Modern Upgrades During Renovation
One common misunderstanding is that old windows need to be cold and drafty. Professional conservators use several innovations to bring 19th-century windows into the 21st century.

Specifically created "slim" double-glazed systems can often be retrofitted into initial sashes. These systems have a very thin profile (often 12mm to 14mm) and are filled with insulating gases like Krypton or Xenon.
