ISO 9001 Quality Management
Certificate type
Range of ventilators providing 25 mm ventilation over the layboard into the roof void.
Application
- Suitable for use with lead and hard metal roofing for a range of ventilation details.
- E Version: For increased resistance to both wind uplift in exposed locations and corrosion in coastal locations, the ventilator 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.
- FR Version: To reduce spread of fire through ventilation apertures, the ventilator can be supplied with an intumescent seal.
Note: Standard AIRTRAK® details assume moderate weather conditions. Small amounts of moisture may be admitted under heavy storm conditions. Where more severe weather conditions are likely, consideration should be given to increasing the vertical overlap dimension to upstands and to slating or tiling to improve the integrity of the weathering detail. For slate and tile details the manufacturer also recommends the use of the AIRTRAK® LPS where appropriate. Contact manufacturer for further technical help.
