Griham is reimagining homes and commercial spaces across India with its world-class technology, cost-efficiency and exceptional service standards. Our mission is clear, to deliver world-class, value-driven uPVC windows and doors solutions that enrich everyday life without compromising on the aspirations of our stakeholders.
When we say System Window, we mean that quality is not accidental or dependent on individuals. It is engineered, measured, tested, and controlled at every single stage — from raw material selection to long-term performance in your home.
A system window is not just a window product. It is a complete, integrated solution where one company defines standards, controls execution, and takes full responsibility for performance.
The foundation we begin by selecting and formulating high-quality uPVC resin designed for Indian climatic conditions. The right resin formulation ensures resistance to heat, UV radiation, weathering, and ageing, which directly impacts the life and colour stability of the window.
Precision manufacturing profiles are extruded in a controlled factory environment using precise parameters for wall thickness, multi-chamber design, and dimensional accuracy. Continuous quality checks ensure consistency across batches.
Reinforcement strength where needed every window design is engineered for size, wind load, and usage conditions. Reinforcements are calculated, not guessed, ensuring structural strength, no sagging, and smooth operation over years.
Accuracy, not approximation fabrication follows strict system standards using European machines for cutting and welding. This ensures perfect alignment, rigid frames, strong joints, and superior sealing performance.
Matched to the system hardware is selected based on window size, weight, and load requirements. Multi-point locking systems and compatible hardware ensure safety, durability, and smooth functionality.
Performance focused glass is chosen based on performance needs, not just thickness. Factors such as noise reduction, thermal comfort, safety, and wind load are considered while selecting single, double, or laminated glass.
Proven, not claimed system windows are designed to meet defined benchmarks for wind load resistance, air permeability, and water tightness. These parameters ensure real-world performance during storms, dust conditions, and heavy rainfall.
The final and critical step trained installation teams follow standard fixing and sealing methods. Proper installation ensures the window performs exactly as engineered, without leakage, misalignment, or premature failure.
Because quality and standards are controlled at every stage, you receive a window that delivers consistent performance, lower maintenance, better comfort, and long-term peace of mind.
A system window may cost more upfront, but it eliminates uncertainty and reduces lifetime costs, making it the most dependable choice over 20–25 years.
Every Griham door and window comes with guaranteed Iron reinforcement inside for superior strength, stability and long life.
In simple terms:
A system window is built the right way — at every step, without
compromise.

Gold Line Doors & Window
In India, this is being introduced for the first time, setting a new benchmark in the uPVC window industry. It offers homeowners and architects a unique opportunity to elevate their spaces with a touch of opulence
What is Gold Lining in uPVC?
It is a metallic gold-coloured strip, Architectural groove in Upvc Profile. It usually runs along the beading (the strip holding the glass), the frame edge, or as a mullion (divider) within the glass itself.
Advantages
Co Extruded gasket
A co-extruded gasket is a high-performance weather seal that is manufactured simultaneously with the uPVC profile. Unlike traditional rubber seals that are manually rolled or pushed into place after the frame is built, co-extruded gaskets are permanently fused to the uPVC profile during the actual extrusion process.
This seamless integration creates an airtight, watertight barrier that elevates the performance and durability of your windows and doors.

Griham gets its name from the Sanskrit word Grih, which means home. A home is not just a building, it is where a family belongs, and it is usually built with years of savings and hard work. That is why Griham was never meant to be just a product. Our aim is simple: to create secure and sustainable, modern living spaces that families can trust for generations.
Griham is backed by The Supreme Industries Limited, a name India has trusted since 1942. We handle every stage ourselves - design consultation, system engineering, manufacturing, fabrication, installation and after-sales service. We work on five values: trust, innovation, flexibility, ownership and equality.
Griham offers system doors and windows which make your house or establishment look contemporary while providing smooth and robust functionality. We handle the whole chain ourselves: surveying your site, designing the profile, extruding it, fabricating, performance-testing, delivering, installing and servicing it. One name, one standard, one company answerable for the result. Every frame also carries guaranteed iron reinforcement inside.
That is what a system brand means. Quality is engineered, measured and controlled at every stage. Among uPVC doors and windows manufacturers in India, this level of end-to-end control is rare.
Indian weather is hard on a home. Summer afternoons cross 45°C, the monsoon brings rain that comes in sideways, coastal air carries salt, cities carry dust, and traffic noise runs through the day and most of the night. A window has to handle all of this, year after year. That is why uPVC doors and windows have to be built for Indian conditions from the start . Our profile is formulated for exactly these conditions and UV-stabilised against yellowing and brittleness. Four-chamber structure with iron reinforcement, co-extruded gaskets, fusion-welded joints and dust proof and thermal insulation keep water, dust and heat outside. Our uPVC windows and doors deliver excellent sound and thermal insulation. They reduce external noise by up to 40 dB, and give energy saving upto 30%. With European Technology and Indian Craft, Supreme builds windows and doors that are made for Indian conditions, so they stay quiet, sealed and steady for years.
Three things set Griham apart from what Indian buyers usually get in a door or window design.
DecoShield is surface engineering. It brings a natural-looking texture that adds depth. This gives you a chance to choose textures like wood grain, stone, marble or any other designer finishes. This is what Griham means by "Not just colours, Feel the texture." The surface engineering technology also brings in long-lasting colour stability, a UV-resistant coating to prevent fading, peeling or discolouration, and scratch-resistant surfaces, ideal for Indian conditions.
Smart Home Concepts bring keyless entry, fingerprint, PIN and app control to uPVC door styles that once ended at a handle. This is security you operate from your phone.
Gold Line adds a precision architectural groove finished in anti-tarnish metallic gold along the bead, frame edge or mullion, elevating traditional and minimalist windows and doors alike.
Together they turn designs for windows and doors from a specification into a design decision, to make it feel genuinely yours.
Griham is built on purpose. Homeowners get uPVC doors and windows that stay quiet, cool and clean with nothing more than a wipe. Architects get a system that holds spans, sightlines and tolerances exactly as drawn. Interior designers get finishes and colours matched to a scheme, not a catalogue. Builders get uPVC windows and doors delivered on schedule and at scale, with zero-defect fitment. And lastly, commercial developers get tested performance, BIS compliance, a 20-year profile warranty and a 10-year hardware warranty, they can put in a spec sheet. Whether you need one balcony slider or multiple openings, the best uPVC windows in India should serve every scale, and that is exactly what you get, thanks to Griham's system doors and windows.
Behind Griham stands The Supreme Industries Limited, incorporated in 1942, with 83+ years of polymer leadership, over ₹11,000 crore turnover, 35+ plants, and 6,500+ dealers and distributors backed by a strong network of partners nationwide.

Griham manufacturing is spread across a 34-acre facility, the industry's largest, and its first double-storey plant with extrusion and fabrication under one roof. Industry 4.0 automation and AI-driven quality control deliver customisation at scale.
