25 Jun What is double glazing?
Also called Insulated Glass, Double Glazing comprises of two glass panels. An inert gas which does not conduct energy is inserted between two glass panels, so that the heat energy is prevented from passing through significantly. The gap between the two panels in Double glazing contains a spacing which is normally 12 mm to 20 mm deep. The inert gases that can be used are Argon, Krypton & Xenon. But the most popular is Argon due to its economy.
Then what is low emissivity Glass?
Low emissivity glass is also a type of Double Glazing which has a coating of low emissivity in the inner side of one glass pane. This does not require the filling of Argon gas.
