Airtrak EA Eaves Ventilators
Application

  • Suitable for ventilating metal, membrane or liquid roof coverings.
  • 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.

Description

A range of profiles that provide a 25 mm ventilation path into the roof void at the eaves or edge of a flat roof.

Features and benefits:

  • Available with different vertical downstand (drip) dimensions for various locations such as drip edges to parapets, dormer roofs, flat roofs etc.
  • Can be combined with Airtrak CF ClipFast clips where it is possible that the flashing might slip off the ventilator over time and the welt disengage from the lower edge.

Applications:

  • Suitable for ventilating metal, membrane or liquid roof coverings.
