This "thermal buffer" minimizes drafts and helps preserve a consistent internal temperature, resulting in lower energy bills and a lowered carbon footprint.
2. Superior Acoustic Performance

In a double-glazed system, the 2 panes of glass are spaced really carefully together (normally 16mm to 20mm).
