Character and proportion
Sightlines, glazing bars and mouldings should relate naturally to the original building.
Windows
Heritage windows balance the character of an existing building with the comfort, security and performance expected from a modern installation.
Specified around your project
Period and conservation-sensitive projects need more than a visually similar replacement. Profiles, glazing, opening arrangements, finish and planning context all need to be considered together, with an honest view of what can be improved without losing character.
Key considerations
Sightlines, glazing bars and mouldings should relate naturally to the original building.
Listed and conservation-area work may require early discussion with the relevant planning authority.
Glazing and sealing choices can improve comfort while respecting the appearance of the elevation.
