Fire-Resistant Sandwich Panel: A Specialized Solution for High-Temperature Industrial Applications
Fire-resistant sandwich panels are used for specific industrial purposes such as hot rooms above 70°C and baking ovens.
They can withstand temperatures up to 2000°C, and while offering aesthetic appeal and fast construction, they feature unique characteristics that effectively meet customer requirements.
What is a Fire-Resistant Sandwich Panel?
A fire-resistant sandwich panel is a building material designed to prevent the spread of fire due to its special structure (as shown in the panel image).
These panels consist of three main layers:
• Two outer layers (usually made of heat-resistant metal)
• A core of flame-retardant insulating material such as rock wool or fire-resistant polyurethane
This combination not only ensures safety but also delivers excellent thermal insulation, making it a smart choice for environments at risk of fire.
Applications of Fire-Resistant Sandwich Panels
As a highly effective fireproof insulation solution, fire-resistant sandwich panels are used in sensitive buildings and industries.
Thanks to their unique structure, they prevent flame propagation and enhance safety against fire hazards.
Choosing this product guarantees the security of your space and minimizes potential damage.
Key applications include:
• Industrial and commercial structures: such as workshops, factories, and warehouses
• Public buildings and hospitals: to protect lives in emergencies
• Refineries and power plants: due to high flame resistance
• Cold storage facilities and sensitive environments: where temperature control and fire safety are crucial
Fire-resistant sandwich panels, thanks to their unique features, not only improve safety but also enhance the durability of buildings.
What Are Fire-Resistant Sandwich Panels Made Of?
Fire-resistant sandwich panels are composed of the following materials:
1. Outer layers: Made of heat-resistant aluminum or galvanized steel.
2. Core: Typically rock wool or flame-retardant polyurethane, which acts as both thermal and fire insulation.
3. Surface coating: For additional protection against moisture and chemicals.
This multilayer structure effectively prevents heat transfer and ensures structural safety.
Advantages and Disadvantages of Rock Wool Insulation in Sandwich Panels
Advantages:
• More affordable and comprehensive insulation compared to foams
• Low thermal conductivity (though higher than foam)
• Excellent resistance to direct heat — completely fireproof and suitable for various kilns
• Relatively good adhesion to the metal sheets
Disadvantages:
• Its fibrous and porous structure weakens molecular bonds, making it prone to separation from the metal sheets
• Due to its porosity, water easily penetrates it
• When exposed to moisture, its thermal conductivity increases, reducing effectiveness
• Shorter lifespan compared to foam insulation
