Altherm APL Architectural Series Sliding Doors

Title Title


Sliding doors slide on an outside track and can meet at 90° corners without the need for a corner post. For most configurations a fixed side panel is required. However, a bypass slider option is available where two or three panels move.

The sliding door system has also been designed for convenient use as a cavity slider or for sliding back over a wall.
