AIRTRAK® standard

roof void ventilators


With a greatly expanded range of standard ventilators now available, the AIRTRAK® ventilators cover most of the commonly encountered ventilation details. All ventilators are supplied in convenient 1m lengths which can be trimmed to length and mitred at corners on site.


roof void ventilators for exposed and coastal locations


For increased resistance to both wind uplift in exposed locations and corrosion in coastal locations, the Airtrak ventilators can be supplied in 1.0 mm-thick, 316 grade stainless steel. Where extreme weather conditions are likely, consideration should be given to providing more weathering cover to upstands and slating or tiling to improve the integrity of the detail.


fire resisting roof void ventilators


The AIRTRAK®-FR ventilators incorporate an intumescent seal that activates in the instance of fire or at temperatures of 180-200°C. These ventilators will effectively close off ventilation apertures up to 25mm and help to control the spread of fire.
