Window frame material — what we default to
Three options. Each suits a different scope.
- Aluminium — most common. Powder-coated finish, lightweight, easy to operate, fits most apartment elevations. Lasts 15+ years with periodic cleaning. The frame profile matters — domeal-grade or section-extruded by recognised manufacturers (Jindal, Hindalco), not unbranded aluminium that thins under pressure.
- UPVC — better thermal and acoustic insulation than aluminium. Right answer for AC-heavy living rooms and for flats facing main roads where road noise is a problem. Brands — Fenesta, Aparna, Eternia, Lingel, Profine. Costs more, lasts longer in coastal humidity.
- Stainless steel grills — for monsoon-facing elevations (Thane West, Manpada, anything west or south-west facing). MS (mild steel) grills painted with enamel rust within 4 to 5 years and need repainting. SS 304 grills do not rust and skip the repaint cycle entirely. Worth the upfront cost on the monsoon-facing side.
Where the Leak Actually Happens — the Flashing
The flashing is the sealing detail at the top edge of the frame, where the frame meets the wall lintel. That gap is where water enters during heavy monsoon if the seal is wrong — and the frame brand on the BOQ won't matter at that point. The honest sequence: a silicone seal around the full frame perimeter, weep holes at the bottom so any water that enters can drain, and an over-flashing strip above the frame to direct water away from the wall-frame joint. Skip the over-flashing, use cheap silicone or leave the weep holes blocked, and the frame leaks within two monsoons. Because the wall-frame junction is a civil detail as much as a window one, it's coordinated with our civil contractor in Thane scope.
Safety Grills — Design and Material
Grill design follows the elevation and the security requirement. Three categories we commonly install: a standard vertical-bar grill (MS or SS, painted or powder-coated, 16–20 mm bar); a decorative grill (laser-cut MS panels in a geometric, floral or contemporary pattern, powder-coated); and a minimal grill (flat MS strap reading as a slim line, for modern elevations). On material: MS painted is the budget option and needs repainting every 4–5 years; MS powder-coated lasts 7–8 years; SS 304 lasts 15+ years and skips the repaint cycle — the honest long-term answer for monsoon-facing Thane West and Manpada flats. The locality scope sits on our window and grill jobs across Thane page.
