Application

  • Suitable for all roof coverings up to 4 mm-thick including liquid applied, single ply membranes and fully supported metal 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

Abutment ventilator for fully supported metal, membrane and liquid applied roofing.

Features and benefits:

  • Stainless steel profile providing ventilation at the interface of a fully supported metal, membrane or liquid applied flat roof with an abutment such as a parapet or building wall.
  • Includes an integral fly screen and spacer feet to provide a continuous strip of ventilation to the roof void as required by current Building Regulations.
  • Requires a cover flashing in a suitable material.

Applications:

  • Suitable for all roof coverings up to 4 mm-thick including liquid applied, single ply membranes and fully supported metal roof coverings.
