One typical misconception is that old windows need to be cold and drafty. Expert conservators make use of a number of technologies to bring 19th-century windows into the 21st century.
1. Draught Proofing Systems
By setting up a border sealing system, experts can lower heat loss by up to 30%. This involves routing grooves into the window elements to hide brush seals that prevent air leakage while still enabling the sashes to move smoothly.
2. Slimline Double Glazing
Specially developed "slim" double-glazed systems can in some cases be retrofitted into original sashes. These systems have an extremely thin profile (often 12mm to 14mm) and are filled with insulating gases like Krypton or Xenon. This enables the window to keep its fragile glazing bars while offering contemporary insulation.
3. Acoustic Glass
For residential or commercial properties found on busy roads, remodelling specialists can set up acoustic laminate glass. This considerably reduces sound pollution without altering the look of the window.
