Helios
A light, flexible partition with powerful acoustic performance.
The Helios Tensed Division is a sculptural acoustic room divider designed for modern spaces that crave openness without sacrificing acoustic comfort. Using a system of tensioned PET felt panels, held in place by discrete cables and steel framing, Helios offers a refined, semi-transparent spatial separation, without the heaviness of walls or fixed partitions.
Ideal for open-plan offices, lounges, lobbies, or creative studios, Helios defines zones while softening sound. Its large circular cut-outs and architectural proportions (up to 3600 mm high) create visual interest while maintaining light flow and spatial connection.
Crafted from ARCHISONIC® Felt, made with 60% post-consumer recycled PET, the panels are available in 36 color options, with high acoustic performance. Offering up to 62 Sabins of absorption in real-world conditions.
The system includes pre-engineered mounting hardware and a steel frame in RAL 9005 black, with a clean, minimalist profile that complements any interior palette. With a 10-year warranty, high durability, and sustainable material credentials, Helios Tensed Division is as reliable as it is elegant.
