One common misunderstanding is that old windows need to be cold and drafty. Specialist restorers use numerous innovations to bring 19th-century windows into the 21st century.
1. Draught Proofing Systems
By installing a perimeter sealing system, professionals can lower heat loss by up to 30%. This involves routing grooves into the window elements to conceal brush seals that avoid air leakage while still allowing the sashes to slide efficiently.
2. Slimline Double Glazing
Specifically developed "slim" double-glazed units can sometimes be retrofitted into original sashes. These systems have a very thin profile (often 12mm to 14mm) and are filled with insulating gases like Krypton or Xenon. This permits the window to retain its delicate glazing bars while providing modern-day insulation.
3. Acoustic Glass
For properties located on busy roadways, restoration specialists can install acoustic laminate glass. This substantially lowers noise pollution without changing the appearance of the window.
