JNCN airtight door permits the complete sealing of all the edges of the door with frame and floor. Devices filling the total perimeter are used for this purpose: gum seal in top and side edges and drop seal on the door base. Thanks to this sealing, noise, odours and smokes are significantly reduced in rooms.

Drop seal: automatic. The system will activate when closing the door by closing the gap in the bottom of the door.
Gum seal: airtight system in the sides and top of the door. This is installed in the frame, and apart from insulating, it prevents from the door slamming noise.
Door thicknesses: acoustic insulation will increase depending on the door thickness (35mm = 29dB / 40 mm = 30 dB / 45 mm = 31 dB).
