Product Description:


Building insulation material for construction is a brand new heat insulation product manufactured of polyethylene bubble/foam sheet faced with aluminium foil on the one or two sides. It can reflect 97% radiant heat and reduces energy costs used in winter heating and summer cooling. Reflective Foil thermal insulation is only a few millimeters thick, its two sides of aluminium foil reflects more than 97% thermal energy that reaches it .In summer, almost all the sunlight and heat is bounced back into the air, Keeping the heat out of the air conditioned building. In winter, Almost all the heat generated inside the building is retained. Also, The bubble/foam sheet in between the aluminium foil offer thousands of empety air cells, which makes the heat more difficult to pass through.

FAQ:
 1.How does Reflective Aluminum Foil Insulation work?
Reflective Aluminum Foil Insulations don't absorb heat, they block the flow of radiation.? Installing Reflective Aluminum Foil between the heat source (sun) and an existing insulation will improve the effectiveness of the R-Value rated insulation.?The reason is that only little part of the heat is now hitting the R-Value rated insulation and therefore, it will take longer for it to absorb 100% of its potential thereby holding the heat longer before passing out the back side into the room. Reflective Aluminum Foil reflects up to 97% radiant heat striking its surface.

2.How to install Reflective Aluminum Foil Insulation correctly?
It is important to maintain at least a 3/4" air space on the side of the radiant barrier you want to reflect heat. So you can prevent introducing any conductive heat flow to the aluminum to the aluminum foil facing and improve the efficiency for insulation.

3.What is R-value?
An R-Value is a measure of how long it takes a insulation to absorb 100% of its potential and begin to transfer the heat out the other side of the product. The higher the better.

4.Does Reflective aluminum foil insulation has a R-Value?
Reflective Aluminum Foil insulation doesn't have a R-Value, but for its ability to highly reflect the radiant heat and imperviousness to convection current(another way of heat transfer), it can improve the efficiency of insulation greatly.

5.What is a radiant barrier?
A radiant barrier is a layer of metallic foil that blocks radiated heat. Radiant barriers are generally installed in an attic directly under roof rafters to reduce unwanted heat gain from the sun. A radiant barrier material should be more than 99% aluminum and the emissivity value should be 2-5%.

6.What is Emissivity?
Emissivity is an indication of a surface's ability to emit heat by long-wave radiation. Most foil type radiant barriers have an emissivity of 0.05 or below, which means 95% of the radiant heat is being blocked.

7.Heat transfer mechanisms usually are grouped into 3 broad categories: 
A. Conduction:Transfer of energy through matter from particle to particle. Areas of greater molecular kinetic energy will pass their thermal energy to areas with less molecular energy through direct molecular collisions. 
B. Convection:Transfer of heat energy in a gas or liquid by movement of currents. The heat moves with the fluid. It includes free convection and forced convection.
C. Radiation:Electromagnetic waves directly transport energy through space. Sunlight is a form of radiation that is radiated through space to earth. Bright, shiny materials reflect radiation while dull, black materials absorb it.

8.Why an airspace is necessary adjacent to the radiant barrier?
When aluminum foil is in direct contact with another surface, it conducts heat at the points of contact. An air space will prevent conduction and allow the foil surface to reflect radiant heat.

9.What is the percent the radiant can reflect?
Aluminum foil reflects up to 97% of radiant heat.

10.Why should use aluminum foil insulation? 
Approximately 75% of heat transmission is by radiation, most material used on building absorb radiantion heat and re-radiate it, hwihc makes the room temperature much higher than outside, and have Air-conditioning to work constantly. But aluminum foil insulation can reflect 97% radiation heat, so it save your energy bill and provide you
