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.
