Modern Upgrades During Renovation
One common misconception is that old windows need to be cold and drafty. Specialist restorers make use of numerous technologies to bring 19th-century windows into the 21st century.
1. Draught Proofing Systems
By setting up a border sealing system, specialists can lower heat loss by approximately 30%. This includes routing grooves into the window components to hide brush seals that prevent air leakage while still permitting the sashes to slide efficiently.
2. Slimline Double Glazing
Specifically developed “slim” double-glazed systems can often be retrofitted into initial sashes. These systems have an extremely thin profile (typically 12mm to 14mm) and are filled with insulating gases like Krypton or Xenon. This enables the window to maintain its delicate glazing bars while supplying modern insulation.
3. Acoustic Glass
For homes located on busy roadways, remodelling experts can install acoustic laminate glass. This substantially lowers sound pollution without changing the appearance of the window.
