Modern Upgrades During Renovation
One common mistaken belief is that old windows must be cold and drafty. Expert conservators use numerous innovations to bring 19th-century windows into the 21st century.
1. Draught Proofing Systems
By setting up a border sealing system, professionals can minimize heat loss by approximately 30%. This includes routing grooves into the window parts to hide brush seals that prevent air leakage while still permitting the sashes to move smoothly.
2. Slimline Double Glazing
Specially designed “slim” double-glazed units can often be retrofitted into initial sashes. These units have a very thin profile (often 12mm to 14mm) and are filled with insulating gases like Krypton or Xenon. This allows the window to keep its delicate glazing bars while providing contemporary insulation.
3. Acoustic Glass
For residential or commercial properties located on hectic roads, restoration professionals can set up acoustic laminate glass. This substantially decreases sound pollution without changing the appearance of the window.
