Thermal insulation performance of aluminum foil composite bubble film

Thermal insulation performance of aluminum foil composite bubble film Introduction to Aluminum Foil Thermal Insulation Roll:
Aluminum foil insulation roll is a new type of insulation product, which is made by pressing aluminum foil veneer, polyethylene film, fiber woven fabric, and metal coating through a hot melt adhesive layer. It has functions such as insulation, waterproofing, and moisture resistance. Its solar radiation absorption coefficient is extremely low, which can isolate most of the heat transfer. The product has been widely used in the roofs and exterior walls of building structures, playing a role in thermal insulation.
The working principle of insulation film products:
Heat transfer in building heat exchange is manifested in three ways: conduction heat+convective heat<25%, radiant heat>75%.
After the temperature of the tiled roof rises in summer, a large amount of radiant heat enters the room, causing the temperature to continue to rise, making the working and living environment extremely uncomfortable.
The solar radiation absorption coefficient (normal total radiation emissivity) of aluminum foil coil is 0.07, and the radiated heat is very low. Compared with other insulation materials, aluminum foil insulation rolls are widely laid, and the thermal bridge (cold bridge) is well treated, providing insulation effect in summer and good insulation function in winter, thus truly achieving the goal of energy conservation.
Thermal energy transmission route (without aluminum foil): sunlight - infrared magnetic waves - thermal energy hitting tiles to increase temperature - tiles become heat sources and emit thermal energy - thermal energy hitting cast-in-place roofs to increase temperature - cast-in-place roofs become heat sources and emit thermal energy - indoor environmental temperature continues to rise
Thermal energy transmission route (with aluminum foil roll): sunlight - infrared magnetic waves - thermal energy hitting tiles to increase temperature - tiles become heat sources and emit thermal energy - thermal energy hitting the surface of aluminum foil bubble film. The main advantages of the product are:
(1) The thermal insulation effect. The solar radiation absorption coefficient (normal total radiation emissivity) of aluminum foil coil is 0.07, and the radiated heat is extremely low. Designing and installing according to a certain plan can effectively reduce heat radiation, heat conduction, and heat convection, thereby achieving ideal insulation and energy-saving effects.
(2) Good waterproof and moisture-proof performance. The sealing design of aluminum foil coil can effectively prevent the penetration of water vapor. At the same time as providing insulation, it also provides an excellent waterproof and vapor barrier to enhance the water and air tightness of the building, and prevent the occurrence of heat convection.
(3) The tensile strength of *. Practice has proven that when the tensile strength of the material reaches 600N/50mm, it can meet the requirements of complex roof construction. The longitudinal strength of aluminum foil roll can reach 650N/50mm, and it is not easily damaged during construction.
(4) Easy installation and construction, saving labor costs. The standard specification for aluminum foil roll is 1.2m * 50m * 0.16mm, with a weight of only 120g per square meter. It is lightweight, easy to construct, and has low labor costs. This material is soft, lightweight, and easy to install. It has the characteristics of heat insulation, thermal insulation, waterproofing, and moisture resistance. This product is environmentally friendly. Its appearance not only solves the discomfort and environmental hazards caused by traditional glass fiber and foam materials such as rock wool and glass felt, but also blocks the thermal infrared that cannot be blocked by penetrating iron sheets, concrete, wood, and ordinary insulation materials. There are usually three methods for roof insulation: 1. Air insulation method is to cover a hollow interlayer of about 30 centimeters on the roof, which can effectively isolate the heat transfer effect when exposed to sunlight in summer because the air flows underneath. 2. Water insulation method requires high quality for the roof. The roof is usually a shallow water layer, about 15 centimeters deep, which can also provide some insulation effect.

This is a new type of environmentally friendly insulation material that is soft, lightweight, and easy to install; Its structure is made of aluminum foil and polyethylene, processed by special machinery. This product is non-toxic and odorless. Its appearance not only solves the discomfort and environmental hazards caused by traditional glass fiber and foam materials to the human body, but also prevents ultraviolet rays that can penetrate through iron sheets, concrete, wood, and ordinary insulation materials and enter the room. This type of insulation material has good insulation, heat reflection, insulation, and anti radiation functions on the one hand; On the other hand, its material properties can play a good role in moisture resistance, insulation, and energy conservation in building applications such as roofs, walls, and floors.

Function:
Can be installed on roofs, walls, or floors, providing 80% protection for buildings from the outside world

The above thermal energy barrier function protects walls and resists sudden temperature increases and decreases.

2. Lightweight, soft, dust-free, flame retardant, easy to install;
3. It has functions of heat reflection, insulation, sound insulation, anti radiation, shock resistance, and shielding;
4. Moisture proof, sun proof, waterproof, good sealing, and energy-saving insulation;
5. Summer: moisture-proof, sunscreen, heat insulation, saving air conditioning;
6. Winter has a thermal insulation effect, which can save heating and have significant energy-saving effects.

Purpose:
1. Roofs, walls, and floors;
2. Air conditioner and water heater jacket;
3. Outer protective layer for water pipes and ventilation pipes

Installation method:

Method 1

The simple method is to use waterproof double-sided tape, and the membrane to membrane joints should be firmly attached with waterproof double-sided tape. Then, use waterproof pure aluminum tape to stick the overlapping areas of the membrane and the membrane to the ground or glass.

Method 2

It is to use small long iron sheets or PVC tapes to press down on the insulation material. Just add willow nails or small steel nails on top of the insulation material

Method 3

Iron roof: Once the iron shed is ready, it can be directly installed by drilling holes with sun panels and aluminum pressure strips and installing core nails. It only needs to be windproof, and the cotton surface can be coated with gloss oil for durability;

Alternatively, iron wires can be used to secure or install suspended ceilings underneath the iron tiles. For the newly made iron shed, first lay insulation cotton on the steel frame, fix the four corners with zip ties, overlap the two pieces by 10 centimeters, and cover them with iron tiles.

Method 4

Cement roof: Just use bricks or something to press down on it to prevent wind damage. After August, it can be stored and laid next year, which is more durable. Alternatively, use a polycarbonate sheet with aluminum pressure strips, add 1.5cm small steel nails, and nail them onto the cement surface (this can also be done for Western style walls). If installed on the ceiling below the roof, it would be better to install a wooden frame like a suspended ceiling.
