A typical misconception is that historical windows are inherently energy-inefficient. While a single-pane window has low thermal resistance, historical window installers have numerous tools to bring them up to modern-day standards.
Premium Storm Windows: Adding an outside or interior storm window can offer thermal efficiency almost identical to a modern double-pane window.Indow Liners: These are compression-fit interior inserts that provide soundproofing and insulation without needing any irreversible alterations.Vacuum Insulated Glass (VIG): This is a cutting-edge innovation where 2 panes of glass are separated by a vacuum.
