Draught-Proofing Installation
One of the most significant upgrades throughout renovation is the installation of a comprehensive draught-proofing system.

This virtually gets rid of rattles and considerably minimizes heat loss without modifying the window's appearance.
Glazing Upgrades
While lots of select to keep initial crown glass for its "wavy" visual, others choose "slimline" double glazing. These systems are thin sufficient to fit into original sash profiles, offering the thermal benefits of contemporary windows while keeping the thin glazing bars important for a period Window renovation appearance.
