How to airseal an outswing exterior door?

harrison55 | Posted in Green Building Techniques on

We have three 3’0 X 6’8 outswing exterior doors to install.  The jamb of the door needs to seal to the Zip sheathing, but I am concerned that I might still have an air leak through the strike plate.

Can anyone give me guidance or instructions for airsealing an outswing door?

    Hi Mark -

    Conductive and convective heat loss at door handles/locksets are bedeviling. But you should be able to continuously run a gasket along the door stop into which the door will set?

    I am might be missing something in your door configuration (must admit I don't follow "jamb of the door needs to seal to the ZIP sheathing" - this means you have no door frame?). Perhaps an image--even a hand-drawing would help.

      Peter,

      I think Mark is worried that if his air-sealing layer is the outside of the frame, that with an out-swing door the strike plate affords an opportunity for air to bypass it.

      I'd suggest that a combination of canned-foam and taping the interior of the frame to the studs should work.

    I would imagine most door stops are, but making sure that it is air tight to the jam would also matter depending on location of door seals. If its a simple continuous jam, seems like sealing/taping the inside jam to frame as Malcolm suggests would seal up any potential by-pass in any of those locations.

    Thank you, gentlemen. Foam is the answer.

    How is the door protected from the weather? Are you installing a door sill pan?
