Modern Upgrades During Renovation
One common misunderstanding is that old windows need to be cold and drafty. Specialist restorers utilize several technologies to bring 19th-century windows into the 21st century.
1. Draught Proofing Systems
By installing a border sealing system, specialists can reduce heat loss by approximately 30%. This includes routing grooves into the window parts to hide brush seals that avoid air leakage while still enabling the sashes to slide efficiently.
2. Slimline Double Glazing
Specifically designed “slim” double-glazed units can often be retrofitted into initial sashes. These units have an extremely thin profile (typically 12mm to 14mm) and are filled with insulating gases like Krypton or Xenon. This allows the window to maintain its delicate glazing bars while supplying modern-day insulation.
3. Acoustic Glass
For residential or commercial properties found on hectic roadways, remodelling experts can set up acoustic laminate glass. This significantly reduces sound pollution without changing the look of the window.
