When you get a quote for uPVC windows in Coimbatore, it usually comes as one number per window. That's fine for comparing, but it hides where the cost actually goes — which makes it hard to know what you're paying for and what you might reasonably negotiate. Here's an honest breakdown of where rupees go in a uPVC window. We're a Coimbatore manufacturer, so these proportions reflect actual factory costs rather than dealer markups. The big four are profile, glass, hardware, and labour — in roughly that order.
A typical uPVC sliding window costs roughly: profile 35%, glass 25%, hardware 15%, fabrication labour 10%, installation 8%, transport and overhead 7%. So for a ₹20,000 window: ₹7,000 profile, ₹5,000 glass, ₹3,000 hardware, ₹2,000 fabrication, ₹1,600 installation, ₹1,400 overhead. These proportions shift if you change spec — double-glazing pushes glass up to 40%+, performance hardware can take its share to 25%. Dealer-sold windows add 15-25% on top for the dealer margin, which is part of why factory-direct is competitive even though we're not the cheapest in absolute terms.
Profile cost is genuinely higher — uPVC is a thicker, more engineered extrusion. Glass and hardware are comparable. The full-life cost favours uPVC because it doesn't pit, conduct heat, or need repainting, but the day-one price is higher.
It's a useful rough planning figure but it isn't how we quote. We quote per actual window because a 3ft × 3ft window and a 6ft × 6ft window don't cost 4× different even though their area does — fixed costs (hardware, fabrication labour, installation visit) don't scale linearly with size.
Fabrication labour and overhead, in absolute rupees. The 'expensive' parts are profile and glass because those are material costs we can't compress. This is why volume orders (whole-home replacement) get small per-unit savings — fixed costs spread across more units.
Possible but risky. Profile makers won't usually sell to end customers, only to licensed fabricators. And even if you got it, the savings are usually 10-15%, while quality risk is much higher — fabrication is where most failures start.
Yes — roughly 35-50% more per window for double-glazed vs single. That extra cost is mostly the second pane of glass and the insulating spacer. Worth it for bedrooms on noisy roads, often not worth it for kitchens or bathrooms.
