Once seen as purely functional, windows and doors have now evolved into defining elements of modern architecture. Today, they represent a fusion of aesthetics and performance — from high sound insulation and weather resistance to sleek, minimalist designs. At the forefront of this transformation is Qwind, offering advanced window and door systems that align with global standards, backed by state-of-the-art R&D and the trusted legacy of the Nilkanth Group.

Qwind – Pioneers in Window & Door Innovations

Qwind brings over three decades of industry legacy from Morbi, Gujarat. As a one-stop solution for the design, production, and installation of aluminum system windows and doors, Qwind combines state-of-the-art technology with timeless design. Our focus on efficiency, durability, and global standards is matched by a commitment to loyal service and innovation. At Qwind, excellence is not just delivered — it’s built into every product. Our guiding principles? Flawless. Timeless.

Materials That Make the Difference

Aluminum: Strong, Lightweight, and Sleek

Qwind frames are manufactured using 6063 aluminum alloy, known for its durability and optimal performance in system windows and doors. This material supports slim profiles without compromising on structural strength, enabling modern aesthetics and long-term reliability.

Stainless Steel Grills: Safety with Elegance

In Qwind’s grilled series, safety is reinforced using 16mm MS round bars. These integrated safety grills are designed to offer strong physical protection while seamlessly blending with the overall window and door design — delivering both security and visual appeal.

Glass Types: From DGU to Burglar Resistant

Qwind systems are compatible with multiple types of high-performance glass, including:

DGU (Double Glazed Units)

DGU Laminated and Sentry Laminated Glass

Reflective and Low-E Glass

Burglar-Resistant Glass Options

These glazing combinations provide sound reduction of up to 38 dB, enhancing acoustic comfort across Qwind’s sliding, casement, and minimal series.

Top Trends in Window Design

Minimalist Slim Profiles – SL Series

Qwind’s Slender Series — including SL-19, SL-21, and SL-33 — emphasizes ultra-slim profiles for modern architectural aesthetics. These models feature sight lines as narrow as 19mm (SL-19) and up to 33mm (SL-33), making them ideal for creating seamless transitions between indoor and outdoor spaces.

Sound Insulation – Live Quietly

The SL series supports various glass types such as DGU, laminated, and sentry laminated glass, offering sound reduction up to 38 dB (SL-19). These windows are designed with features like perforations, argon gas insulation, and auto-clean brushes, ensuring enhanced acoustic comfort in noisy environments.

Invisible Sight Lines for Aesthetic Appeal

Models like SL-19 Invisible come with hidden bottom frames, concealed tracks, and minimal interlocks, allowing the window system to blend into the wall. Combined with anodized, powder-coated, or wood-effect finishes, this makes for a clean and contemporary visual profile — minimal yet sophisticated.

Latest in Door Design

Casement Doors with Integrated Blinds

The QDS-70 casement door system supports glass thickness from 30mm to 46mm, including laminate, DGU, and DGU laminate options with integrated blinds. This allows for enhanced privacy, light control, and a clean, modern aesthetic — all within a high-performance system that offers up to 32 dB sound reduction.

Folding Doors for Wider Openings

The QDS-70 FD (Folding Door) model enables wide openings and smooth spatial transitions. Built with 6063 aluminum alloy and 304-grade stainless steel rails, it supports glass thicknesses from 8mm to 30mm and is engineered for easy operation with multi-locking systems and retractable mosquito mesh.

Curtain Wall Systems for Luxurious Spaces

Qwind’s SD-40 Facade Series provides an elegant curtain wall solution. Designed for glass up to 44mm thick and sound reduction up to 38 dB, it supports various opening types like turn & tilt, side-hung, and top-hung. Despite the sleek look, it maintains performance with options for steel reinforcement to withstand high wind loads.

Security First – Grilled Window Series

Built-in Safety Grill Options

Qwind offers dedicated grilled window models such as SL-25 Grilled, SL-26 Grilled, SL-21 Grilled, and SL-30 Grilled. These are part of the Sliding Grilled Series, where safety grills are seamlessly integrated within the window frame design to ensure enhanced security without disrupting the aesthetics.

16mm MS Round Bar Grills

Each of these grilled models includes a safety grill made from 16mm MS (mild steel) round bars, providing a strong physical barrier while maintaining visual harmony with the window system.

Multi-Locking Systems

The grilled window systems — along with many non-grilled ones — come equipped with multi-locking mechanisms, delivering reinforced security by locking the sash at multiple points. This ensures added protection against forced entry while maintaining smooth functionality.

Functional Elegance – Features That Matter

Auto Clean Brushes

Qwind window systems feature auto-clean brushes placed between the bearing cages at the bottom of the shutter. These brushes help remove dust that accumulates in the corners of the track, maintaining smooth operation and minimizing the need for manual cleaning.

Argon Gas for Thermal Insulation

Within the DGU (Double Glazed Unit), Qwind uses argon gas filling between the glass layers. This significantly reduces thermal conductance, improving insulation performance and enhancing indoor comfort by minimizing heat transfer.

Hidden Bottom Frames for Clean Looks

Select models such as SL-19 Invisible offer a hidden or fully concealed bottom frame, providing a seamless and elegant appearance. This design feature helps the window integrate effortlessly into the architecture, contributing to a clean and modern aesthetic.

Performance Under Pressure

Qwind’s window and door systems are engineered to handle tough weather conditions without compromising performance.

Wind Resistance: Systems like the SL-19 and SL-19 Invisible are tested to withstand wind pressures of up to 3 KPa, ensuring structural stability even in high-wind zones.

Air Infiltration: Designed for efficiency, these systems limit air leakage to 300 Pa, helping maintain interior temperature control and energy efficiency.

Water Penetration: With a water resistance rating of 390 Pa, Qwind profiles offer strong protection against rainwater seepage — an essential feature for regions with heavy monsoon conditions.

Customization Options

Finishes – Anodized, Powder Coated, Wood Effect

Qwind systems are available in a variety of surface finishes including anodized, powder-coated, wood effect, and PVDF coating. These finishing options allow customers to match the window or door design with their interior or exterior style preferences — whether it’s a sleek matte, a rich wood texture, or a vibrant architectural finish.

Mosquito Mesh Integration

Multiple Qwind models come with integrated mosquito mesh solutions, including retractable or roll-down mesh options. These are designed to fit smoothly within the window or door frame, offering insect protection without affecting design or usability.

Corner Opening Windows

Select systems such as the SL-19 include corner opening capabilities, which enable larger, more open views and improved ventilation. This feature enhances openness in architectural layouts where extended sight lines and airflow are priorities.

Sustainability and Low Maintenance

Recyclable Materials

Qwind manufactures its window and door systems using 6063 aluminum alloy and 304-grade stainless steel, both of which are fully recyclable. This supports long-term sustainability goals while maintaining structural integrity and performance.

Eco-Safe Powder Coatings

The finishes available on Qwind systems — including anodizing, powder coating, wood effect, and PVDF coating — are applied using processes that align with environmental protection standards.

Near-Zero Maintenance

Thanks to features like auto-clean brushes, corrosion-resistant materials, and sealed frame designs, Qwind products require minimal upkeep. These systems are engineered for long-term durability, even in challenging weather conditions.
