Aluminium Window Price List by Type (Per Square Foot)

The design and opening mechanism are the first major cost differentiators. The complexity of hardware and the amount of specialized profile required vary significantly between types.

The following prices are approximate market rates in the Delhi NCR for supply and fabrication (excluding installation and GST, unless noted), assuming standard 5mm clear glass and basic powder-coated profiles.

Window & Door Price Table (Base Cost)

Product Type	Profile Quality	Estimated Price Range (₹/sq. ft.)	Key Use Case
Aluminium Fixed Windows	Standard/Domal Section	₹250 – ₹450	Areas needing light/view, no ventilation (e.g., stairwells, high walls).
Aluminium Sliding Windows (2-Track)	Standard Domal/Euro Series	₹300 – ₹600	General residential, balcony separation (space-saving operation).
Aluminium Sliding Windows (3-Track)	Medium-Duty Profile	₹450 – ₹750	Requires Mosquito Mesh, maximizing ventilation area.
Aluminium Casement (Hinged) Window	Medium-Duty Profile	₹500 – ₹900	Maximum airtightness, superior dust/noise control (multi-point locking).
Basic Aluminium Doors (Single/Double Shutters)	Standard Domal Section	₹350 – ₹650	Bathrooms, utility rooms, and internal cabins.
Premium Lift & Slide Doors	Heavy-Duty System	₹1,200 – ₹2,500+	Large terrace openings, expansive views (high-end architectural system).

2. Critical Cost Factor: The Aluminium Profile & Glazing

This is where the difference between a budget window and a high-performance system truly lies.

A. Frame Profile: The Core Cost Driver

The cost of aluminium window fabrication is highly dependent on the frame section used, often measured by weight (per running meter or kg).

Profile Type	Description	Price Impact	Performance for Delhi
Domal/Standard Section	Thin walls, minimal chambers. Lightweight (approx. 0.7 - 1.2 kg/m).	Low Cost	Low insulation, poor sealing, susceptible to flex.
Euro/Medium Section	Thicker walls, dedicated tracks for hardware and seals.	Medium Cost	Good durability, moderate sealing, standard for casement systems.
Heavy-Duty/System Profiles	Thick, multi-chambered, engineered for large spans (2.0+ kg/m).	High Cost	Superior structural strength, excellent sealing, necessary for high-rise.
Thermal Break Profile	Polyamide strip separating the interior and exterior aluminium (most complex).	Premium Cost (2x to 3x)	Essential for Energy Efficiency in Delhi; prevents heat/cold transfer.

B. Glazing Type: Your Barrier Against Noise and Heat

The glass alone can account for 40-50% of the total unit price. For the extreme Delhi climate, plain glass is inadequate.

Glazing Type	Description	Price Impact (vs. 5mm Clear)	Performance Benefit in Delhi
5mm/6mm Toughened Glass	Single pane, chemically treated for safety and strength.	1.0x to 1.5x	Essential safety for doors/low-level windows.
Double Glazed Unit (DGU)	Two panes separated by a dry air/gas cavity (5-12-5 mm).	2.5x to 3.5x	High thermal insulation, significant noise reduction.
Laminated Glass	Two panes bonded by a PVB interlayer.	2.0x to 3.0x	High acoustic insulation (soundproofing) and extreme security.
Low-E Glass	Special coating reflects solar heat.	Added 15% – 30% to the DGU cost.	Reduces heat gain, lowering AC costs drastically in summer.

3. Hardware, Finish, and Accessories Costs

The accessories determine the window's functionality, security, and long-term maintenance needs.

Component	Cost Impact	Details
Standard Powder Coating	Included in Base Price	The common, durable finish; offers protection against corrosion.
Premium Finish (Anodized/Textured)	Added 15% – 30%	Superior depth of color, enhanced UV and abrasion resistance.
Rollers/Wheels	Critical (Don't Compromise)	Standard plastic rollers are cheap. Stainless steel/Teflon-coated rollers are essential for smooth operation and durability in heavy sliding systems.
Multi-Point Locks	Added 10% – 20%	Essential for casement windows and doors; provides superior security and an airtight seal against dust/rain.
Mosquito Mesh	₹80 – ₹180/sq. ft.	Cost for the mesh material (fiberglass/SS) plus the separate slim aluminium frame required to hold it.
EPDM Gaskets	Included (But Varies in Quality)	High-quality EPDM rubber seals are critical for dust and soundproofing. Cheaper systems use inferior, fast-degrading PVC seals.

