Reflective insulation is typically made up of aluminium and also well-known as a DIY radiant barrier. It appears like metallic foil and has a reflective covering. It is very handy and very easy to install.
In the use of reflective insulation, its primary purpose is to prohibit radiant heat from transmitting across open spaces. Reflective insulation decreases energy bills in the summer, particularly in the warmer climates. This can also be used in some cases to reduce heating costs.
Every type of insulation on the market comes with an R-value. The R-value is rated corresponding to a piece of insulation's thickness and density. The R-value of reflective insulation is calculated by how the heat flows in the home.
Reflective insulation is same in principle to every other forms of insulation considering that they reduce the amount of heat that penetrates or exits a home. Various kinds of insulation trap air within the insulation, not permitting it to escape. Reflective insulation is effective to minimize the flow of heat throughout an open airspace.http://youtu.be/uVSOqY-NrjE
