11/29/20234 min read

Introduction

Foil glass wool blankets are a popular choice for insulation in various applications due to their excellent thermal properties and versatility. Composed of glass fibers and a layer of reflective aluminum foil, these blankets offer effective heat insulation, sound absorption, and fire resistance. In this article, we will explore the specifications, technical parameters, product advantages, application scenarios, and address common questions regarding foil glass wool blankets.

Specifications of Foil Glass Wool Blankets

Foil glass wool blankets are available in various specifications to suit different insulation requirements. These blankets typically come in rolls or batts, with standard widths ranging from 600mm to 1200mm. The thickness can vary from 25mm to 100mm, allowing for customization based on specific needs. Additionally, the density of foil glass wool blankets ranges from 10kg/m³ to 48kg/m³, providing options for different levels of insulation.

Technical Parameters of Foil Glass Wool Blankets

Foil glass wool blankets possess impressive technical parameters that contribute to their effectiveness as insulation material. The thermal conductivity of these blankets typically ranges from 0.032 W/m·K to 0.040 W/m·K, ensuring efficient heat insulation. Furthermore, their noise reduction coefficient (NRC) can reach up to 1.0, making them ideal for soundproofing applications. With a fire resistance rating of A1, foil glass wool blankets are non-combustible and do not contribute to the spread of flames.

Product Advantages of Foil Glass Wool Blankets

Foil glass wool blankets offer several advantages that make them a preferred choice for insulation:

Excellent Thermal Insulation: The combination of glass fibers and the reflective aluminum foil layer creates an effective barrier against heat transfer, helping to maintain comfortable indoor temperatures.
Sound Absorption: Foil glass wool blankets have excellent sound absorption properties, making them suitable for environments where noise reduction is desired, such as recording studios, theaters, and offices.
Fire Resistance: With a fire resistance rating of A1, foil glass wool blankets provide a high level of safety. They do not ignite, release toxic gases, or contribute to the spread of flames.
Moisture Resistance: The aluminum foil layer acts as a vapor barrier, preventing the penetration of moisture and protecting the insulation material from damage.
Easy Installation: Foil glass wool blankets are lightweight and flexible, making them easy to handle and install. They can be cut to fit specific areas and are compatible with various construction materials.

Application Scenarios of Foil Glass Wool Blankets

Foil glass wool blankets find extensive use in a wide range of application scenarios, including:

Residential Buildings: Foil glass wool blankets are commonly used in residential buildings for roof insulation, wall insulation, and floor insulation. They help to maintain a comfortable indoor environment and reduce energy consumption.
Commercial Buildings: Offices, hotels, shopping malls, and other commercial buildings benefit from the thermal and acoustic insulation provided by foil glass wool blankets. They contribute to energy efficiency and create a more comfortable working or shopping environment.
Industrial Facilities: Foil glass wool blankets are utilized in industrial settings to insulate pipes, ducts, boilers, and other equipment. They help to prevent heat loss, reduce noise, and enhance safety.
Transportation: Foil glass wool blankets are also used in the automotive and aerospace industries to insulate vehicle interiors, engine compartments, and aircraft cabins. They help to regulate temperature and reduce noise levels.

Does Aluminum Foil Help with Heat Insulation?

Aluminum foil plays a crucial role in enhancing the heat insulation properties of glass wool blankets. The reflective nature of aluminum allows it to reflect radiant heat, preventing it from penetrating through the insulation material. This helps to maintain a more stable indoor temperature and reduces the need for excessive heating or cooling, resulting in energy savings.

Will Glass Wool Insulation Catch Fire?

Glass wool insulation, including foil glass wool blankets, is non-combustible and does not catch fire. It has a high fire resistance rating of A1, which means it does not contribute to the spread of flames or release toxic gases when exposed to fire. This makes it a safe and reliable choice for insulation in various settings.

Why Should Glass Wool Be Soaked in Water?

Glass wool is often recommended to be soaked in water before installation. This process is known as water soaking or water immersion. There are several reasons for this:

Dust Reduction: Glass wool can sometimes release small particles or dust during handling and installation. Soaking the material in water helps to minimize this issue by weighing down the fibers and reducing the release of dust.
Enhanced Flexibility: Water soaking makes the glass wool fibers more flexible and easier to handle. This allows for better conformity to irregular surfaces and improves the overall installation process.
Improved Acoustic Performance: Soaking glass wool in water can enhance its sound absorption capabilities, making it more effective in reducing noise levels.
Safer Handling: Wetting the glass wool reduces the risk of fibers becoming airborne, making the installation process safer for workers and occupants.

Conclusion

Foil glass wool blankets offer an effective solution for heat insulation, sound absorption, and fire resistance. With their excellent thermal properties, ease of installation, and versatility, they find widespread use in residential, commercial, and industrial applications. The inclusion of an aluminum foil layer further enhances their heat insulation capabilities. Glass wool insulation, including foil glass wool blankets, is non-combustible and safe to use. Soaking glass wool in water before installation provides various benefits, including reduced dust release and improved flexibility. Consider foil glass wool blankets as a reliable and efficient insulation choice for your next project.
