Modern Upgrades During Renovation
One typical misunderstanding is that old windows must be cold and drafty. Specialist conservators utilize numerous technologies to bring 19th-century windows into the 21st century.
1. Draught Proofing Systems
By setting up a boundary sealing system, specialists can decrease heat loss by approximately 30%. This involves routing grooves into the window elements to hide brush seals that prevent air leak while still permitting the sashes to move efficiently.
2. Slimline Double Glazing
Specifically designed "slim" double-glazed systems can in some cases 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 fragile glazing bars while providing modern-day insulation.
3. Acoustic Glass
For properties located on busy roadways, remodelling specialists can set up acoustic laminate glass. This substantially minimizes sound contamination without changing the appearance of the window.
