Every second counts in the event of a fire onboard. Ships and offshore platforms are consequently designed to prevent the passage of smoke, flame, and heat.

Insulation is critical to this effort, ensuring A-class constructions comply with international fire safety standards while allowing you to:

Minimise weight
Reduce insulation thickness.
Optimise logistics.

Selecting the proper insulation for the job is not always straightforward. The first step is to decide the most important criteria for your needs. We simplify this decision-making process by grouping our fire-safe solutions into clear options for A-class constructions that ensure you stay compliant and competitive, allowing you to build your vessels with confidence.

Our experts are also always on hand to discuss your A-class insulation needs and advise on the optimal solution.

Selecting A-Class insulation

Insulation plays a critical role in ensuring an A-class construction can deliver the necessary performance, particularly when it comes to mitigating heat transfer to the unexposed side of the bulkhead or deck. However, selecting of the most appropriate insulation isn’t always a straightforward task and must consider a range of factors including:

Weight
Thickness
Installation speed
Acoustic and thermal performance
Certification

As an example:

Heavier or thicker insulation may come with higher acoustic or thermal performance but will increase weight carried with implications for energy consumption and CO₂ emissions.

Lightweight insulation products and constructions have thus been developed to provide the necessary fire protection without adding unnecessary overall ship weight: our SeaRox® range of lightweight stone wool insulation is a case in point. Other circumstances may require a thicker or heavier insulation to meet necessary acoustic or thermal insulation standards, even if this is not required from a fire safety standpoint.

In addition to these technical concerns, factors such as product range and complexity, delivery time and logistics, technical support, documentation packages, and the range of facings available from the supplier should be considered.

Five insulation options for A-class constructions

Selecting the right insulation solution for your A-class steel construction will ultimately depend on your specific needs and priorities.

What's the deal with facings?

Facings provide an attractive, protective surface that shields insulation from the elements and defends against mechanical impacts. They also counter water vapour ingress and lower weight and costs by replacing cladding in areas with limited traffic. We offer a complete range of facings for our SeaRox insulation products – from lightweight glass tissue and aluminium foil to heavier glass cloth and combinations thereof.
