Modern Upgrades During Renovation
One typical misconception is that old windows must be cold and drafty. Specialist conservators use several technologies to bring 19th-century windows into the 21st century.
1. Draught Proofing Systems
By installing a boundary sealing system, experts can reduce heat loss by up to 30%. This includes routing grooves into the window elements to conceal brush seals that avoid air leak while still allowing the sashes to move smoothly.
2. Slimline Double Glazing
Specifically developed “slim” double-glazed units can often be retrofitted into original sashes. These systems have a very thin profile (often 12mm to 14mm) and are filled with insulating gases like Krypton or Xenon. This enables the window to keep its fragile glazing bars while supplying modern insulation.
3. Acoustic Glass
For residential or commercial properties found on hectic roadways, restoration specialists can install acoustic laminate glass. This substantially minimizes noise contamination without altering the appearance of the window.
