1.Building insulation
Roof and wall insulation: Aluminum-faced glass wool can be used for roof and wall insulation to reduce heat loss and improve the energy efficiency of the building. The aluminum foil layer can reflect heat radiation and enhance the insulation effect.
Pipe insulation: The use of aluminum-faced glass wool on heating, cooling and hot water pipes in buildings helps to reduce heat loss or heat gain and ensure the efficiency and stability of the piping system.
2. Industrial equipment insulation
High-temperature equipment insulation: the use of aluminum-faced glass wool on high-temperature equipment such as industrial boilers, storage tanks, and drying equipment can effectively reduce heat loss and save energy.
Cold storage equipment insulation: cold storage, freezers, and other low-temperature equipment with the use of aluminum-faced glass wool can prevent the entry of external heat to maintain the stability of the low-temperature environment.
3. Acoustic applications
Acoustic walls and panels: aluminum glass wool can be used to make soundproof walls and panels, widely used in movie theaters, conference rooms, recording studios and other places that need a good acoustic environment. The porous structure of glass wool effectively absorbs sound waves, while the aluminum foil layer further blocks the spread of noise.
Mechanical equipment sound insulation: used in generator rooms, mechanical equipment rooms, and other noisy environments to improve the working environment by reducing the spread of noise.
4. Fire prevention applications
Fire doors and firewalls: Aluminum-faced glass wool has good fireproof performance and can be used to make fire doors and firewalls to enhance the fire safety of buildings.
Fireproof partition: using aluminum-faced glass wool in cable trench, pipe wells and other parts that need fireproof isolation can effectively stop the spread of fire.
5. Ships and Vehicles
Ship heat insulation and sound insulation: used in the cabin heat insulation and sound insulation of ships to ensure the comfort and safety of the environment on board.
Vehicle thermal and acoustic insulation: the use of aluminum glass wool in cars, trains, and other means of transport can effectively reduce the noise inside the car, improve ride comfort, and improve the efficiency of the air conditioning system.
6. HVAC (heating, ventilation and air conditioning) systems
Duct insulation: Aluminum-faced glass wool is commonly used in air conditioning and ventilation systems for duct insulation to prevent condensation and reduce energy loss.
Equipment insulation: HVAC system equipment, such as air handling units, heat exchangers, etc., also often use aluminum-faced glass wool insulation to improve system efficiency.
1. Excellent thermal insulation performance: glass wool itself has a very low thermal conductivity, can effectively isolate the heat transfer.
2. Moisture-proof and humidity-proof: the aluminum foil layer can prevent water vapor from entering the glass wool, maintaining the thermal insulation performance and service life of the material.
3. fire safety: glass wool and aluminum foil have good fire performance and can provide some protection in the fire.
4. Strong durability: aluminum glass wool is corrosion-resistant, not easy to age, and can be used for a long time in a variety of environments.

5. Lightweight and easy to install: the material is lightweight, easy to cut and install, and reduces the construction difficulty and time.
In short, aluminum glass wool is widely used in construction, industry, transportation, HVAC, and other fields because of its superior performance; it is an efficient, multi-functional thermal insulation material material.
Fiberglass insulation has been the undisputed standard in the construction industry since . But in , a competitor of the faced fiberglass batt appeared: Aluminium Foil Fibreglass Insulation Blanket, a heat-reflecting fiberglass fabric.
Although glass fibers have low cost and good thermal insulation performance, the stimulation of the human body has also become an unavoidable problem.
Unlike glass fiber wool, aluminum foil insulation materials, such as aluminum foil fiberglass fabrics, often appear in sheet form. Their strong metal resistance makes them easy to wrap or veneer on pipes or walls. Next, we will explain the differences between aluminum foil insulation and glass fiber insulation and their characteristics.
There are three ways of heat transfer: heat conduction, heat radiation, and heat convection.
Perhaps before this, you have noticed that the product you purchased has a parameter such as the R-value, which represents the amount of heat your insulation material conducts per inch. The primary conduction mode of heat: thermal radiation, is not within the range measured by the R-value.
Thermal radiation refers to the temperature of an object radiating electromagnetic waves. Thermal radiation often accounts for 75% of all heat losses, while aluminum foil insulation materials can block 97% of thermal radiation.
Although glass fiber and other insulating materials have good protection ability in heat convection and heat conduction, they are powerless against heat radiation. Aluminum foil insulation made of heat-reflecting aluminum is the best choice for thermal radiation insulation.
Fiberglass Insulation
After many years of use, various countries have formulated corresponding standards for glass fiber fabrics.
Most are (E-glass) alkali-free glass fiber insulation materials. Pure glass fiber is still highly irritating to the human body, and if the thread is inhaled during use, it will cause lung damage. In addition, glass fiber is useless for heat radiation and high-humidity environments.
However, glass fiber still has some advantages; it is cheap, easy to install, and suitable for flame retardant and shielding heat convection.
The main products of glass fiber blank insulation type include: glass fiber needle mat, high silica glass fiber insulation
Unlike glass fiber, aluminum foil has unparalleled power in heat radiation, and aluminum foil is entirely waterproof and can be used in high-humidity environments; aluminum foil is lighter in weight, higher in strength, and lasts for a long time.
It is even simpler and saves time than fiberglass.
However, just like there is no perfect leaf in the world, the price of aluminum foil is slightly higher, the processing difficulty is somewhat more complicated than that of glass fiber, and its thermal conductivity is higher, so it is not suitable for direct use as a veneer insulation material.
But is there no perfect insulation solution?
Of course, there is. The ultimate solution for robust insulation.
When aluminum foil and glass fiber form a composite material, the problems caused by the three heat conduction methods are entirely blocked. This is Aluminum Foil Glass Fiber Blanket and Aluminum Foil Glass Fiber Fabric.
Aluminum foil glass fiber fabric is made by laminating glass fiber above grade E and aluminum foil.
The aluminum foil ensures that it can fully reflect the heat in the protected material. In contrast, the glass fiber blanket ensures that the R-value remains constant. The combination of the two-facing materials has become the most powerful choice in insulation.
Another representative work is the aluminum foil glass fiber fabric, which is different from the Aluminum Foil Glass Fiber Blanket. The glass fiber fabric is made of thinner glass fiber, so it is more suitable as a facing material in combination with aluminum foil.
