A bay window projects outward from the building wall, typically with three glass panels meeting at angles — one center pane facing outward and two side panes at 30 or 45 degrees. The effect is dramatic: extra light, the sense of additional floor space, and a clear architectural feature on the elevation. Bay windows aren't common in standard Coimbatore homes but they're increasingly specified in premium renovations and new builds. Glassterr manufactures them at our Pannimadai factory — the center pane can be fixed picture glass, opening casement, or sliding; the side panes are typically opening casement for ventilation. The construction is more involved than a flat window because the corner joins are structural.
A bay window is essentially three (sometimes five) connected windows arranged in a polygon projecting from the wall. The most common is the 'three-pane bay' — one large center pane parallel to the wall, two smaller side panes at angles. The 'projection depth' is typically 30-60 cm from the wall. Structurally, the corner mullions where the panes meet do the load-bearing work; depending on the projection size, additional support may come from a small ceiling-side beam (above) or a sill console (below). The interior gets a wide sill — often used as a window seat or display shelf — which adds usable space to the room.
Depends on whether you're adding a bay to an existing window opening or creating one new. Existing wide opening: usually fine, we work within the lintel. New cut: needs an RCC lintel and possibly load-bearing assessment. We'll inspect the wall at measurement and tell you honestly.
Window seats are the most popular — a cushioned bench across the inside of the bay. Display shelves for plants or books. A small reading nook. A breakfast bar in a kitchen bay. The 30-60 cm of additional depth is genuinely useful space.
Yes — the two side panes are typically opening casement, so you get good cross-ventilation across the bay even when the center pane is fixed. Three panes opening would be overkill for most rooms.
Roughly 2-3× the cost of an equivalent-width flat window — because there are three windows being manufactured, plus the structural corner work, plus more involved installation. A 6ft × 5ft bay window typically runs ₹60,000-1,20,000 depending on configuration.
Yes, but check the math. A small bedroom (10×10 ft) with a 6ft bay projecting 45 cm into the room loses about 8 sqft of floor area — but gains roughly the same as functional sill space. Net usually positive but it changes how the room feels. We'll discuss before quoting.
