PM 49 – High-Performance Soundproofing Metallic Door

PM 49 is a professional-grade sounproofing metallic door engineered for spaces that demand maximum sound insulation. Designed for recording studios, cinemas, auditoriums, machine rooms, and industrial facilities, it achieves an impressive noise reduction of 52 dB. 

With a robust 85 mm structure and a complete metallic frame, PM 49 delivers uncompromising soundproofing integrity, durability, and fire safety. It combines technical precision with proven performance, offering architects and engineers a reliable solution for high-spec environments.

How It Works

PM 49 is built around a heavy central core and two absorbent chambers filled with M0 fire-rated materials, which dissipate airborne noise energy through internal damping and mass.

A double sealing profile runs around the full perimeter of the door, ensuring a complete airtight barrier, while a manual wedge-type self-opening and closing system guarantees optimal sealing pressure. The metallic frame with internal absorptive lining enhances the system’s structural stability and prevents vibration transfer.

Key Benefits

• Certified Rw = 52 dB acoustic insulation, ensuring near-complete sound isolation.
• 85 mm thick structure engineered for demanding acoustic applications.
• Double sealing system for continuous perimeter soundproofing.
• Combines mass, absorption, and airtight sealing for superior performance.
• Fire-safe materials rated M0, ensuring protection and compliance.
• 180° hinge rotation for wide, accessible openings.
• Long-lasting reliability with minimal maintenance requirements.

Installation Overview

PM 49 is supplied as a complete door set with frame, lock, hinges, and seals. The frame covers the full perimeter and can be anchored or screwed into position, depending on the wall type.

Optional features include removal of the bottom frame section in favour of a mobile threshold seal, as well as acoustic glazing, panic bars, and key locks. Installation is suitable for brick, concrete, and steel structures.
