Mechanical differences between double glazed uPVC doors are primarily influenced by the type of door and its specific features, which determine the hardware, operation, and installation requirements. Each door type is designed to suit different functional and aesthetic needs, resulting in variations in their mechanical components and mechanisms.

For instance, hinged uPVC doors, which are the most common type, typically feature hinges mounted on one side, allowing the door to swing open and closed. These doors often include multi-point locking systems for enhanced security, as well as handles and hinges that are specifically designed to support the door’s weight and ensure smooth operation. In contrast, sliding uPVC doors operate on a track system, requiring rollers, guides, and a different locking mechanism that allows the door panels to glide horizontally. Sliding doors are ideal for spaces with limited room for door swing, such as patios or balconies.

French uPVC doors, which consist of two hinged doors that open from the center, often feature a central locking system that secures both doors simultaneously. They may also include espagnolette bolts that extend into the frame at the top and bottom for added stability and security. On the other hand, bi-fold uPVC doors are designed with multiple panels that fold and stack to one or both sides. These doors require specialized pivot hinges, tracking systems, and a unique locking mechanism to ensure smooth folding and alignment. Bi-fold doors are popular for creating wide openings, such as those leading to gardens or large indoor-outdoor spaces.

Despite these mechanical differences, all uPVC doors share several common advantages. They are highly energy-efficient, thanks to their excellent thermal insulation properties, which help reduce heat loss and lower energy bills. uPVC doors are also known for their durability, as they are resistant to weathering, corrosion, and rot, making them suitable for various climates. Additionally, they require minimal maintenance, as they do not need painting or varnishing and can be easily cleaned with soap and water. Furthermore, uPVC doors offer customisable design options, allowing homeowners to choose from a variety of colors, finishes, glazing options, and hardware to match their aesthetic preferences and functional needs.
