The Indian fenestration industry has never been more dynamic. With architecture demanding openness, precision, and durability, the role of windows and doors has shifted from being functional add-ons to becoming defining elements of design. At the centre of this transformation stands GREFET, a brand that has positioned itself as a leader in system aluminium windows and doors, reshaping how buildings perform and how people live inside them.

A System-First Approach
For decades, aluminium windows in India were treated as a sum of parts, frames from one supplier, hardware from another, and assembly often left to improvisation. The result was predictable: inconsistent finishes, poor sealing, and a limited life span.
GREFET chose to address this fragmentation head-on by creating complete systems where every component, profiles, gaskets, hardware, drainage, and locking mechanisms, is engineered to work in harmony.
Key advantages of GREFET’s system-first approach include:
- Predictable performance in all weather conditions
- Longevity and reduced maintenance over the years
- Smooth operation even in heavy-use settings
- Consistency in design and finish across projects
Traditional vs. System Aluminium Windows
To illustrate the shift, here’s how GREFET’s system solutions stand apart from traditional site-assembled aluminium windows:
Feature | Traditional Aluminium Windows | GREFET System Aluminium Windows |
Component Sourcing | Profiles, hardware, and gaskets from multiple vendors | Integrated, engineered as a single tested unit |
Performance | Inconsistent, prone to leakage and rattling | Predictable, tested for water-tightness, air-tightness, wind load, and acoustics. |
Aesthetics | Varying finishes, limited design control | Sleek, uniform finishes with design flexibility |
Durability | Shorter lifespan, premature failures | Long-lasting, tested for extreme conditions |
Fabrication Quality | Depends on local practices | Certified fabricators with modern machinery |
User Experience | Functional but basic | Smooth, quiet, and high-performing systems |
Innovation As The Core

What sets GREFET apart is its commitment to continuous innovation. The brand has consistently invested in developing aluminium systems that not only meet but exceed European performance benchmarks.
Some standout innovations include:
- Large sliding systems that glide effortlessly, even with heavy glass panels
- Slim-profile windows that maximise daylight and views without compromising strength
- Acoustic systems that shield interiors from the chaos of urban environments
- Thermally efficient systems designed to improve energy savings in homes and offices
Crucially, these innovations aren’t reserved for luxury villas or high-end towers. GREFET makes them accessible across residential, commercial, and mixed-use projects, democratising premium fenestration.

Partnering with Fabricators for Excellence
Even the most advanced system can fail if poorly fabricated or installed. Recognising this, GREFET built a network of certified fabricators across India, equipped with:
- Advanced machinery for precision cutting and assembly
- Software-driven design tools for accurate execution
- Training programs that ensure consistency and reliability
This ensures that whether installed in a metro high-rise or a smaller city villa, every GREFET system delivers the same performance promise.
Building Trust Through Performance
Every GREFET system undergoes rigorous testing for:
- Wind load resistance
- Water tightness during monsoon-heavy rains
- Thermal insulation for energy efficiency
- Acoustic comfort for city living
By owning the entire design and testing process, the company confidently assures architects, builders, and homeowners of results they can rely on.

Beyond Products: A Vision for Better Living
At its core, GREFET is not simply producing windows and doors; it is redefining the experience of living with them. By combining aesthetics with durability and engineering with design, GREFET’s systems enable homes and workspaces to feel more open, more comfortable, and more secure.
Conclusion
In an industry still catching up with the demands of modern design and construction, GREFET has established itself as the leader in aluminium windows and doors. With system-based engineering, continuous innovation, and strong partnerships with certified fabricators, GREFET is not just meeting today’s needs; it is setting tomorrow’s standards.
For architects, builders, and homeowners alike, GREFET represents the assurance of quality, the consistency of performance, and the promise of better living, one system at a time.
