Marine Insulation

Fire-rated, thermal, and mechanical insulation for marine vessels — including mechanical and exhaust piping systems, complete jacketing, and class-rated fire separation assemblies.

Work Environments

Marine insulation work is performed onboard vessels and in shipyard environments where access, safety, and timing are tightly controlled.
Typical settings include:
Engine rooms and machinery spaces
Piping systems and tanks
Vessel accommodation and service areas
Dry-dock and shipyard work zones
Mechanical and exhaust piping runs (engine-room and service routes)
Exhaust trunks, risers, and high-temperature lines
Work is planned to integrate with vessel schedules and other trades.

Typical Engagement Scenarios
Vessels are in dry dock or port
Systems are being upgraded or repaired
Heat protection or energy efficiency is required
Work must align with inspection schedules
Space and access are limited
Delays would impact sailing schedules
Mechanical or exhaust piping systems are being installed or upgraded
Fire separation ratings must be maintained across penetrations or service zones
System Scope

Mechanical and exhaust piping insulation for temperature control and personnel protection.


Appropriate jacketing to protect insulation from moisture, abrasion, and service conditions.


Thermal insulation to reduce heat loss and stabilize system performance.


Class-rated fire separation insulation where required to maintain rated boundaries and safe passage.

Fire-rated insulation systems, including A-60 class divisions and related assemblies, are provided where required to meet marine fire protection standards, along with broader marine insulation applications across vessel systems.

Pre-Arrival Planning

Confirm access, sequencing, permits, and vessel safety requirements before mobilization.

System Walkdown & Measurement

Verify routes, clearances, penetrations, and maintenance access around mechanical and exhaust piping.

Material Selection & Preparation

Select insulation and jacketing suited to temperature range, vibration, moisture, and service conditions.

Installation in Confined Spaces

Install thermal and mechanical insulation with clean terminations and protected edges.

Jacketing & Protection

Fit and seal jacketing to protect insulation from moisture, abrasion, and operational wear.

Fire Separation & Close-Out

Complete class-rated fire separation scopes where required, then verify, clean, and document for turnover.

Marine insulation work is performed in accordance with applicable safety standards and Transport Canada expectations.
Coordination with shipyard safety programs and vessel personnel is essential throughout the work.
