When it comes to high-quality flue systems for commercial kitchens, Metaloterm flue systems are widely recognised as one of the leading solutions for twin wall flue system requirements & single wall flue. Known for their durability, flexibility, and performance, they are a popular choice for restaurants, industrial kitchens, and complex extraction projects across the UK.

In this guide, we’ll break down what Metaloterm is, why it’s used, and when it’s the right choice for your project.

What is a Metaloterm Flue System?

Metaloterm is a premium manufacturer of modular flue and chimney systems, designed for both commercial and industrial applications. Their systems are commonly used for:

  • Commercial kitchen extraction

  • Solid fuel appliances (wood-fired ovens, charcoal grills)

  • Heating systems and plant rooms

  • Industrial exhaust applications

The key advantage of Metaloterm systems is their modular twin wall construction, allowing for safe, efficient routing of flue gases both internally and externally.

Why Metaloterm is Widely Used in the UK

In commercial kitchen environments, flue systems must handle high temperatures, grease-laden air, and strict compliance requirements. Metaloterm systems are designed with these challenges in mind.

High Temperature Resistance

Metaloterm flues are built to withstand the demands of commercial cooking, including solid fuel applications where temperatures can be significantly higher.

Twin Wall Insulation

The insulated design helps maintain flue gas temperatures, improves performance, and ensures safety when passing through buildings or running externally.

Modular & Flexible Design

Sections can be configured to suit complex routes, making them ideal for tight spaces or challenging installations.

Long-Term Durability

Manufactured from high-grade stainless steel, Metaloterm systems are built for longevity — even in demanding environments.

Where Metaloterm Flue Systems Are Used

Metaloterm is particularly well suited to commercial kitchen installations where performance and compliance are critical.

Common applications include:

  • Restaurants and takeaways

  • Hotels and hospitality venues

  • Wood-fired pizza ovens

  • Charcoal grills and solid fuel cooking

  • Central production kitchens

  • Mixed-use or city centre developments

They are especially valuable in projects where flue routes are complex or highly visible, requiring both performance and a clean finish.

Metaloterm for Solid Fuel Kitchens

Solid fuel cooking — such as charcoal or wood-fired ovens — creates higher levels of heat, smoke, and grease.

Metaloterm systems are often specified for these environments because they:

  • Handle higher flue gas temperatures

  • Maintain strong draft performance

  • Reduce condensation and build-up within the flue

  • Provide safe clearance from combustible materials

When combined with appropriate filtration or abatement systems, they form part of a complete compliant solution.

Compliance & Safety Considerations

In the UK, commercial flue systems must meet strict standards. Metaloterm systems help support compliance by offering:

  • Certified, tested flue components

  • Safe installation through walls, ceilings, and roofs

  • Reliable performance in line with building regulations

  • Compatibility with commercial extraction systems

However, the product alone isn’t enough — correct design and installation are just as important.

The Importance of Professional Installation

Even the best flue system will underperform if it’s installed incorrectly. That’s why working with experienced commercial flue installers is essential.

A professional installation ensures:

  • Correct sizing and airflow performance

  • Safe routing through the building

  • Proper support and structural integrity

  • Compliance with fire and environmental regulations

  • Long-term reliability and reduced maintenance issues

Metaloterm vs Standard Flue Systems

While there are many flue systems available, Metaloterm stands out for:

  • Higher build quality

  • Greater flexibility for complex projects

  • Proven performance in commercial environments

  • Suitability for both standard and high-temperature applications

For projects where reliability and compliance are critical, it’s often the preferred choice.
