Bombay Sliding Windows
The Bombay slider is the window most Lucknow homes are actually built around — a sash that slides sideways on rollers instead of swinging into the room, which matters when curtains, furniture or a balcony rail sit close to the frame.

What matters about this product
- Doesn't need swing clearance.
- The sash slides within the frame, so furniture, grills or curtains can sit close on either side.
- 2-track or 3-track configuration.
- 3-track adds a dedicated channel for mosquito mesh, so the mesh slides independently of the glass sash.
- Roller-mounted sash.
- Smooth operation depends on roller quality — this is the one part worth not skimping on, since it's what wears first under daily use.
- A top fixed vent is optional.
- A fixed toughened or frosted panel above the sliding sashes adds height and light without adding an opening section.
- Weather-sealed track.
- Wool-pile and gasket seals at the track reduce dust and rain ingress at the sill.
- Only half the opening ventilates at once.
- A sliding sash covers the other half of the frame when open — say so plainly, since a casement opens the full aperture and a slider does not.

Questions people actually ask
What's the difference between 2-track and 3-track?
2-track is glass sashes only. 3-track adds a dedicated channel for a sliding mosquito mesh panel, so the mesh can be opened and closed independently of the glass.
How much of the window actually opens?
About half the total width, since one sash always overlaps the other. For full-width ventilation, a casement or folding sliding door opens further.
Can I get a fixed glass section above the sliding sashes?
Yes — a top fixed vent in toughened or frosted glass is common for taller openings and adds light without an extra opening section to operate.
Does the roller wear out?
Rollers are the main wear part on any sliding window. Good rollers, kept free of dust in the track, last for years; a window used daily with cheap rollers is the first thing to feel sticky.
