HONG provides air circulation in the space between the ceiling and outer roof, and removes very hot air which increases room temperature in your home or factory.

Effective roof space ventilation includes Eave vent usually installed under the eave to draw in fresh outside air, and HONG ventilator to exhaust the superheated and moisture laden air.
