The main differences between PSK, HST and SMART-SLIDE are:
- Opening method:
- HST: the window rises a few millimeters and moves
- PSK: the window opens and moves, hiding behind the fixed sash
- SMART-SLIDE: the window opens and moves, hiding it behind the fixed sash
- Threshold height:
- HST: thresholdless
- PSK: has a threshold (the height depends on the profile)
- SMART-SLIDE: has a threshold
- Size:
- HST: large
- PSK: average
- SMART-SLIDE: medium
