Low-E...

Low-emissivity glass or Low-E glass as it is more commonly referred to, is a type of energy-efficient glass designed to prevent heat escaping through your windows to the cold outdoors.

When heat or light energy is absorbed by glass, it is either convected away by moving air or reradiated by the glass surface. The ability of a material to radiate energy is called its emissivity. All materials, including windows, emit (or radiate) heat in the form of long-wave, far-infrared energy depending on their temperature. This emission of radiant heat is one of the important components of heat transfer for a window. Thus reducing the window’s emittance can greatly improve its insulating properties.

U-values...

U-values measure the effectiveness of a material as an insulator in buildings.

Expressed in W/m2k, it shows the amount of heat lost in watts (W) per square metre of material when the temperature (k) outside is at least one degree lower.

If we look at typical U values for glazing, single pane glass units have a U value of 5, older double glazed units have a U value of 3, and modern double glazed units have a U value of 1.6

To reach the forecasted target of U value 0.8, glazing has to be produced to higher standards, using more expensive manufacturing techniques, filling cavities with more expensive gasses (like krypton) instead of argon.

The lower the U-value, the better the insulation provided by the material.
