Type P louver door HS-27

The JAZO frame / door type P is usable with a full HS-27 safety ventilation louvre in the door. The safety ventilation louvre with 27% passage allows you to ventilate your room through the doors.

Ventilation through the doors is seen as a good alternative to ventilation in the walls. The number of architectural recesses can thus be reduced.
