Exposed duct through decorative wall

Feature penetration

ConnectionContinuous duct or concealed coupling
SupportSupports on both sides

Before you start

  • Confirm whether the wall is rated, weather-exposed, acoustically treated, or decorative only.
  • Coordinate the exact finished opening, trim or escutcheon, wall thickness, sealant appearance, and support locations.
  • Inspect the wall finish and protect it before moving duct through the opening.
  • Verify the joint will not be hidden inside the wall unless the approved detail permits it.

Tools and materials

Exposed duct section, approved sleeve or edge protection when required, finished trim ring or escutcheon, supports on both sides, nonmarking protection, laser, level, approved sealant, cleaning materials, and touch-up products for the wall and duct finishes.

Lay it out

  1. Mark the duct centerline on both faces of the wall.
  2. Confirm the finished reveal and trim-ring position before cutting or setting the opening.
  3. Check the route and support locations on both sides.

Set and support it

  1. Support the duct independently on both sides of the wall.
  2. Protect decorative edges and keep the duct centered.
  3. Do not let the wall opening carry duct weight.

Make the connection

  1. 1

    Verify the finished opening dimensions and edge condition.

  2. 2

    Install any approved sleeve or protection.

  3. 3

    Pass the duct through under control without scraping the wall or finish.

  4. 4

    Center and support the duct on both sides.

  5. 5

    Install the approved trim or escutcheon evenly.

  6. 6

    Apply the required seal neatly and continuously.

  7. 7

    Clean the duct, wall, and trim.

Check the install

  • The duct is centered in the opening.
  • The trim ring sits flat and the reveal is even.
  • The wall carries no duct load.
  • The sealant line is neat and appropriate to the detail.
  • No wall or duct finish damage remains.

Common mistakes

  • Treating a rated penetration like a decorative opening.
  • Installing trim before the duct is centered.
  • Letting the opening support the duct.
  • Leaving a visible joint or rough seal inside the feature wall.

Stop and ask

Stop if the penetration is rated, waterproofing or acoustical treatment is unresolved, the finished opening is wrong, or the trim and seal detail has not been approved.