4. Fabrication Cost Factors: AluTown’s Checklist

When requesting a final quotation, these factors move the aluminium door cost up or down:

• Size & Shape: Very large or highly customized shapes (arches, curves) require more complex fabrication pricing and labor, increasing costs per square foot.

• Order Volume: Larger projects with standard dimensions will attract better rates due to material bulk-buying and fabrication efficiency.

• Supplier's Reputation: Established fabricators like Shri Krishna Aluminium (AluTown) typically have higher rates than small roadside vendors, but they guarantee standardized profile quality, certified welding, and warranty, justifying the higher investment.

• Accessibility: Complex designs, particularly bi-fold or lift-and-slide doors, have higher fabrication labor costs due to the precision required for the specialized hardware.

5. GST and Installation Charges (The Final Costs)

These charges are often overlooked in initial budgeting but are necessary to calculate the final, project-ready price.

H3: GST Rate on Aluminium Windows & Doors (2025 Update)

As per the latest updates to the GST Council's rates, the supply and installation of aluminium windows and doors are now generally treated under the "Works Contract Service" category or specific structural aluminium HSN codes.

• Applicable GST Rate: 18%

  • Note: This rate is applicable to the final billed amount, which includes the cost of material, fabrication, and installation labor. Always confirm the HSN code and rate with your fabricator's finance team.

Installation Charges in Delhi NCR

Installation is a critical service, not just a fitting charge. A poor installation will negate the benefits of the most expensive window.

Installation Factor	Impact on Cost (₹/Unit or % of Total Cost)
Standard Installation (Ground/First Floor)	Included in the final quoted price (or ₹500 – ₹1,000 per unit)
High-Rise/Complex Installation	Added 5% – 15% to the Total Cost
Removal of Old Frames (Debris Disposal)	₹500 – ₹1,500 per frame
Scaffolding/Safety Charges	Applied for heights above 3rd floor (billed separately by external vendor)
Chemical Grouting/Sealing	Varies; high-quality sealants add to the material cost (₹50-₹100/ft of perimeter)

Practical Buyer Tips from AluTown Experts

To ensure you get the best value for your aluminium door cost and window investment in the Delhi NCR:

1. Prioritize Thermal Break: If your home uses air conditioning for more than 4 months of the year, the extra cost of a Thermal Break system will be recovered quickly through energy savings.

2. Measure Twice, Quote Once: Insist on a professional site measurement by the fabricator. Don’t rely on builder drawings, as small wall deviations can affect the final quote and fit.

3. Inspect the Profile Thickness: Always ask to see the sample profiles and confirm the milligram weight per running meter (e.g., a "heavy-duty" profile should be 2.0+ kg/m). Thicker profiles ensure stability and better screw retention for the hardware.

4. Confirm the Hardware Brand: Ask for branded, multi-point locking mechanisms and stainless steel rollers. Hardware is the most frequent point of failure in cheap systems.

5. Demand an All-Inclusive Quote: Ensure the final quotation clearly separates the Frame, Glass, Hardware, GST, and Installation charges. A single, low aluminium window price Delhi 2025 is often achieved by hiding substandard components or later adding installation/GST charges.

Frequently Asked Questions (FAQs)

Q1: Why is a casement window more expensive than a sliding window of the same size?

A: Casement windows require more complex and expensive hardware, including high-grade hinges and a multi-point locking system for compression sealing. Sliding windows use simpler rollers and brush/wool pile seals, which are less expensive to fabricate.

Q2: How does DGU affect the final window price?

A: DGU (Double Glazed Units) can increase the overall window unit cost by 2.5 to 3.5 times compared to single glass. This is due to the cost of two panes of glass, the spacer bar, the sealant, and the complexity of installation, but it provides a massive return in energy savings.

Q3: What is the minimum thickness I should look for in residential aluminium windows?

A: For basic residential use, a standard series profile with a wall thickness of at least 1.2mm is acceptable. For high-performance, large-span, or thermal break windows, the profiles should be substantially heavier, often with wall thicknesses between 1.6mm to 2.0mm or more.
