When choosing a sliding door, it is important to pay attention to the type of glazing option. The type of insulating glass on a sliding door, due to glass dimension, seriously affects its insulation factor. Because the cost of heating is continuously increasing, a glass with high energy properties will shortly pay for itself in economy and comfort.

There are three ways of increasing the insulation of an insulating glass built with two panes of glass:

Applying a transparent metallic coating.

Replacing the air between the two panes of glass with an inert gas.

An insulating glass spacer.
