Choosing aluminium heritage windows
The bar layout should follow the building.

Bring a photograph of the existing elevation. We can compare the positions and proportions of the bars across adjoining windows.

Decide which panes need to open for ventilation and where the handles will sit. The layout is confirmed for each opening at survey.

Letchworth homes, and what to check first.
The homes. Letchworth was the world's first garden city, begun in 1903. Its Arts and Crafts houses, cottages and later garden city estates give it a character unlike anywhere else nearby.
What that means. Windows and doors are a large part of that character, so replacements need to respect the original proportions, glazing bar patterns and colours of these houses.
Check first. The Letchworth Garden City Heritage Foundation runs a Scheme of Management across much of the town, and its consent is needed for changes to windows and doors. Apply before you order.

Great service from Fenster Glazing, very happy with our new bi-fold door, glass door and windows (with built-in blinds) There was an issue with the wrong spec of glass provided to them from their supplier, so they had to temporarily board up a door and a window, but this was put right within a few weeks. Recommended, thanks.
