AirSill™

York's AirSill™ aluminum flashing receivers provide an alternative to traditional installation methods for flashing attachment at wall openings.

  • Provides a method of attaching fenestration perimeter flashing (e.g. sill, jamb, and head) without interrupting critical fenestration perimeter seals to the air barrier.
  • A two-piece system consisting of a receiver and a clip
    1. Install the receiver to the backer wall
    2. Install brake metal flashing into the receiver
    3. Install clip into the receiver, which holds flashing in place
  • Allows damaged flashing to be removed without interfering with the fenestration assembly.
  • Easily integrated with the air barrier assembly and is ideal for fenestration collar flashing applications.
  • Eliminates the need for difficult collar flashing brake metal corner splices.

  • Provides an alternative method for attaching flashing that does not interrupt critical seals to the air barrier
  • Eliminates the need for fasteners in sill conditions that are more prone to water penetration
  • Flashing secured to the vertical wall (vs. opening) so that fenestration can be installed before or after exterior cladding
  • Creates flexibility in construction sequencing
  • The installation method allows for quicker “dry-in” of the building enclosure. Interior materials can be installed simultaneously with exterior cladding
  • Removable flashing installation method
