Top Aluminium Windows & Doors Manufacturers in India – ALCOI India

When you think about a home or office that truly feels modern, what comes to mind? For many, it’s not just the décor or furniture, but the way the space feels: bright, open, and seamlessly connected to the outdoors. Windows and doors play a huge role in shaping that experience.

At ALCOI India, we’ve dedicated ourselves to perfecting this balance of design and durability. For us, windows and doors aren’t just architectural elements. They are experiences that frame light, views, and life itself.

Why Aluminium Windows & Doors Are Redefining Indian Homes

The Indian lifestyle has evolved, and so have design needs. Homeowners and architects are moving away from bulky wooden frames or heavy steel, choosing aluminium for its unmatched advantages:

• Strength with Slimness – Aluminium holds expansive glass panels while keeping frames elegant and minimal.
• Climate-Ready Durability – No warping, rotting, or rusting, even in India’s heat, humidity, or monsoons.
• Energy Efficiency – Thermal breaks and insulated glazing keep homes cooler in summer and warmer in winter.
• Minimal Maintenance – A simple clean keeps aluminium frames looking timeless year after year.
• Design Versatility – From matte black to wood-effect finishes, aluminium integrates with every architectural style.

This is why aluminium windows and doors are no longer just a trend — they’ve become the standard for modern Indian living.

The ALCOI India Difference

Founded in 2006, ALCOI has completed 500+ projects with India’s leading architects and developers. With a presence in 25+ cities, factories, Experience Studios, and a growing network of authorised Channel Partners, ALCOI is more than a manufacturer — we are a complete professional package from design to installation and aftercare.

Our design philosophy, inspired by Le Corbusier, focuses on decongesting and enlarging spaces through minimal, elegant frames. Every ALCOI system reflects the principles of Science, Colour, and Craftsmanship.

Here’s what sets us apart:

• System-Engineered: Frames, seals, and hardware designed to work seamlessly together.
• Tested for India: Weatherproof, airtight, and resistant to heat, humidity, and monsoons.
• Safety & Performance: We provide structural safety calculations as per IS 875 Part III, use CAD and STAAD Pro for design and stability analysis, and conduct water hose testing to ensure reliability.
• Health & Safety: Our teams are trained to deliver safe, secure installations with rigorous quality control.
• Customizable: Sliding, casement, tilt-and-turn, folding, pivot, or automated systems tailored to every project.
• Backed by Support: From consultation to project management and aftercare, ALCOI ensures smooth delivery at every step.

Warranty & AMC Support

We believe responsibility extends beyond installation. Every ALCOI system is backed by:

• 10-year warranty on product manufacturing defects and RAL finishes.
• 5-year warranty on wood-effect finishes.
• Glass warranty: No warranty after delivery/installation, unless covered under AMC.
• Annual Maintenance Contracts (AMC):
  • AMC Basic Plus: Preventive & corrective care, inclusive of spares (excludes glass breakage).
  • AMC Basic Plus G: Full coverage including spares and glass breakage.

These service options ensure customers enjoy a pleasant, trouble-free experience for years.
