Choosing roof lanterns
Choose the lantern around the room beneath it.
Position and size
Think about the kitchen island, dining table and lighting below. We review the structural opening and upstand details with the roof design.

The glazing affects daylight and solar gain. Tell us how much sun reaches the roof so we can discuss an appropriate glass specification.

Compare the frame colour inside and out. Access, the upstand and the roof finish are checked before the lantern is ordered.

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.

Product choices, pricing and what happens before we fit.
Should I choose a roof lantern or a flat rooflight?
A lantern rises above the roof with an angled glazed structure; a flat rooflight has a flatter profile. The room layout, roof opening and appearance you want help determine the choice. We can review both with your drawings.

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.
