FZ100 Fire Safe Zone - innovative fire protection for modular construction

FZ100 Fire Safe Zone revolutionises modular construction

As modular construction becomes increasingly popular, so does the need for smart and effective fire protection solutions. This is where the FZ100 Fire Safe Zone comes in - a fire insulation panel specifically designed to save time and increase safety. At the same time, it facilitates future adaptations and changes.

"The FZ100 panel is the result of our endeavour to offer a comprehensive fire protection solution that meets the toughest requirements of modular construction," says Johan Persson, Business Development Manager at Tremco CPG Sweden. "By installing it in the factory, we can guarantee correct assembly right from the start."

 

A description of the FZ100 Fire Safe Zone

The FZ100 Fire Safe Zone is a fire insulation panel designed to protect penetrations for cables, pipes and other installations in modular buildings. Uniquely, the panel is pre-installed during production, meaning that much of the extensive fire protection work is already done when the modules arrive on site. The patented technology in the panel ensures that fire protection fulfils current requirements and standards.

 

How Nullifire Graphite eXpansion Technology (GXT) works

At the heart of the FZ100 panel is its expanding graphite, called GXT technology. When exposed to high temperatures, such as in a fire, the graphite swells and forms a thick, dense layer around the grommet. This prevents both fire and smoke from spreading further through the wall. The result is an effective, self-sealing solution that significantly increases safety.

"We have worked with the GXT technology to create a product that is both easy to install and extremely reliable in the event of an actual fire," explains Johan Persson. The expanding graphite means that there is no need to worry about leaks or cracks, even if conditions change over time.

 

Advantages of the FZ100 panel for modular construction

  • Time saving
    Because the FZ100 panel is assembled in the factory, it reduces the need for time-consuming on-site labour. The risk of incorrect assembly is also minimised, as installation takes place under controlled conditions.

  • Safety and security
    By installing the fire protection correctly from the start, a reliable solution is achieved that fulfils current fire requirements. This creates a safe environment for both contractors and
    future users of the building.

  • Flexibility
    The FZ100 is designed to be easily adapted to current and future needs. Should new cables, pipes or other penetrations be required, the panel can be easily adapted without compromising fire safety.

Do you need extra acoustic solutions?

A common concern when using fire insulation panels is how they affect acoustics. But the FZ100 panel is designed to retain the soundproofing properties of the wall. This means there is no need to add extra acoustic solutions and the number of products and operations can be minimised.


Types of penetrations that can be protected

The FZ100 is suitable for most common penetrations in modular construction, such as cables, combustible and non-combustible pipes and electrical installations. Whatever the type of penetration, you can rely on the panel to effectively prevent both fire and smoke spread.


FZ100 vs traditional fire protection products

In many cases, FZ100 can replace or complement traditional solutions such as fire seals and pipe collars. By having a comprehensive panel, you can reduce the number of individual details that need to be installed. This in turn can simplify both design and execution.

"We see great potential for FZ100 to replace several older methods," says Johan Persson. "When everything is pre-installed at the factory, you not only save time, you also increase safety and quality."


FZ100 contributes to a safer working environment

By installing the FZ100 panel at the production stage, there is less need to carry out complex fire seals in often inaccessible or high spaces on the construction site. It makes the job safer for installers and contributes to a better working environment.

"Safety is paramount in any construction project," emphasises Johan Persson. "With the FZ100 panel, many risks are eliminated. This is a great advantage, not only for the working environment but also for the overall project schedule and economy."


To summarise

The FZ100 Fire Safe Zone is an innovative solution that combines effective fire protection with easy installation options for modular construction. Thanks to the GXT technology with expanding graphite, a reliable barrier against both fire and smoke is created. The panel design saves time, increases safety and preserves the acoustic properties of the wall.

The FZ100 panel simply makes it easier to fulfil stringent fire requirements and ensure a safe construction process - right from the factory.
