Domal Windows
Domal-profile windows use a more precisely extruded aluminium section than a standard slider — narrower visible frame, tighter tolerances at the joints, and a smoother roller action. The mechanism is the same sliding idea as a Bombay window; the difference is in the finish and the fit.
What matters about this product
- Slimmer sightlines.
- A narrower visible frame section means more glass area for the same rough opening.
- Tighter joinery.
- Precision extrusion holds corner joints flush, which shows in how cleanly the frame sits against the wall.
- Better weather-sealing at the track.
- Wool-pile and gasket detailing is tighter than entry-level sliders, cutting dust and rain infiltration at the sill.
- Smooth, quiet roller action.
- Worth the difference on a window used daily — a slider that sticks gets forced, and forced hardware fails first.
- No thermal break as standard.
- Like most fabricated aluminium windows in this market, plain aluminium conducts heat — ask about a DGU build-up if thermal performance matters more than cost.
- Same finish options as any Gopalsons window.
- Powder-coated or anodized to the shade of your choice, since coating happens in-house at New Indira Steels.

Questions people actually ask
How is a Domal window different from a Bombay sliding window?
Both slide on rollers; the difference is the extrusion — Domal profiles are more precisely made, with a slimmer sightline and tighter sealing at the joints and track. It's a finish-and-fit upgrade, not a different mechanism.
Is it worth the difference over a standard slider?
For a street-facing elevation or a room where the window is a visible design element, the slimmer frame and cleaner joints are noticeable. For a utility or back-of-house opening, a standard slider does the same ventilation job for less.
Does it come with a thermal break?
Not as standard — like most aluminium windows fabricated in this market, it's plain aluminium, which conducts heat. If reducing heat gain or loss matters more than cost, ask about a DGU (double-glazed) build-up instead.
What glass options work with this frame?
The full range — toughened, tinted, frosted, laminated — in 5mm or 6mm, or a DGU unit where thermal or acoustic performance is the priority.
