FS4

Fireproof skirt

The FS4 Fireproof Skirt is a protective side cover made of flame-resistant materials to protect the tires and underbody of the fire truck from the convective and radiant heat of the flame.

Its performance has been validated in both laboratory and real-world working conditions, ensuring reliable protection in high-temperature environments.

Faldón ignífugo

Designed for

Protect the truck’s tires and underbody from ignition by convective heat or direct contact with the flame, preventing the combustion of these elements, which would, on the one hand, render the vehicle unable to escape the risk zone once the flame front has passed and, on the other, generate persistent combustion associated with a large amount of gases harmful to humans.

Protection against direct fire and thermal radiation

Provides protection against convective and radiant heat for the tires and underbody of the vehicle.

Product Features

Special multi-layer fabric

The FS4's multi-layer aluminized fabric provides exceptional insulation against heat and thermal radiation, delaying the transmission of flame energy to the tire and underbody of the truck. In addition, its Kevlar stitching gives it high mechanical strength, increasing its reliability.

Quick installation

Thanks to the carabiners integrated into the skirt, installation is very quick and can be done by a single person.

Carrying bag

Store the FS4 fire skirt conveniently and safely with its carrying bag.

Advantages of using this product

The FS4 fire-resistant skirt increases the vehicle’s chances of survival in the event of a fire entrapment, allowing it to move to a safe area once the flame front has passed. Furthermore, by covering the entire underbody of the vehicle, it prevents convective currents generated by fire. These generate a very high-temperature air current that is projected beneath the vehicle, accelerating its combustion and endangering people taking shelter behind it.

Superior Protection

It offers effective protection against heat and fire and against high-temperature convective currents.

Speed ​​of deployment

Thanks to the integrated carabiners it can be deployed in seconds.

Preservation of escape routes

Helps increase the chances of escape to a safer area once the flame front has passed.

Includes the following components

Fireproof side skirt

Carabiners and vehicle fixing rings

Fireproof skirt

What Is a Fireproof Skirt?

A fireproof skirt is a thermal protection system designed to shield the underside of emergency vehicles, machinery and mobile units exposed to extreme heat, radiant energy and indirect flame contact. The lower section of a vehicle is one of its most vulnerable areas, as it allows heat, embers and flames to penetrate and damage critical components, jeopardizing both mobility and operational safety.

Why a Fireproof Skirt Is Essential in Wildfire and Industrial Fire Operations

In extreme fire environments, the underside of a vehicle can suffer:

  • Infiltration of radiant heat

  • Exposure to burning embers

  • Direct lateral flames

  • Damage to cables, hoses, tires and fuel lines

  • Secondary fires igniting beneath the vehicle

A fireproof skirt acts as a thermal barrier that blocks heat, protects sensitive components and ensures that the vehicle remains operational even in the harshest fire scenarios.

Key Features of the ISK Fireproof Skirt

The fireproof skirt developed by ISK Fire Survival is a key component of the Integral Safety Kit (ISK) and is engineered to withstand severe wildfire, industrial and structural fire conditions. Its main features include:

  • High-resistance multilayer fireproof fabric, capable of enduring intense radiant heat

  • Reflective outer layer that deflects a significant portion of thermal radiation

  • Internal thermal insulation, reducing the temperature beneath the vehicle

  • Rapid-attachment system, allowing installation within seconds

  • Universal adaptability, compatible with a wide range of vehicle types and sizes

Its combination of durability, light weight and resilience ensures reliable performance in prolonged operations.

How a Fireproof Skirt Works in an Emergency

The fireproof skirt is installed around the lower perimeter of the vehicle, creating a “thermal shield wall” that serves as a protective barrier. Its purpose is to:

  1. Block heat and flames from entering the underside of the vehicle

  2. Reduce thermal transfer to mechanical and electrical components

  3. Protect tires, hoses, wiring and fuel-related parts

  4. Prevent secondary fires caused by embers or radiant heat

  5. Maintain maneuverability in active fire zones

This protection is crucial when a vehicle must operate near a fire front, remain stationary in heated terrain or support teams in entrapment situations.

Primary Applications of a Fireproof Skirt

The ISK fireproof skirt is indispensable for:

  • Wildland firefighting vehicles

  • Initial attack units

  • Industrial emergency response vehicles

  • Civil protection units

  • Heavy machinery operating near fire zones

  • Any emergency fleet exposed to extreme thermal environments

Any vehicle working close to fire fronts or high-heat environments benefits significantly from this protective system.
