Masons Passive Roof Ventilation System is a complete system for ventilating roof cavities in long run metal roofs. Using the natural stack effect and wind movement, this passive system helps remove warm, moist air and introduces cooler, drier air to protect the roof structure, insulation, and ceiling space from moisture-related damage.
The improved weather and air tightness of modern roof cladding and flashings contribute to warm, dry and healthy homes. But, the reduced airflow in the roof attic space can create a hidden problem – excess moisture and condensation in the roof space.
Without adequate ventilation, moisture builds up, creating the perfect conditions for mould growth. Good roof space ventilation is crucial in preventing this.
THE SYSTEM INCLUDES:
RIDGE VENTS to let warm air escape
VENTILATED ROOF BATTENS to create airflow under the roofing
INSUL-BAFFLE to preserve a clear air path near the eaves
