Consist one woven layer of foam laminated with both side pure aluminium foil to provide excellent resistance.

Mainly by using the barrier property of foam and the light blocking principle of aluminum foil.The foam layer designed increased strength and resistaned puncture in addition to resisting sound.Foam foil provides neat appearance, and reflects up to 97% heat radiant from heat source such as sun.In many applications, radiation is the dominant mode of heat transfer.

The thermal insulation concept of heat transfer is that the hot sun rays are bounce from the surface ofaluminum foil and stops hitting the inner environment. Therefore it gives stable heat inside the house withthe increase or decrease of temperature outside and saves energy consumption.

Thermal roof insulation material is versatile in use as it can be used to covers the roofs, ceilings, crawlspaces, wall and attics and even utilize for packaging purposes. Such radiant barrier film is also used formobile house insulation. Large scale steel building and concrete structure can also be insulated withfoam insulation by pre engineered building insulation.

The term “sarking” is used in several different ways in construction. In general, it is a panel which is used as an underlayment, and may be used in the construction of walls, or in the construction of a roof. In walls, people may refer to “scrim and sarking” construction, a technique used in many older homes. People doing refurbishment and repair of such homes may opt to reproduce this building technique to preserve the character of the structure.

On a roof, sarking is used as part of the underlayment or roof membrane. It acts as a barrier to prevent moisture from entering the roof and the home, and also helps to reflect heat. The underlayment will help a home stay cool in the summer and will keep warmth inside during the winter, keeping temperatures stable. It can also help make a roof more wind resistant, which can be valuable in some climates.

Several materials can be used for sarking on a roof. Historically, it was done with boards known as sarking boards which were laid under the tiles, shingles, or other roofing materials used. Modern underlayments may be made from felt or other materials, and it is often laid over a secondary barrier material. It is common for roofs to include several layers of underlayment in their construction, and this may in fact be required by building code in some regions of the world

Aluminum sheet is an ideal thermal Insulation paper to prevents heat from escaping or block radiant coming by pasted to surface glass wool for the purpose of reflection to increase the affection of heat insulation considering the thickness of aluminum foil is too low therefore easy to broken。

Foil woven fabric is considered as a good building material because of outstanding toughness offers greater protection against breakage during transportation, installation and usage. It will not corrupt because of 100% Inorganic raw materials, and flexible allow install in variety of shape. 97% reflecting rate, could reflective most solar energy effectively. Further, perforated materials are also available to avoid moisture and condensation problem.

Function:

• Water, corrosion, light can be prevented effectively.
• for keeping warm ground, warm wall, moisture-proof floor, etc.
• Eco-friendly .insulation,.water-proof,oil resistant, etc.
• For construction,OEM is available.

Aluminum foil possesses some unique qualities that allow it to offer all these insulation perks. First, because its mass is insignificant, its absorption and retention of heat is improved. Second, its E-values (i.e., emittance values) are very low. Therefore, heat transfer by radiation is minimized.

Benefits

Because aluminum foil reflects light, it can be used for insulation, especially in areas that need to be guarded against heat. When it is used with other materials, it can be used to warm an area, too. Other materials such as paper and cotton, do not have the reflectivity that aluminum foil does, so when the sun is bearing down, they will not keep it out as well. An area that is already hot will be kept hot by aluminum foil, as it will hold in hot air. Paper and cotton will release heat at a quicker rate than aluminum foil. Aluminum foil can keep things like wires or pipes insulated, as it traps air when it is wrapped around an object. This can be achieved with several objects, though, and not just aluminum foil.

Considerations

If you would like to insulate something in a dark place, such as lunch box, another material such as cotton or paper could work just as well as aluminum foil. As a matter of fact, cotton is regularly used for insulation, as it is environmentally friendly. Because aluminum foil reflects light, when it is in a dark place, there is no light for it to reflect, so it will work similarly to other materials.

The scientist of NASA were confronted for developing an insulation that can protect their astronauts from extreme high temperature in the sky. The traditional insulation material was impossible to use as it requires very thick surface that ranges around several feet and it was unconventional to wear those dresses in space craft. The solution for this major problem was to use the reflective aluminum foil insulation for making a barrier wall on their dresses.

