 If your airplane is anything like my former ES, or my current IV
 (non-pressurized) you will find the door seal to be a critically
 important component of your airplane.  Not only does it have a
 significant impact on noise reduction in the cabin, it can affect speed
 as the lack of a door seal allows a significant volume of airflow from
 the cabin outward through the door/sill opening.  Depending on the
 tightness of that opening the airflow can be quite substantial.  The
 door seal remedies this issue totally.
 
 I tried to get a string going a while back concerning this same issue,
 but to no avail. I guess it is not an issue for many of you out there.
 While the door seal on my ES worked perfectly i.e. filled all gaps,
 reduced cabin noise significantly, remained sealed until I released air
 pressure, I am not having quite the same result with my IV.  My door
 seal inflates just fine, and holds just fine, up to approximately 220
 kts indicated.  Any faster than that, I begin to get a separation in the
 seal and the gap it is intended to fill, as the door is slightly sucked
 out by the airflow over the fuselage.
 
 Any thoughts, suggestions, ideas would be most welcome.

 Hello all,
 I'm having a little trouble fitting my door seal and was curious what
 other
 builders did or do?
