Casement Doors

uPVC Casement Doors for Every Room and Requirement

Among all door types, the casement delivers the highest ventilation per opening. Hinged on the side and swinging fully open, a upvc casement door provides 100% clear access, more airflow, more light, and more flexibility than a sliding configuration can offer. From single entrance doors to French glass doors and purpose-built washroom doors and institutional entry/exit points, uPVC casement door variants address a wider range of room types and applications. The right choice for upvc doors starts with understanding which casement pattern fits the space.

Casement Door Patterns That Match Your Space

Griham's casement door range covers seven distinct patterns, each built for a specific application and user requirement.
Single Openable Door The most widely specified uPVC casement door for residential entrances, balcony access, and internal room openings. Hinged on one side, it swings fully open to deliver 100% ventilation and maximum airflow. Available with multi-point locking for enhanced security and large glass panels for natural light. Suited for bedrooms, living rooms, villas, offices, and showrooms.

French Door (Glass) A double-panel uPVC glass door that opens from the centre, creating a wide, light-filled opening with a classic architectural presence. Among all upvc door styles, the French door is the most considered choice for living spaces that open onto balconies, gardens, or terraces where the door itself is as much a design feature as it is a functional element. Because the whole panel is glazed, glass choice matters even more here. For strength and safety in such a large, wide-opening glass panel, uPVC doors with toughened glass are the natural starting choice. uPVC doors with frosted glass work particularly well as a more private alternative.

Single Panel Door (PVC) for Washrooms and Commercial Usage A purpose-built uPVC casement door variant with an integrated high-strength PVC infill panel rather than glass, offers superior structural rigidity, an opaque finish, and complete privacy, making it the right choice for bathrooms, utility areas, and commercial spaces where a glass panel is neither practical nor appropriate.

French Panel Door (PVC) The double-panel format of the French door with PVC infill in place of full glazing. Delivers the same wide, centre-opening access and symmetrical presence while keeping the opening opaque, suited to service entrances, utility rooms, and back-of-house openings where the width of a French door is wanted but visibility is not desirable.

Single Openable Door (Glass + PVC Panel) A single hinged door that combines both materials in one leaf: a glazed upper section for natural light and a PVC panel below for strength and privacy. The most practical uPVC casement door specification for kitchen, utility, and rear entrances, where the lower half of a door takes the most wear and the upper half still needs to bring light in.

Double Openable Door (Glass + PVC Panel) A double openable door carries the same glass-and-panel construction across two hinged doors that open from the centre. Two doors create a wider opening than one, while the panelled lower section keeps its durability. This makes it a practical choice for main entrances, service yards and commercial usage.

Single Openable Door (No Threshold) The single openable door is also offered without a base threshold, so the bottom sits flush with the floor and movement across the doorway stays smooth. Griham positions it as a barrier-free option for seniors, children, and high-traffic spaces.

Threshold vs Without Threshold — Why It Matters

Every upvc casement door can be specified with or without a threshold at the base of the upvc door frame. The threshold variant provides a complete seal at the bottom making it the right choice for external openings where weather resistance, dust ingress, and water seepage are primary concerns. The without-threshold option creates a flush floor transition, improving accessibility and enabling a seamless flow between spaces. For internal room openings and commercial spaces where step-free access matters, the without-threshold configuration is the more practical specification. Whichever option is chosen, the underlying profile stays the same: a four-chambered system that keeps strength and thermal performance consistent no matter whether a threshold is specified or not.
