I got Upvc windows done from them and also aluminium partition in bathroom . The quality of their work is very good and dealing with clients is exceptional . Specially mentioning Priyanka and Sharma ji who is excellent in dealing with clients. The prices are value for money in upvc but their Aluminium work is more than the market prices . May be BCOS of economies in Aluminium and that of their major business of Upvc. I am satisfied with their services . Will recommend them for UPVC work for sure

Casement windows open outward on hinges, offering maximum ventilation, a tight weatherproof seal, and unobstructed sightlines — making them one of the most practical and popular window styles for both residential and commercial spaces across Delhi and NCR. Our aluminium profiles are built to withstand scorching Delhi summers, heavy monsoon rains, and dry winter winds without warping, rusting, or fading. Every unit goes through rigorous quality checks aligned with international fenestration standards before it leaves our facility. Whether you are upgrading a single room or outfitting an entire building, Stay Bright Window gives you windows that perform on every measure — strength, insulation, aesthetics, and longevity.

No.1 & Leading Aluminium Casement Windows Manufacturers & Suppliers Since 2009 — Stay Bright Window
Since 2009, Stay Bright Window has manufactured and supplied over 1 million square feet of premium fenestration solutions across India, and our Aluminium Casement Windows remain among our most requested products. What sets our casement windows apart starts at the profile level — our aluminium frames use a multi-chambered design that delivers superior thermal insulation, significantly cutting down air conditioning costs in warm Delhi summers. The frames are powder-coated in a wide range of RAL colours, so you get a finish that resists chipping, UV degradation, and corrosion for decades with virtually zero maintenance. We fit every unit with high-grade multi-point locking hardware that strengthens burglar resistance far beyond what standard single-latch windows offer. Our glazing options include single glass, double-glazed units (DGU), and laminated safety glass — each chosen based on your noise reduction needs, thermal goals, and security requirements. As experienced Aluminium Casement Windows dealers and suppliers serving Delhi, NCR, and customers across India, we also support full customisation — frame dimensions, glass type, colour, mesh integration, and ventilator configurations all adapt to your exact architectural drawings. Our in-house team of customer relationship managers works with you from measurement to final installation, eliminating guesswork at every stage and ensuring the finished product matches your vision precisely.

Choosing an Aluminium Casement Window
An aluminium casement window opens on side hinges like a small door, so the whole sash swings clear and the room gets its full opening for air. Buyers searching for aluminum casement windows usually want two things from this style: a tight seal when shut and a frame slim enough to keep the glass area large. Both come from the profile itself. A thermally broken aluminium section keeps the inner face from turning hot in May, and compressed EPDM gaskets close the gap between sash and frame when the handle is locked.
For wide openings we pair a hinged sash with a fixed light beside it, which keeps the moving part light and the hardware under less strain. Tell us the wall opening, the floor and the direction of the wind, and we will size the sash and hinge accordingly.
