Why Choose Aluminium Patio Sliding Doors?
Sliding patio doors, also known as sliding glass doors, feature large glass panels with strong aluminium frames that glide smoothly along a track. These sliding doors open horizontally rather than swinging outwards, making them ideal for rooms with limited space. Aluminium sliding patio doors flood interiors with natural light and provide seamless access to the garden, making them a popular choice for small rooms and apartments.

Key features and benefits of sliding glass doors for patios include:
- Large glass panels that maximise natural light.
- Smooth gliding operation with high-quality rollers and tracks.
- Space-efficient design that doesn’t require clearance to open.
- Multi-point locking mechanisms fitted with robust locks and reinforced aluminium frames.
- Durable and low-maintenance sliding patio door frames.
- Enhanced thermal performance and energy efficiency with double glazing options.
- Toughened safety glass as standard, with optional laminated glass panels.
- Slim, durable aluminium frames and glazed units with built-in thermal breaks to retain heat and prevent draughts.
- Available in a wide range of colours, including anthracite grey, white sliding patio doors and dual-colour options.
- Bespoke, made-to-measure patio door dimensions to suit your openings.
Whether you’re installing new sliding patio doors or seeking an older external sliding patio door replacement, our stylish glass patio range is an excellent choice for both modern and traditional homes. Glazed patio doors with aluminium frames maximise light and provide easy access to your outdoor space, making a world of difference and adding real value to your home.