Aluminum thermal insulation is work on the radiant barrier principal that reflects the temperature and sun rays back to atmosphere from where they are coming from. And it works in both hot and cold environment by reflecting high temperature rays to the direction of source. The same can enhanced with the use of polyethylene bubble insulation film that sandwiched between the aluminum foil. Though aluminum insulation reflects around 97 percentage of sun rays and radiant heat, remaining can be stop passing to home by air bubble film. And this is why most of the radiant barriers are the best choice for home and industrial temperature insulation.

This aluminum roof insulation is used to provide protection against the higher cold also as it reduces the temperature loss to outers surface of the home roof or wall. Particularly for the building that are made with higher amount of glass or steel. Whatever needs to be of keeping the close room at a constant temperature, it can be benefited with the use of radiant aluminum foil.

Studies have shown that radiant heat transmission is responsible for the highest amount of heat gain or loss in the building structure. During the hard summer, the ceiling or roof and wall of the building absorb radiation from the sun rays and transmit it inside the home. The same heat is then transmitter towards the attic room. However, most of the sun rays and heat is transmitted outside when radiant aluminum foil insulation is used. Also during the colder period the same thermal barrier stops the wastage of energy by reflecting cooler temperature towards the interior of the building. A properly installed aluminum thermal barrier stops 97 percentage of the heat transfer and saves money and energy both.

Aluminum foil thermal insulation can be used to multiple places where it can be found useful for stopping unwanted heat gain or heat loss. Aluminum foil insulation works effectively and efficiently and prevents the transmission of temperature that at the end results into wastage of energy.

Insulation materials heat transfer model is very important, heat through conduction, convection or radiation transfer, or by a combination of all three. Heat is always transferred from warm to cold areas; it seeks balance.

Conduction. By this mode, heat energy is passed through a solid, liquid or gas from molecule to molecule in a material. In order for the heat to be conducted, there should be physical contact between particles and some temperature difference. Therefore, thermal conductivity is the measure of the speed of heat flow passed from particle to particle. The rate of heat flow through a specific material will be influenced by the difference of temperature and by its thermal conductivity.

Convection. By this mode, heat is transferred when a heated air/gas or liquid moves from one place to another, carrying its heat with it. The rate of heat flow will depend on the temperature of the moving gas or liquid and on its rate of flow.

Radiation. Heat energy is transmitted in the form of light, as infrared radiation or another form of electromagnetic waves. This energy emanates from a hot body and can travel freely only through completely transparent media. The atmosphere, glass and translucent materials pass a significant amount of radiant heat, which can be absorbed when it falls on a surface (e.g. the ship’s deck surface on a sunny day absorbs radiant heat and becomes hot). It is a well known fact that light-coloured or shiny surfaces reflect more radiant heat than black or dark surfaces, therefore the former will be heated more slowly.

I hear people ask about foil insulation a lot and the first thing I have to do is stop them and give an explanation about what insulation is.

Insulation, in the context of what you are going to stuff into your attic, is a material that slows down the transfer of heat. Its really that simple. Fiberglass insulation, cellulose insulation, spray foam insulation and even rock wool are ways to slow down the movement of heat. We either want to keep heat out or in. Insulation can do this.

What people refer to as foil insulation or reflective insulation, is not really insulation at all. It does not slow down the transfer of heat. There is no R-Factor to it.

What foil does best, when installed properly, is to REFLECT the heat away. There is no slowing involved. As a reflective surface, the idea is to create a radiant barrier in your attic that the infra-red rays cannot get past. You will have a barrier that stops heat from radiating into your home (hence where the name comes from).

Foil bubble insulation, whether it is Reflectix, ARMAFoil, RadiantGuard, Polarlum, Ecofoil, or any other brand can actually qualify as insulation. Unlike the regular foil, it has bubble wrap sandwiched between the foil. This bubble wrap, whether a single layer or a double layer slows down the flow of heat. Admittedly, the R-Value of bubble wrap is not impressive, but it does end up being a thermal break. this being the case, you can argue the case of foil bubble being insulation.

The bottom line is that a radiant barrier attic needs both the foil to block the radiated heat and insulation to stop the flow of convective and conductive heat. That is the only way to ensure that you really are stopping the heat from getting into or out of your home.
