Door Air Sealing

Select sealants that:

are compatible with their intended surfaces,

allow for differential expansion and contraction between dissimilar materials,

meet the requirements of the applicable fire safety code (e.g., thermal or ignition barriers), and

for use inside the pressure boundary select low volatile organic compound (VOC) sealants that meet independent testing and verification protocols

Select:

pest-resistant materials that adequately support applied load and are permanent air barriers,

materials that meet the requirements of the applicable fire safety code (e.g., thermal or ignition barriers), and

low volatile organic compound (VOC) materials for use inside the pressure boundary that meet independent testing and verification protocols

Remove any material from the sealing area that will prevent full adhesion of the selected sealant

Remove any material from the sash contact areas that will prevent a tight seal or safe operation

Adjust door hinges and slab to properly fit the jamb and allow for ease of operation and security

Verify intentional drainage is functioning correctly

Adjust or replace handle, lockset, or strike plate so that door closes tightly without hindering safe operation of latching or locking mechanisms

Remove existing weather stripping and clean surface

Install continuous and complete weather stripping for sides and top of door so no visible gaps exist when the door is closed

Lap exterior weather stripping to channel water away from the door

Install a door sweep on the bottom of the door slab with no visible gaps when door is closed

Seal mechanically installed weather stripping to installation surface

Door operation may not be interfered with by any installation

Seal door stop to door frame

Replace any missing/damaged weatherproofing on exterior portions of door (seals, flashing, glazing, caulking, sealant, paint, etc.)

Seal any holes in frame left by abandoned hardware

Adjust and seal threshold as needed

Verify safe operation of door and all components

Where doors are required to have a fire-resistance rating, all weather strips and sealants applied to the door will be compatible with the listing of the door
