PM 37 – Acoustic Metallic Door for Industrial Spaces

PM 37 is a precision-engineered soundproofing metallic door designed for technical rooms, machinery enclosures, and multipurpose industrial spaces. Its robust steel construction and comprehensive sealing deliver dependable sound isolation, stability, and long-term reliability in noise-sensitive environments.

How It Works

The 44 mm thick leaf combines structural density with vibration damping to limit airborne noise transmission. A tubular steel frame and steel sheets enclose a dense, highly absorbent acoustic core. 

Around the perimeter, a double sealing profile limits sound leakage, while a mechanical drop seal at the threshold maintains contact with the floor where there is no frame on the pavement side. Together, these elements create a resilient soundproofing barrier that maintains performance over time.

Key Benefits

• Reliable airborne noise control for demanding technical environments.
• Continuous perimeter sealing, plus a drop seal, for effective containment.
• Stable operation with hinges that allow precise vertical adjustment.
• Robust build quality for heavy service and frequent use.
• Ready to integrate with standard industrial and building base materials.

Installation Overview

PM 37 is supplied as a complete door set with frame, locking hardware, hinges, and sealing components. It is suitable for installation into concrete, brick, or steel structures. Optional accessories, such as acoustic vision panels, door closers, and panic bars, are available on request.
