If you're building or renovating right now, you've almost certainly run into this decision: aluminium, uPVC, or wood — which one is actually right for your home?
It's one of the most-searched home-improvement questions in India today, and for good reason. uPVC has grown fast in Indian cities over the past few years, aluminium remains the default for larger, more architectural openings, and wood still has its loyalists for a certain kind of traditional home. Every supplier will tell you their material is best. This guide skips the sales pitch and compares all three on the things that actually matter: cost, lifespan, maintenance, thermal and acoustic performance, strength, and environmental impact — with real numbers, not vague claims.
Key Takeaways
uPVC generally wins on upfront cost and out-of-the-box thermal insulation; aluminium wins on strength, lifespan, and design flexibility for large openings; wood wins on natural insulation and classic aesthetics but demands the most upkeep.
Aluminium's one real weakness — heat conduction — is solved with a thermal break profile, which closes most of the gap with uPVC.
Lifetime cost, not upfront cost, is what should drive the decision for most homeowners: aluminium's 30–50 year lifespan often makes it the cheaper option over 20+ years, even at a higher starting price.
The "right" material depends on the opening: a small bedroom window has different priorities than a 12-foot sliding door.
Cost Per Square Foot: What You'll Actually Pay
This is where most homeowners start, so let's start there too.
| Material | Typical Cost (₹ per sq. ft.) | Premium Variants |
|---|---|---|
| uPVC | ₹400 – ₹1,200 | Multi-chamber, colour-laminated profiles at the top end |
| Aluminium | ₹1,400 – ₹2,600 | Thermal-break aluminium systems cost roughly 30–40% more than standard aluminium |
| Wood | ₹2,000 – ₹5,500 | Teak and other premium hardwoods sit at the top of this range; softwoods and engineered wood are cheaper but less durable |
At the entry level, uPVC and aluminium overlap significantly — the gap widens mainly at the premium end, where thermal-break aluminium and multi-chamber uPVC both cost more than their standard versions. Wood's range depends enormously on the species: a basic softwood frame can undercut both, while solid teak can be the most expensive option on this list.
The catch with comparing only upfront cost: it ignores lifespan and maintenance, which is where the real cost difference shows up over 10–20 years.
Lifespan: Which Material Lasts Longest
- uPVC
Typically rated for 7–10 years under normal conditions.
- Aluminium
Commonly rated at 30–50 years, thanks to its inherent corrosion resistance and structural stability — it doesn't rot, warp, swell, or get eaten by termites.
- Wood
Can last decades or more, but only with consistent, disciplined maintenance. Without it, humidity, termites, and monsoon exposure can significantly shorten its usable life in most Indian climates.
Run the numbers over a 30-year horizon and aluminium's higher upfront cost often evens out or comes out ahead, since you're not paying for a full replacement partway through — a cost most upfront comparisons leave out entirely.
Maintenance: What Each Material Actually Needs
- uPVC
Low maintenance. It doesn't rust or rot and generally just needs periodic cleaning. It's a genuinely strong selling point for uPVC and one reason it's grown so quickly in Indian cities.
- Aluminium
Also low maintenance when properly finished (powder-coated or anodized). It won't rust, and a wipe-down is usually sufficient. Be sure to choose premium aluminium systems from a great company like Schon and your finish and fit will last decades.
- Wood
The highest maintenance of the three. Left untreated, wood is vulnerable to termites, rot, and warping — a real risk during the Indian monsoon. Keeping it in good condition usually means refinishing, sealing, or repainting every couple of years.
If low maintenance is your priority, wood is the hardest of the three to justify unless you're genuinely prepared for the upkeep — or specifically want the aesthetic it offers.
Thermal Performance: Keeping the Indian Heat Out
This is the one category where the "aluminium is the strongest, so it must be best" instinct breaks down.
- uPVC
Has naturally low thermal conductivity and a multi-chambered profile, so it insulates well straight out of the box — no upgrade needed.
- Aluminium
Multi Void Aluminium profiles offer excellent heat insulation, coupled with DGU glass it will be a great insulator for heat. Thermal-break aluminium changes the picture: a polyamide barrier is inserted into the profile to interrupt the metal's heat path.
- Wood
A naturally good insulator, which is part of why it still has a following despite the upkeep.
If you're specifying aluminium for a hot climate, thermal-break is the detail that decides whether you get uPVC-like insulation or pay a comfort (and cooling-bill) penalty for choosing it.
Acoustic Performance: Blocking Noise
Frame material plays a secondary role here compared to glass. uPVC's airtight, welded-corner construction gives it a natural edge for sealing out noise, but for all three materials, the glass specification — specifically a double-glazed unit (DGU) with an appropriate air gap — matters more than the frame. A well-sealed aluminium or wood window with DGU glass can match or beat a uPVC window with single glazing.
