Aluminium single internal doors
Aluminium single internal doors are a clean, versatile solution for dividing internal spaces while maintaining light, flow, and architectural detail.
Manufactured using the Alu Space internal door system, single internal doors combine slim aluminium sightlines with the appearance of traditional steel doors.
Suitable for both residential and commercial interiors, single internal doors are made to measure and available with a wide range of glazing,
hardware, and design options.
A versatile solution for modern interiors
Single internal doors are ideal where a full-width opening is not required but visual separation is still important.
They are commonly used for:
- Home offices
- Kitchens and dining rooms
- Hallway transitions
- Utility rooms
- Commercial offices and meeting rooms
The slim aluminium profiles allow light to pass freely between spaces while providing privacy and acoustic separation when required.
