanced spaces. Each surface interacts beautifully with natural or artificial light, turning functional acoustic treatment into a design feature.

How It Works

Every GLL™ panel is made from technical polyurethane foam with a density of 18 – 30 kg/m³, wrapped in an acoustic textile that enhances absorption efficiency. The panels are shaped in five distinct physical geometries, each with a different inclination that allows designers to create endless visual compositions.

For individual installations, the GLL panels measure 60 × 60 × 84 cm, with a profile thickness ranging from 3 cm to 5 cm. The combination of porous foam and fabric facing effectively absorbs mid- and high-frequency sound waves, reducing echo and improving speech clarity.

Key Benefits

• Significantly reduces reverberation and echo, creating comfortable acoustic environments.
• Distinctive triangular 3D geometry transforms walls into sculptural surfaces.
• Available as modular panels or as individual GLL-3D units for flexible design layouts.
• Made from recycled polyurethane foam and wrapped in premium acoustic fabric.
• Offered in 22 colour options to complement diverse interior styles.
• Lightweight, durable, and easy to maintain with a damp cloth or mild detergent.

Installation Overview

GLL™ panels are designed for straightforward wall or ceiling installation using polyurethane montage adhesive, double-sided tape, or a mounting system for semi-permanent applications. No specialist tools are required. The fabric wrapped panels can be arranged in geometric clusters or full-surface compositions to achieve both acoustic and visual harmony.
