According to the Technical Building Code (TBC), for a proper air quality, circulation must keep a minimum ecxtraction and admission air flow. JNCN Doors have developed AIRDOOR system: concealed ventilation system that allows air passage and sound insulation according to the Technical Building Code.
This innovation, patented by JNCN, was created to keep the aesthetic design of the door while having a correct ventilation and sound insulation. This system helps integrate our technical needs with the design in the room.
It also allows us to keep the standard dimensions in all the elements without altering the door leaf, door opening and door subframe dimensions and to keep the same assembly of a standard door set with no ventilation system.
AIR CIRCULATION AIRDOOR SYSTEM
AIRDOOR system provides rooms with air circulation by letting saturated air escape through the head of the frame.
Patented system for aireation between rooms according to TBC. Model 1.0710887
