Calm Workspaces in Motion: Acoustic Upgrade for an Office Building in Hamburg, Germany

2026-02-25

During the refurbishment of a multi-tenant office building in Hamburg, Germany, the owner encountered a familiar problem in modern workplaces — sound traveled freely across corridors and meeting areas.

Conversations overlapped and hard finishes amplified daily activity.

Decorative coverings improved appearance but weakened acoustic performance, while softer materials lacked durability. The design team therefore looked for a stable fiber-reinforced material that could act as both a protective surface and an acoustic facilitator.

After consultation, GRECHO proposed integrating Fiberglass Veil as the facing layer of the interior acoustic wall panels. The controlled permeability of the Fiberglass Surfacing Veils allowed sound waves to pass into the absorptive core rather than reflect back into the space.

In circulation zones, Glass Faced Ceiling Veils were applied to maintain consistent acoustic behavior between walls and ceilings. The engineered structure of the Fiberglass Veil reduced reverberation while remaining dimensionally stable under daily temperature and humidity changes.

Once installed, the working atmosphere improved noticeably. Background noise softened, speech became clearer during meetings, and employees reported less fatigue after long working hours.

Maintenance teams also found the panels easy to clean and resistant to surface damage from routine use. The material met required fire resistance standards for commercial buildings, and the durable fiber-reinforced material surface maintained its integrity without compromising acoustic performance over time.

For the building owner, the project demonstrated that acoustic comfort does not rely solely on thick insulation layers.

A carefully engineered Fiberglass Veil surface can function simultaneously as a finish, protection layer, and acoustic facilitator — improving productivity while preserving the architectural appearance of the workspace.
