Online LOW-E color monotonous, (it is said that now also developed several colors), energy-saving effect than the low two grades, and the light transmittance and color is generally dead, not adjustable, but he can be monolithic, Will not be oxidized, only those who do not require high owners and must use monolithic online LOW-E, offline color and light transmittance theoretically free to adjust, according to the owner or design preferences to adjust the energy saving effect U value Generally below 1.8, but the disadvantage is that the synthesis must be used.
Personally think that online Low-e is better than offline, because the stability is good and easy to use monolithic, and can be thicker, such as 8mm, 10mm, 12mm have.
No good or bad, only right inappropriate!
Online Low-e advantage is that you can use monolithic, the general use of life in more than 15 years, offline Low-e must be made of insulating glass, so the specific use depends on your request.
