INVISIBLE GRILLS • PUNE INSTALLATION

Invisible Grill for French Windows

A French window isn't really a window — it opens floor to ceiling like a door, which is exactly why most homeowners leave it ungrilled. A standard iron window grill would block the opening entirely, so the choice usually ends up being either no protection at all, or a grill that defeats the point of having French windows in the first place. That's a real gap, especially on upper floors where the drop is the actual hazard, not just a partial window opening. Our french window safety grill uses vertical SS316 cable that runs across the opening without turning it into a caged door — the panel still opens fully, but there's a load-rated barrier in place whenever it does.

10-Year Anti-Rust Guarantee

SS316 Marine Grade Cable

Key Benefits

• Covers the full floor-to-ceiling opening, where regular window grills don't reach
• Panel still opens and closes normally — this isn't a fixed cage over the doorway
• Works as a genuine french window safety grill, engineered for the fall risk specific to full-height openings
• SS316 marine-grade cable, 10-year anti-rust warranty
• 400kg tensile force per strand
• Fits standard casement window grill hardware as well as hinged French panel frames

Technical Features

• Slimline aluminum track fitted to the outer frame, not the door panel itself
• 316 grade stainless steel wire, 2mm–3mm, nylon coated — a transparent window grill in practice, near-invisible from a few feet away
• Fire-emergency cut-capable with a dedicated safety cutter
• Vertical cable spacing consistent across the full door height
• Track finishes in white, dark grey, champagne, and anodized silver

Full cable, coating, and track specifications are the same across all our installations — see Materials & Warranty for the complete spec sheet rather than repeating it here.

Why French Windows Need Different Treatment

A regular window opens a foot or two and sits above the floor line — the fall risk is real but limited. A French window opens its entire height, right down to the floor, which is why french door window grids and grill designs for this window type have to solve for the moment the door is standing open, not just the glass itself. An iron window grill built for this kind of opening either has to be hinged with the door itself, or fixed in place and block the door function entirely — which is why a lot of what's sold as a modern french grill window solution is really just a repurposed door grill that gets in the way of the walk-through use of the opening. French type window grills built on the invisible cable system sidestep that trade-off — the cable spans the opening as a barrier, not a cage, so the space still functions as a door when you want it to.

Installation Steps

1 On-site laser measurement of the full French window opening, floor to lintel
2 Precision drilling into the outer frame, clear of the door panel's swing path
3 Fixing the aluminum track with concealed, weatherproof mounts
4 Strand-by-strand tensioning of the SS316 cables across the full height
5 Final lock-cap seal and load-bearing verification with the door opened and closed

Because the cable has to clear the full swing of the door panel, French window installs are measured and tension-mapped slightly differently from a standard casement window — this is checked during the site visit before any drilling starts.

What Affects French Window Grill Cost in Pune

What Affects the Cost

Every site visit includes a written quote specific to your panel count and height, so you know the exact cost before installation begins.

Panel height

French windows run floor to ceiling, so they use more cable length than a standard window of the same width

Number of panels

a double-panel French window costs more than a single hinged panel

Frame type

wooden vs aluminum vs uPVC frames affect fastener choice

Design finish

standard white/grey track vs champagne or anodized silver

Service FAQs

Will the grill stop my French window from opening fully?

No. The cable spans the frame opening, not the door panel, so the panel swings open exactly as it did before.

Is this different from a regular casement window grill?

Yes. A is built for a window that opens a foot or two; a French window opens its entire height like a door, so the cable run and tension mapping are done differently to cover that full opening safely.

Can I get this in a french window grill design that matches my frame color?

Yes. Track finishes come in white, dark grey, champagne, and anodized silver, so it can be matched to most modern french grill window frame colors during the site visit.

Is it strong enough to stop a fall from a French window left open?

Yes. Each SS316 cable strand is rated to 400kg tensile force, well beyond the force of an accidental push or lean.

Do you install on both single-panel and double-panel French windows?

Yes, both. Panel count changes the cost slightly (more cable length and track for a double panel) but not the installation approach.

How is this different from an SS window invisible grill on a regular window?

The cable and material — SS316, nylon-coated — is the same. The difference is in the measurement and tension mapping, since a French window's opening runs to the floor rather than stopping partway up the wall.

Do you install invisible grills on French windows in high-rise apartments?

Yes — French windows on higher floors face the same wind-load factors we account for in our high-rise installations, so cable tension is adjusted for height in addition to panel size and count.

Is it as safe for children as your balcony grills?

Yes — the same 400kg tensile-rated SS316 cable and tight spacing used on our balcony installations applies here, so a child can't get a foothold or squeeze through even when the panel is fully open.
