Aluman S31 sliding door

- Savings,
- Efficiency
- Aesthetics

S31 is Aluman's first sliding door system without thermal break, developed with three primary criteria: economy, efficiency, and aesthetics.

The S31 is perfectly suited for use as a sliding window, combined with the fixed panes of the DW50 system.

The S31 can also serve as a sliding door with a maximum door height of 3m, door width of 1.5m, and a door weight of 150kg.

Thanks to its EPDM sealing strip, the S31 provides excellent insulation.

The S31 offers a sleek and stylish design with various intermediate bar options.
