How to Increase Fire Safety with ETFE and Polycarbonate Materials in Architectural Projects

October 18th, 2024 1:39 pm

Fire safety is a critical consideration in architectural design, but making the right choice can be daunting sometimes. With the increasing use of modern materials like ETFE (Ethylene Tetrafluoroethylene) and polycarbonate in construction, it’s essential to understand how these materials contribute to fire prevention and safety.

As a leading provider across the UK, ARC Structures has extensive experience in the sector and in this article, we will explore different materials and their effectiveness in enhancing fire safety in both commercial and residential projects.

 

Why Material Choice Matters for Fire Safety

Different materials possess distinct characteristics, so selecting the right ones is paramount to ensure fire safety in any architectural project.

By understanding the fire-resistant qualities of each material and making informed choices, you can design spaces that are not only visually appealing and functional but also secure for everyone who uses them.

Ahead, we will discuss the ways our products and materials impact your projects fire safety, with a focus on:

  • ETFE roofs
  • Polycarbonate canopies
  • Tensile fabric structures

 

How Fire Resistant Are Polycarbonate Roofs?

Polycarbonate is a popular choice for roofing, particularly in commercial projects that require durability and safety. This thermoplastic material is renowned for its impact resistance and transparency, but its fire-resistant properties are equally noteworthy.

Polycarbonate is rated as Class B for fire resistance under the European standard EN 13501-1. This rating indicates that polycarbonate has limited contribution to fire and does not significantly promote flame spread. When exposed to high temperatures, polycarbonate tends to soften and melt rather than ignite, which helps to prevent the spread of fire. In addition, its low smoke emission characteristics make it a safer option in case of fire, reducing the risk of inhalation hazards.

For commercial projects, such as covered walkways, atriums, and shopping centres, polycarbonate roofs offer a blend of aesthetic appeal and fire safety. They provide a durable, weather-resistant solution that can withstand the rigors of commercial use while also meeting fire safety requirements.

ARC Structures specialises in the installation of polycarbonate roofing, ensuring that every project meets the highest standards of safety and performance. Here is one of our case studies:

Covered walkway at King George Hospital in London

The walkway, made with a clear polycarbonate roof and a galvanised steel frame, was intended to create an outdoor-like experience while providing weather protection. This modern and practical structure enhances the hospital’s functionality by ensuring a dry, airy passage for staff and visitors between the buildings.

How Fire Resistant Are ETFE Roofs?

ETFE, a fluorine-based plastic, has gained popularity in recent years, particularly for use in large-scale commercial projects. Its lightweight nature and high transparency make it an attractive alternative to traditional glass, especially in structures like stadiums, airports, and greenhouses. But how does it fare when it comes to fire safety?

ETFE is considered self-extinguishing, meaning that it will not sustain a flame if the source of ignition is removed. This material has an ignition temperature of around 500°C (932°F), making it highly resistant to catching fire. Moreover, ETFE does not release toxic fumes when exposed to fire, which is a critical safety feature in large public spaces where occupant safety is paramount.

In terms of fire classification, ETFE is rated as B1 under the German DIN 4102 standard, which is comparable to Class B in the European standard. This rating highlights its effectiveness in contributing to fire safety, especially in large-scale commercial projects.

How Fire Resistant Are Tensile Structures?

Tensile fabric structures are a distinctive architectural feature used in a variety of settings, from commercial spaces like outdoor canopies and pavilions to residential garden covers. These structures are constructed using steel or wire frames, over which fabric is stretched and anchored. While they offer unique aesthetic and functional benefits, it is important to consider their fire-resistant properties.

The fabrics used in tensile structures are generally treated with fire-retardant coatings, and many are rated to meet specific fire safety standards. For example, some tensile fabrics are classified as Class B under the European fire rating system. In the event of a fire, these fabrics are designed to melt away rather than ignite, reducing the risk of spreading flames. Although generally safe, it’s important to verify fabric materials and ensure fire regulation compliance before starting a new project, as not all tensile fabrics share the same characteristics.

At ARC Structures, we provide comprehensive project management services, guiding our clients through the material selection process to ensure that their tensile structures meet all necessary safety standards.
