Victorian sash windows often include "two-over-two" designs with ornamental "horns" to support the weight of heavier glass.Edwardian Windows (1901-- 1910): A hybrid style typically featuring a multi-pane upper sash over a single-pane lower sash, enabling optimum light while retaining a decorative thrive.

2. Draughts and Thermal Inefficiency
Standard single glazing and the intrinsic spaces needed for sash windows to move efficiently result in considerable heat loss. This typically causes a cold living environment and high energy bills.
3. Paint Seizure and Rattle
Years of over-painting can lead to windows being "painted shut." Alternatively, lumber shrinkage over a century can trigger sashes to fit loosely in their frames, leading to annoying rattles throughout windy weather.

High-performance epoxy resins are typically used to consolidate weakened wood and create a smooth, weather-proof bond between old and brand-new wood.
Draught-Proofing Installation
One of the most significant upgrades throughout restoration is the installation of a thorough draught-proofing system. This involves machining grooves into the sashes or beads and placing brush piles or silicone seals. This essentially gets rid of rattles and significantly lowers heat loss without altering the window's look.
Glazing Upgrades
While many pick to maintain initial crown glass for its "wavy" aesthetic, others choose "slimline" double glazing. These systems are thin enough to fit into initial Sash Window Services profiles, offering the thermal benefits of contemporary windows while keeping the thin glazing bars vital for a period look.
