PM 42S – Secure Soundproofing Door

PM 42S is a premium acoustic and security door that combines sound insulation, safety, and refined design in one robust structure. Designed for house entrances, offices, and private spaces, it provides exceptional protection from both noise and intrusion. With a total thickness of 80 mm and an elegant wood veneer finish, PM 42S offers the ideal balance between technical performance and aesthetic appeal.

How It Works

Built on a reinforced metallic frame, PM 42S integrates multiple high-density layers engineered for superior noise control. The door core features a heavy inner section and two sound-absorbing chambers, filled with fire-rated M0 materials, which effectively absorb and dampen airborne noise.

Around the perimeter, double acoustic seals ensure airtight closure, while a mechanical drop seal at the threshold maintains full contact with the floor to prevent leakage. The door features a 7-point locking system and four safety bolts on the hinge side, providing enhanced physical security. The result is a system that delivers Rw = 45 dB of certified sound reduction with the strength and reliability of a true security door.

Key Benefits

Installation Overview

PM 42S is supplied as a complete door set with frame, pre-frame, lock, hinges, and finishing components.
The frame is divided into two parts:

• A pre-frame, to be installed during wall construction for alignment and stability.
• The main frame, which contains the sound-absorbing material and sealing system.

Installation is compatible with brick, concrete, and reinforced walls. Once fitted, the door provides both high acoustic isolation and advanced security for residential and commercial use.
