Key components include:

• The Sashes: The movable glazed panels (upper and lower).

• Sash Cords: High-strength ropes that link the weights to the sashes.

. Slimline Double Glazing Standard double glazing is

typically too thick for initial sash frames. Professionals utilize “Slimline”or “Vacuum “glass (such as LandVac or Fineo), which offers the thermal efficiency of modern-day units but with a profile as thin as 6mm— 10mm. This permits the glass to suit conventional glazing bars without looking

bulky. Specialized Draught-Proofing Systems One of the main problems relating to old sash windows is the” rattle” and the “chill.” Specialists install discreet brush pile systems into the staff and parting beads. This gets rid of cold air ingress and avoids the sashes from vibrating in the wind, all while remaining undetectable

when the window is closed. Lumber Advancements

Specialists frequently utilize Accoya ® lumber. This is a chemically modified wood that is virtually rot-proof and does not swell or shrink with wetness. This fixes the olden problem of sash windows ending up being stuck during damp winter months.
