B-15 Class Sound Reduction Single Leaf Fireproof Door

B-15 Class Sound Reduction Single Leaf Fireproof Door

Product Introduction:

The B-15 Class Sound Reduction Single Leaf Fireproof Door is a high-performance marine interior door engineered to meet two critical requirements for modern vessel accommodation: B-15 fire protection and superior acoustic insulation. Designed for crew cabins, passenger staterooms, and offshore living quarters, this door effectively contains fire while significantly reducing noise transmission between compartments, enhancing crew comfort and passenger privacy.

Product parameters:

Key Features:

*B-15 Fire Rating – Certified to prevent flame passage for 15 minutes and limit temperature rise on the unexposed side in accordance with IMO FTP Code Part 3, suitable for B‑class bulkhead installations.

*Enhanced Sound Reduction – Engineered with a high-density acoustic insulation core and precision perimeter seals to achieve significant sound transmission loss (typically STC 30–35 or Rw 30–35 dB), reducing noise from corridors, machinery, and adjacent cabins.

*Single Leaf Configuration – Compact and space-efficient, ideally suited for standard cabin entrances, stateroom access points, and corridor bulkheads.

*Acoustic Perimeter Seals – Features multi-fin rubber or silicone gaskets around the entire door frame (head, jambs, and bottom) that compress upon closing to create an airtight acoustic barrier. An automatic drop seal or sweep seal at the bottom eliminates sound leakage paths.

*Heavy-Duty Construction – Fabricated with a steel skin and a specialized multi-layer core combining non-combustible mineral fibre for fire protection and high-density acoustic material for sound dampening.

*Self-Closing Mechanism – Equipped with an automatic closing device to ensure the door closes securely in the event of fire or emergency, complying with SOLAS Chapter II‑2 requirements.

*Durable Finish – Finished with marine-grade paint, PVC laminate, or decorative veneer options to match interior cabin aesthetics while resisting wear, humidity, and cleaning agents.

Reliable Hardware – Stainless steel hinges, latch, and handle designed for frequent daily use, with acoustic optimization to minimize sound transmission through hardware gaps.

Typical Applications:

*Crew cabins on cargo ships, tankers, and container vessels.

*Passenger staterooms on ferries, cruise ships, and expedition vessels.

*Offshore platform accommodation modules.

*Naval vessel officer and crew quarters.

*Hospital and medical bays requiring quiet environments.

*Areas adjacent to noisy machinery spaces or busy corridors.

Why Choose the Sound Reduction Version?

Standard B-15 fire doors provide fire safety but often lack adequate acoustic performance, allowing corridor noise, conversations, and machinery sounds to disturb cabin occupants. The B-15 Class Sound Reduction Single Leaf Fireproof Door solves this problem by:

*Reducing noise pollution – Quieter cabins improve crew rest, passenger satisfaction, and overall well‑being.

*Maintaining fire safety – Full B‑15 certification with no compromise on fire integrity.

*Enhancing privacy – Sound containment for confidential conversations in medical or officer areas.

*Meeting modern standards – Aligns with increasing owner demands for acoustic comfort in marine accommodations.

For shipowners, marine architects, and outfitters who prioritize both fire safety and acoustic comfort, this sound‑reducing B‑15 door delivers the optimal balance.
