Modern Upgrades During Renovation
One typical mistaken belief is that old windows must be cold and drafty. Specialist restorers use several technologies to bring 19th-century windows into the 21st century.
1. Draught Proofing Systems
By installing a perimeter sealing system, experts can decrease heat loss by approximately 30%. This includes routing grooves into the window elements to conceal brush seals that prevent air leakage while still permitting the sashes to slide smoothly.
2. Slimline Double Glazing
Specifically designed "slim" double-glazed units can sometimes be retrofitted into initial sashes. These units have a really thin profile (often 12mm to 14mm) and are filled with insulating gases like Krypton or Xenon. This permits the window to keep its fragile glazing bars while providing modern-day insulation.
3. Acoustic Glass
For homes found on busy roads, restoration professionals can install acoustic laminate glass. This substantially decreases sound pollution without changing the appearance of the window.
