If you're pricing aluminium windows or doors for a build or renovation, the honest answer to "how much does aluminium cost?" is: it depends on which aluminium you're buying — anywhere from roughly ₹350 to over ₹2,600 per square foot, and the gap between those numbers isn't padding, it's a genuinely different product underneath.
That's the part most price guides skip. A quote from a local fabricator and a quote from a branded "system window" supplier can both say "aluminium sliding window" and land ₹1,500 per square foot apart, because they're describing different alloy grades, different profile depths, different hardware, and different testing standards — not just different margins. If you compare only the number, you'll either overpay for something you didn't need or underpay for something that won't perform.
This guide breaks the market into real price tiers, explains what actually drives the ₹/sq ft number up or down, and flags the costs that tend to get left off the first quote you see.
Key Takeaways
Aluminium windows in India span roughly ₹850–₹3,680 per sq ft installed, split across three broad tiers: local/non-system fabrication, branded standard profiles, and engineered "system window" packages.
The price gap between tiers reflects real differences — alloy grade, profile depth, tested hardware, water/wind ratings — not just brand markup.
Glass, not the frame, is often the biggest swing factor: upgrading to DGU or laminated glass can add ₹150–₹400 per sq ft on its own.
Thermal-break aluminium typically costs 30–40% more than standard aluminium profiles of the same class — worth it primarily for large glazed openings and heat-gain-sensitive rooms.
The per-sq-ft rate on a quote rarely includes everything — installation labour, transport, and accessories commonly add another ₹100–₹230 per sq ft, and GST is usually extra.
What Actually Drives the Price
Before the numbers, it helps to know what you're paying for. The same "aluminium window" can vary on every one of these:
- Alloy grade and profile depth
Higher-grade alloys (6063-T5/T6 and similar) and deeper profile sections (30mm, 35mm, 40mm+ classes) cost more in raw material and machining but deliver more rigidity, better sealing, and longer service life.
- System vs. non-system construction
A "system window" is engineered as a tested stack: profile, gaskets, hardware pockets, and drainage designed together against a defined water and wind rating. A non-system or "local make" window uses compatible-but-unmatched parts assembled on-site, which is cheaper but has no equivalent performance guarantee.
- Glass type and thickness
Clear float glass is the cheapest baseline; toughened, laminated, tinted, and double-glazed units (DGU) all add cost, often more than the frame itself.
- Hardware quality
Rollers, hinges, and multi-point locks from established hardware brands cost more than generic fittings but directly affect how the window performs after year three, not just on installation day.
- Surface finish
Standard powder coating is the cheapest and most common finish; anodizing, PVDF coatings, and wood-effect sublimation finishes cost more.
- Opening size and configuration
Larger openings benefit from some economies of scale per sq ft, but very large spans need reinforcement, heavier hardware, and sometimes motorisation, all of which add cost.
- Installation complexity and location
High-rise access, retrofit work, and site logistics in some cities cost meaningfully more than ground-floor new-construction installs.
Price Tiers: What You'll Actually Pay
Rather than one blended average, it's more useful to think of the Indian aluminium window market as three tiers.
| Tier | Typical Installed Cost (₹/sq ft) | What's Included | Best Suited For |
|---|---|---|---|
| Local / non-system fabrication | ₹550 – ₹750 | Basic alloy sections, standard powder coat, single clear glass, generic hardware, assembled on-site | Budget renovations, rental properties, non-critical openings |
| Unbranded standard profiles | ₹850 – ₹1,200 | Standard profile, standard hardware, choice of basic glass upgrades | Residential projects wanting an entry level aluminium window |
| Engineered "system window" | ₹1,500 – ₹3,680 | Tested profile-gasket-hardware stack, defined water/wind rating, DGU-ready, branded rollers/locks, documentation for architects | Villas, high-rises, coastal sites, large openings, projects where performance has to be verifiable |
These bands overlap deliberately — a well-specified branded window can cost more than a stripped-down system window. The tier tells you what you're generally buying; the specific BOQ (bill of quantities) tells you what you're actually getting, which is why two quotes at the same ₹/sq ft number can still be different products underneath.
Cost by Window and Door Type
Configuration changes the number too, independent of tier:
| Type | Typical ₹/sq ft (before glass/hardware upgrades) | Notes |
|---|---|---|
| Fixed window | ₹850 – ₹1,550 | Cheapest configuration — no moving parts or track hardware |
| Casement window | ₹1,500 – ₹2,850 | Hinges and handles add cost over fixed; good sealing when closed |
| 2-track sliding window/door | ₹1,200 – ₹1,800 | One fixed + one sliding panel; the common balcony/bedroom configuration |
| 3-track sliding window/door | ₹1,500 – ₹5,200 | Costs more in track and rollers but allows a wider clear opening or an added mesh panel |
| Large sliding/folding doors (glass walls) | ₹3,800 – ₹5,600+ | Heavier glass, reinforced tracks, often multi-point or motorised locking; firmly in system-window territory |
Glass: The Cost Driver Hiding in Plain Sight
Homeowners often budget for the frame and treat glass as an afterthought — but glass upgrades routinely move the total more than the frame tier does.
| Glass Upgrade | Typical Added Cost (₹/sq ft, over clear float) | What It Buys You |
|---|---|---|
| Tinted glass | ₹180 – ₹250 | Reduced glare and some solar heat gain, cosmetic tint |
| Thicker toughened glass (8–12mm) | ₹120 – ₹165 | Added strength and safety over standard glass |
| Double Glazed Unit (DGU) | ₹300 – ₹700 | Meaningfully better thermal and acoustic performance |
| Laminated glass | ₹250 – ₹400 | Holds together when shattered — the glass spec that matters most for security and sound |
Combining upgrades — DGU with a laminated inner pane, for instance — stacks these costs rather than averaging them, so a "premium glass" line item on a quote deserves its own scrutiny, not just a glance.
