Among the primary problems regarding original sash windows is their poor thermal insulation. Historically, these windows featured single-pane glass, which uses very little resistance to heat loss. Throughout the refurbishment procedure, there are two primary methods to address this:
1. Advanced Draught-Proofing
By setting up an extensive draught-sealing system, air leak can be minimized by as much as 80%. This not only keeps the property warmer but likewise significantly decreases external noise and prevents dust and pollen from going into the home.
2. Slim-Profile Double Glazing
Sometimes, the initial sashes can be modified to accommodate "Slimlite" or vacuum-sealed double-glazing units. These units are thin sufficient to suit the original glazing bars, providing the thermal benefits of contemporary windows without the large appearance.
