low-e insulated glass

SM009 Low-e insulated glass Heat insulation ,Aesthetic and confort. U valune is the parameter to measure the ability of a material to conduct heat ,the lower the U value is the better the heat insulation is to reduce the radiation,convection or conduction can lower the U value effectively.For windown the radiation heat loss via the glass occupies about 2/3 of the total heat loss,so it is obvious the U Value could be dramatically decreased by using low-e coated glass in IGU.
