air leakage thru exterior door lock sets
 

Is there anything that can be done to minimize infiltration/exfiltration thru lock sets in exterior doors? Might there be types/styles of sets that are/can be "sealed" better that others? Haven't found much info myself yet. I only know as many point sources of air leakage are sealed other lesser leaks can greatly increase under pressures, becoming more significant.

I agree with you, as you tighten up your vapour barrier the little leaks become more obvious. Electrical devices, especially receptacles, are another issue.

I remember when R2000 homes first came along that there was an urban legend about warm moist air pushing into your door locks, condensing, then freezing and "locking" you into your house.
