Heritage double glazed units, therefore, have been designed to fix all these. These windows achieve a slender and graceful profile of traditional windows while improving their performance. Advanced glazing technologies enable manufacturers to create superior insulation units without compromising aesthetics.
The principle behind heritage double glazing is slimline glazing. In essence, the gap between the two panes is smaller than usual, with a typical size between 4 mm and 6 mm as opposed to the standard 20 mm that might be found in regular double glazing. This slimmer profile will make any new glazing unobtrusive to the appearance of the original window, maintaining a building's historic charm.