The Thermal-Break Question
Standard aluminium conducts heat readily, which matters in India's climate even though the instinct is to associate thermal breaks with cold-weather markets. A thermal-break profile inserts a polyamide barrier into the frame to interrupt that heat path, and it typically carries a 30–40% premium over standard aluminium of the same profile class.
It's not a default upgrade for every opening. It earns its cost on large glazed areas, west-facing facades, and rooms where cooling load is already a problem — a small bathroom window rarely needs it.
Installation and the Costs That Don't Show Up in ₹/sq ft
The frame price is rarely the full number. Budget separately for:
- Labour
₹50–₹100 per sq ft for measurement, fitting, and sealing.
- Accessories
₹30–₹80 per sq ft for hinges, handles, weather-stripping, and sealants not bundled into the base rate.
- Transport
₹20–₹50 per sq ft, more for difficult access or remote sites.
- GST
Typically quoted separately and added on top — always confirm whether a quoted rate is pre-tax.
Added together, installation commonly adds ₹100–₹230 per sq ft on top of the frame-and-glass number — a gap large enough to meaningfully change a project budget if it's discovered after the fact rather than before.
Aluminium vs. uPVC: The Cost Comparison, Briefly
uPVC and aluminium overlap significantly at the entry level (roughly ₹400–₹1,200/sq ft for both), which is why the material choice shouldn't be decided on upfront price alone. Aluminium's typical 30–50 year lifespan versus uPVC's 20–25 years changes the lifetime-cost picture, especially for large openings where aluminium is usually the only practical choice regardless of price.
We cover this comparison — including where uPVC genuinely wins — in our companion guide, Aluminium vs uPVC vs Wood Windows.
A Quick Checklist Before You Accept a Quote
Does the ₹/sq ft rate include installation, or is that separate?
Is GST included in the quoted number?
What glass thickness and type is the base rate built on?
Is this a "system window" with a documented water/wind rating, or a non-system assembly?
What alloy grade and profile depth is specified — ask for the number, not just "premium aluminium"?
What's the warranty structure, and does it cover the profile, the finish, and the hardware separately?
Frequently Asked Questions
What is the price of aluminium windows per square foot in India?
It ranges from roughly ₹850 per sq ft for basic local fabrication to over ₹3,600 per sq ft for engineered system windows with premium glass and hardware. Most mainstream branded residential projects fall between ₹1,550 and ₹3,200 per sq ft before glass upgrades and installation.
Are aluminium windows more expensive than uPVC in India?
At the entry level, the two overlap substantially — both typically run ₹400–₹1,200 per sq ft. Aluminium's premium end goes higher than uPVC's because system windows, thermal-break profiles, and large spans push the ceiling up; uPVC has a narrower range overall.
Why do aluminium window quotes vary so much between suppliers?
Mainly because "aluminium window" describes very different products: alloy grade, profile depth, whether it's a tested system or on-site assembly, glass spec, and hardware brand all vary — and all move the price independently of the supplier's margin.
Does thermal-break aluminium cost much more than standard aluminium?
Typically 30–40% more than a standard profile of the same class. It's worth specifying for large glazed openings and heat-exposed facades; it's often unnecessary for small, shaded openings.
What is included in an aluminium window's per-sq-ft price — and what isn't?
The frame, standard glass, and basic hardware are usually in the headline rate. Installation labour, transport, upgraded glass, premium hardware, and GST are commonly quoted separately — always ask which of these are included before comparing two numbers.
Is it worth paying more for a "system window" over a local fabricator's aluminium window?
For large openings, coastal or high-rise sites, or anywhere air and water tightness matter, yes — a system window's tested stack and documented ratings reduce the risk of leaks and hardware failure that non-system assemblies can't guarantee. For a small, low-exposure window on a tight budget, a well-made non-system window can be a reasonable trade-off.
Where SCHON Fits Into This
However you shop this decision, the checklist above is the one worth holding any supplier to: a documented alloy grade, a defined profile system rather than an ad-hoc assembly, a clear breakdown of what's in the ₹/sq ft number, and a warranty structure that separates the profile, the finish, and the hardware instead of one vague "warranty" line.
SCHON's systems are built to that standard: profiles carry a 25-year warranty against manufacturing defects, the powder-coat/surface finish is warranted for 20 years against discoloration, and hardware carries a 5-year operational warranty — each tracked separately, not bundled into one number. For openings where heat gain is a real concern, the Infinity 135 platform offers a genuine thermal-break option rather than a standard profile sold as if it solves a problem it doesn't.