In short: don't choose your frame material for acoustic performance alone — choose your glass.
Strength, Security & Design Flexibility
This is aluminium's clearest advantage.
- Aluminium
Aluminium's strength-to-weight ratio allows for slimmer frames, larger glass spans, and heavier sliding or folding doors than uPVC or wood can comfortably support. If you want a 10–12 foot sliding wall of glass, tall French windows, or a nearly frameless look, aluminium is generally the only practical choice among the three.
- uPVC
A strong material for standard-sized windows and doors but is bulkier by design (the multi-chamber profile that helps insulation also adds visual weight) and has practical limits on size and load for very large openings.
- Wood
Can be structurally capable but becomes heavy and expensive at large sizes, and its dimensional stability under humidity limits how large a single sash can reliably be before warping becomes a risk.
On security specifically, all three can be built to a high standard with the right glass and locking hardware — the frame material itself is a smaller factor here than glass type and lock quality.
Environmental Impact
- Aluminium
Is 100% and infinitely recyclable without loss of quality — a genuinely strong sustainability credential, offsetting the higher energy cost of primary production.
- uPVC
Is a PVC-based plastic; it's durable and long-lasting, but recycling infrastructure for PVC window profiles is far less mature than for aluminium, and it's not biodegradable.
- Wood
Is renewable if responsibly sourced (look for FSC-certified timber) but carries a real environmental cost when it isn't — deforestation and unsustainable logging remain genuine concerns for uncertified sourcing.

Which Material Is Right for Your Home?
- Standard bedroom or kitchen windows on a tight budget: uPVC is a reasonable, low-maintenance choice.
- Large sliding doors, glass walls, or wide openings: Aluminium is generally the only material of the three that comfortably handles the span and weight.
- A hot climate and a large aluminium opening: Specify thermal-break aluminium — don't default to standard profile and accept the heat-gain penalty.
- A traditional or heritage-style home where the look matters most: Wood remains the strongest aesthetic choice, provided you're genuinely willing to maintain it.
- A coastal or high-humidity property: Aluminium — to resist the corrosion and rot risk that humidity creates for untreated wood.
Frequently Asked Questions
Is aluminium or uPVC better for Indian homes?
Neither is universally "better" — it depends on the opening and priority. uPVC tends to win on upfront cost and out-of-the-box thermal insulation for standard-sized windows. Aluminium tends to win on strength, lifespan, and design flexibility, especially for large sliding doors and glass walls, and closes the thermal gap with a thermal-break profile.
Does aluminium get hot in Indian summers?
Standard aluminium does conduct heat more than uPVC or wood. A thermal-break aluminium profile — which inserts an insulating barrier into the frame — largely solves this and is the recommended specification for hot climates.
Is uPVC actually cheaper than aluminium in the long run?
Not always. uPVC is usually cheaper upfront, but aluminium's longer lifespan (30–50 years vs. 20–25 for uPVC) can make the lifetime cost comparable or even favour aluminium, especially if a uPVC installation needs replacing while an equivalent aluminium one is still going strong.
Which is more durable in the monsoon: aluminium, uPVC, or wood?
Aluminium and uPVC both handle monsoon humidity well since neither rusts, rots, nor attracts termites. Wood is the most vulnerable of the three unless it's properly treated, sealed, and consistently maintained.
Can aluminium windows be as energy-efficient as uPVC?
Yes, with a thermal-break profile. Standard (non-thermal-break) aluminium is the weaker insulator of the two; thermal-break aluminium closes most of that gap while retaining aluminium's strength and design advantages.
Which material is best for large sliding doors or glass walls?
Aluminium, by a clear margin. Its strength-to-weight ratio supports larger spans, heavier glass, and slimmer sightlines than uPVC or wood can typically achieve at the same scale.
Where SCHON Fits Into This
We make aluminium systems, so it's fair to expect some bias here — which is exactly why the comparison above gives uPVC and wood full credit where they earn it. If your project is a handful of standard-sized windows on a tight budget, uPVC is a perfectly reasonable choice, and we'd say so to any homeowner who asked.
Where aluminium is the clear right answer — large sliding doors, glass walls, tall French windows, or any opening where strength and slim sightlines matter — SCHON's systems are built to close aluminium's one real weakness rather than ignore it: our Infinity 135 platform offers a genuine thermal break option for climates where heat gain matters, every system carries a 25-year profile warranty backed by in-house manufacturing, and finishes range from powder coating to anodizing, PVDF, and wood-effect sublimation for the aesthetic wood buyers often want without the maintenance wood requires.
