Aluminum-faced glass wool is a composite material with aluminum foil on the surface of glass wool, combining the excellent thermal insulation properties of glass wool and the moisture-proof and fire-resistant properties of aluminum foil.
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.

Making the final correct choice of insulation is never easy and straightforward, as many factors need to be considered in order to choose the most effective solution. All available insulation products have their advantages and disadvantages, depending on the area in which they are installed, external factors, climatic zones, humidity levels, accessibility of the space to be insulated, etc. This is why it is important to consider all aspects of insulation before making a final decision, as otherwise, you could risk an expensive project that ultimately does not achieve its intended purpose.
GET Glass Wool GET Foil-clad glass wool
The first thing we need to stress is that there is no "good" or "bad" insulation, as each product has its advantages and disadvantages compared to others, but a general comparative review can help you understand that some materials, although very efficient, are not This is due to certain other facts that need to be taken into account. To make your life easier, we will try to explain how to choose between glass wool and reflective foil insulation.
Glass fibre (or glass wool) is one of the world's most popular insulation materials and one of the most widely used products in the world. Its calming and easy installation, as well as its versatility (as it can be installed in almost any space), are probably the reasons for this. It is made from fine glass fibres, which are bonded by an adhesive added during the manufacturing process, and is usually packaged in rolls or blankets so that it can be installed almost anywhere - it can be rolled between roof or floor joints, inside walls or on ceilings.
Reflective foil insulation, on the other hand, is becoming increasingly popular because of its ability to reduce radiant heat. The reason why reflective foil insulation can often be used in roofs and attic spaces is that it reflects radiant heat from the sun and is therefore an excellent insulating material for insulation. Summer. It usually comes in the form of sheets or rolls of foil (aluminium foil is the most popular type of foil) which can be easily wrapped around joints or pipes.
To understand the basic difference between these two insulation types, apart from their softness, you need to understand that heat is transferred in three basic ways, namely convection, conduction and radiation. Well, the insulation mentioned above is designed to reduce and stop convective and conductive heat transfer, while its counterpart is primarily used to stop radiant heat transfer. Basically, radiant heat transfer can be stopped either by absorption (certain materials will absorb heat) or by reflection (by reflecting sunlight, for example, rather than letting them pass through).
As the name suggests, reflective foil insulation reflects radiant heat, which is important if you know that over 70% of the heat loss and gain in a building envelope comes from radiant heat transfer. This makes this insulation very useful in both winter and summer. On the other hand, alternative insulation is more effective in terms of convective and conductive heat transfer, which is why it is most commonly used to insulate internal walls.
Now that you understand the basic concepts of glass wool and reflective foil insulation, you need to understand their basic advantages and disadvantages.
the fact that it is one of the cheaper insulation materials, so there is no need to plan for much expense if this insulation is chosen
the additional fact that makes it cost-effective is that you can install it yourself without any professional help
it is much better at preventing convection and conduction heat transfer
it is easy to find and buy and has a lot of available information about its characteristics and the installation process.
it does not have the ability to stop radiant heat transfer
it is susceptible to moisture, dampness and mould, so additional protection is often required by installing a moisture barrier and a waterproof film.
it is completely safe for your health as it contains no harmful allergens that could be hazardous to your health
it is very durable, robust and lightweight.
it can easily be used in combination with other insulation materials
it prevents the transfer of radiant heat.
it is equally effective in preventing heat loss and heat absorption.
it is more expensive than alternative products
it cannot be used for convective and conductive heat transfer
It can be somewhat difficult to handle and install, depending on the installation space and material.
