Why use double glazing patio doors?

In a patio door, the glass unit itself is made up of two glass panes separated by an insulated aluminium spacer bar. This creates an air gap that improves insulation against heat transfer and sound transmission. Double glazing patio doors help to increase energy efficiency and provide other performance benefits.
