Modern Upgrades During Renovation
One typical misunderstanding is that old windows need to be cold and drafty. Specialist restorers use numerous innovations to bring 19th-century windows into the 21st century.
1. Draught Proofing Systems
By setting up 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 prevent air leakage while still enabling the sashes to move efficiently.
2. Slimline Double Glazing
Specially designed “slim” double-glazed units can sometimes be retrofitted into initial sashes. These systems have a really thin profile (frequently 12mm to 14mm) and are filled with insulating gases like Krypton or Xenon. This permits the window to maintain its fragile glazing bars while providing modern-day insulation.
3. Acoustic Glass
For residential or commercial properties found on hectic roads, remodelling professionals can install acoustic laminate glass. This substantially minimizes sound pollution without altering the look of the window.
