uPVC Casement Windows – Full-Opening Hinged Windows for Maximum Ventilation

A uPVC casement window is a hinged window that opens outward or inward from the side, allowing the entire panel to swing fully open for maximum ventilation. This makes casement windows one of the most efficient window solutions for bedrooms, kitchens, and spaces where airflow is essential.

FabFrame by Atul Glass manufactures high-performance uPVC casement windows designed to deliver superior weather sealing, smooth operation, and long-term structural durability for residential homes, villas, and commercial properties across North India.

Unlike sliding windows, which open only partially, casement windows provide full opening along the entire panel height, ensuring better air circulation and natural ventilation. FabFrame offers uPVC casement windows in side-hung single, side-hung double, and top-hung configurations, all precision-engineered using multi-chambered uPVC profiles, galvanized steel reinforcement, and advanced espagnolette locking systems.

Whether you are installing windows for a bedroom, a kitchen, or a villa in a hilly region, our casement window systems are built to perform reliably in all North Indian climate conditions. You can also explore our complete uPVC Solutions range to compare different window types and select the right system for your space.

Advantages of uPVC Casement Windows

Maximum Ventilation Through Full Opening — Because the entire sash swings clear of the frame, casement windows allow the full panel area to ventilate — significantly more effective than sliding windows of the same size, which open only half the panel width. This makes uPVC casement windows the preferred choice for bedrooms, study rooms, and any space where natural air circulation is a daily comfort requirement.
Superior Multi-Point Weather Sealing — A three-layer EPDM rubber gasket system compresses firmly against all four sides of the frame when the casement is closed, creating an airtight barrier against wind-driven rain, dust, and cold air. This level of sealing is superior to sliding window brush seals — making casement windows especially well-suited for hill properties in Himachal Pradesh and Uttarakhand, where monsoon and snowfall exposure is high.
Precise Ventilation Control via Friction Stays — Adjustable friction stay bars or hinge restrictors hold the window open at any angle without requiring the user to hold it in position. This allows precise airflow management — partially open for a light breeze, fully open for maximum circulation — making casement windows practical for daily use in all seasons.
Multi-Point Espagnolette Locking for Security — A single handle rotation activates locking points simultaneously at multiple positions around the sash perimeter. This creates a secure, pressure-tight closure that resists both forced entry and wind pressure, making uPVC casement windows one of the most secure openable window configurations available. For rooms that need both full-open and tilt-in ventilation options, see our uPVC Tilt and Turn Windows.

Durable Low-Maintenance uPVC Construction — Multi-chambered uPVC profiles with galvanized steel reinforcement resist moisture, corrosion, UV exposure, and temperature extremes without warping, rusting, or fading. No painting, polishing, or anti-rust treatment is required. A periodic wipe-down and light hinge lubrication is all that is needed to maintain full performance for 25–30 years.

Frequently Asked Questions (FAQs)

A uPVC casement window is a hinged window that opens outward or inward from a vertical side hinge, allowing the full panel area to swing clear of the frame for maximum ventilation. FabFrame manufactures uPVC casement windows in side-hung single, side-hung double, and top-hung configurations for residential and commercial projects.

Yes. FabFrame by Atul Glass manufactures, supplies, and installs uPVC casement windows across North India, including Punjab, Haryana, Himachal Pradesh, Uttarakhand, Jammu & Kashmir, and Chandigarh.

A casement window opens by swinging on a hinge, clearing the complete panel area for ventilation. A sliding window has panels that move horizontally on a track and typically opens only 50% of the frame width. Casement windows provide better ventilation per square foot of frame; sliding windows are better suited to spaces where swing clearance is limited.

Yes. The three-layer EPDM gasket sealing system on FabFrame casement windows compresses tightly on all four sides when closed, providing superior rain and wind protection compared to sliding windows. Top-hung casement configurations also allow ventilation during light rain without water entering the room.

The price depends on configuration — side-hung single, side-hung double, or top-hung — along with glass type, window dimensions, and hardware selection. Contact FabFrame for a customised quotation based on your specific project requirements.
