  • Victorian Windows (1837-- 1901): As glass manufacturing improved, bigger panes ended up being popular. Victorian sash windows often feature "two-over-two" styles with ornamental "horns" to support the weight of much heavier glass.

2. Draughts and Thermal Inefficiency

Conventional single glazing and the fundamental gaps required for sash windows to slide efficiently lead to considerable heat loss. This often results in a cold living environment and high energy costs.

3. Paint Seizure and Rattle

Years of over-painting can result in windows being "painted shut." Alternatively, lumber shrinkage over a century can cause sashes to fit loosely in their frames, resulting in annoying rattles throughout windy weather.

Lumber Repair and Resin Splicing

Instead of replacing a whole frame, specialists utilize "splice repairs." Rotted sections are removed and changed with matching seasoned timber. High-performance epoxy resins are typically used to consolidate weakened wood and create a seamless, weather-proof bond in between old and new wood.

Draught-Proofing Installation

One of the most considerable upgrades during renovation is the setup of a thorough draught-proofing system. This involves machining grooves into the sashes or beads and inserting brush stacks or silicone seals. This essentially eliminates rattles and significantly decreases heat loss without modifying the window's appearance.

Glazing Upgrades

While lots of choose to retain initial crown glass for its "wavy" aesthetic, others opt for "slimline" double glazing. These systems are thin enough to suit original sash profiles, offering the thermal advantages of contemporary windows while preserving the thin glazing bars vital for a period appearance.
