One typical misconception is that old windows should be cold and drafty. Expert restorers utilize a number of technologies to bring 19th-century windows into the 21st century.
1. Draught Proofing Systems
By installing a boundary sealing system, specialists can lower heat loss by as much as 30%. This involves routing grooves into the window components to hide brush seals that avoid air leakage while still allowing the sashes to move smoothly.
2. Slimline Double Glazing
Specially designed "slim" double-glazed systems can in some cases 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. This permits the window to retain its delicate glazing bars while offering contemporary insulation.
3. Acoustic Glass
For residential or commercial properties found on hectic roadways, remodelling experts can set up acoustic laminate glass. This considerably decreases noise contamination without altering the appearance of the window.
