Vent-A-Roof, available from Lysaght, is an innovative metal roof ventilation system that promotes the circulation of fresh air through roof spaces, ceilings and building spaces in commercial and light industrial buildings, residential homes and most metal sheds.
Marketed and distributed by Lysaght, Vent-A-Roof is a passive ridge ventilation system that offers an aesthetically-appealing alternative to traditional ventilation systems such as whirlybirds, powered vents and commercial ridges on metal roofs.
With no moving parts, the metal roof ventilation system provides the assurance of long term reliability and durability. Vent-A-Roof utilises fundamental airflow principles to improve roof ventilation, thereby cooling the roof space and mitigating condensation, humidity, mould and mildew.
“Vent-A-Roof uses the exact same thermal principles as other natural ventilation systems. As the roof space heats, hot air is drawn towards the highest natural point and expelled through the Vent-A-Roof integrated louvre and down the pan creating a passive, natural and continuous flow of air,” explained Tony Jamieson, Lysaght’s national specification manager.
“Simultaneously, any positive airflow across the ridge of the roof creates a negative pressure, which pulls air out from the ridge vent and brings in fresh air from intake vents in the eaves or below. Essentially, the two thermal effects create a continuous flow of air allowing cool air into the roof/building space and extracting hot air.”
The patent-protected Vent-A-Roof system is NCC and BAL-compliant and suitable for use in cyclonic regions and bushfire-prone areas.
The system is compatible with Lysaght’s CUSTOM ORB, TRIMDEK and KLIP-LOK 700 profiles and is available in all COLORBOND steel colours with two common ridge designs, roll-top or low profile folded ridge, providing an attractive and uniform look.
Vent-A-Roof is available nationally from all Lysaght branches.
